Productive traits of chickens of the parent herd of broilers of the cross Ross 308 when using the drugs Emicidin and Apex

Abstract

Drugs with a wide spectrum of action, including natural growth stimulants and antioxidants, which could provide an increase in the natural resistance, livability and productivity of poultry of the parental herd and broiler chickens and did not adversely aff ect the quality of hatching eggs and poultry meat, are of considerable interest for industrial poultry farming. Such drugs include the antioxidant Emicidin and the natural growth stimulator of plant origin Apex. The drug Apex 3010 is used for poultry. The purpose of the work was to study the eff ect of the antioxidant Emicidin and the natural feed additive Apex 3010 on the productive traits of chickens of the parental herd under the conditions of industrial poultry housing technology. Comparative comprehensive studies of productivity, reproductive traits, morphological indicators of the quality of hatching eggs, the microstructure of the shell was carried out, the results of brooding of eggs of chickens of the parental broiler herd using the drugs Emicidin and Apex 3010 separately and in combination with each other were analyzed. It was found as a result of the conducted studies that the egg production of chickens for the initial laying hen in the 1st (Emicidin), 2nd (Apex 3010) and 3rd (Emicidin+Apex 3010) experimental groups was 2,6 % (p ≤ 0,05), 3,2 % (p ≤ 0,01) and 5,8 % (p ≤ 0,001), respectively, are higher than in the control group. The use of the drugs Emicidin and Apex 3010 both separately and in combination with each other had a positive infl uence on the quality of brooding eggs obtained from chickens of experimental groups at the end of the productive period at the age of 52 weeks. The highest production and economic indicators for the housing of chickens of the parental broiler herd were achieved in the 3rd experimental group with the complex use of the drugs Emicidin and Apex 3010. The diff erence in the prime-cost of 1 head the daily chicken in the 3rd experimental group and the control group was 1,52 rubles or 8,32 %.
