2021-01-22
1. Look at the ancestors of
breeding sheep. The quality of ancestors can be directly passed on to offspring. Therefore, the production performance (weight, meat yield, fertility, lactation, etc.) and appearance of the previous generations of sheep must be carefully examined when selecting breeds. Only good ancestors can have good offspring.
2. Look at the breeding sheep itself. Breed characteristics, body appearance, growth and development, production performance, etc. of breeding sheep will directly affect the next generation. Therefore, when we choose breeding sheep, we must select the best based on these characteristics, and select 1 breeding sheep. Generally, it takes many times. Identification (new birth, weaning, 6-month-old, 8-year-old, one-year-old and production, etc.) can be finalized.
3. Look at the offspring of breeding sheep. The quality of breeding sheep is ultimately determined by its offspring. Good offspring proves that the breeding sheep has strong heritability. Therefore, the quality of breeding sheep can be determined according to the characteristics of the offspring. As long as the offspring are not ideal, they cannot be reserved for breeding, especially rams.
