Features of growth of replacement young meat chickens under the influence of the feed additive Salmocil F

Abstract

Normalization of the bacterial background of the gastrointestinal tract and the reaction of the environment largely contributes to the growth and development of poultry in accordance with the standard of cross. The addition of the prebiotic Salmocil F to the diet of replacement young poultry at the dose of 0,6 kg, 0,8 and 1,0 kg/t of compound feed allowed the poultry to grow to 18 weeks of age with a live weight of 1836,2 kg, 1915,4 and 1885,0 kg, respectively, which was higher than the control group by 0,7 %, 5,0 and 3,3 %, and the uniformity of the group by 8,0–9,0 %. The prebiotic Salmocil F contributed to the better development of the replacement young poultry such as muscularization of the pectoral muscle, its tone and physical shape. The prebiotic Salmocil F excluded the reason for the culling of poultry in the experimental group for toxicosis and intestinal intussusception, increasing the livability of livestock in the experimental group with the low dosage by 3,0 %, with medium and high by 4,0 %. The low dose of prebiotic in the diet of poultry of the 2nd experimental group in comparison with the 1st control group reduced expenditures of feed by 5,5 %, the average rate of input in the 3rd experimental group by 6,7 %, the high dose in the diet of chicks of the 4th experimental group by 6,1 %. The feed-conversion efficiency for receiving replacement young poultry per each 100 kg of feed fed in the group with the dosage of 0,6 kg in comparison with the control group was higher by 6,0 %, with the increase to 0,8 kg by 7,2 and with the addition of 1,0 kg/t of feed by 4,1 %, and in value terms by 5,4 %, 6,5 and 5,6 %, respectively. More optimal is the dosage of 0,8 kg of the prebiotic Salmocil F per 1 ton of compound feed.
