Abstract

The invention discloses a method for breeding a new Nubia and Funiu goat variety. Funiu white goat serving as a female parent and Nubia goat serving as a male parent are subjected to progressive hybridization, optimal combination, crossing fixation and reproduction and selective breeding to form the new Nubia and Funiu goat variety. In the method, the Nubia goat and Funiu white goat are hybridized; and because the Nubia goat has the characteristics of large body, rapid growth and development at an earlier stage, high feed conversion ratio and high milk production performance, and the Funiu white goat has the characteristics of high adaptability and the like, heterosis is obvious. The new Nubia and Funiu goat variety obtained by the breeding method has the appearance similar to the Nubia goat, has the advantages of large body, high lambing rate, rapid growth and development, high meat production performance and the like, and is suitable for fattening during barn feeding and captive breeding and developing the production of fat lambs.

Description

technical field [0001] The invention relates to a breeding method for a new strain of Nufu goat, belonging to the technical field of animal breeding. Background technique [0002] Funiu White Goat, formerly known as Xixia Big White Goat, belongs to the breed of both skin and meat. The central production area is in Neixiang County, Henan Province. Now it is mainly distributed in Neixiang, Xichuan, Xixia, Nanzhao, Zhenping counties and some cities and counties at the northern foot of Funiu Mountain. In the late 1990s, foreign breeds were introduced and crossed with barberry white goats, and the number of purebred barberry white goats decreased year by year. By the end of 2006, the number of Funiu white goats in the entire production area was only 689,000. From the perspective of breed quality, the past Funiu white goats had short necks, short bodies, short legs, small physiques, different sizes, and low production performance. After selection and breeding in recent years, t...
