ВПЛИВ ПРОБІОТИКА НА ПРОДУКТИВНІСТЬ КУРЧАТ-БРОЙЛЕРІВ

Abstract

<p><strong>The research objective. </strong>To research the effective action of probiotic (feed additive) ‘Probiol’ on the live weight, the growth, and slaughter traits of cross Ross-308 broiler chickens. <strong>Results.</strong> The live weight of broiler chickens fed with probiotic (feed additive) ‘Probiol’ was 2658.2 g (by 14.4% larger than control). Moreover, the survival rate of broiler chickens in experimental group increased by 4%. It was observed that average daily growth of broiler chickens from experimental group was higher by 14.7% and absolute growth was higher by 14.6% than in control group. It was observed that the feed consumption was 1.82 kg per 1 kg of chicken growth in control group and 1.68 in the experimental group (smaller by 9.6%). It was proved that usage of probiotic ‘Probiol’ caused the increasing of ante live weight by 15.5%, the undressed carcass by 15.6%, half-dressed carcass by 16.8%, and dressed carcass by 7.9 % compared to control group. The using of probiotic also increased the weight of pectoral muscles by 17.7% and femoral muscles by 13.0% of the chickens in experimental group; this was also facilitated the increasing of the weight of chicken glandular stomach by 35.0%. </p>
