Abstract

The article presents the results of studying the effect of a phytopreparation based on needles on the cellular and humoral immunity of broiler chickens of the ROSS 308 cross under vaccine stress. For the experiment, 25 groups of 1 heads were formed. Chickens of the control group were on the main diet. In the diet of the 2st experimental group, a phytopreparation based on needles was introduced with water, the 3nd and 14rd - with food. At the age of XNUMX days, the chickens were vaccinated against Newcastle disease (ND).
In broiler chickens vaccinated against ND and receiving the phytopreparation with feed, a more pronounced stimulating effect was noted, characterized by an increase in the number of T-lymphocytes by 1,3-1,8 times, cytotoxic T-lymphocytes - by 1,1-1,9 times , as well as the activity of cationic proteins - by 0,1-0,6 c.u. When drinking a complex of biologically active substances, only activation of intracellular antimicrobial peptides was observed, but in a longer period after vaccination.
