Farm diversification – diversifying for farm resilience

Farm diversification can be a great way to add another stream of farm-based income and increase farm resilience. But how do you go about it, find the right idea and courage to pull it off successfully?

Farm diversification featuring in new Keep Agile Keep Farming podcast episodes 

Do you think you have a crazy idea to diversify your farm? In a special of the Keep Agile Keep Farming podcast with two episodes (episodes 3&4) on farm diversification we talk to Victoria Galligan the Editor of the Farm Diversity Magazine and Celia Gaze, Founder of The Wellbeing Farm, which is a farm diversification in Lancashire, United Kingdom that won multiple awards.

Two ladies who have seen and gone through a lot when it comes to farm diversification. We gain insights on trends and how farmers are adapting to current changes and opportunities.

Celia who has gone through the rollercoaster of farm diversification first-hand shares some important do’s and don’ts from her experience and how crazy ideas can change your life and a farm for the better. She is also the author of the book: “Why put a bow tie on a llama?” published in 2020.

Definition of farm diversification

Farm diversification is most commonly defined as “the introduction of a non-traditional source of income into the pre-existing farm business”. Agricultural diversification includes the introduction of additional farming enterprises (eg. beef cattle, aquaculture or tomato growing). Non-agricultural diversification, involves incorporating non-farming activity into the farm business (eg. farm-based accommodation, on-farm processing of food, leasing land for non-agricultural purposes).

Why are farms diversifying?

Figures released at the beginning of 2020 revealed that more than half of England’s 57,000 farms have diversified.  A study carried out in the UK revealed that for six out of ten farming families increasing income was the most important reason for diversifying.

Similarly, a study carried out in the United States reported that 61% of farming families diversified for economic reasons, 23% for reasons external to the existing business and 16% for social reasons. Another driver was to increase the value of the farm for its transition to the next generation.

Many forms of diversified activity on the one hand have a far smoother or more steady income profile. On the other hand  they can offer an alternative market for existing agricultural products (e.g. on-farm shops).

In general farm diversification aims to spread risk and smooth cashflows, both of which add value to the farming business by improving and strengthening the economic viability of the business.

Barriers to farm diversification

Connectivity (digital) is still a key barrier in remoter rural areas. Perceived risks in the use of online tools and the costs associated with technology adoption are also barriers.

Innovation and technology adoption are key enablers behind farm diversification. Therefore, the capacity of farmers to capitalise on both farm diversification opportunities and grant-seeking activity may be supported or constrained by access to and skills to absorb and use new technologies. This again to some extent is also influenced by age and education of key decision makers on the farm.

Resilience in pigs – New benchmark to reach genetic potential

Studies have shown that pigs within a commercial grow-finish environment only achieve 70% of their growth potential compared to pigs reared in a less challenging and unrestricted research environment. Researchers have highlighted this 30% gap in pig performance as a key area for improvement using both management and genetic selection to reduce the impact of stressors on pigs reaching their genetic potential under commercial conditions. There are indications that improving the ability of pigs to cope with stressors may be a better way of improving pig performance than selecting only for increased growth potential from pig genetics researchers. Resilience in pigs has been described as the ability of pigs to cope and recover from stressors and is on the cusp of becoming a new benchmark in pig production.

Why resilience?

Average daily gain is a function of the pig’s production potential as well as the ability of the animal to cope with stressors and unforeseen challenges. Breeding and management strategies that result in more resilient pigs, will increase the capacity of pigs to reach their genetic potential under commercial conditions and improve production efficiency on farms in a sustainable way. Furthermore, it is expected that resilience research will benefit the health and welfare of pigs and reduce the use of antibiotics or treatments in general on pig farms. An economic value associated with improved resilience in pigs beyond reduction in production losses and health costs is a reduction in labour time and costs, as animals show less problems and become easier to manage.

The response of a pig to stressors in terms of minimizing the impact of a stressor and quickly recovering from it is defined as resilience. So, the capacity of the body to withstand challenges to its stability is considered as resilience.  There are many different types of stressors a pig can potentially encounter throughout its productive lifetime, which again can impact its performance. Quite often the first noticeable impact of stressors will be a reduction in feed intake in pigs. However, there are also reactions on the cellular and gut level of the pig, such as oxidative stress and inflammation in response to stressors, further reducing the available energy for growth, as those type of stress reactions will increase requirements for maintenance energy.

