I. INTRODUCTIONThe inclusion of alternative ingredients such as rice bran, DDGs and sunflower meal in layer diets, to reduce feed cost, can result in higher phytate levels, potentially limiting availability of minerals, protein and energy, all of which are important to maintain egg production, eggshell strength and bone strength (Bello and Korver, 2019). Phytase enzymes are commonly used in the an ...

I. INTRODUCTIONPhytase is commonly used in broiler diets at a typical dose level of 1000 FTU/kg feed to increase the P availability from phytate and reduce the need for inorganic phosphate inclusion. Increasing the phytase dose above this level is expected to further reduce the need to add inorganic phosphate and further reduce P excretion. In addition, if a phytase can break down phytate quickly ...

Introduction: The use of fine ground diets improve technical performance parameters like average daily weight gain (ADG) and feed conversion ratio (FCR). However, the use of fine ground diets is a risk factor for the formation of gastric ulcers in swine, which have a negative effect on animal welfare. The objective of this study is to improve animal welfare by reducing stomach ulcers without negat ...

 - Let's talk about the current state of antibiotic-free production. Although it has been discussed for many years now, is it advancing fast (and effectively) enough?When considering antibiotic-free production, one must keep in mind that the overall goal should be to reduce the total amount of antibiotics used in life stock production. So, the combination of antibiotic growth promoters (AGP) ...
