NEWS 84 FEED & ADDITIVE MAGAZINE July 2024 While selected as feed for their availability, cost, and protein content, common raw feed ingredients can also negatively impact their own nutritional value and bioavailability. Gabriela Cardoso, Ph.D., Novus Poultry Solutions Manager for the Americas, will share how common feedstuffs like soybean meal and others can negatively impact poultry performance during X Seminario Internacional de Nutriciōn Avícol (X International Poultry Nutrition Seminar 2024), July 24-25 in Bogotá, Colombia. Hosted by the Colombian Association of Veterinary and Zootechnical Physicians (AMEVEA), the event includes the latest poultry research and trends. “Like the rest of the world, Colombia uses a lot of soybean meal in its chicken feed. It’s important for producers and nutritionists to understand how, without proper intervention or quality assurance, this common protein source can impact performance and, ultimately, the return on investment,” Cardoso says. In her presentation titled Immunogens vs. Antinutritional Factors in Poultry Feed, Cardoso will provide an overview of how immunogens cause inflammatory responses as well as information on the range of ingredients and circumstances that qualify as antinutritional factors (ANFs). “ANFs cover a broad spectrum of things. Mycotoxins are considered antinutritional, so are oxidized fats or oils, some fibers and soybean meal also have ANFs,” she continues. “The type of immunogens or ANFs you encounter change the nutritional intervention you use to combat them.” Read more>> Rumin8 announced positive top-line results from its three cattle trials of its investigational methane reducing feed additive. The cattle trials – lasting between 75-130 days and involving 92 head of cattle – recorded reductions of methane intensity of up to 86% and weight gains ranging 8.4 percent to 12.5 percent higher than control groups that were fed the same base ration. The trials were undertaken by independent universities in Australia, the United States and Brazil and funded by Rumin8. Analysis of three cattle trials showed that cattle produced less methane and gained more weight each day, on average, when fed Rumin8’s development stage methane reducing feed additive. “Weight gains are pivotal for the commercial adoption of methane reducing feed and water additives in the cattle industry. At the very least those weight gains have the potential to offset some of the cost of these additives, all while helping the planet,” said Rumin8 CEO, David Messina. “The main question from farmers when we have released methane reduction results has been: ’how will your product impact my productivity?’ These trials are helping us generate the data required to potentially answer these questions.” “While our number one focus remains on reducing methane production to address the critical climate risk that this gas presents, we are particularly interested in these initial weight gain figures, because productivity improvements are of high interest to farmers,” Messina continued.
