Problems solved by technology

[0003] The existing technology is mainly to use cows that calved in the previous year and dry milk in that year to carry out artificial insemination to produce P cows. This method of cows producing P cows every other year has a very low reproductive rate

Embodiment 1

[0068] In the pastoral areas of the Qinghai-Tibet Plateau, pregnant cows start grazing on pastures at 9 o’clock in the morning starting from December, and after returning to pasture at 7 o’clock in the evening, the cows are supplemented with 3kg of green hay and 0.25kg of cornmeal, and the cows are allowed to go free lick mineral lick brick;

[0069] The calf is allowed to suck colostrum 0.5 hours after birth, and the calf is mainly fed with colostrum for the first 7 days after birth, and the calf is immunized against paratyphoid at the age of 7 days. After the calf is born, it grazes with the mother, and the cow is not artificially milked, and all the milk is used for the calf. The postpartum cows were fed 0.25 kg of cornmeal after returning to pasture, and the cows were allowed to lick mineral bricks freely. After the calves reached one month old, the cows and calves were injected with anthrax vaccine, bovine Pasteurella disease inactivated vaccine and foot-and-mouth diseas...

Embodiment 2

[0079] In the pastoral areas of the Qinghai-Tibet Plateau, pregnant cows start grazing on pastures at 9 o’clock in the morning starting from December, and after returning to pasture at 7 o’clock in the evening, the cows are supplemented with 3kg of green hay and 0.25kg of highland barley noodles, and the cows are allowed to freely Lick Mineral Lick Brick.

[0080] One hour after the calf was born, the calf was allowed to suck the colostrum, and the calf was mainly fed with colostrum for the first 7 days after birth, and the calf was immunized against paratyphoid at the age of 7 days. After the calf is born, it grazes with the mother. The cow is not milked manually, and all the milk is used for the calf. Postpartum cows were fed 0.25 kg of highland barley noodles after returning to pasture, and the cows were allowed to lick mineral bricks freely. After the calves reached one month old, the cows and calves were injected with anthrax vaccine, bovine Pasteurella disease inactivat...

Embodiment 3

[0087] In the pastoral areas of the Qinghai-Tibet Plateau, pregnant cows start grazing on pastures at 9 o’clock in the morning from December, and after returning to pasture at 7 o’clock in the evening, the cows are supplemented with 4kg of green hay and 0.25kg of cornmeal, and the cows are allowed to freely lick mineral lick brick;

[0088] The calf is allowed to suck colostrum 0.5 hours after birth, and the calf is mainly fed with colostrum for the first 7 days after birth, and the calf is immunized against paratyphoid at the age of 7 days. After the calf is born, it grazes with the mother. The cow is not milked manually, and all the milk is used for the calf. Postpartum cows were fed 0.25 kg of cornmeal after returning to pasture, and the cows were allowed to lick mineral bricks freely.

Abstract

The invention provides a method for breeding cattle-yaks. The method includes the steps of conducting supplementary feeding on pregnant chauri, breeding newborn calves after the calves are born in a lactation and graze combined mode, breeding the postpartum chauri in a graze and supplementary breeding combined mode, conducting ingestion training on the calves 25-35 days after the calves are born, conducting ablactation on the calves 3 months after the calves are born, breeding the multiparity chauri conducting ablactation in a graze prolonging and supplementary feeding combined mode, and conducting artificial insemination on chauri starting oestrus. By means of the breeding method, the chauri can each give birth to one calf each year, the survival rate of the calves is increased, and the breeding rate of the cattle-yaks is increased.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a method for producing Pyak. Background technique [0002] Pian cattle are the offspring of common cattle and yaks through interspecific crossbreeding. They have obvious hybrid advantages, and have excellent milk and meat production capacity and service ability. Pyaks play an extremely important role in people's production and life: First, castrated male Pyaks not only have the same adaptability to the plateau climate and environment as yaks, but also have the advantages of being more docile and easy to control, so they are used in pastoral areas. P cattle are often used as pack cattle, and are used to plow land in semi-agricultural and semi-pastoral areas or agricultural areas; second, for milk, compared with yaks, the milk production of female P cows will double, and the milk production cycle Long, can better meet the increasing demand for milk for herdsmen or large...
