What are the ways to improve the reproductive rate of dairy cows?
The dairy cow is a type of cattle whose main product is milk. Its farming area in our country is very large, and when farmers raise dairy cows, they all think about how to increase their milk production. In fact, the reproductive rate of dairy cows is also something we need to pay attention to, as it has a great impact on the sustainable development of the dairy herd. So how should we improve the reproductive rate of dairy cows when raising them? Let's take a look together below!
1. Improve nutrition
When raising dairy cows, insufficient or excessive nutrition may both lead to reproductive diseases in dairy cows. In the management before and after calving, we must ensure sufficient protein and energy, otherwise it may cause problems such as uterine inflammation, affecting ovarian function. In addition, we must ensure sufficient vitamin A, vitamin E and various trace elements. If these nutrients are lacking, it will cause the cow to have various adverse phenomena such as long-term absence of estrus and blocked estrus, and in severe cases lead to embryonic death. Therefore, we should reasonably control the amount added and the nutrition according to the growth stage of the dairy cow.
2. Feeding management
The period from 3 weeks before calving to 2 weeks after calving is the transition period of the cow. This period is the key time window for the production capacity and benefits of the herd. Cows in the transition period do not like to move, the vulva is loose and weak, in an open state, and various fluids will flow out. If not handled in time, it will easily lead to bacterial invasion, causing various production diseases such as uterine inflammation. So we should drive the cows to move for about two hours every day, in two sessions. We must do a good job in the sanitation of the cowshed, strengthen management, improve the physique of the dairy cows, and promote continued production. During calving, attention must be paid to doing a good job in disinfecting the herd and the calving room.
3. Identify estrus
When raising them, you must be able to grasp the estrus time of the dairy cows and carry out breeding. This is one of the main methods to improve the reproductive rate of dairy cows. If estrus is not discovered in time for breeding, then the conception rate will be reduced, directly affecting the breeding benefits. We can observe through various aspects of the dairy cow. When we find that the dairy cow's food intake decreases, production is insufficient, and then it is restless and chases cows in estrus, it means it is in estrus. And we can also observe the cow's vulva. If it is red and swollen, discharges mucus, and the labia are flattened, then it also means the cow is in estrus.
4. Timely insemination
If artificial insemination is carried out about three hours before ovulation of the dairy cow, it can effectively improve the conception rate of the dairy cow. First, we need to determine the cow in estrus, then check its follicles. When they are grape-sized and thin and soft, the insemination work can begin. During insemination, pay attention to whether the insemination gun can move forward smoothly. If it meets resistance, then stop in time to prevent harm to the cow's uterus. Then when the insemination gun enters the uterine horn, the insemination amount on both sides must be kept the same.
The above is a brief introduction to how to improve the reproductive rate of dairy cows. The reproductive rate of dairy cows can be said to also have a certain relationship with milk production, so everyone must pay more attention. That is all for today's introduction.
