How to choose frozen cows of high quality cows
The price of frozen sperm for excellent bulls is relatively high, and some dairy breeders in production tend to use lower-priced frozen semen in order to save money. This is a wasteful practice. According to the current price, the savings from a frozen sperm is no more than 200 yuan, but it may have lost a good offspring. The milk yield of a good bull offspring and a typical bull offspring may differ by 1 ton or even several tons, and the loss in a year is a few thousand dollars. Which is more cost-effective and clear. The bulls test the bulls and young bulls. The Bull City has been tested for offspring determination and has been rigorously analyzed to prove that it has a very improved bull effect. In other words, it has been known for its performance after the replacement, so the effect of improving the herd is guaranteed. The young Bull City was born out of the selection based only on the performance of its parents, but the performance of their offspring is not yet clear. Therefore, the effect of improving the herd is not absolutely guaranteed. The improved effect of the young bull is only to verify the bull's 1/1/ 4-1/3. It is advisable to use the verification bull as the main option and the young bull as the supplement, and at the same time pay attention to the pedigree of the bull and the improvement focus of the herd.
