Problems solved by technology

Aiming at the bottleneck problem of the imperfect artificial insemination technology system of southern goats, systematically researched the technical essentials of breeding sheep selection, estrus synchronization, pre-semen collection training of breeding rams, artificial semen collection, semen dilution, fresh semen insemination, etc., and invented this low-cost , The artificial insemination technology system with high conception rate is suitable for vigorous promotion and application in southern goats, and has great economic and social benefits

Embodiment 1

[0075] Technical standard for selection and retention of Nubian black goat rams (Procedures)

[0076] According to the breeding requirements and breeding goals, the selection and retention are carried out. In the seed selection, the male lambs for breeding are mainly selected from the breeding sheep farm and the core group, and the principle of more retention and selection is adopted, and the selection is carried out 3 times.

[0077] The first choice

[0078] 1.1 Genealogy

[0079] According to the pedigree of newborn lambs (father, mother, grandfather, grandmother, and descendants of parents), select lambs with excellent parents. These lambs have many genetic characteristics of their parents and have good genetic stability. The offspring are then selected by body shape and appearance.

[0080] 1.2 Physical appearance

[0081] From the first-born male lambs, choose lambs with large birth weight, strong feeding ability, healthy body, long waist and pure black coat color. S...

Abstract

The invention belongs to the technical field of goat breeding, and discloses an artificial breeding method for goats, which comprises the following steps: selecting breeding ewes and breeding rams; according to the pedigree information, the body shapes, appearances and production characteristics of the rams and the quality characteristics of the offspring sheep, the first rams in the field are selected for training before artificial semen collection; the estrus cycle of the breeding ewes is controlled and adjusted through hormones; semen collection is conducted on the breeding rams; and delivering the collected quantitative high-quality seminal fluid into the cervix of the ewe with the oestrus. Reserve ewes and nonpregnant ewes which are sexually mature, good in health condition, free of mastitis, strong in physique and all black in hair color are selected as breeding ewes. According to the artificial breeding method for goats, the utilization rate of high-quality rams can be increased, the conception rate is increased, and diseases are reduced; the feeding cost is reduced and the benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of goat breeding, in particular to a method for artificial breeding of goats. Background technique [0002] At present, artificial insemination of goats refers to the use of instruments to collect ram semen. After being examined and processed in vitro, a certain amount of semen is injected into a certain part of the reproductive tract of estrus ewes with instruments, and manual operation is used to replace a natural mating method breeding techniques. Artificial insemination can improve the utilization rate of breeding rams, speed up the improvement process of the flock, prevent the spread of diseases, and save the cost of raising a large number of breeding rams. However, the existing goat artificial breeding technology has high cost and low conception rate. [0003] To sum up, the problems and defects of the existing technology in the southern black goat are: the existing artificial breeding technology of ...
