Description
Technical Field
The invention relates to the technical field of goat genetic breeding, in particular to a breeding method of a Nanjiang yellow sheep.
Background
Goats (academic: capra hircus), also known as summer goats and black goats, are one of the earliest domestic animals domesticated by humans. It is speculated that, in the new stoneware period more than 10000 years ago, humans have begun to tame the history of goats. The goats domesticated in the western asia mountain area are mostly considered by scholars to be carried along with the migratory hikers of the nomadic nationality to various places in africa, europe and asia. There is evidence that our country is also one of the earliest countries for domesticating goats. The domestic goats in each place should be individually and independently domesticated due to the limited range of original human activities. The goats are very widely distributed throughout the world, and even in areas where domestic animals are difficult to live, goats can still survive and reproduce as usual, and the distribution areas are inferior to dogs, so that the goats become one of the most widely distributed areas in various domestic animals.
The goat breeds in China have a plurality of excellent characters, such as high fertility, good meat quality, fine velvet quality, good quality and high yield, and have special production performances of board skin, lamb skin, fur, milk and the like. At present, the breeding of goats is rough, the quality of the goats is basically determined by adopting an eye pattern, no unified standard exists, and the excellent goats selected by different people have larger difference, so that the improvement of the production performance of the whole population is not facilitated.

The upper and lower limits of these smaller ranges may independently be included or excluded in the range.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although only preferred methods and materials are described herein, any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention. All documents mentioned in this specification are incorporated by reference for the purpose of disclosing and describing the methods and/or materials associated with the documents. In case of conflict with any incorporated document, the present specification will control.
It will be apparent to those skilled in the art that various modifications and variations can be made in the specific embodiments of the invention described herein without departing from the scope or spirit of the invention. Other embodiments will be apparent to those skilled in the art from consideration of the specification of the present invention. The specification and examples are exemplary only.
As used herein, the terms "comprising," "including," "having," "containing," and the like are intended to be inclusive and mean an inclusion, but not limited to.
The technical scheme of the invention is conventional in the field, and the reagents or raw materials are purchased from commercial sources or are disclosed.
Example 1
Taking the breeding of the Nanjiang yellow sheep variety in Nanjiang county of Sichuan province as an example, the Nanjiang yellow sheep variety features: the color of the quilt is mainly yellow brown, dark yellow and light yellow, the head, the ear, the neck, the shoulder and the neck are well combined, the back and the waist are flat, the chest is deep and wide, the limbs are thick and strong, the physique is high, and the body is in a barrel shape.
1. Primary selection and retention: the first selection was made within one week of birth of the lamb.
The selection criteria are: the pedigree file is clear, and records the number, sex and date of birth of the individual. The father, mother, father, mother father and mother are selected, the information of the father, mother father and mother is clear, the birth weight is more than or equal to 3.0kg, the lambing number is more than two lambs, and the reproductive organ is normal in development, free of diseases, free of monotestosterone, cryptorchy, free of ears, free of hair and limb defect of the lambs.
2. Selecting and reserving 2 months old: the weaning day age of the lambs of the Nanjiang yellow sheep is 60d, the lambs of the breeding group are weaned by 60-70 days, and the weight, the height, the body length and the chest circumference of the lambs are measured. Body length: the linear distance from the chest to the rear end of the ischial tuberosity of the tested sheep was measured with the scale only when the firm flat ground end was standing. High: the vertical distance from the highest point of the shoulder blade to the ground when the tested sheep is standing on a solid flat ground is measured with a ruler. And (3) surrounding the pipe: the horizontal perimeter of the narrowest part of the left forelimb tube circumference of the tested sheep is measured by a tape only when the solid flat ground end stands up. Chest circumference: the length of the tested sheep, which is wound around the chest by the rear end of the shoulder blade for one week only when the solid flat ground is standing, is measured by a tape.
And (5) carrying out comparison analysis by using a regression coefficient unified kernel of 60 d. The tube circumference is more than or equal to 7cm, the body length is more than or equal to 49cm, the body height is more than or equal to 47cm, the daily gain of 0-2 months is more than or equal to 200g, the weight reaches 12.5kg, and the weight of the sheep meets the body shape characteristics of the Nanjiang yellow sheep.
3. Age 6 months, age, adult: the method is the most important stage of seed selection, can be used for grading according to the measured results, takes the weight index as the main evaluation basis, and refers to the body size index (adult sheep refers to the ram aged 2.5 or the ewe aged 2).
