Synergistic use of different feed additives may support producers’ antibiotic reduction programmes

Reducing antibiotic use in poultry production is an urgent objective shared by stakeholders around the world. Global health authorities’ warnings about the human health threat posed by antimicrobial resistance have led many governments to impose legislative bans on the use of antibiotics as growth promoters in livestock production. Additionally, retailers and consumers continue to call for more transparency in how their food is produced. Yet at the same time, producers are challenged to meet growing demand for protein while maintaining profitable operations.During the Poultry Science Association (PSA) Annual Meeting, 23-26 July, in San Antonio, Texas, USA, several Trouw Nutrition studies were presented, focusing on precision nutrition solutions in broilers’ diet formulation and evaluating the effects of copper and zinc hydroxychloride on broilers’ growth performance compared to inorganic sources. Two of the studies, presented by Trouw Nutrition researchers, shared how an integrated approach to poultry nutrition using synergistic blends of feed additives applied in drinking water and feed may support producers’ antibiotic reduction efforts. The key findings from these two Trouw Nutrition research presentations delivered during the PSA Annual Meeting follow: Applying organic acids in drinking water may support growth performance while reducing FCR, improving footpad quality and lowering mortality rates compared to an in-feed antibiotic Greg Page, Trouw Nutrition Agresearch Canada, presented findings from a validation study done at Colorado Quality Research, USA, comparing growth performance among broilers receiving a blend of free and buffered organic acids to birds receiving in-feed AGPs to coccidiosis-vaccinated birds. At the trial’s conclusion, the birds receiving organic acids applied in drinking water had body weights (2.97kg) similar to birds receiving in-feed antimicrobial growth promotors (AGPs) and numerically higher body weights compared to birds in the control group (2.92kg). In addition, birds receiving high levels of organic acids in drinking water had significantly lower cumulative feed conversion ratios (FCR) than birds in the control group and in-feed antibiotic group. Footpad quality was significantly improved in birds receiving organic acids in their drinking water compared to the birds receiving AGPs and the control group. Additionally, birds given organic acid-supplemented water had numerically lower mortality rates (4.4 percent on average) compared to birds receiving AGPs (7.72 percent). Including copper hydroxychloride and synergistic organic acids in different nutrient density diets may support performance and improved FCR without additional cost Lane Pineda, Trouw Nutrition R&D, presented trial findings from a validation study, comparing the health and performance effects of a combination of copper hydroxychloride and a synergistic blend of gut health improving feed additives in feed and in water to in-feed AGPs added in a standard and sub-optimal diet. Results indicated that regardless of a diet’s nutrient density, broilers receiving the combination of copper hydroxychloride and a synergistic blend of gut health improving feed additives by feed and water showed health and performance benefits comparable to broilers receiving in-feed AGPs. Feed intake was comparable across all groups, while average daily gain was numerically increased with the addition of a synergistic blend of gut health improving feed additives resulting in parallel body weight gain to that of broilers receiving in-feed AGPs. The addition of an additive to the sub-optimal diet may improve nutrient digestibility and allow broilers to grow at a similar rate as broilers fed with the standard diet. The FCR was lower for broilers fed the standard diets supplemented with feed additives compared to other treatments. From an economic perspective, the cost per kg gain was lowest for birds receiving the standard diet supplemented with synergistic blends of feed additives or AGPs compared to birds receiving the modified diet with or without the feed additive. Global validation effort supports local approaches to antibiotic-free production Trouw Nutrition conducts validation trials around the globe to validate the efficacy of their products in varying production environments, responding to differences, for example, in local diet compositions, climate conditions and management systems. Through relationships with leading universities, key opinion leaders and a network of research centres spanning five continents, researchers publish their findings in scientific journals and apply the insights locally to help producers and integrators tailor an approach unique to their antibiotic reduction programme goals. More than 60 validation studies will be conducted in 2018.

