Problems solved by technology

[0002] Yunling black goat is the goat with the largest number and widest distribution among goats in Yunnan Province. It has many advantages such as resistance to rough feeding, drought and barrenness, strong adaptability and disease resistance. Due to harsh geographical and natural environment conditions, they are good at climbing high for food and have remarkable disease resistance; however, Yunling black goats are small in size, slow in growth, relatively low in reproduction rate, and poor in meat quality, so breed improvement is urgently needed
Boer goat (Boer Goat) is an excellent goat breed for meat. This breed is native to South Africa. It has the advantages of large size, fast growth, high slaughter rate, tender meat and good palatability; Nubian black goat has extremely Strong reproductive ability, good lactation, and more milk; but Boer goats and Nubian black goats are not well adapted to the harsh geographical and natural environment conditions in plateau areas such as Yunnan, so there will be many problems in direct introduction

Embodiment 1

[0031] 1) The Boer goat was used as the female parent and the Nubian black goat was used as the male parent to obtain the F1 hybrid goat;

[0032] 2) The F1 generation hybrid goat was used as the female parent, and the local Yunling black goat in Yunnan was used as the male parent, and the F2 generation hybrid goat was obtained as the first group;

[0033] 3) Reselect Boer goats, Nubian black goats and Yunling black goats, repeat steps (1) and (2), and get F2 hybrid goats again as the second group;

[0034] 4) Cross-fix the F2 generation hybrid goats between the first group and the second group, and screen out the non-black and deformed lambs to obtain the lambs with strong disease resistance, strong reproductive ability and meat quality suitable for growth in Yunnan. Good new breed crossbred goats.

Abstract

The invention discloses goat hybridization technology with a function of effectively improving disease-resistant and breeding capability and meat quality. The goat hybridization technology comprises the following steps: 1) hybridizing Boer goats and Nubia black goats by taking Boer goats as female parents and taking Nubia black goats as male parents to obtain F1-generation hybrid goats; 2)hybridizing F1-generation hybrid goats and Yunling black goats of Yunan Province to obtain F2-generation hybrid goats as a first group by taking F1-generation hybrid goats as female parents and taking Yunling black goats of Yunan Province as male parents; 3) selecting Boer goats, Nubia black goats and Yunling black goats again, repeating a step (1) and a step (2) and obtaining F2-generation hybrid goats again as a second group; 4) carrying out cross-fixing between the first group and the second group of F2-generation hybrid goats so as to obtain a new variety of hybrid goats with high disease resistance, breeding capabilities and good meat quality adapted to Yunan Province. The goat hybridization technology with the function of effectively improving disease-resistant and breeding capabilities and meat quality has the following beneficial effects: by adoption of hybridization technology, the new variety of hybrid goats has the extremely high disease-resistant and breeding capabilities and good meat quality so that the new variety of hybrid goats is suitable for being bred in Yunnan Province.
