Dr. Christian Scheidemann, Country Business Manager Germany and Austria, shows that an innovative yeast derivative product (YANG, Lallemand Animal Nutrition) reduces the adverse effects of poor hygiene conditions on weaner piglets.
The study was conducted in South Korea in collaboration with Dankook University. The weaning of 160 piglets took place after 24 days, the animals were divided into two groups: the control group (n = 80) and the YANG group (n = 80). The second group piglets, after weaning, received the yeast derivative product over a period of six weeks with a two-phase feeding program. The results in the animals receiving the supplementation show:
- Improved Growth Performance: Both the final weight and average daily gains are significantly higher in the group that was supplemented with YANG.
- Increased digestibility of dry matter, possibly due to better intestinal efficiency.
- Modulation of inflammation of the intestinal mucosa, which are triggered by poor hygienic conditions. This was demonstrated by the decreased expression of proinflammatory cytokines (TNF-α, IL-6, TLR2 and INF-γ) in the gut of piglets in the YANG group compared to the control animals.
Bruno Bertaud du Chazaud, Product Manager for Yeast Derivatives, explains: "Our innovative yeast product YANG is a combination of different yeast strains with different properties that were carefully selected during product development for their immunomodulatory effect. In vitro experiments have demonstrated the synergistic effect of this combination of yeast fractions on the immune system, and the effect has subsequently been validated in various animal species. The new study shows that YANG has positive immunomodulatory effects even in piglets in difficult conditions, reducing mucosal inflammation and thereby saving energy used for better growth. "
