? First, the body shape selection of breeding cows
For breeding cattle, the variety, purity and color have little influence, what is more important is the size of breeding cattle. First of all, the cow's body should be long. If the cow's body is long enough, the cow's body will grow, and the calf with long body will grow faster. Second, the cow's head should be relatively moderate and its body shape should be relatively thin. Third, cows have wider rear drive and lower dystocia rate.
Second, raise the mouth of the cow.
When selecting breeding cattle, it depends on whether there is foam in the mouth of the cow. If so, cows may have some diseases. It also depends on the teeth of the breeding cattle, which can be used to judge the age of the cattle.
Third, cultivate the fur of cattle.
If the cow's skin is dry and its hair is burnt, it is a sign of malnutrition. This kind of cattle may have some diseases and cannot be purchased.
Fourth, raise the cow legs.
If the breeding cattle have strong limbs, strong resistance, good physique, firmness and high meat yield, it is suitable for buying and breeding calves.
Five, the inspection of brucellosis in breeding cattle.
Breed cattle encounter brucellosis, which may lead to premature delivery, abortion and calf weakness. At the same time, the incidence of uterine inflammation will increase and even spread to other healthy cows. The most important thing is that it will cause infection to breeders.
? Six, choose the right weight of cattle.
? Although Daniel can breed quickly, the price is relatively high and uneconomical; When buying calves, the success rate of breeding is too high, and the waiting time for production and reproduction is longer. So choose a cow with the right weight.