Ultimately the pig’s capacity to adapt efficiently will determine the extent of those stress reactions and the impact they will have on growth performance over time.  A meta-analysis study by Pastorelli et al (2012) across 122 published pig trials, studying the impact of selected stressors found under commercial conditions on reduction in average daily growth rate. The researchers also looked at how much of the reduction in growth rate was due to an increase in maintenance energy and how much was related to a reduction in feed intake.  According to this data some stressors, such as respiratory disease, lipopolysaccharides (LPS) and mycotoxins have a greater impact on feed intake than maintenance energy requirement. This might also be expected from heat stress. Whereas when it came to challenges associated with the gastrointestinal tract, a large part of the reduction in average daily gain was due to an increase in maintenance requirements. Other stressors which were not covered by this study are: human handling, vaccination, dust, ammonia or out of feed and water events, which can all also have an impact on performance of pigs to a greater or lesser extent.

Spotting resilience in pigs

Single time-point measurements have been said to be of limited value because they do not measure responses to and recovery from stressors. Although there are exceptions, such as productive longevity as it is a single measurement of the accumulated consequence of adaptive capacity and resilience. Otherwise repeated measurements over time have been found to be key to determine resilience in animals. This is where new technologies, such as automated monitoring, sensors and computer vision come into their own greatly facilitating the ability of producers to collect data from repeated individual measurements in pigs on farm. It is also making the recording of individual feed intake in group-housed pigs more accessible, which would otherwise be difficult to do on farms.

Recently several research groups have taken different approaches to measuring resilience in pigs, some using production data, some behavioural data and others are currently using artificial intelligence to monitor tail posture in pigs. But what they all have in common is, that they are looking at repeated observations to detect the number of fluctuations or deviations from an expected standard over time. Some suggest that the individual day-to-day variation in feed intake could be utilized to quantify resilience to heat stress, whereby pigs with more day-to-day variation in feed intake would indicate that pigs are less resilient.

Genetic researchers in the US confirmed that fluctuations in feed intake or duration at the feeder over time are indicators for resilience in pigs to a variety of stressors, including disease and can be used as heritable measures of general resilience in pigs. The variance of deviations in daily feed intake and deviations in daily duration at the feeder during the finishing phase were positively genetically correlated to mortality and number of treatments required in pigs. A pig welfare research group from the Netherlands are using the pig’s tail posture and intactness as the main indicator for resilience. The theory behind it being that more resilient pigs are less inclined to start tail biting and this is also related to tail posture – curly versus straight.

Managing for resilience in pigs

Geneticists have certainly started to pave the way to breed more resilient pigs by determining phenotypic parameters that are suitable as resilience indicators. Behavioural research is highlighting the opportunity to improve resilience in pigs through management practices, such as enriched housing. In piglets the location of sow feeders during lactation have been shown to matter in the piglet’s ability to adapt to the weaning process.

Nutritional solutions that help to build the adaptive capacity of the pig to stressors for more energy efficient responses could also play a role in managing resilience. For sure more research is underway to gain a better understanding of how nutrition and other management practices can effectively support pig resilience.

Closing remarks

The resilience approach requires us to make a shift in how we evaluate the impact of breeding and management strategies in pigs. While the proposed resilience indicators are not always easy to measure under commercial conditions using conventional practices, the development of new technologies helping farmers to monitor individual animals for precision livestock farming is certainly speeding up progress required to facilitate this.

This approach also highlights the need for adaptability to future events over optimization and improving efficiency under known conditions for pigs and farms. There is no time like the present Covid 19 crisis to remind us of the uncertainty and unpredictability in our lives and farming, bringing home the need for resilience.

Какие вопросы будут освещаться на вебинаре:

Транзитный период — это тяжелое время для молочных коров. Основные физиологические, метаболические и иммунологические изменения происходят в течение этого периода времени, когда производственный цикл коровы переходит от гестационного состояния без лактации к началу обильного синтеза и секреции молока. Около 30-50% молочных коров страдает метаболическими или инфекционными заболеваниями, такими как молочная лихорадка, кетоз, задержка отделения плаценты и мастит и др. Высокая распространенность метаболических нарушений и заболеваний в период отела подчеркивает тот факт, что многие системы не обеспечивают адекватных решений и перегружают адаптационные возможности своих коров.

