Abstract
Purpose. Studying the effectiveness of using feed additive "Aciform" when included in the diet of broiler chickens. Materials and Methods. The objects of research were broiler chickens of Cobb-500 cross and feed additive "Aciform". The experiment was carried out in the conditions of the farm of Krest'yanskiy Dvor LLC (Volgograd region). Three groups (two experimental and control) were formed, 140 animals each. The poultry in the control group received feed that did not contain the studied feed additive. Norm for adding additive was 1 kg per 1 ton of feed in the 1st experimental group and 2 kg per 1 ton of feed in the 2nd experimental group. The duration of feeding is from 14 days to 42 days of age. During the experiment, the safety of poultry, the percentage of mortality and pecking, as well as the dynamics of live weight gain and the occurrence of possible side effects when using the feed additive were monitored using standard scientific research methods (zootechnical, mathematical) and certified laboratory equipment. Results. The use of new feed additive "Aciform" in feeding broiler chickens from 14 to 42 days of age at an input rate of 1 and 2 kg per 1 ton of feed had a positive effect on the increase in live weight of chickens. The chickens of experimental groups (1 and 2) exceeded poultry of control group in terms of the average daily gain in live weight by 1.0 and 2.9% (P≤0.05) for the entire experimental period, in terms of absolute increase on the 42nd day of growing – by 1.0 and 2.1%. The incidence of pecking in poultry of experimental groups (1 and 2) was 2.9 and 1.8%, and in the control group – 2.1%. In the groups of broiler chickens that received the test additive as part of the diet (1st and 2nd experimental), there were fewer dead poultry by 2.9 and 3.4%, and the survival rate was higher by 2.9 and 3.8% than in control group. Conclusion. The inclusion of new feed additive "Aciform" in the diet of broiler chickens had a positive effect on the safety, growth rate and productive qualities of the poultry.
