Embodiment Construction

[0023] The following are embodiments of the invention:

[0024] 1. Breeding sheep

[0025] According to the selection method of Luoping Yellow Goat, the breeding sheep were selected, and 6 families were established, and 30 groups were formed. The generation interval of the breeding groups was more than 2.5 years, and the breeding method was selected according to the equal number of each family.

[0026] (1) Establishment of the basic sheep flock 30 breeding groups were established according to the family line, with 720 basic ewes and 30 breeding rams;

[0027] (2) Mating method Adopt multi-generation closed breeding and free mating method.

[0028] (3) The way of saving seeds Select and keep the same number of seeds in each family line to prevent gene loss as much as possible. One of the half-siblings of the offspring of each breeding ram is selected for seeding. One of the offspring of each ewe is selected to participate in breeding. When selecting and retaining rams and...

Abstract

The invention discloses a Luoping red goat purification and rejuvenation method; the method comprises the following steps of: goat selection, core-field breeding goat matching and grouping measures: goat selection: (1) type standard: the appearance meets the characteristics of the Luoping red goat, the goat is normal in growth and development, and the breeding goat or the sib doesn't include the Luoping red goat with the genetic defect; (2) initially selecting the breeding goat in four times through a comparison method; (3) once classifying and screening the 12-month goat according to the weight; (4) twice classifying and screening the adult goat according to the weight; (5) classifying and screening the female goat according to the annual output number of lambs; core-field breeding goat matching and grouping: keeping away from proximity of blood, grouping the female goat according to the proportion of 1:20, and breeding by a mating way controlled by a person; according to the breeding goat color and the propagation performance characteristics of the goat in goat selection, creating 3 families including 75 conservation population, wherein each family includes 25 male goats and 500 female goats, and the total number of the male goats is 75 and the total number of the female goats is 1500. According to the necessary management measures for feeding the goat flock, the purification and rejuvenation purpose of the Luoping red goat can be realized.

Description

technical field [0001] The invention relates to a method for purifying and rejuvenating Luoping yellow goats. Background technique [0002] The main body of Luoping Yellow Goat's coat is yellow, with light black backline and bellyline. There are two black stripes from the base of the two horns to the corner of the lip. The top of the head, the tip of the tail, the lower parts of the limbs, and the edges of the ears are black. It is pink in color and is a breed of goat with fine meat. However, due to the karst landform in Luoping County, the grazing area is small and scattered, which makes it impossible for herdsmen to move forward to large-scale breeding. At present, the breeding of yellow goats in Luoping area is all small-scale grazing. Therefore, the population of Luoping yellow goats is small and the breed is impure. Moreover, the epidemic prevention measures for scattered breeding cannot keep up, and the incidence of group epidemics is high. If no attention is paid t...
