The article presents data on the application of different amounts of sodium citrate nanosulfur and sodium sulfate in the rabbit diet from 60 to 118 days of age and their effect on the biochemical parameters of blood plasma. The studies were carried out on young Hyla rabbits, divided into six groups of 6 animals in each. Animals of the first (І), second (ІІ), third (ІІІ) and the fourth (ІV) experimental groups were fed the diet of the control group and during one day nanosulfur citrate, calculated accordingly 2; 4; 8 and 12 mg S/kg body weight. Young females of the fifth (V) experimental group were fed the diet of the control group and set water with sodium sulfate (Na2SO4) in the amount of 40 mg S/kg body weight. The research lasted 68 days, including experimental period of 10 days, a test – 58 days. In the preparatory period – 60 days and in the experimental period – 91 and 118 days of life (31 and 58 days of delivery of supplements), samples of blood from the regional ear veins of the rabbits for biochemical studies were taken. As a result of the research, it was found that the administration of citrate nanosulfur in the amount of 8 mg S/kg body weight had a significant effect on the probable decrease in cholesterol and albumin increased (p<0.05) by 31 day of study compared to the control group. The administration of nanosulfur citrate in a larger amount of 12 mg S/kg body weight indicates a likely decrease in cholesterol during the experiment and a decrease in triacylglycerol at day 31 of the study compared with the control group. In the blood plasma of rabbits II and III, the level of albumin increased by 14.7 % and 13.5 % (p<0.05) by 31 days, as compared to the control group. In animals of other experimental groups, this indicator tended to increase. As a result of the conducted studies, optimal doses of citrate nanosulfur for young rabbits were determined.
