LIVER DEVELOPMENT IN BROILER CHICKENS DURING POSTEMBRYONIC ONTOGENESIS AFFECTED BY THE USE OF ARGUMISTIN

The article presents live weight indicators, as well as data on the mass and size of the liver of ROSS-308 broiler chickens against the background of the use of Argumistin in postembryonic ontogenesis. It was found that the increase in body weight of the experimental group exceeded the control group. The relative increase in body weight of the control chicks decreases in waves with drops by the sixteenth and forty-third days, whereas this indicator decreases relatively evenly in the experimental group. The liver weight of broiler chickens treated with Argumistin does not exceed the control group, but the relative increase is higher in the experimental group from the twenty-third to the fiftieth day. By the end of the study, the ratio of liver mass to body weight in the experimental group was lower than in the control group.
