Feeding corn extract influence on the internal organs of meat chickens development

The purpose of research is to study the effect of feeding complete feed (CF) with 6.5 % corn extract and 6.2 % mixture of corn extract and perlite on productivity, ration conversion and development of internal organs of broiler chickens. From the fourth day of cultivation, three groups of 38 heads of young birds were formed according to the principle of pair-analogues. In accordance with the scheme of the experiment, the birds from the 1st (control) group were given complete feed (CF) without the inclusion of additives. Corn extract (CE) was added to the complete mixed feed for poultry of the 2nd (experimental) group in the amount of 6.5 % by weight of the feed. The diet for chickens of the 3rd group included 6.2 % of a mixture of corn extract and perlite (in a ratio of 3.42 : 1). Feeding 6.5 % corn extract resulted in a 1.8 % increase in heart mass; a significant decrease in liver weight by 12.7 % (p
