Why caring about climate change is good for your business
by Sabria Regragui Mazili, EW Nutrition
The Glasgow Climate Pact reached at the COP26 summit this November sent a clear message to businesses across the globe: Put sustainability on top of your corporate agenda or risk losing out. But how can food and feed producers translate the knowledge that climate change is happening into good business decisions? What impact is it causing, and which actions can we take today?
Activities such as burning fossil fuels, livestock farming, and deforestation release carbon dioxides and other greenhouse gases (GHG) into the atmosphere. GHG trap the sun’s heat and cause average temperatures to rise.
Compared to the pre-industrial era, average temperatures are now 1.2° C warmer. That doesn’t sound like a lot. But the effects are disastrous and disproportionately so for people in low-income communities and developing countries.
Climate change is already causing sea level rises, threatening coastal regions, and ocean acidification, which disrupts global seafood supplies. Unprecedented losses in biodiversity are compromising food security and ecosystem services (such as pollination and irrigation). Biodiversity losses also expose us to zoonotic diseases – for example, the ongoing COVID-19 pandemic has zoonotic origins.
Due to climate change, the frequency and severity of extreme weather events are increasing. As countries in Europe and China experience historic rainfall and flooding, other parts of the world, such as Australia, the western US, and many African countries, face intense droughts. With further warming, Pacific islands will disappear under rising sea levels. And regions such as the Middle East will suffer from extreme heatwaves and see farmland turn into deserts.
How climate change affects agricultural businesses
While some crops and areas benefit from higher temperatures and changed weather patterns, on the whole, it is becoming more difficult to feed the world. Extreme weather events such as droughts, floods, hurricanes, heatwaves, and wildfires pose severe challenges for agricultural businesses.
Agricultural production costs are and will be increasing further because climate change effects entail water scarcity, raw material shortages, higher energy prices, and stiffer competition for land as certain areas become climatically unsuitable for production.
Feed and food crop yields and quality suffer both from torrential rain and flooding and heat waves and droughts. Researchers from the University of Minnesota have found that climate change is already reducing global rice yields by 0.3% and wheat yields by 0.9%on average each year. Another study showed that every 1° C increase in global mean temperature would, on average, reduce global yields of wheat by 6.0%, rice by 3.2%, maize by 7.4%, and soybean by 3.1%.
We also see increased problems with pests and diseases. Pests already destroy 40 % of global crop production each year. As temperatures rise, pests from fall armyworms to desert locusts expand into new territories. Due to warmer temperatures, disease vectors such as mosquitoes, flies, and ticks also proliferate and migrate, carrying new pathogens to previously unexposed livestock. Additionally, decreased forage quality, heat stress, and water shortages already compromise livestock immunity.
And let’s not forget that the wellbeing and safety of the workforce are directly affected by climate change effects such as extreme temperatures and reduced air quality. This is even more true for outdoor workers and the 143 million “climate migrants” we expect to see by 2050. Climate change has also triggered a significant cultural shift, especially in younger generations. The climate-conscious GenZ talent only wants to work for employers who genuinely commit to sustainability.
Let your business thrive despite climate change
Global warming must be limited to 1.5° C to avert the most devastating impacts. To achieve this, we have to cut greenhouse gas emissions in half by 2030. And by 2050, the world has to reach “net-zero” emissions, i.e., removing as many greenhouse gases from the atmosphere as we release into it.
Climate change regulations are becoming more stringent, especially for the energy, transport, and agricultural sectors. As UN High-level Climate Action Champion Nigel Topping puts it:
“If you haven’t got a net-zero target now, you’re looking like you don’t care about the next generation, and you’re not paying attention to regulations coming down the pipe. Your credit rating is at risk, and your ability to attract and keep talent is at risk.”
What can we do? Agriculture is unusual in that its contribution to anthropogenic climate change mostly comes from methane and nitrous oxide instead of carbon dioxide. Nitrous oxide emissions stem from soils, fertilizers, and manure, while ruminants and rice cultivation release methane.
