The research purpose is to assess safety of broiler chicken meat when correcting pre-slaughter stress using feed supplement “PIK-Antistress”. In the conditions of the poultry farm, three groups of broiler chickens were formed: the control group, experimental groups 1 and 2. Broiler chicken meat of all groups met GOST 31470-2012 by veterinary and sanitary characteristics. There was a statistically significant increase in the fat and protein content in white meat of experimental groups 1 and 2 by 5.9 and 0.6 %, respectively, a decrease in moisture in red meat by 0.6 %; a decrease in fat and protein content by 2.2 and 1.4 %, an increase in moisture and ash content by 0.9 and 0.8 %, respectively. There was an increase in the content of zinc, manganese and copper, while the concentrations of ionized forms of metals were significantly lower than the maximum allowable levels. The concentration of lithium in the pectoralis major muscle statistically significantly increased by 50.0 %, in the pectoralis minor – by 33.6 %, in red meat by 104.2 %.
Poultry is poorly adapted to high temperature parameters of the environment, the greater the body weight and density of the poultry, the more pronounced the consequences of heat stress are. It is possible to avoid the negative effect of heat stress on the physiological parameters and health of poultry by using specific and non-specific drugs. The studies presented in the article were carried out according to generally accepted methods. As a result, it was found that under experimental conditions with artificially created heat stress for broiler chickens, the use according to the scheme: NSAIDs with the active ingredient acetylsalicylic acid and PRODACTIV®ACIDSE promotes the preservation of the main productive indicators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
