1. Beef cattle. It is widely distributed and has the largest number of feedings. Usually during pregnancy.
280-290 days, only 1 child a year.
2. Dairy cows. It is widely distributed and has a lot of feeding. Usually the gestation period is about 280 days, and only one child can be born a year.
3. Zebu cattle. It is distributed in the tropics and is very small in number. Usually, the gestation period is about 270 days, and only one child can be born a year.
4. Buffalo. It is mainly distributed in Asia, and the number is very small. Usually the gestation period is 300-330 days, and only one child can be born a year.
5. Yak. It is mainly distributed in the Qinghai-Tibet Plateau.
The number is small. Usually the gestation period is 250-260 days, and only one child can be born a year.
6. Bison. It is mainly found in South and Southeast Asia.
The number is extremely small. Usually, the gestation period is about 275 days, and only one child can be born a year.
To sum up, basically cows can only give birth to 1 litter a year. Of course, if the cow is sick, or the feeding level is very low, resulting in miscarriage, incompatibility, etc., in these cases, the cow will not be able to give birth once a year.

Cattle usually give birth to 1 calf in 1 litter, and in rare cases 2-3 calves.
Precautions for cow gestation: The gestation period of cows is generally 275 days to 285 days, with an average of 283 days; Strengthen protective measures, carry out herd management and grazing of pregnant cows, and do not whip and violently expel them; Strengthen feeding management, balance the diet, diversify the feed, supplement vitamins in a timely manner, do not feed moldy feed, and do not use drugs indiscriminately.

Hello, a cow can usually only give birth to one calf in one litter. Because of the large size of the cow, if it is a multiple birth, it will directly cause the death of the cow. But there is also more than one calf.
-
First, the use of cows will be affected, and cows that can be used for 8 or 10 years may not be able to produce after one or two litters;
Second, the calves have poor physical fitness after birth, and practice shows that the physical fitness of calves with multiple calves in one litter is significantly worse than that of calves with a single calf, and they are very prone to illness and the weaning survival rate is not ideal;
The third is that the cow's lactation is not enough for the calf to eat, a cow (non-dairy cow) has enough milk for a calf to eat, but two calves eat at the same time is not enough, in this case, the calf is not only poor in physique, slow growth, and easy to form a stiff cow to affect the fattening after weaning.

In the case of a cow, a calf is usually born in one litter, and in this case, it is one litter, and if the calf is born, it can walk independently after a few minutes.

Judging empirically mainly by the abnormal swelling of the abdominal circumference, pay attention to the abdominal circumference of the cattle, 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 to give birth to two calves.

A cow can give birth to 6-8 calves in her lifetime.
The number of calves a cow can give birth to in her lifetime depends on a variety of factors, such as her reproductive age, reproductive health, diet and environment. Ideally, a healthy cow can give birth to about 6-8 calves during its reproductive years.
The fertile period for cows generally begins at 15 months and continues until they are more than 10 years old. In the early stages of production, the reproductive capacity of female Huixiang cattle is usually relatively high, and can give birth to 1-2 calves per year. However, as they age, their fertility and productivity gradually decline.
In addition, some diseases and environmental stressors may also affect the fertility of cows.
Therefore, farmers need to pay attention to the diet and health of the cows, and provide a suitable living environment and veterinary health care to ensure their health and fertility. With proper breeding management, the number of calves that a cow can give birth to in her lifetime can reach 6-8 or even more.
Precautions for cows when giving birth
Diet management: Cows need a nutritious diet during pregnancy and lactation, and farmers need to provide adequate feed and water, while being careful not to overfeed to avoid gaining weight and affecting productivity.
Arrange a suitable living environment: Cows need a quiet, clean and ventilated living environment during the breeding period to reduce the pressure of production and maintain their health.
Maintain health: Farmers need to regularly check the health of their cows, including protection against infectious diseases and parasites, timely disease and necessary veterinary care.
Pay attention to the production process: Cows need to provide a safe and clean farrowing room to ensure the safety and hygiene of mothers and newborn calves, and at the same time pay attention to whether there are abnormal situations in the production process, and deal with and respond in a timely manner.
Reasonable breeding plan: Farmers need to develop a matching plan according to factors such as cow production efficiency, reproductive ability and genetic advantage of antecedents, so as to improve the reproductive efficiency and genetic quality of cows.
As long as you have a pregnancy certificate from the hospital, you can go to the family planning office of the local community to apply for a birth permit.