Татьяна Чупина, управляющая фермой ООО «Вакинское Агро», г. Рязань, имеет 24-летний опыт управления фермой, а также кормления жвачных животных, считает: «Большинство молочных ферм сталкиваются с одними и теми же проблемами в транзитный период».

На вебинаре Татьяна Чупина поделится своим практическим опытом и расскажет о том, как успешно пройти транзитный период с помощью тщательных методов управления, правильного кормления и мониторинга.

Последние исследования подтверждают, что основные механизмы, усугубляющие метаболический стресс и вызывающие нарушения здоровья у молочных коров в транзитный периода, являются следствием измененного метаболизма, окислительного стресса и воспаления. Наш второй спикер Доктор Рената Брейтсма расскажет, как повысить адаптационную способность коров с помощью рациона, влияя на воспалительные процессы и снижая окислительный стресс в транзитный период.

Weaning-to-first service interval in sows fed a gut agility activator

The weaning-to-first service interval is a key driver for improving farrowing rate and increasing litter sizes in subsequent litters. Heat stress is one of the factors that is known to have a significant impact on weaning-to-first service intervals. A gut agility activator was evaluated in commercial sow diets for response in sow reproductive performance post weaning in a hot climate.

Factors affecting the weaning-to-first service interval

Weaning-to-first service interval is economically relevant since it affects the number of non-productive days and hence maintenance cost and sow efficiency. Whereas estrus detection methods and the capabilities of breeding technicians play an important role for weaning-to-first service interval, there are other factors that need careful management and optimization to ensure short weaning-to-first service intervals in sows.

Lactation length for example needs to be optimized, since the shorter the lactation period the more likely the weaning-to-service interval is increased. Adequate feed intake, especially during the first 7 to 10 days of lactation, is key to replenish body reserves which controls subsequent reproductive performance. This is also why many studies have demonstrated that high ambient temperatures prolong weaning-to-first service intervals and reduce pregnancy rates, because they impact sow feed intake in lactation. Hence why ventilation design and supplemental cooling systems in the farrowing room and adequate water intake can also play an important part.

Impact of heat stress on weaning-to-first service interval

Researchers reported weaning-to-first service intervals of 2 to 4 more days in sows experiencing temperatures >35°C versus <30°C. Others showed that a high temperature humidity index (THI > 82) resulted in a greater percentage of gilts and sows with a weaning-to-service interval >8 days. This has been explained to be partly due to a reduction in feed intake in response to high temperatures, particularly during lactation.

More recent studies measured the impact of heat stress in sows on oxidative status at different stages of the reproductive cycle and reported increased oxidative stress in sows around late gestation in sows kept under temperatures above 25°C compared to sows kept at more moderate temperatures. This was associated with a reduction in reproductive performance in the form of a decrease in litter size at birth and litter weaning weights. Increased oxidative stress could however also lead to an increase in inflammatory responses in the sow and an increase in maintenance energy, which again could have an impact on subsequent weaning-to-first service interval.

Effect of Anco FIT on post-weaning sow reproductive performance

The gut agility activator Anco FIT was tested in a sow trial designed to evaluate the product for its impact on annual sow reproductive performance post-weaning on a commercial sow farm in Cordoba, Argentina.

Trial design

Anco FIT was added to sow gestation and lactation diets for a whole year starting in September 2019 on a commercial sow farm with 380 sows. Monthly post weaning KPIs (key performance indicators) for sows, such as weaning-to-first service interval and percent of sows returning to oestrus (when a sow was mated but did not become pregnant), were monitored until August 2020. No other dietary changes made. Performance was compared to that in the previous year, where there was no Anco FIT in the sow diets.

Results

Adding Anco FIT to the sow diets reduced annual means for weaning-to-first service intervals by 31% (11.6 vs 8.0 days) and returns to estrus by 24%. The improvement seen in returns to estrus was particularly marked in the summer months (November to March) of Argentina (10.4% vs 6.3%).

