Murphy, Ph.D., is research coordinator, Alltech European Bioscience Centre in Dunboyne, Ireland.From the AuthorHomeOrganic trace minerals: Enhanced stability ensures efficacyThere are many forms of mineral complexes and chelates available for use in animal nutrition, all of which are generically referred to as organic trace minerals (OTMs).HomeMineral form's influence on enzyme supplementation responseIncreasingly, the agonistic and antagonistic effects of feed components have come under scrutiny, with choice of components gaining increasing importance in diet formulation. The possibility for negative interactions occurring between individual components within premixes and feeds is high, and while metal ions can act as enzyme inhibitors, little thought is given to the potential for mineral induced inhibition of enzyme activity.Antibiotic-Free MeatYeast cell wall derivatives improve broiler gut healthYeast cell wall derivatives can reduce antibiotics in poultry animal production, as well as functional feed components, such as MOS and MRF.HomeChoosing the best test for organic trace minerals in poultry feedOver the last two decades, organic minerals have been used as a partial replacement of trace mineral supply to improve certain areas of poultry productivity; this includes fertility in breeders, shell strength, and carcass and meat quality. Current research has identified future opportunities by replacing inorganic trace mineral sources with lower levels of the more available organic trace mineral forms, thereby minimizing the amount excreted and also optimizing trace mineral-associated performance traits.HomeChelates: clarity in the confusionDefining organic trace minerals can be a murky task but getting back to basics can make comparing bioavailabilities easier.Page 1 of 1
