How to do a good job of cow breeding
Cow breeding is very important for dairy farms. The reproductive rate of dairy cows directly affects the level of milk production and herd health status. Therefore, the breeder should do a good job in the reproductive management of dairy cows.
1. Formulate reasonable reproductive performance indicators
Total pregnancy rate, estrus exposure rate, 50 days postpartum participation rate, emotional pregnancy rate, empty return rate, 180 days postpartum pregnancy rate, annual reproductive rate, average number of days of registration, fetal spacing, young cattle 13 months old Rate and other breeding performance indicators are the basis for measuring the technical level of a pasture breeder and are also important indicators for analysis and inspection of breeding management.
2. Natural delivery, monitoring postpartum
Clean, dry, sunny, well-ventilated, non-thievely, spacious, cold and warm, non-irrelevant vehicles and personnel is strictly prohibited is a necessary condition for natural delivery. Timely and effective cow-feeding for cows that may have difficulty producing timely, timely monitoring and diagnosis and treatment of abnormal cows such as dystocia, placental retention, premature delivery, miscarriage, etc., is the basis for guaranteeing the second pregnancy of cows.
3. Rational use of hormones, application of pre-concurrent ovulation timing of sperm output technology
As the yield of dairy cows continues to increase, the incidence of diseases such as ovarian cysts, quiescence of the ovaries, and persistent luteal diseases increases year by year, making it impossible for the dairy cows to postpone estrus or estrus and miss the best breeding opportunities. The application of pre-concurrent ovulation timing insemination technology can effectively control the post-partum voluntary waiting period and increase the participation rate of dairy cows according to the demand of pastures. As long as the procedures are strictly followed and executed, certain results can be achieved.
4. Early pregnancy test, shorten the tire spacing
In addition to the application of blood tests and B-ultrasound techniques 28 days after mating, it is best to perform three pregnancy tests at 43 to 49 days after mating, 90 to 120 days after pregnancy, and 220 to 228 after pregnancy. , Flow (early) production of cattle, as soon as possible to take measures to reduce the number of cattle empty days to shorten the gap between the tires and reduce the cost of ranching.
5 strict implementation, standard operation
In daily work, the breeder must strictly implement the various operations of breeding operations, grasp the basic concept of dairy cow breeding and related professional knowledge, familiar with the breeding operation process, master the cow's estrus identification, artificial insemination, pregnancy diagnosis, estrus during the same period, and prevent infertility Symptoms and other techniques, regular internal training or transfer to other advanced large-scale ranch learning, so that their knowledge is applied to the production line.
6. Perfect file management
Establish a complete herd archives and related supporting facilities, conscientiously do a good job of record collection and management of raw technical data on dairy cow production, conduct regular statistical analysis of breeding data, and provide effective data for solving problems in production and formulating breeding plans. stand by.
7. Reasonable grouping and management of reserve cattle
Collect, sort and analyze data in a timely manner, and combine the measured yield, body condition scores and other data to formulate and adjust the herd distribution for pastures. Reserve cattle are the hope of pastures. Daily feeding management and group feeding are also very important. According to age, feed intake, and size, reasonable grouping can ensure the daily weight gain and the subsequent successful breeding work.
