What does dairy farm breeding work mainly include?
Dairy cattle breeding technology is now very mature, and dairy cattle breeding work has become one of the most important processes in dairy production. If the dairy cattle breeding work is not done well, it will directly affect the later calving of the dairy cows. So what preparatory work and measures need to be done well? Below, the editor will explain it to everyone!
I. Breeding direction
Dairy cattle breeding should use the best improved breeds for breeding, ensure the yield and milk fat rate of each cow, and improve the udder tissue of dairy cows in later care to ensure their milk yield and milking efficiency, and raise the quality of milk as much as possible. This can ensure the healthy growth of calves and reduce the chance of insufficient nutrients.
II. Seed selection and matching
The annual breeding period is in October. In October, all bulls prepared for production are classified, the average level of 305-day milk yield of dairy cows is taken, and then the production performance of all bulls is tested and evaluated. Unqualified bulls or bulls with reproductive obstacles are screened out. The testing should evaluate all cattle on the farm in terms of appearance traits and other aspects, and finally a choice is made.
III. Replacement heifer rearing
Improved-breed cows are evaluated, and in October the most suitable cows for calving preparation are selected, then screened one by one, and finally the high-yielding population is selected as the final breeding cattle. Good bulls should be evaluated according to production performance and breedability. The rearing of replacement heifers also has a relatively large impact, as it can directly affect the quality of the traits of the next generation. Therefore, replacement heifers must be strictly tested. If they are not healthy cattle, they must be transferred to other breeding groups to be pending.
IV. Cattle registration records
Cattle registration records are the foundation to be done before breeding work. First, all cattle must be numbered and pedigreed, and then a series of records such as the birth date and growth and reproduction records of each one must be determined. Their sex must be especially recorded. The performance records of cattle must record the number of calvings and deliveries, the number of days of pregnancy, and the milk protein rate. All matters related to production performance must be recorded one by one, and finally statistics must be made to ensure that the growth information and death status of each cow are recorded clearly.
The above is the breeding work that a dairy farm needs to do. In breeding work, cattle registration records are a step we must do well. Many people ignore this step, causing problems in their subsequent breeding. I hope this article can help everyone. If you are interested, you can continue to follow the updates of Qinnong Network!
