Embodiment 1

[0017] A kind of goat crossbreeding method, select the local black goat that is 2 years old, the standard weight is 42kg, the body height is 51cm, has a strong physique and has multiple lamb genes as the female parent, and the selected age is 2 years old, and the standard weight is 100kg , a Nubian goat with a height of 110cm, a strong physique, a strong breeding ability, and multiple lamb genes is used as the male parent. One month before artificial insemination, the female parent is fed with pasture and supplementary material A, mixed with 80kg of pasture grass and 15kg of supplementary material A Feed the female parent goat after uniformity; feed the male parent with forage grass and auxiliary material B, mix evenly with 80kg of forage grass and 15kg auxiliary material B, and then feed the female parent goat; after the multi-lamb gene detection of the female parent, artificial insemination is carried out to obtain the first generation of hybrid F1; backcross the obtained fir...

Embodiment 2

[0022] A kind of goat crossbreeding method, select the Ceheng local black goat that is 3 years old, the standard weight is 44kg, the body height is 56cm, has a strong physique and has multiple lamb genes as the female parent, and the age is 3 years old, and the standard weight is 115kg , a Nubian goat with a height of 120cm, a strong physique, a strong breeding ability, and multiple lamb genes is used as the male parent. One month before artificial insemination, the female parent is fed with pasture and supplementary material A, mixed with 80kg of pasture grass and 25kg of supplementary material A Feed the female parent goats after uniformity; feed the male parent with forage grass and supplementary material B, mix evenly with 80kg of pasture grass and 25kg of supplementary material B, and then feed the female parent goats; after multi-lamb gene detection for the female parent, artificial insemination is carried out to obtain the first generation of hybrid F1; backcross the obt...

Embodiment 3

[0027] A kind of goat crossbreeding method, select the Ceheng local black goat that is 3 years old, the standard weight is 46kg, the body height is 58cm, has a strong physique and has multiple lamb genes as the female parent, and the selected age is 3 years old, and the standard weight is 120kg , a Nubian goat with a height of 125cm, a strong physique, a strong breeding ability, and multiple lamb genes is used as the male parent. One month before artificial insemination, the female parent is fed with forage and auxiliary material A, mixed with 80kg of forage grass and 20kg of auxiliary material A Feed the female parent goat after uniformity; feed the male parent with forage grass and auxiliary material B, mix evenly with 80kg of forage grass and 20kg auxiliary material B, and then feed the female parent goat; after the female parent is tested for multiple lambs, artificial insemination is carried out to obtain the first generation of hybrid F1; backcross the obtained first-gene...

Abstract

The invention belongs to the technical field of livestock breeding, and particularly relates to a goat crossbreeding method. A Ceheng local black goat serves as a female parent, a Nubia goat serves as a male parent, artificial insemination is carried out after the female parent is subjected to prolificacy gene detection, and a first-filial generation F1 is obtained; the obtained first-filial generation F1 is subjected to backcrossing with the Nubia goat, and a second-filial generation F2; a high-quality male goat is selected from the second-filial generation F2 for transverse crossing fixation on the high-quality male goat to obtain a high-generation hybrid. According to the method, the Nubia goat serves as the male parent and the Ceheng local black goat serves as the female parent for hybridization; the obtained second-filial generation F2 has the advantages of being high in lambing rate, good in meat quality, quick in growth and development and good in meat type body size, and the meat productivity is improved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a goat hybrid breeding method. Background technique [0002] Guizhou Ceheng local black goat is an excellent local breed in the alpine mountainous area of ​​western Guizhou. It is suitable for grazing and feeding in the alpine mountainous area. It has the characteristics of good meat production, wide distribution and strong adaptability, but it is small in size and low in fecundity. In order to seek high-efficiency utilization of local black goat germplasm resources, the western region of Guizhou has successively introduced fine mutton sheep breeds such as Nanjiang yellow goat and Boer goat. The production performance of sheep is uneven, and the adaptability of different breeds of hybrid sheep to grazing in alpine mountainous areas is poor, and the weight gain rate, slaughter rate, and meat production performance of hybrid sheep deviate. [0003] Nubian goat is currentl...