Conclusion

Feeding Anco FIT to sows during gestation and lactation improved key annual post-weaning reproductive performance parameters in sows and the impact was particularly measurable during the hotter summer months in Argentina. Results may to some extent be explained by improving sow lactation feed intake under heat stress as shown in a previous sow lactation trial with Anco FIT.  On the other hand, Anco FIT includes components with antioxidative properties, which might have helped to reduce the negative impact of oxidative stress in sows at crucial stages of the reproductive cycle and make more energy available for reproductive performance.

Plant extracts in animal feed – Why formulation matters

Plant extracts are often all thrown into the same pot, when in fact there are many different types of herbs and spices that could be used in products formulated for the use in animal feed. Plus, there are a multitude of possibilities to combine them and additional factors that will differentiate products containing plant extracts formulated for the use in animal feed. So, the reality is they are not all the same.

The type and combination of plant extracts is only one of the factors that determines the function and effectiveness of what is currently sold into animal feed as “plant extracts”.  What looks promising in an in vitro experiment might not always be practical and cost-effective in vivo.  The question will always be: have the plant extracts been tested at different dosages in the animal and in what species?

Here are 3 of the key factors that need to be considered when formulating and designing feed solutions based on plant extracts.

1.Function

Herbs and Spices have many different bioactive components with different properties and functions. Even their essential oils can have something like 80 different components. Plants have evolved to cope with stressors and many of these components have a protective role supporting the resilience of plants, but they also evolved to attract pollinators to propagate. So, when you combine plant extracts derived from a number of different herbs and spices you can have a all cocktail of bioactive substances and their effect will ultimately also be determined on synergistic effects and not just concentrations of individual components. New research technologies have facilitated a more in depth understanding of the mode of action of plant extracts and their components at the animal level. As a result, it is now possible to formulate plant extracts with a more accurate idea of the outcome for their function in the animal and animal response, rather just working in a black box approach. This is speeding up the process of product development and evaluation. It also provides more potential for differentiation in function between products through formulation know how within the category of plant extracts.

2.Taste

Most plant extracts have sensory properties and they come with a distinctive flavour. That in itself can determine how effective the product will be and how much of it you can apply to animal feed, because the flavour can affect feed intake not just in a positive way.  For example, plant extracts with a strong bitter taste can lead to a lower acceptance of feed in pigs. Again, this will depend on dosage, but is it possible to apply the dosage required to achieve the desired effect in the pig without having a negative impact on feed intake? Only in vivo dose response trials will provide the answer. So, it is important to understand which plant extract compounds might have a negative impact on feed intake and find ways to determine the acceptable dose or mask their taste.

 

3.Concentration/dosage of plant extracts

Concentrations of individual components in the formula and concentrations ultimately added to the feed determine the dosage required to achieve the desired response in the animal. Dose response trials are required to determine the optimal and most cost-effective dosage. As is the case with other types of feed additives more is not always better in terms of performance, but there will be a minimum dose required to have an impact on the animal.

These are only some of the factors to consider when formulating products with plant extracts. But they highlight that how they are formulated matters, and the buck stops with the animal.

Dairy farming resilience – three reasons to keep your cows agile

Feeding cows for adaptive capacity in the transition period – 

Anco FIT Farm – weniger Stress durch robustere Tiere

Resilience in dairy cows – feed for adaptability

It is possible to breed for resilience in dairy cows. But is it possible to feed for it? What are the nutritional options?

Farm resilience

Resilience is a concept that acknowledges unpredictability and emphasizes the need to enable adaptability and transformability of systems instead of optimizing them. A farm management approach based on resilience comes up with systems and solutions that can absorb and accommodate future events in whatever unexpected form they may come.  It follows that resources are allocated to strategies that allow reducing the impact of a wide variety of potential unknown events and on identifying emergent opportunities.

Farm resilience is characterized by the ability to:

(1) constantly evolve while protecting against shocks to the system

(2) readjust to adapt to stressors

(3) to implement strategies to take advantage of strengths

and (4) to continually adapt to the current situation (Darnhofer 2009)

Increasing diversity and adaptive capacity of farm systems have been highlighted as key drivers to improve farm resilience and the ability of farms to cope with different types of disruption and stressors.

