Abstract

Aspects of prophylaxis of the latent endometritis of cows in dairy farms of the Khabarovsky Krai. N.F. KLYUCHNIKOVA, M.T. KLYUCHNIKOV (Far Eastern Research Institute of Agriculture, Khabarovsky Krai, Vostochnoe village).

In dairy farms of the region 2.334 cows were inspected during the wish period. 31.6 % of sick cows with latent endometritis were revealed. The impregnation of animals with this pathology is 42.2 % lower in comparison with healthy individuals. The more effective methods of diagnostics of cow latent endometritis before the insemination are developed empirically. The one-time injection of sodium selenite to the down-calving cows lowers the quantity of sick cow endometritis on 21.7 %.
