Boyarchuck S. The use of nutrients and performance of broiler chickens at different levels of metabolizable energy in the diet

Increased knowledge on how to use nutrients broiler chickens of different ages and determination of metabolizable energy in feed in various ways. Found that the most accurate way to determine the energy value of the major components of feed for broiler chickens are those that are based on data from physiological studies. Obtained new data on the positive impact of six-regulation metabolizable energy content of the feed (1- to 42-th day respectively for weeks - 1.26 MJ, 1.33, 1.35, 1.37, 1.40 and 1.44 MJ/100 g) on the growth of broiler chickens by increasing the digestibility of nutrients, nitrogen use efficiency, increased retention of calcium and phosphorus. For the first time demonstrated that feeding broiler chickens full-feed, which recipe was developed based on actual energy value of basic components, increases their meat productivity.