Farm resilience starts in the cow

In a dairy production system, farm resilience also depends on how well cows can cope with unforeseen challenges in their feed and their environment. As the cow is an integral part of the system, she is expected to be resilient and less sensitive to stressors and sub-optimal circumstances. This is because less resilient cows will have greater fluctuations in their milk performance and quality leading to a decreased cost-effectiveness of dairy rations and a lower likelihood of reaching performance targets. Consequently, fluctuations in farm profits are bound to occur.

Lower resilience in cows can also lead to increased susceptibility of disease which can cause further losses in the long run. More resilient cows put fewer constraints on new farming systems and require fewer drugs, without compromising health or economic efficiency and are less likely to be prematurely culled. This again affects the sustainability and long-term profitability of the dairy sector.

Resilience in dairy cows – advantages

  • more flexibility and adaptive capacity for the farm system
  • greater consistency in milk production
  • greater consistency in milk quality
  • longer production lives, longevity
  • more stable farm incomes
  • fewer treatments and drugs
  • easier to manage cows and reduction in labour time
  • improved cow welfare

Resilience in dairy cows depends on adaptive capacity

Resilience is determined by how the cow responds and adapts to stressors or in other words by her adaptive capacity.  The transition period for instance is a critical time that requires a high capacity to adapt to lactation. But milk production and quality will also depend on how the cow responds to other stressors, such as heat and mycotoxins. Most stressors will provoke stress reactions in the form of reduced feed intake, oxidative stress, inflammatory responses or changes in rumen efficiency. The extent of these stress reactions is determined by the adaptive capacity of the cow, which again determines the impact stressors can have on key performance parameters, health and longevity of the cow and how quickly she recovers.

Gut agility – feeding for adaptive capacity

Nutrition can play an active role in management strategies designed to reduce the impact of stressors on dairy cow well-being and performance. New nutritional concepts, such as gut agility activators, are designed to support the adaptive capacity of dairy cows for improved resilience.

Що очікувати

2020 рік здавався перспективним для світової галузі птахівництва, однак пандемія Covid-19 в поєднанні з несприятливими умовами в деяких регіонах України призвели до значних наслідків для птахівництва. Криза змусила виробників зменшувати витрати на годівлю, підвищувати цільові показники ефективності та прикладати додаткові зусилля для більш ефективного перетворення кормового протеїну у чистий приріст. Оскільки на корми припадає понад 50% виробничих витрат, зниження щільності поживних речовин у раціонах, використання альтернативних джерел сировини, використання дешевих, але низької якості інгредієнтів є загальноприйнятими способами зниження собівартості кормів. Однак все це може призвести до погіршення біологічних показників і, отже, до зниження загального прибутку.

Кормові інгредієнти з низькою якістю (мікотоксини, антипоживні речовини, окислені жири), дієти з високим вмістом енергії та зміни у складі кормів є типовими стресорами у птахівництві, і всі вони здатні викликати запальні реакції в кишечнику. Хронічне запалення є ключовим фактором зниження продуктивності стада, збільшення захворюваності та смертності, що спостерігаються у птахівництві, та збільшення бактеріального забруднення м’яса. Протягом багатьох років ці проблеми контролювали за рахунок використання антибіотиків, додаючи їх в корм в якості  стимуляторів росту (AGP), які, окрім антимікробної дії, також зменшують запалення низького рівня. Однак виробництво продукції птахівництва, без використання «AGP», під тиском споживачів, стало викликом птахівничій галузі в напрямку ефективного контролю стану здоров’я та підтримки високих стандартів продуктивності.

У цьому вебінарі доктор Рената Брейтсма розгляне, як нові концепції годівлі, призначені для підтримки пристосованості птиці до боротьби зі стресовими реакціями, можуть природно сприяти стабільнішим доходам, довше підтримувати більш високу продуктивність у курей-несучок та зменшувати потребу у використанні антибіотиків в якості стимуляторів росту при вирощуванні бройлерів.

What to expect

Stability in farm income and adaptive properties are two key factors that have been linked to high resilience of poultry farms in Nigeria.  But what can poultry farmers do to support this cost-effectively by nutritional means to stay competitive and reduce the need of antibiotic growth promotors?

