Problems solved by technology

However, high reproductive rate and early growth rate are two opposite indicators in the biological field. The early growth rate with high reproductive rate is slow, and the reproductive rate with fast early growth rate must not be high.

Embodiment 1

[0033] Example 1: This example provides a method for cultivating a new breed of meat goat. A specialized meat breed adapted to the eastern Henan region is bred so that it is medium to large in size and has a certain degree of tolerance to humidity, heat and cold. Sex, good adaptability under grazing and barn feeding conditions, and can mate naturally; ewes are used as the female parent for meat, and rams are used as the terminal male parent. Concretely, the Boer goat selected by the present invention has the advantages of large physique, rapid growth and development, and high slaughter rate, but its disadvantage is that its reproductive performance is relatively poor, mainly manifested as late sexual maturity, strong seasonality of estrus, and inconspicuous performance, resulting in Its production performance is poor, which is not conducive to improving economic benefits.

Embodiment 2

[0050] Example 2: The method for cultivating new breeds of mutton sheep in this example is cultivated through three stages of progressive hybridization (1995-2013), cross-fixation (2014-2015) and group expansion breeding (2016-2018).

[0051] Breeding measures:

[0052] (1) Establish a breeding organization: Breeding work is a large systematic project. Establish a breeding leader for new varieties of mutton sheep in eastern Henan composed of leaders, experts and technicians who focus on animal husbandry, science and technology, relevant townships, and heads of large-scale sheep farms. The group is responsible for organizing the breeding of new breeds of mutton sheep in eastern Henan, responsible for registration of fine breeds, determination of production performance, formulation of selection standards, technical training, technical guidance and other breeding matters. Establish a complete breeding system to efficiently and strictly control the breeding of new varieties of Yud...

Embodiment 3

[0086] Example 3: Analysis of Heterogeneity of Bohuai Goat Breeds

[0087] Whole-genome resequencing was performed on the blood samples of 30 Yudong meat goats (Boer goat x Huai goat) and 5 Huai goats collected in Henan Province, combined with 127 other breeds published at home and abroad (including European goats) , African goats, Middle Eastern goats, Chinese southern goats, Chinese northern goats) goat genome data information, and analyze the genomic characteristics of the Bohuai goat breed.

[0088] After the samples are collected for sequencing, the data is processed, compared to the genome, and the SNP variation sites are detected for population structure analysis.

[0089] 1. Principal component analysis

[0090] Principal Component Analysis (PCA) is a statistical method. Through orthogonal transformation, a group of variables that may be correlated is converted into a group of linearly uncorrelated variables, and the converted group of variables is called the princip...

Abstract

The invention belongs to the technical field of new strain breeding methods of livestock and poultry, and particularly relates to a breeding method of a new East Henan meat goat variety. According to the method, the new meat goat strain is obtained by taking Huai goats in the East Henan area as female parents and Boer goats as male parents through three stages of hybridization innovation, cross-crossing fixation and group propagation. The new strain has the advantages of being good in meat type body shape, fast in growth and development, resistant to coarse feed, high in dressing percentage and net meat percentage, capable of achieving multiple birth and good in skin performance and has variety heterogeneity, powerful support is provided for development of the modern meat goat industry, and good economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of methods for cultivating new strains of livestock and poultry, and in particular relates to a method for cultivating new varieties of Yudong meat goats. Background technique [0002] A perfect breed breeding system is the prerequisite for the industrialization of mutton sheep, and together with forage resources, environmental conditions and traffic location constitute the necessary conditions for mutton sheep breeding. At present, the breeding system of mutton sheep breeds in China is mainly based on the cultivation of specialized breeds (strains) for meat, which conforms to the traditional breeding model. The development of the modern mutton sheep industry must have two essential conditions: high reproductive rate and fast early growth rate. However, a high reproductive rate and early growth rate are two opposite indicators in the biological field. A high reproductive rate has a slow early growth rate, w...
