Problems solved by technology

However, at present, Tibetan sheep production in our province is still dominated by grazing. Due to the harsh natural environment of the Tibetan Plateau and the insufficient supply of grazing nutrients, ewes start breeding at the age of 1.5 and lambing at the age of 2. At the same time, primiparous ewe lambs are bred. The rate is only 72%, which seriously affects the reproductive performance of Tibetan sheep

Embodiment 1

[0036]This embodiment provides a whole-process high-efficiency cultivation method for early breeding of Tibetan sheep, including feeding management of lactating ewes, feeding management of lactating lambs, early mating ewe weaning selection, early mating ewe breeding, timely mating, and initial mating Feeding and management of ewes during pregnancy and lambing of primiparous ewes; specifically, the following steps are included:

[0037] Step 1. Feeding and management of lactating ewes

[0038] 1 month before lactation: The nutritional needs of lambs at this stage mainly come from breast milk. Lambs eat milk frequently. Improving the high lactation volume of ewes is the key. It is necessary to increase nutrient supply. , Supplement oat grass silage forage grass every day, greatly reduce grazing time, increase captive time, so that ewes have enough time to breastfeed; supplement feed oat grass silage forage 1.0-1.5kg a day in the early stage of lactation, daily supplement feedin...

Abstract

The invention relates to the field of livestock breeding, in particular to a whole-process efficient culture method for early breeding of Tibetan sheep. The method includes the steps of feeding and management of ewes in the suckling period, feeding and management of lambs in the suckling period, weaning selecting and remaining of earlier mating female lambs, breeding of the earlier mating female lambs, timely mating, feeding and management of ewes in the gestation period, and collecting lambs from primiparity ewes. By means of the comprehensive technical measures of breeding the earlier matingfemale lambs in the suckling period, conducting early weaning, conducting grazing, supplementary feeding and dynamic nutrient supplying in different developmental stages, conducting timely mating, conducting feeding and management of the primiparity ewes in the gestation period, collecting and breeding the lambs and the like, the ewes can give birth to one more batch of lambs within the feeding age limit, the birth weight of the lambs is increased, the death rate of the lambs is reduced, the lamb survival rate of the primiparity ewes reaches 97%, the reproduction and utilization rate of the ewes is increased, the reproduction rate is greatly increased, the interval of reproduction generations is shortened, and the feeding benefits are increased.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a full-range and high-efficiency breeding method for early breeding of Tibetan sheep. Background technique [0002] Tibetan sheep is the main dominant livestock breed on the Qinghai-Tibet Plateau, and has strong adaptability to the harsh natural environment of high cold and hypoxia, which is inferior to other sheep breeds. Qinghai Province has a wide distribution area of ​​Tibetan sheep, with as many as 11 million sheep. As one of the five major pastoral areas in the country, comprehensive factors such as the wide distribution of sheep in our province, the limitation of breed selection, and the importance of the ecological environment determine the province's sheep breeding. The sheep industry is a development model based on Tibetan sheep. However, at present, Tibetan sheep production in our province is still dominated by grazing. Due to the harsh natural environment of...