Across these sectors, much more needs to be done at the policy level to incentivize sustainable husbandry, knowledge transfer, and targeted R&D. Still, wider adoption of existing best practices and technologies would help the global food and feed sectors to be more resilient and substantially reduce its GHG.
Spend time on a detailed review of your company’s climate impact. This will reveal opportunities for emission reductions and decarbonization, both in your direct operations and along the value chain. More energy-efficient compound feed production, for example, helps feed mills but also improves the carbon footprint of the final animal products. And in times of Agriculture 4.0, investing in digital technologies, platforms, and processes will be vital to identifying and capitalizing on new business opportunities for climate-conscious production.
No one bears the brunt of climate change quite as intensely as agribusinesses. Let’s champion sustainability for improved corporate reputation, stronger risk management, long-run cost savings, market access, and attracting and retaining qualified employees and customers.
How animal nutrition can contribute to sustainability
by Inge Heinzl, EW Nutrition
Nowadays, the whole world is talking about sustainability. Many efforts aim to maintain our world for future generations, creating a balance between our current needs and those of our children, grandchildren, and great-grandchildren. The right animal nutrition choices play a crucial role in achieving the challenging aim of sustainable animal production.
Sustainability – an old concept now set out in writing
The idea of sustainability is not new. Already the first humans lived sustainably, taking only as much as they needed and the environment could cope with, using all parts of the animals they killed. The German Hannss Carl von Carlowitz (1645-1714) coined the term sustainability in his oeuvre “Sylvicultura oeconomica” to counter a threatening raw material crisis. Wood was one of the most important raw materials. Besides heating, it was used for shipbuilding and mining. This was the reason that extensive areas in Europe were deforested and became deserted. Observing the impending disaster, von Carlowitz ” (1713) stated that only as many trees should be felled as can grow back through planned reforestation, sowing, and planting.
The Brundtland Report (1987), a document created by the World Commission on Environment and Development, is reckoned to be the starting signal for worldwide discussions about sustainability. In 2015, the result of a meeting of 193 members of the United Nations was the Agenda 2030 with 17 sustainable development goals for a “world we want” that should be achieved by 2030.
Sustainable Development Goals (SDG) of the Agenda 2030, fixed by the UN in 2015
How can the feed sector contribute to sustainability?
The animal nutrition industry’s sustainability efforts play into different SDGs, notably no. 2, zero hunger, no. 3, good health and well-being, no. 12, responsible consumption and production, no. 13, climate action, no. 14, life below water, and no. 15, life on land. In addition to the overarching goal of fostering higher animal welfare (cf. Keeling et al., 2019), the feed sector’s measures center on three areas:
Optimal use of feed resources, which includes optimizing feed conversion, preserving feed quality, and using alternative ingredients
Preserving the environment by reducing ammonia and methane emissions and energy requirements
Reducing antibiotics usage to maintain their efficacy for future generations
1. Make best use of available resources
One of the 17 points on the list of the United Nations is “responsible consumption and production”. For the feed industry, this means making the most out of available feed sources. Improvements in feed conversion, the maintenance of feed quality, and the use of alternative ingredients are all part of this.
Optimize FCR to utilize the available feed best
The feed conversion rate shows the amount of feed consumed in relation to the outputs produced, such as weight gain, eggs, or milk. The better or lower the feed conversion rate (FCR), the less feed you need to achieve your target, and the higher the yield. Products that improve feed conversion, therefore, can help to save resources.
Good feed conversion or an optimal utilization of nutrients depends on gut health. Only a healthy gut can digest the feed and absorb the nutrients adequately. Hence, products to improve feed conversion often do so by improving gut health.
Phytomolecules: proven to improve feed conversion
Herbs and their active components have been used in human and veterinary medicine for thousands of years to treat digestive tract diseases. Nowadays, products based on phytomolecules help improve feed conversion through their digestive, anti-inflammatory, and antimicrobial effects on the intestinal tract.
How do these three characteristics contribute to a better FCR?
