How can I make a cow produce more calves? Are there any tips?

Sex control frozen semen, find out. The success rate is 90% Dairy cows want cows to produce more calves, beef cattle want to let cows produce more male calves, for which people have researched and produced cattle sex control technology, cattle sex control is a biotechnology that makes cows reproduce the required sex offspring according to people's wishes through human intervention or operation, and this technology has played an important role in improving the economic benefits of cattle raising. Many cattle farmers see that cattle sex control technology must feel very difficult, in fact, for ordinary cattle farmers as long as artificial insemination technology can be carried out cattle gender control, now there are cattle sex control frozen sperm on the market, want to let cows produce more calves on the purchase of more bull sex control frozen semen, general cattle sex control frozen sperm can increase the probability of cows calves from 50% to 70%, and even some excellent cattle frozen sperm manufacturers produce sexual control frozen sperm can increase the probability of cows giving birth to male calves from 50% Increase to more than 90%.

Unfortunately, there is no way to make a cow produce more calves, because there are genetic issues involved, and it is not something that can be achieved with a few casual manipulations.

Milk and beef are very high, so people's enthusiasm for raising cattle is also very high. Cattle reproduce very slowly, and the pregnancy time of cattle is about 9 and a half months, so cattle can only give birth to one litter per year, and most of them are singletons, and only a few will give birth to twins. Therefore, most cows give birth to one calf per year, and if you want a cow to give birth to two calves a year, you can only find a way to have a cow give birth to twins.

Pull the cow back, and the cow didn't do anything again when it was tired. The people in the village asked me why I brought the cow back, and I told them about it, and several old people told me that the kneeling cow should not be sold, not killed, and raised. This kind of cattle is called the king of cattle in the older generation, and if it is a free-range cow, it can take a herd of cattle.

If you want to sell it, you have to buy a cow and raise it, any kind of cow can be, and the cattle pen can't be empty.

As far as the current level of beef cattle breeding in China is concerned, it is already very powerful to be able to make a calf a cow a year, and the profitability will be very high, so there is no need to deliberately pursue multiple calves in one litter! In many large-scale basic cow breeding bases, the empty rate of cows is very high, and they cannot be matched for breeding for a long time after giving birth, and they cannot guarantee one calf a year. The feeding management and nutritional standards of cows are still a difficult topic!

To be honest, I have lived in the countryside for so long, and I have really only seen the phenomenon of a cow giving birth to twins once, and 99% of them are one litter and one calf, and the phenomenon of twins is very difficult to see. In the past, farmers raised cattle for farming, so most of them raised one, and the cows would be sold even after giving birth. So most people don't go to great lengths to get a cow to have one more baby, so most of them are one litter, and one of the cows I have at home has given birth to several litters and has never given birth to twins.

For example, if you are familiar with the production process of these cows, in fact, in most cases, you will still produce a cow, so it is like giving birth to two calves, which is often referred to as the case of twins, because the situation of giving birth to two calves is not only related to the situation of these cows themselves, but also the rapid development of some science and technology, in fact, it is also possible to make cattle give birth to two calves a year through some work.

1. Breeding. This is the most natural way to do it, and all the cattle are bred from time to time to meet people's needs. If your cow has shown twins, then the next baby can be twins.

When these cattle are concentrated, they form a highly productive herd. After a certain amount of time of breeding, the reproductive function of this herd fluctuates, and a herd with multiple calves can be selected.

In the process of ideal cattle raising, this method has a long cycle, a large amount of tasks, and slow results, and it takes more than ten years or even decades to complete the breeding task.

2. Super ovulation. Everyone knows the number of calves born to the cow, which is mainly determined by the number of ovulations. Ovulation induction drugs can be used to stop overovulation in cows.

In the process of ideal cattle raising, this method has the results of no fluctuation in effect and high survival rate of calves.

3. Embryo transfer. I have participated in several cattle and sheep embryo transfers, which is more complicated, that is, the embryos are put into the uterine horns of the recipient cows, and a few embryos can be put into the calves.

This method is most volatile in the ideal cattle breeding process, although the majority of embryo transfers are aimed at breeding excellent breeds of cattle rather than calves. It's complicated to say, and it's difficult to do about a large number of cattle friends. Due to the need to stop the operation, a minimum of 3 to 5 professional veterinarians is required to complete the operation.

Be sure to choose a very strong cow, keep it in the process of raising it with proper movement, it is best to choose the method of artificial insemination when breeding, supplement the appropriate amount of concentrate feed after pregnancy, give them a good care after giving birth, and do not let them get sick.

The first thing is to choose some survival rate, and then to choose some more delicate cow breeds, and then to choose the right breeding time, and to give the cows more delicate feed, and to let these cows move more, and you can also give these cows more massage.

Summary. The decision of a cow to give birth to a bull calf is mainly determined by the bull's genes, not by the feed it eats. Cows can only provide half of the genes, while the other half is provided by bulls, so if all five cows in your family have male in a row, it means that the bulls used in your family are all xx genes.

What is the decision that a cow gives birth to a bull calf and a cow calf that my family has given birth to a male for five consecutive cows, and does it have anything to do with the reason and the material eaten?

The decision of a cow to give birth to a bull calf is mainly determined by the bull's genes, not by the feed it eats. Cows can only provide half of the genes, while the other half is provided by bulls or songs, so if your family has five consecutive rounds of rough cattle have been born males, it means that the bulls used in your family are all xx genes.

What does the xx gene mean.

The xx gene refers to the sex-determining gene carried by bulls, i.e., the X chromosome. The X chromosome is passed from the mother or ant cow to the bull, while the Y chromosome is passed from the bull to the calf. If a bull has the xx gene, then the calves it gives birth to will all be males, and if a bull has the xy gene, then the calves it produces may be male or female.

Can I choose to release frozen sperm to give birth to male and female?

As for the male and female of frozen sperm, it depends on what you want to achieve. If you know that you want a cow to give birth to a male calf, then you can use frozen sperm to achieve the goal.

Cows can generally only give birth to one calf per litter, and giving birth to two is a special case.

Ovulation induction drugs do not necessarily work, but only increase the probability.

On TV it was in vitro embryos.
