How to improve the reproduction rate of dairy cows

Dairy cow is a kind of cow whose main product is milk. In China, the farming area is very large, farmers are thinking about how to improve its milk production when raising dairy cows. In fact, the reproduction rate of dairy cows also needs our attention, which has a great impact on the sustainable development of dairy cows. So how can we improve the reproduction rate of dairy cows when raising cows? Let's take a look at it with the editor.

1. Improve nutrition

When raising dairy cows, undernutrition or overnutrition may lead to reproductive diseases in dairy cows. In postpartum and postpartum management, we should ensure that there is sufficient protein and energy, otherwise it may cause uterine inflammation and other problems, resulting in ovarian function affected. In addition, we also need to ensure that vitamin a, vitamin E and various trace elements are adequate, if the lack of these nutrients, it will lead to a long period of non-estrus, estrus obstruction and other adverse phenomena, and in serious cases lead to embryo death. Therefore, we should reasonably control the addition and nutrition of ha according to the growth period of dairy cows.

2. Feeding and management

The perinatal period is from 3 weeks before delivery to 2 weeks after delivery. This period is a critical period for the production capacity and benefit of the herd. Perinatal cows do not like exercise, vaginal relaxation and weakness, in the open state, will flow out a variety of fluid. If it is not dealt with in a timely manner, it will easily lead to bacterial invasion and various production diseases such as uterine inflammation. So we have to drive the cows for about two hours every day, twice. It is necessary to do a good job in the hygiene of the barn, strengthen management, improve the physique of dairy cows, promote continued production, and pay attention to the disinfection of cattle herds and delivery rooms during delivery.

3. Identify estrus

In breeding, we must be able to grasp the time of oestrus and breed, which is one of the main methods to improve the reproduction rate of dairy cows. If estrus is not found in time for mating, it will reduce the conception rate and directly affect the efficiency of breeding. We can observe from all aspects of the cow, when it is found that the cow food intake is declining, the yield is insufficient, and then fidgeting, chasing the estrus cow represents the period of estrus. And you can also observe the cow's vulva, if red and swollen, mucus and flattened labia, then it also means that the cow is in estrus.

4. Timely insemination

If artificial insemination is carried out about three hours before ovulation, it can effectively improve the conception rate of dairy cows. First of all, we need to determine the estrus cow, and then check its follicles, when the grape size and thin soft, we can start insemination work. During insemination, we should pay attention to whether the insemination gun can move forward smoothly, and if it is blocked, it should be stopped in time to prevent damage to the cow's uterus. Then when the insemination gun is in the uterine corner, the amount of insemination on both sides must be the same.

The above is a brief introduction to how to improve the reproduction rate of dairy cows. The reproduction rate of dairy cows can be said to have a certain relationship with milk yield, so we must pay more attention to it. That's all for today's introduction.