Less wheat, more oilseed on global market

The World Agricultural Supply and Demand Estimates (WASDE) report, published June 12, writes that the decrease in wheat supplies are caused by production declines in Russia, the EU, and Mexico and are not completely offset by higher projected production from India and the United States. Russia’s production is lowered by 3.5 million tons to 68.5 million on drier-than-normal conditions this spring in winter wheat areas and excessive wetness in spring wheat regions lowering plantings. Russia’s wheat production is projected down 19% from last year’s record 85.0 million tons.EU wheat production is reduced 1.0 million tons to 149.4 million on dry conditions this spring for winter wheat in Germany and Poland. India’s wheat production is raised 2.0 million tons to 97.0 million, based on record yields and supported by reports of higher procurement for the 2018/19 crop compared to last year. Projected global 2018/19 trade is lower, mainly on reduced Russian exportable supplies with a smaller crop. Russia’s exports are reduced 1.5 million tons to 35.0 million, but Russia still remains the world’s leading wheat exporter. Global imports are lowered, mainly on reduced imports for India as the government recently raised its wheat import tariff. Projected 2018/19 world consumption is 3.0 million tons lower, primarily on reduced feed usage for Russia and the EU. Global ending stocks are raised 1.8 million tons this month to 266.2 million but are still below last year’s record 272.4 million. Global oilseed production up The 2018/19 global oilseed supply and demand forecasts include higher production, exports, and stocks compared to last month. Higher global soybean production is partly offset by lower rapeseed and cottonseed. Soybean production is up 0.7 million tons to 355.2 million mainly on higher production for Brazil. A higher trend yield for the 2018/19 Brazil soybean crop reflects harvest and yield results for the 2017/18 crop, which is increased 2 million tons to 119 million. With higher production, soybean exports for Brazil are revised up for both the 2017/18 and 2018/19 marketing years. Ending stocks for Brazil are also increased with higher production and a lower crush estimate for 2016/17. Global 2018/19 soybean ending stocks are increased 0.3 million tons to 87.0 million with higher stocks for Brazil partly offset by lower stocks for the United States and Argentina. Stocks for Argentina are lowered mainly on a 2.0-million-ton reduction to the 2017/18 crop to 37 million. Other changes include lower EU rapeseed production which is reduced on lower yields for Germany and Poland, where crops experienced warm and dry weather conditions through key flowering stages.

Northeastern US: More climate effects on corn

Climate projections indicate more warming will occur in the Northeast than other sections of the United States, and that has implications for corn crops and dairy farms in the region by 2050. This is according to researchers from Penn State University in the US. The results were published this month in PLOS One.9 global climate models The research group analysed potential effects of climate change on corn growth and development at 3 major dairy locations in the Northeast. Using localised projected climate data from 9 global climate models, researchers judged future corn-growing conditions at Syracuse, New York; State College, Pennsylvania; and Landisville, Pennsylvania. They calculated the number and timing of expected extreme heat days and crop water-deficit periods. Effect on Lancaster County Depending on which climate scenario occurs, the researchers could see severe impacts on corn production in that major dairy area. Lancaster County for example is looking like it is going to experience more days with extreme temperature stress that will reduce corn yields. The analysis indicates that corn in the Northeast near the end of the 21st century will experience fewer spring and fall freezes, and a faster rate of growing-degree-day accumulation with a reduction in time required to reach maturity. This analysis suggests that management strategies such as shifting the planting dates based on last spring freeze and in some cases irrigation during the greatest water-deficit stages could partially offset the projected increase in heat and drought stress. Future research should focus on understanding the effects of global warming at local levels and determining adaptation strategies that meet local needs, such as those in Lancaster County.

Feed enzymes to grow fastest in poultry

The market for protease in feed enzymes is projected to be the fastest-growing during the forecast period. Protease help farmers save on feed costs, owing to which the use of protease can contribute significantly to the current efforts focused on reducing nitrogen emissions during livestock production. Hence, protease is an emerging type of feed enzymes, which has been gaining popularity in the recent years.Poultry sector dominates In 2016, the poultry segment accounted for the largest share in global feed enzymes market. It provides poultry birds with proteins, thereby increasing their growth rate; they also strengthen their immune system. The demand for poultry meat is higher than the demand for other meat products. This drives the poultry segment in the feed enzymes market. Microorganism segment Enzymes extracted from microorganisms are of great importance in the manufacturing of animal feed. Currently, the latest molecular techniques are used to discover microbial enzymes, which are used in the feed industry to improve feed quality. These reasons drive the microorganism segment in the feed enzymes market. Asia-Pacific is fastest growing The fastest-growing market for feed enzymes between 2017 and 2022 is projected to be Asia-Pacific. The largest producer in the region, China, continues to contribute to the region’s leading position, with substantial growth witnessed in India and Japan. Pork and poultry are widely consumed in the Asia-Pacific region. The demand for poultry is estimated to increase in India and China, due to the rise in the population, increase in purchasing power, and changes in consumer food preferences. This increase in demand for meat protein has triggered meat production in the region, where uptake of feed enzymes has increased and is expected to show a healthy growth.
