I. INTRODUCTION As we learn more about the negative impacts of calcium (Ca) on the availability of phosphorus (P) in broiler diets, it highlights how little we know about Ca requirements, digestibility of Ca in ingredients and optimal Ca to P ratios. The interactions through which Ca exerts some of its negative effects can be direct or through chelation’s with phytate and the latter having a ...

The Impact of Feed Pelleting on Enzyme ThermostabilityIn animal feed manufacturing, the process of pelleting is used to convert mash feed into compressed pellets. Pelleting provides several advantages, such as ease of handling, reduction of dust and waste and standard composition. The use of pelleted feed is also known to improve the feed conversion ratio (FCR) due to better digestibility and abso ...

The biggest challenges facing the poultry industry today include disease prevention, particularly in the absence of antibiotics, and optimum nutrition, especially with regards to being able to incorporate novel/local ingredients into the diet. Interestingly these two are linked as much of the disease pressure that challenges current poultry production is enteric in its nature. Since the presence o ...