Phytomolecules stimulate the secretion of digestive juices and the motility of the gut
Their antimicrobial effect supports a “healthy” balance in the microbiome, preventing damages of the gut wall by harmful microbes and, therefore, maintaining an optimal nutrient absorption
Their anti-inflammatory properties also contribute to good nutrient absorption and reduce endogenous nutrient loss
FCR improvements in broilers thanks to ACTIVO found in several studies
As phytomolecules are often volatile, EW Nutrition offers encapsulated phytomolecule-based products for the feed (ACTIVO product line). During episodes of elevated enteric challenge, e.g., weaning or following feed change, a liquid solution (ACTIVO LIQUID) can be applied via the waterline.
Enzymes help to make nutrients available
Some feed materials are hard to digest for certain animals. For example, pigs’ digestive systems do not have the enzymes required to break down non-starch polysaccharides (NSPs), such as cellulose, hemicellulose (ß-glucans and xylans), pectins or oligosaccharides. However, pig feed ingredients usually contain these substances.
Besides the non-usability of NSPs, the cage effect is a further problem. Cellulose and hemicellulose, water-insoluble NSPs, encage nutrients such as proteins or digestible carbohydrates. Encaged nutrients cannot be reached by the digestive enzymes and don’t become available to the animal.
Xylanases are available on the market to degrade structural substances in the feed and make them, as well as the nutrients they encaged, available for the organism.
Maintain the quality of your feed materials
Another possibility to save resources is the maintenance of feed quality. Bad weather conditions at harvest or incorrect storage can downgrade feed quality due to the development of molds and their mycotoxins or the oxidation of nutrients. Products mitigating the adverse effects of toxins, acidifiers that reduce microbial load, and antioxidants can help to keep your feed quality on a high level – or to re-establish it.
Mitigate the adverse effects of mycotoxins
Feed materials contaminated with mycotoxins harm animals in different manners and should not be used without further treatment. Mycotoxins are not visible – even if no molds are visible, mycotoxins might be present. Additionally, they are pH- and thermo-stable, meaning that mycotoxins produced in the raw materials on the field remain in the finished feed. As mycotoxins often do not cause apparent, specific symptoms but manifest in decreased performance, feed refusal or lower feed intake, and higher disease susceptibility, it is difficult to notice contamination.
Products such as SOLIS or MASTERSORB contain clay minerals (bentonite and montmorillonite) that adsorb the toxins. MASTERSORB GOLD and MASTERSORB FM also include toxin-adsorbing yeast cell walls and herbal substances to help protect the liver.
Feed spoilage through molds, yeasts, and mycotoxins wastes precious resources
Reduce microbes in the feed with acidifiers
Acidifiers based on organic acids counter harmful microbes in the feed in two ways. Most pathogenic bacteria are susceptible to low pH. The proliferation of, e.g., E. coli, Salmonella, and Clostridium perfringens is minimized at pH < 5 (cf. Fuller 1977). Acidic-tolerant beneficial bacteria such as Lactobacilli or Bifidobacterium, however, survive.
Other than antimicrobial activity, organic acids also cause a significant reduction in ammonia (Eriksen et al., 2014). This finding could be due to a reduction in the microbial deamination of amino acids, which would then be available for absorption, resulting in increased nitrogen digestibility and reduced ammonia excretion, as observed in monogastrics fed organic acids (Pearlin et al., 2020).
The acidifier product lines ACIDOMIX, FORMYCINE, and PRO-STABIL all help protect feed from contamination with pathogenic microorganisms.
Protect the feed’s nutrients from oxidation
The oxidation of nutrients in the feed decreases its nutritional value and, thereby, the value of the whole diet. Fat, proteins, fat-soluble vitamins, pigments, and other biologically active molecules, including sugars and phospholipids, can get oxidized. Metal ions and other pro-oxidative factors can affect the ingredients of the feed during mixing, storage, and feeding. The oxidation of fats and fat-soluble vitamins results in color changes or odors and – this is even more serious – in the production of harmful substances such as aldehydes and ketones. An oxidized feed can lead to oxidative stress in the animals, reduce their immunity, productivity, and livability.
