Safety monitoring of broiler chicken meat when correcting pre-slaughter stress using feed supplement “PIK-Antistress”

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 %.
