Increase of meat productivity and quality of broiler chickens meat when used ascorbic acid in mixed fodders
Unlike humans, a bird is able to synthesize vitamin C (ascorbic acid). However, the biosynthesis of this vitamin and its use by the body are not unchanged throughout life, therefore, the need for it also changes. The results of our own research to determine the effectiveness of differentiated use ascorbic acid in the composition of mixed fodders for broiler chickens are presented. It has been established that feeding chickens of the experimental group with ascorbic acid reduces feed costs by 3,2%. The energy supply of the breast fillet in the experimental group was at the level of the control index, the muscles of the leg over the control - by 2,4%. In the groups, the ratio in the muscles of the breast of water to the dry matter was 2,85: 1 and 2,83: 1, in the muscles of the leg was 2,90: 1 and 2,78: 1, respectively. Thus, the differentiated inclusion ascorbic acid in the diet of broiler chickens has a positive effect on the increase in productivity and improves the quality of meat with more rational use of feed.
