The effect of sorbent and probiotic on the productivity of broiler chickens

Relevance . As a result of the conducted zootechnical studies, the best combined effect of the probiotic and sorbent on the body and meat qualities of broiler chickens was established. The methodology. For the purpose of the experiment, groups of Ross 308 cross broiler chickens were selected: the control group I used the main diet in feeding, the experimental group II used probiotic “Prolam” and sorbent “Covelos-Sorb” in addition to the main diet, the experimental group III used probiotic “Prolam” in addition to the main diet, the experimental group IV used probiotic “Prolam” in addition to the main diet. the basic diet includes the “Covelos-Sorb” sorbent. Results. A positive effect of feeding the sorbent “Kovelos-Sorb” to broiler chickens as part of a complete feed has been established, contributing to an increase in their live weight by 3.4–8.8%, average daily live weight gain by 3.5–8.9%, livestock survival by 2.0–5.9%, and a decrease in feed costs per 1 kg of live weight gain by 3.2–8.0%. When feeding the sorbent and the probiotic “Prolam” together, net income increases by 24%, and the profitability level by 9.6%. The additional profit per head due to the combined use of the studied feed additives amounted to 13.73 rubles.
