Effectiveness of phytobiotic use in feeding broiler chickens

It is known that phytobiotics in feeding animals and poultry are the most promising due to their availability and absence of unwanted side effects and a wide range of biological effects on the body. The aim of the work was to study the effectiveness of the phytobiotic additive on productivity and feed consumption in broiler chickens. The phytobiotic supplement under investigation is a phytogenic growth stimulator that contains a complex of natural antibacterial substances that increase feed consumption and increase growth, reduce feed conversion, enhance the production of pancreatin enzyme and the formation of positive intestinal microflora, and inhibit the growth of pathogenic bacteria. One-day-old broiler chickens of the “Cobb-500” cross were selected for the experiment. The scientific and economic experiment lasted 42 days. The experimental broiler chickens were fed a complete ration compound feed that provided the need for all nutrients. Experimental groups of broiler chickens additionally consumed a phytobiotic feed additive in different doses. It was found that with additional phytobiotic consumption, broiler chickens had a higher live weight in the 2nd group by 7.3 % (Р < 0.001), the 3rd by 23.5 % (Р < 0.001) and the 4th by 20.3 % (P < 0.001), relative to the control. It was recorded that under the action of the feed additive in broilers of the 4th group, the survival rate of the stock increases by 2.0 %, compared to the control analogues. In addition, when broiler chickens are fed with a phytobiotic feed additive, the average daily growth in the 3rd group increases by 23.9 % (Р < 0.01) and the 4th by 20.7 % (Р < 0.05), against control analogs. It was found that the absolute growth of broiler chickens that consumed the phytobiotic increased in the 2nd group by 8.7 % (Р < 0.001), the 3rd by 24.0 % (Р < 0.001) and the 4th by 20.7 % (P < 0.001), compared to the control group. Under the action of the phytobiotic supplement, the broiler chickens of the experimental groups had a decrease in feed consumption per 1 kg of growth in the 2nd group by 9.0 %, the 3rd by 12.1 % and the 4th by 11.6 %, compared to the control value.
