Efficiency of phytobiotics in poultry farming

Abstract

The impact of phytobiotics of Brassica juncea, Linum usitatissimum, and Nigella sativa L. oils on the physiological and technological indexes of broiler chickens, as well as on the average weight of broiler chickens, and on the biological full-value of the resulting meat was studied. A positive effect was found on the average weight of broiler chickens by the time of slaughter, the rate of growth of the average weight of chickens in the group, the average weight of white meat, liver, and heart, and the concentration of vitamin D3 in the liver both when using only phytobiotics and in combination with an antibacterial drug. There were signs of enhanced antibacterial and antitoxic blood functions, as well as activation of cellular and humoral immune system components in the experimental groups. The results thus obtained might show the prospects for the use of phytobiotics based on Brassica juncea, Linum usitatissimum, and Nigella sativa L. oils to improve the physiological condition and productivity indicators of broiler chickens as an alternative or addition to antibiotic prophylaxis.
