EFFICIENCY OF ARTIFICIAL INSEMINATION IN RESPECT TO THE SCHEMES OF MALES SANITATION BEFORE GETTING SPERM

Abstract

The paper demonstrates results on artificial insemination with cool depreserved sperm, which is prepared according to Kharkovskaya technology in respect to sanitary treatment of sebum preputiale before receiving ejaculate. The authors suggest using concepts of true breeding efficiency and common one. True breeding efficiency assumes foal crop of female horses with ovulations whereas common breeding efficiency assumes foal crop of female horses with ovulations and not, i. e. all female horses for insemination. This approach evaluates true biological breeding efficiency of stored sperm production. The authors observed 23.69 % of horses with anovulatory cycle in the first group, 29.48 % of female horses in the second group, 21.64 % of horses in the third group and 28.46 % of horses in the forth group of total number of female horses for insemination. The publication shows that application of developed sanitary treatment of stud horses affected true foal crop of cool sperm insemination, which is 73.64 %, deiced sperm insemination makes 65.75 % whereas total foal crop is 56.65 and 45 %. Application of common sanitary treatment of stud horses affects true foal crop of cool sperm insemination which is 53.19 % and deiced sperm insemination is 38.04 %; total foal crop was 41.41 and 27.63 %. The authors recommend application of developed scheme of sanitary treatment of stud horse before getting sperm in order to increase efficiency of artificial insemination of female horses.
