Evaluation of the "Selenvet" in broiler chickens effect on productivity and economic efficiency
This paper is contained data on evaluation of the «Selenvet» in broiler chickens effect on veterinary-sanitary examination of the meat. The «Selenvet » is based on selenium, vitamin E and vitamin B1. The «Selenvet» is used in cattle, calves, sheep and poultry to treat and prevent metabolic disease and disorders. The object of the research is broiler-chickens. In order to carry out this study two groups were formed - one control and one experimental group. The «Selenvet» was given with water to broiler chickens of experimental group two times a week apart. The dosage was 0,08 ml per bird. To evaluate veterinary-sanitary and safety parameters of the meat the organoleptical bacteriological and physicochemical analyses were carried out. Also there were performed veterinary and sanitary assessments of poultry meat. The organoleptic, physico-chemical and bacteriological parameters and safety of the experimental group meat are not inferior to the same parameters of the control group meat; the experimental group meat is a good quality. The study data of experimental group poultry performance is signify favorable effect on mean daily weight gain of the poultry. The «Selenvet» in poultry allow reducing poultry mortality, increasing safety and growth rate of broiler-chickens and elevating overall slaughter weight of the poultry. During the assessment of veterinary and sanitary indicators of carcasses of broiler chickens deviations in the group of experience were not revealed. The economic efficiency of the drug "Selenovit° - B" amounted to 4.55 rubles per 1 ruble of costs.
