Can farmed buffaloes swim? How to improve the conception rate? How many babies are born a year?

Buffalo mostly inhabit primeval forests and marshes, live alone or in pairs or in small groups, and feed on aquatic plants at dawn and dusk. All buffaloes are endangered species. Can the farmed buffalo swim? How to improve the conception rate? How many babies are born a year? It is learned from the bovine data that the buffalo can swim, and the buffalo has a big belly, big lungs and a lot of inhalation, and it is easy to float in the water. coupled with front foot planing and hind legs pedal, it can also walk freely in the mud.

How many births a year do farmed buffaloes give birth to?

1. Buffaloes are polygamous and breed in the tropics during the rainy season, usually from October to November, when females give birth every two years. Buffalo has the longest pregnancy in the bovine family, about 300-340 days. The female is 1 year old and the male is 2 years old. The life expectancy of wild buffalo is 12 years.

two。 The lowland buffalo can reproduce throughout the year, with a gestation period of 275-315 days, one litter per fetus, weaning at 6-9 months, sexual maturity at 2-3 years, and a life span of 28-30 years.

3. The Mindu Luo buffalo will give birth to one child per birth, and the gestation period is 300 days. Each child is born at an interval of two years. The calves will be taken care of by the cows for 2-4 years before they can be independent. The average life expectancy is 20 years, with a maximum of 25 years.

How to improve the conception rate of buffalo?

1. Make breeding records and analyze the breeding law of each cow.

The estrus and duration, body function and calving interval of each cow are not consistent, so we need to pay attention to the breeding record, master the law of individual reproduction and do a good job of cattle breeding.

two。 Do a good job in estrus identification and strive to achieve timely mating

The performance of estrus of buffalo is not obvious, increasing the number of daily observation is the key to do a good job of estrus identification, external observation can not be less than 4 times per day, although there are more cattle in quiet estrus, but the cattle in estrus basically have "hanging line" situation. Only by observing the estrus well can we lay the foundation for timely insemination. From May to September, due to the hot weather and the increase of mosquitoes and flies, it is more difficult to identify the estrus in the daytime, so the observation of estrus is mainly carried out at night. Mastering the period of estrus and timely insemination is the key to improve the conception rate of buffalo.

3. Pay attention to the breeding and breeding of buffalo at the peak of estrus.

Do a good job of breeding at the peak of estrus from 10 to April of the following year. These seven months are the peak period of estrus and the highest conception rate of buffalo. The average conception rate of these seven months is about 55%, and the highest is 62%. Therefore, special attention should be paid to estrus identification and timely breeding. Once the 7 months are missed, the annual reproduction rate will be greatly affected. From May to September, due to the hot weather and the increase of mosquitoes and flies, it is difficult to accurately observe whether cattle are in estrus and non-estrus, abnormal estrus (false estrus, delayed ovulation, anovulation). The average estrus conception rate is only about 32%.

4. Do a good job in the prevention and treatment of ovarian dysfunction and endometritis.

The treatment of ovarian dysfunction should be adjusted from two aspects of endocrine and nutritional metabolism, and the most commonly used drugs are PG, LHRH-A3 and so on. The prevention of endometritis is mainly based on prevention, which can be prevented from the following aspects: standardizing the hygiene of insemination operation, doing a good job of fetal protection and abortion prevention, strict delivery operation nursing, and paying attention to postpartum nursing.

5. Use the estrus synchronization technique in the off-season of estrus.

The estrus synchronization technique is convenient for breeders to grasp the estrus and ovulation of cattle, solves the difficult problem of estrus identification of buffalo, can basically achieve timely insemination, and significantly improves the conception rate of frozen semen.

6. The viability of frozen semen was detected before mating.

The freezing resistance of buffalo frozen semen is relatively low, and long-term low temperature has an effect on the viability of frozen semen. When there are conditions, the survival rate of the same batch of frozen semen is tested before mating, in order to rule out the use of frozen semen to damage the viability of frozen semen, which leads to the failure of breeding.
