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.

The present invention relates to the technical field of breeding, in particular to a breeding method for Nubian goats; including dynamic management of grass and livestock and feeding management, wherein the dynamic management of grass and livestock is sown according to the ratio of Gramineae to beans at 3:7, and according to The seedlings are grazing according to the length of the seedlings; feeding management adopts different levels of feeding and feeding different feeds. The specific operations are: young goats are fed breast milk, soybean milk, sesame paste, and condensed milk; Feed for feeding; adult goats are fed 1‑1.3kg / day for each feed, fed 3 times a day, and feed 40‑55% of concentrate and 35‑45% of coarse feed by weight, and the balance is Nutrients; pregnant goats are fed with artificial feeding and fed with protein powder. The breeding method of the present invention improves the adaptability and production performance of Nubian sheep, and the lambing rate is increased by 6.9%. Improvement by 9.6%.

The invention relates to a method for cultivating new strains / species of Guizhou black goat meat. The method comprises the following steps: 1) Breeding Guizhou black goats, Nubian goats, and Karaha goats; 2) Obtaining the female parent of Nuhei hybrid F1 1. Kanu hybrid F1 male parent; 3) Obtain Kanu black F2 female parent; 4) Obtain Kanu black F3 male parent and female parent, and fine Kanu black F3 generation is cross-fixed. The present invention uses the BLUP method combined with conventional breeding methods, and through technical means such as synchronous estrus, artificial insemination, superovulation, embryo transfer, etc., finally cultivates Karaha goats, Nubian goats, and Guizhou black goats. 50%, 37.5%, and 12.5% ​​are new meat strains (species), which can fully combine the high meat yield of Kalaha goats, the moderate meat yield of Nubian goats, and the hybrids with strong milking ability Advantages and retention of Guizhou black goat's good meat quality, resistance to rough feeding, and strong stress resistance.

The invention discloses a breeding method for a Puan black goat line. The breeding method utilizes foundation Guizhou black nanny goats and Nubia billy goats to bi-cross, first-class first Nubia billy goat-black nanny goat hybrid generation nanny goats chosen as the female parent and first-class Guizhou black billy goats chosen as the male parent backcross, first-class backcrossed filial generation billy goats and first-class nanny goats are chosen to cross to be fixed, and therefore the Puan black goat line with more stable genes is bred. By introducing the excellent genes of the Nubia goats, such as big build, high reproduction rate and fast growth, the breeding method ensures that the bred Puan black goat line has the advantages of big build, fast early growth and development, high reproduction rate, high meat productivity and the like besides the characteristics, such as high adaptability, high disease resistance and black clothing hair, of the Guizhou black goats.

The invention discloses a method for breeding a goat strain for Nubian-Huai meat, which comprises the following steps of: (1) hybridizing Nubian goats serving as male parents and Henan Huai goats serving as female parents, and selecting and keeping excellent female goats from the born F1 generation to form a first-filial generation female goat flock; (2) hybridizing the first-filial generation female goat flock serving as female parents and the Nubian goats serving as male parents to obtain an F2 generation, and selecting and keeping excellent female goats from the F2 generation to form a second-filial generation female goat flock; (3) hybridizing the second-filial generation female goat flock serving as female parents and the Nubian goats serving as male parents to obtain an F3 generation, and selecting and keeping excellent female goats from the F3 generation; (4) mating the excellent female goats selected from the F3 generation and the excellent male goats of the F2 generation to produce a zero generation goat flock of the goat strain for the Nubian-Huai meat; and (5) crossing and fixing the zero generation goat flock of the goat strain for the Nubian-Huai meat to breed the goat strain for the Nubian-Huai meat. The bred goat strain for the Nubian-Huai meat has quick growth and development, reaches over 30 kilograms at six months, and has the advantages of increased physique, improved meat yield and high feed reward.

The invention relates to the technical field of goat breeding, in particular to a Nubia goat breeding method. The raising management and the pasture management are combined; male goats and female goats are subjected to nutrition regulation and control in different periods; aphrodisiac mating is used as assistance; the concrete processes are shown as follows: in three months before the mating, the male and female goats are fed in different houses; the pasture time every day is not less than 4h; in 1 month before the pasture, the male and female goats are fed in a mixed way; the daily ration quantity is increased; in one week before the mating, on the basis of the former management, premixed materials are fed in a supplementary way; in the mating period, the pasture time of the breeding goats is not less than 5h per day; aphrodisiac feed is fed for the male and female goats; milk, eggs, mixed concentrated feed and coarse fodder are matched for feeding; the female goats in the gestational period are fed in a quantity increasing way; in addition, the pasture time every day does not exceed 3h. The method provided by the invention has the advantages that the health growth and the nutrition requirements of the goats can be maintained; the fertilization success ratio and the lambing percentage can be improved; the goat breeding performance is further enhanced.
