Problems solved by technology

Due to the small number of female yaks calving and the large number of dead calves, the reproductive rate of yaks is extremely low, and the low reproductive rate seriously affects the development of the yak industry.
[0004] In order to increase the reproductive rate of yaks, the methods used in the prior art are mainly to increase the amount of feed for female yaks quantitatively for each meal when the winter is cold, and to increase the reproductive rate of yaks only by supplementing the feed. This method has very limited results.

Embodiment 1

[0061] In the pastoral areas of the Qinghai-Tibet Plateau, pregnant female yaks 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 female yaks are supplemented with 3kg of green hay and 0.25kg of cornmeal, and the female yaks are allowed to live freely. Lick minerals and lick bricks; 0.5 hours after the calf is born, the calf is allowed to suck the colostrum. 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 female yak is not milked manually, and all the milk is used for the calf. The postpartum female yaks were fed 0.25 kg of cornmeal after returning to pasture, and the female yaks were allowed to lick mineral bricks freely. After the calves reached one month old, the female yaks and calves were injected with anthrax vaccine, bovine Pasteurella...

Embodiment 2

[0070] In the pastoral areas of the Qinghai-Tibet Plateau, pregnant female yaks start grazing on pastures at 8 o'clock in the morning starting from December, and after returning to pasture at 8 o'clock in the evening, the female yaks are supplemented with 3kg of green hay and 0.25kg of highland barley noodles, and the female yaks are allowed to go free Lick Mineral Lick Brick.

[0071]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 female yak is not milked manually, and all the milk is used for the calf. Postpartum female yaks were fed 0.25 kg of highland barley noodles after returning to pasture, and the female yaks were allowed to lick mineral bricks freely. After the calves reached one month old, the female yaks and calves were injected with anth...

Embodiment 3

[0078] In the pastoral areas of the Qinghai-Tibet Plateau, pregnant female yaks 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 female yaks are supplemented with 4 kg of green hay and 0.25 kg of cornmeal, and the female yaks are allowed to live freely. lick mineral lick brick;

[0079] 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 female yak is not milked manually, and all the milk is used for the calf. The postpartum female yaks were fed 0.25 kg of cornmeal after returning to pasture, and the female yaks were allowed to lick mineral bricks freely.

Abstract

The invention provides a yak farming method. The method includes supplementing feed for pregnant female yaks; after calving, feeding the calves in a manner of combining lactating and grazing, and feeding the calved female yaks in a manner of combining grazing and feed supplementing; after 25 to 35 days after calving, training the calves to intake feed; after three months of calving, weaning the calves; feeding the female yaks stopping lactating in a manner of prolonging grazing and supplementing feed, and allowing the female yaks to breed after oestrus. By the aid of the method, a female yak calves once a year, the survive rate of calves can be increased, and the breeding rate of the female yaks is further increased.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a method for raising yaks. Background technique [0002] Yak is a unique cattle species in the alpine pastoral area of ​​the Qinghai-Tibet Plateau, a herbivorous ruminant livestock. The yak is a mammal that lives at the highest altitude in the world, and it is mainly produced in areas above 3,000 meters above sea level on the Qinghai-Tibet Plateau in China. The yak can adapt to the ecological conditions of the alpine and cold, is resistant to roughness and hard work, is good at walking steep and dangerous roads, snow-capped mountains and swamps, and can swim across the rapids of rivers and rivers. It is known as the "boat of the plateau". The whole body of a yak is a treasure, yak milk can be drunk, yak meat can be eaten, yak hide is a good material for leather, yak hair can be used to make clothes and tents, and yak dung can be burned as fuel. In addition, yaks can ...
