Cows can also conceive twins, how do cows with twins give birth?

Many people wonder why the cow multicalf technique is not applied to the cattle breeding process. Here I can make it clear that the technique of multiple calves for cows is real, and it has been proposed for at least a few decades, and I have been exposed to this problem since I was in college. As for why it has not been applied to the process of large-scale cattle raising, this question will be talked about later, and I will first tell you about the technology of multiple calves in one litter.

The main purpose of multiple calves in a cow is to improve the reproductive rate of cattle and maximize the benefits of cattle raising. There are three main points in the technique of multi-calf in one litter.

1. Breeding. When these cattle are grouped together, a productive herd is formed.

After a certain period of breeding, the reproductive performance of this herd is stable, and a herd with multiple calves can be selected.

In the actual process of cattle raising, this method has a long cycle, a large workload, and a slow effect, and it takes more than ten years or even decades to complete the breeding work.

2. Super ovulation. Everyone knows that the number of calves a cow gives birth to is mainly determined by the number of ovulations. Ovulation induction drugs can be used to perform superovulation on cows.

In the actual cattle breeding process, this method has problems such as unstable effect and low survival rate of calves.

3. Embryo transfer. I have participated in several cattle and sheep embryo transfers, which is relatively simple, that is, put the embryos into the uterine horns of the recipient cow, and put in a few embryos to generally breed a few calves.

This method is most stable in real-world cattle breeding, but most embryo transfers are aimed at breeding good breeds of cattle rather than multiple calves. It's easier said than done, but it's more difficult for most cow lovers. Because surgery is required, a minimum of 3 to 5 professional veterinarians are required to complete the operation.

Why not apply the technique of having multiple calves in the process of raising cattle?

1. The technology is unstable and difficult to operate in the process of cattle raising.

2. The cost is high, taking embryo transfer as an example, the cost may be a calf**.

3. The most unrealistic point is that cows have difficult births.

The rate is extremely high. In the case of double calves, the rate of dystocia of cows should reach 60% to 70%, and in the case of three calves, the rate of dystocia of cows should reach more than 90%. The purpose of multiple calves in one litter is to increase the profit of cattle raising, if the big cow and the calf die because of dystocia, not only can not improve the profit of cattle raising, but even lose money.

Some people sell drugs on the Internet that cows have multiple calves in one litter, claiming that they can calve more after using it. For this reason, I also bought this kind of drug to study it, most of them are some traditional Chinese medicine ingredients, similar to the egg increase in the process of laying hens. However, it is much more expensive than increasing eggs, and it has almost no effect on cattle, so I hope you don't fall for it.

Seek a professional veterinarian, the veterinarian will make corresponding treatment according to the production of the cattle, and those who do not understand should not give birth blindly.

Successively produced. When the cow gives birth, it is similar to a human, and it comes out one by one.

1. Determine whether the cow is pregnant with twins.

Empirically judged mainly by the abnormal swelling of the abdominal circumference, pay attention to the abdominal circumference of the cow, generally as long as the abdominal circumference is larger than the abdominal circumference of the normal pregnant cattle, then it is possible to be twins, and the arm can be deep into the birth canal to touch the fetus to determine whether it is twins.

2. The cattle are very adaptable and can better adapt to the local climate, and the suitable temperature is 15-25 degrees Celsius.

Cows stop eating when they are full, but they can't stop regurgitating.

Cows are vegetarians and eat a wide range of foods, most fond of grass, and also like to eat some green plants (or fruits), such as water peanuts.

Sweet potato vine (seedling), corn (seedling), rice, wheat seedling sap, etc.

Summary. Cows that have produced twin genes will also inherit twins, and many cattle farmers will breed these high-yielding cows well, selling only bulls and not cows, so as to breed high-yield cow herds. In the end, there will be a situation where the cows often have twins once they give birth, and at this time they can only be red-eyed, because these cows want to buy and do not sell.

Cows that have produced twin genes will also inherit twins, and many cattle farmers will breed bracelets for these high-yielding cows, only selling bulls and not cows, so as to breed high-yield cow herds. In the end, there will be a situation where the cows will often have twins once they give birth, and at this time they can only be hungry, because these cows want to buy and do not sell them.

Genetics. Cows are only twins when they are bred like this.

Conditioning medicine, words.

It's not a matter of breeding, it's genetics, and it's best if you buy twins born to a cow with a female calf. Keep the seeds.
