The introduction of breeding sheep is a must see
The quality of the breeding sheep directly affects the quality of the breeding offspring. In order to continuously improve the flock's physique and productivity, we must carefully select sheep. Among them, the rams have the greatest impact on the entire flock. Therefore, when selecting them, they must be more stringent. A look at the ancestors said: "Good seedlings, good Guagua good scoop." Progenitor varieties of the pros and cons, will be directly passed on to future generations. Therefore, in the introduction of breeding sheep, the production performance of several previous generations of sheep, such as weight, meat production, fecundity, lactation, body type, appearance, etc. should be carefully examined. Only good ancestors can have good offspring. Secondly, the cultivar characteristics, growth and development status, and production performance of the seed breeding sheep will be directly transmitted to the next generation. Therefore, when choosing sheep, you must choose the best one based on these characteristics. Under normal circumstances, the selection of breeding sheep can only be determined after multiple identifications such as primary births, weaning, 6 months of age, 8 months of age, age, and production. Third, the quality of future generations of sheep breeding quality, ultimately depends on their future generations to determine. If the offspring is good, it means that the breeding sheep has good genetic performance. Therefore, according to the characteristics of future generations, it is necessary to determine the quality of the breeding sheep and whether it will be left for planting. As long as the offspring are not ideal, no matter how good the species is, it cannot be used as a breeding sheep, especially for breeding rams.
