The use of organic minerals in the form of nanocompounds as a substitute for mineral inorganic salts is promising, but insufficiently studied. Therefore, the purpose of the search was to determine the influence of drinking sulfur citrate and sodium sulfate 14 days before insemination and up to 20th day of lactation on the reproductive capacity of rabbits and the preservation of the offspring up to 40th day of life. The research was carried out on rabbits of the second breed of Hyla breed in “Horlytsia”. Сontrol group were fed without restriction complete ration granular feed with free access to water. 1st experimental group were fed with the ration of the control group and during the day were watered with sulfur citrate, at the rate of 8 μg S/kg of body weight. II experimental group were fed with the ration of the control group and with water was given sodium sulfate in the amount of 40 mg S/kg of body weight. Additives to rabbits were watered 14 days before insemination and for up to 20 days of lactation. It was found that on the first day of life of young rabbits their number in the I and II experimental groups was respectively higher by 8.5 and 4.2% compared to the control. The number of young rabbits at 20 and 40 days of age in the I and II experimental groups was respectively higher by 10.4 and 4.4% and 14.0 and 4.6% compared to the control group. The weight of rabbits in the nest of the II experimental group at 1, 20 and 40 days of life was respectively higher by 2.8; 6.1 and 7.0%, which is based on the average mass of one rabbit for these periods and amounted to 1.1, respectively; 2.7 and 4.3% compared with animals in the control group. The average amount of milk produced by rabbits of I and II experimental groups was respectively higher by 10.2% and 6.6% per day and for 20 days of the lactation period compared to the control. The preservation of rabbits in the I and II experimental groups was respectively higher by 6.4 and 6.4% and 3.6 and 4.4% at 20 and 40 days of life of young rabbits compared to the control group. The results of the research indicate the possibility of additional use in the ration of rabbits of the addition of sulfur citrate in the amount of 8 μg S/kg of body weight to increase metabolism and reproductive capacity during periods of increased physiological load
