Embodiment 1

[0043] The breeding method of the cold-season female yak in the alpine region of the present embodiment includes:

[0044] (1) Introduce high-quality breeding male yaks in the warm season and graze breeding male yaks and female yaks at a ratio of 1:18. By the end of October, the old, weak, sick and disabled female yaks in the herd will be eliminated, and supplemented The number of healthy and capable breeding female yaks is the same as that of the eliminated ones to obtain an optimized herd.

[0045] (2) During the period from November to May of the following year, the optimized herds were raised in a semi-house feeding mode, and they were grazing naturally during the day, and the grazing time was from 8:00 to 19:00, and supplementary feeding was carried out in the greenhouse after harvesting; among them:

[0046] (21) The construction requirements for greenhouses include:

[0047] The size of the yak shed includes: the length of the shed is 15.8m, the width of the shed is 5....

Embodiment 2

[0060] The breeding method of the cold-season female yak in the alpine region of the present embodiment includes:

[0061] (1) Introduce high-quality breeding male yaks in the warm season and graze breeding male yaks and female yaks at a ratio of 1:22. By the end of October, the old, weak, sick and disabled female yaks in the herd will be eliminated and supplemented. The number of healthy and capable breeding female yaks is the same as that of the eliminated ones to obtain an optimized herd.

[0062] (2) During the period from November to May of the following year, the optimized herds were raised in a semi-house feeding mode, and they were grazing naturally during the day, and the grazing time was from 8:00 to 19:00, and supplementary feeding was carried out in the greenhouse after harvesting; among them:

[0063] (21) The construction requirements for greenhouses include:

[0064] The size of the yak shed includes: shed length 16.2m, shed width 6.2m, back wall height 2.2m, f...

Embodiment 3

[0075] The breeding method of the cold-season female yak in the alpine region of the present embodiment comprises:

[0076] (1) Introduce high-quality breeding male yaks in the warm season and graze breeding male yaks and female yaks at a ratio of 1:20. By the end of October, the old, weak, sick and disabled female yaks in the herd will be eliminated, and supplemented The number of healthy and capable breeding female yaks is the same as that of the eliminated ones to obtain an optimized herd.

[0077] (2) During the period from November to May of the following year, the optimized herds were raised in a semi-house feeding mode, and they were grazing naturally during the day, and the grazing time was from 8:00 to 19:00, and supplementary feeding was carried out in the greenhouse after harvesting; among them:

[0078] (21) The construction requirements for greenhouses include:

[0079] The size of the yak shed includes: the length of the shed is 16m, the width of the shed is 6m,...

Abstract

The invention discloses a breeding method of female yaks in cold season in the alpine region and belongs to the technical field of breeding of the yaks. In the method, the pregnancy rate of the femaleyaks is greatly increased, the female yaks are strong physically, and the miscarriage prevention rate, weight of born calves and production performances of milk yield are greatly increased by optimizing a herd population structure, adopting special feed for supplementary feeding in the cold season, providing environment-suitable worm sheds and adopting measures of expelling worms, invigorating stomach and the like; meanwhile, recovery of the female yaks can be sped up, fat loss of the yaks in the cold season is reduced, and the short-term fattening goal is achieved; a traditional yak breedingmode is reformed, high yield, high quality and efficient development of the animal husbandry are realized, turnover of the herd population is quickened, and production performance of the yaks is improved.

Description

technical field [0001] The invention relates to the technical field of yak breeding, in particular to a breeding method for cold-season female yaks in alpine regions. Background technique [0002] Yak is the original specialty domestic animal originating from the Qinghai-Tibet Plateau in my country. Due to its growth characteristics, it is known as the treasure of the plateau. Yaks have irreplaceable ecological, social and economic status in alpine regions. In high-altitude areas, the natural grass yield is low. Under the traditional grazing mode, the grassland is seriously degraded. In addition, due to the comprehensive influence of science and technology, the investment in scientific feeding and management of female yaks is insufficient. Poor, resulting in poor health of newly born calves and low milk production of lactating cows. [0003] Moreover, during the growth process of yaks, the nutrient reserves in the body are in a state of negative balance for a long time, so...
