Ensuring Optimum Mixability In Feed Manufacturing: Part 1 - Introduction

Feed Processing 11 May 2009

Chin Sou Fei Novus International Pte Ltd Singapore Introduction The daily ration of nutrients that an animal receives from a feed may vary from time to time due to a number of reasons. The sources of variation will probably cause variation in the day-to-day level of nutrition received by an individual animal. Certain nutrients are guaranteed to be present at minimum levels and regulatory officials will be concerned, if guarantees are not met. Certain ingredients may be toxic at very high levels. The nutrient variation in feeds is most likely to occur for the following reasons (Wilcox and Baldi…
