Reproductive function of an organism of cows and rabbits at adding to ration of citrates of microelements

Abstract

The purpose. To determine influence of citrates of microelements gained by the methods of nano- technologies upon reproductive function of an organism of cows and rabbits. Methods. Physiological, zootechnical and statistical methods, and nano-technological substances. Results. Activating effect is fixed of citrate of Se (30 and 60 mkg), which was applied in a feed of cows in the first 2 months of lactation, on function of reproduction with decrease of amount of inseminations for 17,4 — 30,4% and service-period for 36,2 — 46,1%. Complex application of citrate of Se in combination with citrates of J, Co, Cr and Zn resulted in decrease of amount of inseminations for 18,2%, and service-period for 28,3 — 29%. Conclusions. Addition in feed compound of cows of citrate of Se in the first 2 months of lactation decreased amount of inseminations and service-period, preserving such action at combination of Se with citrates of J, Co and Zn. Addition in feed of rabbits of citrate of Cr and its combination with sulphate of Na increased resistance and reproductive function of their organism with increase of amount and masses of born rabbits.
