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
The present invention relates to a kind of breeding method of exerting volt goat strain, belong to animal and cultivate technical field.
Background technology
The Fu Niubai goat, original name Xixia Da Bai goat belongs to skin and flesh dual-purpose type kind.The producing region, center shows the part cities and counties of counties such as mainly being distributed in interior township, Xichuan, Xixia, Nan Zhao, Zhenping and Funiu Shan Mountain northern foot in the Neixiang County, Henan Province.In the nineties later stage in last century, various places are introduced adventive and the inter breed crossing of Fu Niubai goat one after another, and purebred Fu Niubai goat quantity descends year by year.To the end of the year 2006, whole producing region Fu Niubai goat breeding stock has only 68.9 ten thousand.See that from variety and quality the Fu Niubai goat neck weak point in past, body weak point, short legs, physique are little, not of uniform size, productivity is not high.Through seed selection and breeding in recent years, bigger variation has taken place in the quality of Fu Niubai goat, and physique increase, body body, neck, leg length also rise appreciably, and regularity is higher, and meat performance is significantly improved.But because the huge numbers of families of peasant household raise scattered, can not adhere to the systematic selection seed selection for a long time, the kind premium properties is still uneven, and its meat performance has much room for improvement.
Summary of the invention
The purpose of this invention is to provide a kind of breeding method of exerting volt goat strain.
In order to realize above purpose, the technical scheme that the present invention adopted is: a kind of breeding method of exerting volt goat strain is a female parent with the Fu Niubai goat; With Nubia goat is that male parent is carried out grading up; Fix through preferred compositions and traversed by, expand numerous seed selection, cultivate and become to exert volt goat new lines.
Further, exert the breeding method of volt goat strain, may further comprise the steps:
(1) hybridize as Nubia goat of male parent and Fu Niubai goat as female parent, the F1 that gives birth to of institute in generation ram all eliminate, select the outstanding ewe of reservation, composition first-filial generation ewe crowd;
(2) being female parent with first-filial generation ewe crowd, is that male parent is hybridized with Nubia goat, F2 generation, from the F2 outstanding ewe of selecting and remain generation, form second filial generation ewe crowd;
(3) being female parent with second filial generation ewe crowd, is that male parent is hybridized with Nubia goat, F3 generation, from F3 select and remain generation outstanding ewe and ram, the two carries out mating afterwards, produces and exerts volt goat new lines zero flock of sheep from generation to generation;
(4) exert volt goat new lines zero from generation to generation flock of sheep carry out the traversed by of 3～4 generations and fix, expand numerous seed selection, obtain exerting volt goat new lines.
Wherein, the middle male parent of step (1) with the quantity ratio of female parent is: male parent: maternal=1: 20.
Adopting colony's subculture seed selection and molecular marker assisted selection method to carry out traversed by in the step (4) fixes.
The selection criteria of male parent Nubia goat is: short and small, and the Rome nose, bridge of the nose protuberance, ear is sagging greatly, neck length, trunk is shorter, and buttocks is short and tiltedly, four limbs are elongated, need not be acerous, short, glossy by capillary, more than the body weight 80kg, more than the height 80cm, more than the long 82cm of body.
The selection criteria of maternal Fu Niubai goat is: pure white by hair, the colour of skin is pink, and physique is solid, and structure is well-balanced, and physique is medium, and the body body is longer; Bone is solid, and is muscular, and head is delicate and pretty and wide at the top and narrow at the bottom, is triangular form, and the bridge of the nose is grand slightly, and ear is little and upright; Eyes have god greatly, and neck length is moderate, and eweneck is slightly narrow, and the ram neck is sturdy, and chest is darker, and rib is opened a business; Back of the body waist is straight, and each position of body body combines good, and middle body is slightly long, and belly enriches, and buttocks portion is oblique slightly, and four limbs are healthy and strong and rectify; Hard hooves, cured Huang of coffin or sallow, tail is short tapered, and breast is solid, and nipple is short and small; The weanling weight ewe is more than the 7.5kg, grows up more than the ewe body weight 35kg, more than the height 55cm, more than the long 60cm of body, more than the chest measurement 75cm.
Nubia goat originates in states such as Egypt, the Sudan and contiguous Ethiopia, Libya, Algeria of African northeast, in states such as Britain, the U.S., India, Eastern Europe and South Africa distribution is arranged all, has characteristics such as disposition docility, fertility are strong.Breeding method of the present invention utilizes Nubia goat kind and the hybridization of Fu Niubai goat; The characteristics that Nubia goat physique is big, early growth is grown soon, the price of deed is high, the performance of giving milk is good had both been utilized; Utilized the strong characteristics that wait of Fu Niubai goat adaptability again, hybrid vigour is obvious.That adopts that breeding method of the present invention obtains exerts volt goat new lines bodily form appearance near Nubia goat, has advantages such as physique is big, lambing percentage is high, grow fast, meat performance is good, and suitable drylot feeding and stable breeding are fattened, and are suitable for developing prime lamb production.