In this webinar Dr. Gwendolyn Jones will be looking at how novel nutritional concepts can support current efforts to increase the adaptive capacity of farms for resilience in Nigerian poultry production. This includes adaptation strategies of poultry farmers to rising temperatures in Africa.

The adoption of existing and new technologies for adapting to climate change and variability is a high priority for many ecological regions in Nigeria. Adaptive capacity is the ability of individuals and communities to adjust to changes, to take advantage of opportunities or to cope with the consequences.

The adaptive capacity of poultry farms starts in the bird. Find out how improving the adaptive capacity of the bird by nutritional means can lead to more stable incomes, maintain higher productivity for longer in laying hens and reduce the need for antibiotic growth promotors in broiler and egg production.

Egg production – Resilience for laying persistence

In egg production longer laying cycles can help to cut costs, so they are a promising solution in a tough economic climate. Plus, they can reduce the environmental impact of egg production. Therefore, there is an increasing focus on improving laying persistence and egg quality at the end of the laying cycle. However, due to increasingly intensive metabolism for egg formation, laying hens are more susceptible to diseases, which requires a shift in breeding and nutrition towards greater resilience of birds to improve laying persistence for longer laying cycles.

There is a fast decline in egg production after the hens reach 480 d of age leading to reduced commercial value of laying hens. Understanding the mechanisms of the deterioration of the laying performance can help to slow down the process. The ovary and the liver are key organs involved in egg production of the laying hen, which is why knowing how to support them effectively by nutritional means can make a difference to laying persistence.

Oxidative stress in aging organs

Ovarian aging is one of the highest risk factors that lead to the decline of ovarian functions and hence a reduction in egg production. Studies have shown that oxidative stress plays a driving role in ovarian aging. The antioxidant status of the ovary decreases with age (Figure 2) as a result of a reduction in antioxidant enzymes and antioxidants in the hen’s own defense mechanisms. Oxidative stress is initiated by the gradual accumulation of reactive oxygen species (ROS) in the ovary and a reduction of the antioxidative capacity during the aging process. This will be exacerbated through stressors, such as heat, mycotoxins, endotoxins and others, which increase the production of ROS in the hen on a cellular level. A growing body of evidence suggests that oxidative stress is involved in most of commercially relevant stresses in poultry production. Oxidative stress is defined as an imbalance between production of ROS and their elimination by protective mechanisms. This imbalance leads to damage of important biomolecules and cells, with potential impact on the whole organism. It can also lead to inflammatory responses which can affect energy efficiency of the laying hen.

Age-related changes in the antioxidative capacity of the hen’s liver, is an important factor that influences liver function. Studies have demonstrated that the total antioxidant capacity of the liver declines as the hen ages (Figure 2) and this has also been linked to a decrease in egg production and in the ability of yolk precursor formation.

Feeding for resilience in egg production

To extend the laying cycle of commercial flocks, long-term maintenance of organs involved in producing eggs is required. Feeding for antioxidative capacity in laying hens has been shown to retard the antioxidant decline of aging ovaries and can thus help to maintain functioning ovaries for longer. It is also known to maintain a healthy liver for longer. However, feeding to improve the adaptive capacity of birds to stressors helps to minimize stress reactions, such as oxidative stress, as well as inflammatory responses and reduced feed intake, which can further increase resilience in birds and reduce the potential for stressors to diminish the chances for producers to successfully extend the laying period. Animal resilience has been defined as “the capacity of the animal to be minimally affected by challenges or to rapidly return to the state pertained before exposure to a challenge.

The gut agility concept in Anco FIT Poultry was specifically developed to increase the capacity of the bird to adapt to challenges more efficiently and to reduces stress reactions that would otherwise reduce the hens performance and potential to sustain longer laying cycles. A trial carried out in a commercial laying hen flock in Brazil, demonstrates how Anco FIT Poultry improves the resilience of birds to stressors compared to birds on a control diet (Figure 3). The impact of stressors was smaller on egg production and birds recovered quicker from stressors leading to greater laying persistency and more eggs produced per hen over the trial period.
