SU1711864A1 - Method for artificial insemination of ewes - Google Patents

Abstract

The invention relates to animal husbandry. The aim of the inventions is to increase the efficiency of sperm use. The needle introduces sperm through one of the five zones on the body of the animal — the area of the hungry mouth, on the lumpy, annual, perineum, through the wall of the upper vaginal fornix. The dose of sperm gets on the wide uterine ligaments and rolls into the funnel-shaped extension of the tube located in the pocket formed by the ovaries. The method allows 10–20 times lower doses of sperm to achieve an increase in sheep fertility by 10.7-25.4% compared with the viso-cervical method. 2 Il. 3 tab.

Description

The invention of live breeding and can be used in artificial insemination of sheep.

The aim of the invention is to increase the semen use rate.

FIG. 1 shows areas of close access to the internal genitals of a sheep: - the region of the hungry weaver, II - by the lumbar region, IU - the annual area, IV region of the perineum, Y - through the wall of the upper vaginal fornix;

FIG. 2 shows the scheme of sperm delivery to the implantation: 1 - syringe with sperm, 2 - broad uterine ligaments, 3 - funnel extensions of the episode, 4 - pockets, 5 - ovary, 6 - uterine horn, 7 - cervix, 8 - rectum , 9 - vertebrae, 10 - vagina.

Through a needle inserted, for example, through a year-long area, the dose of sperm gets on the wide uterine ligaments 2 and rolls into a funnel-shaped extension of the branch pipe 3 located in the pocket 4 formed by the aquatic bridging.

Example. Animals selected in the hunt, pen: they are pressed tightly to each other in the split. Choose the closest access to the internal genital organs, for example, through the annual area. At the point of injection, the skin on the body of a sheep or cow is treated with an alcohol pad. The point of puncture is determined by the midpoint of the straight line, supposedly drawn from the root of the tail to the macklock. The area of the vcol area on the body of the animal is 10 X 10 cm. The needle is inserted perpendicular to the skin of the annual area of the animal. A dose of sperm in 1 ml of 10-20 million sperms is pushed out of a syringe through a needle into the pelvic cavity of a sheep.

Animals are inseminated in connection with shortening the path of sperm advancement to the fertilization site 8-10 hours after you leave. no sex hunting.

The results of artificial insemination of sheep by the proposed method are shown in Table 1.

From tab. 1 shows that the fertilization of sheep after a single insemination of the W. hoot by the proposed method, when used in 1 ml and 10–20 times Less spermatozoa than the Viso-cervical method, was higher by 10.7-25.4%.

The results of artificial insemination of sheep by the proposed method in various hosts are presented in table. 2

From tab. 2, it can be seen that after a single artificial insemination of sheep with the proposed method with a dose of 1 ml (20 million sperm), fertilization ranged from 64.2% to 95.6%. After the same viso-cervical insemination (0.2 ml dose, 100 million sperm), fertility was 61.64%.,.

The results of the production experience are reflected in the table. 3

From tab. 3, it can be seen that after artificial insemination of sheep with diluted sperm using the proposed method, fertilization of sheep was 8% higher than after viso-cervical insemination.

The advantage of this method is that a reduction in sperm losses along the tract (vagina, cervix,

horn of the uterus); probabilities of death of sperm from toxins, lysines, and bacteria in the genital tube are excluded; the path of sperm in the genital tube to the place of fertilization is shortened and the energy potential of sperm is preserved due to this, which leads to the preservation of its fertilizing ability, to an increase in the percentage of fertility of sheep and cows, to an economical consumption of sperm of breeding rams; Artificial insemination of sheep and cows can be carried out in a split and there is no need to forcibly fix each animal in the machine, which, with known insemination methods, leads to stress factors and reduces fertility.

The formula was invented by the Method of artificial insemination of sheep, including the introduction of sperm into the internal genital organs of the female; This is done so that, in order to increase the utilization rate of sperm, it is introduced directly onto the wide uterine ligaments by puncturing the animal’s tissues with a syringe with a needle in one of the five zones: annual, lumbar, hungry mka, perineum, through the wall of the upper, vaginal fornix.
