A new tool has emerged for broiler chicken operations seeking new ways to optimize results while keeping aligned with a full range of the latest organic, raised without antibiotics (RWA) and conventional market opportunities, according to an announcement from Canadian Bio-Systems Inc. (CBS Inc.).
New research results presented at the recent Poultry Science Assn. annual meeting add to a growing body of science showing the unique potential offered by "yeast bioactives" — a new form of feed technology introduced by CBS Inc., the announcement said.
“We are very pleased with the results we are seeing with this new feed technology,” said Mike Edwards of Edwards Family Organics near Millbank, Ont., a family-run farm that includes the broiler chicken operation where the trial was conducted. “It’s a new tool that has become a valuable part of our overall production approach — in particular, helping us to lower our bacterial challenges and promote better gut health. We’re seeing less issues. We’re achieving significant improvements in growth performance. It’s exciting to have a tool like this come into the marketplace that is eligible for use in organic.”
Yeast bioactives are a yeast-based innovation designed for use as a feed supplement in diets for poultry, swine and ruminants, CBS Inc. said, adding that the technology features enzymatically hydrolyzed yeast carbohydrates that offer advantages over conventional yeast cell wall supplements (the enzymatic hydrolyzation process makes the yeast carbohydrates more soluble and, thus, more effective).
Yeast bioactives offer benefits as an enhanced yeast technology supporting an optimal environment for animal wellness, performance and related productivity, CBS Inc. poultry sales manager Paul Garvey said. It also offers benefits as a grain management technology that helps mitigate a number of potential threats that can undermine feed quality, animal performance, animal health and food safety.
“The poultry industry has the potential to continue as one of the most progressive and successful sectors in agriculture, but as it continues to diversify and evolve, there is a strong need for new options in the toolbox at the producer level, particularly for operations targeting reduction or replacement of antimicrobial use,” Garvey said. “The results we’re seeing with yeast bioactives on commercial poultry farms point to this as a very effective option to support highly productive and sustainable operations across all types of production.”
CBS Inc. explained that the trial involved a total of 16,320 newly hatched Ross 708 broiler chicks. The study was designed to evaluate the effects of dietary supplementation with a commercially available yeast bioactives product (Maxi-Nutrio) on the performance and health of broiler chickens raised under a commercial organic production system. A subsample of 360 birds was randomly selected and placed in 18 identical floor pens, with 20 birds per pen, for a 28-day feeding study.
The experimental pens, which provided 966 sq. cm per bird of floor space, were located within the barn and were fitted with individual feeders and waterers. Birds were randomly assigned to one of three dietary treatments with or without yeast bioactives supplementation: one without, one step-down dose and one full dose. Results showed clear growth performance advantages with yeast bioactives supplementation, with the most pronounced beneficial effects observed in the full-dose treatment (1 kg per metric ton), the company said.
