SENERGY EFFECT OF ACTIVATED FEEDS AND CMA IN BROILER-CHICKENS REARING

Based on the experimental data the paper estimates the effect of activated feeds and cultured-milk additives (CMA) incorporated into the diet on broiler-chickens productivity. Many researchers were involved in the issues of cellulose degradation proposing physical, mechanical, chemical and microbiological techniques. At the present time the best techniques are recognized to be grain extrusion and expansion during which cell walls disrupt and nutritive substances are released. The present paper employs the idea of cellulose degradation in a mechanical way, i. e., super fine grinding followed by granulation of the raw material obtained. With activated feeds used in poultry feeding there is no need to introduce commercial enzymatic agents into feed mixtures which encourage higher digestibility of feed nutritive substances. The diet containing activated high enzymatic feeds (AHF) rather than grain feeds increases productive indexes of broiler-chickens. In the late rearing, AHF receiving poultry had the live weight by 61.1 g more than the control poultry. The joint use of AHJF and CMA in the diet provides a 382 g gain in mean live weight in broiler-chickens, 8.87 g daily weight gain, 16.7 % gain in total output. Herewith feed costs are minimal and make up 1.7 kg per 1 kg of live weight gain in broiler-chickens.