To protect valuable ingredients, the timely addition of effective antioxidants such as STABILON is recommended.
Use alternatives to natural protein sources
Soybeans are an excellent source of protein in animal nutrition. During the last 50 years, soy production has increased from 27 million tons to 269 million tons, causing environmental degradation of forests and savannas (WWF, 2021). The use of alternative protein sources helps protect our environment.
Ruminants partly cover their protein requirements with the help of rumen bacteria. These bacteria can turn nitrogen from urea into bacterial protein, provided they receive enough energy available from carbohydrates. Thanks to its encapsulation, PROTE-N, a feed-grade urea-based nitrogen source, slowly releases nitrogen into the rumen, synchronized with the energy supply. PROTE-N affords producers a degree of independence from soybean protein without compromising nutritional quality.
Reducing soybeans in ruminant feeds helps to lower their environmental impact
2. Preserve the environment
Animal production generates gases such as ammonia and methane that negatively impact the environment. Measures to reduce these gases help to protect plants, animals, us, and our globe.
Reduce ammonia by improving protein digestion
Besides nitrogen oxides, ammonia is one of the primary sources of nitrogen pollution. Ammonia damages ecological systems through acidification and nutritional oversupply. Fast-growing plants that need high amounts of nitrogen or plants that tolerate low soil pH proliferate, whereas more susceptible plants disappear, decreasing biodiversity. According to Max-Planck-Gesellschaft (2017), reducing ammonia emissions by 50 % could prevent 250.000 deaths caused by fine dust worldwide per year.
Improved protein digestion in animals reduces their ammonia production. Decreasing the intestinal pH through using organic acid-based products such as ACIDOMIX or FORMYCINE is essential for the activation and correct functioning of the enzymes responsible for protein digestion.
Reduce methane, the second most abundant greenhouse gas
Together with CO2, N2O, and three fluorinated gases, methane belongs to the greenhouse gases listed in the Kyoto protocol. Being over 25 times more potent than carbon dioxide at trapping heat in the atmosphere, it dramatically affects the earth’s temperature and the climate system (United States Environmental Protection Agency). Methane is a final product of feed fermentation in the rumen and is produced by methanogenic bacteria. Ruminants can produce 250-500 L methane per day (Johnson & Johnson, 1995).
Reducing methane production in ruminants is a critical step towards climate protection. Herbal substances can change the microbiome, leading to improved protein and fiber degradation and reduced methane production (Ku-Vera et al., 2020). ACTIVO PREMIUM is a phytomolecules-based product for ruminants that helps reduce their methane emissions.
To preserve the environment, reducing energy needs is also an important topic. Using the surfactant SURF-ACE in the pelletizing process, feed mills can cut 10-15 % of their energy consumption or produce up to 10-15 % higher pellet output without increasing their energy consumption. When moisture is added together with the surfactant, the emulsion of the dietary fat and the added water leads to better general lubrication of the machinery and improved press throughput.
Feed mill efficiency is key to animal nutrition’s carbon footprint
3. Reduce antibiotic use in animal production to keep this tool effective
Point 3 on the UN’s Agenda 2030 is good health and well-being. For many years, antibiotics, a very effective weapon, have been used to fight bacterial diseases. However, the occurrence of resistance is increasing. One of the reasons is the inappropriate use of antibiotics. These substances are often used preventively or for viral diseases against which they are ineffective. Also, the use of antibiotics as growth promoters at low dosages in animal production strongly contributed to the development of antimicrobial resistance.
The feed sector has the tools to achieve more sustainability!
The animal nutrition industry provides many products to support animal producers in coping with their main challenges, including the shift to more sustainable production practices. Solutions exist to save feed resources, better protect the environment, and keep antibiotic tools effective. As an additional reward, implementing sustainability solutions leads to healthy animals with high performance. Let’s all help to preserve this planet for our next generations!
