Embodiment 1

[0019] (1) A method for improving the reproductive rate of Tibetan sheep, mainly comprising: 3 breeding time control points, 3 lambing time control points, and 3 weaning time control points; Breeding supporting measures need to be implemented during the period, including supplementary feeding of mating rams, basic nutritional regulation of ewes, and fattening of weaned lambs.

[0020] (2) The three breeding time control points are respectively March, October, and June of the following year.

[0021] (3) The three lambing time control points are August, next year March, and next year November respectively; the three lambing time control points produce summer lambs in August, spring lambs in March next year, and November next year. Produce winter lambs.

[0022] (4) The three weaning time control points are respectively October, June of the following year, and February of the following year.

[0023] (5) The interval between the breeding time and the weaning time is 15 to 30 d...

Embodiment 2

[0027] (1) A method for improving the reproductive rate of Tibetan sheep, mainly comprising: 3 breeding time control points, 3 lambing time control points, and 3 weaning time control points; Breeding supporting measures need to be implemented, including supplementary feeding of mating rams, basic nutritional regulation of ewes, and fattening of weaned lambs.

[0028] (2) The three mating time control points are early March, mid-October, and late June of the following year; the mating rams are 3 to 7 years old, and their body weight is not less than 50 kg. The supplementary feeding program is mixed daily feeding. Concentrate (corn, oat or high-quality soybean meal) 1.0kg, 1 egg, carrot 0.5kg, green hay ad libitum, the ratio of breeding male and female sheep is 1:30; Value; the age of the basic ewes is 3 to 8 years old, the body weight is not less than 48kg, the technical method of nutrition control is to take supplementary feeding measures from October to May of the following y...

Embodiment 3

[0034] (1) A method for improving the reproductive rate of Tibetan sheep, mainly comprising: 3 breeding time control points, 3 lambing time control points, and 3 weaning time control points; Breeding supporting measures need to be implemented, including supplementary feeding of mating rams, basic nutritional regulation of ewes, and fattening of weaned lambs.

[0035] (2) The three mating time control points are mid-March, early October, and mid-June of the following year; the mating rams are 3 to 7 years old, and their body weight is not less than 50 kg. The supplementary feeding program is mixed daily feeding. Concentrate (corn, bran or oats) 1.0kg, 1 egg, carrot 0.8kg, green hay ad libitum, the ratio of mating rams and ewes is 1:35; Value; the age of the basic ewes is 3 to 8 years old, the body weight is not less than 48kg, the technical method of nutritional regulation is to take supplementary feeding measures from October to May of the next year, 0.5kg of mixed concentrate...

Abstract

The invention relates to a method for improving a reproduction rate of Tibetan sheep. The method comprises the following steps of: respectively mating the Tibetan sheep at three different mating time control points; lambing the mated Tibetan sheep at three different lambing time control points; weaning lambed Tibetan sheep at three different weaning time control points; implementing breeding supporting measures among the mating, and lambing and weaning time points, wherein the three mating time control points are respectively in March of the year, in October of the year, and in June of the following year; and the breeding supporting measures comprise supplementary feeding of service rams, nutrition regulation of breeding ewes and fattening of weaning lambs. The technology and the method are comprehensive, convenient to operate, and capable of fully displaying potentials of reproducible ewes and giving birth to the Tibetan sheep for three times in two years, increase the number of the Tibetan sheep, effectively improve the reproduction efficiency, and are suitable for breeding and production of the Tibetan sheep.

Description

technical field [0001] The invention relates to a method for increasing the reproductive rate of animals, in particular to a method for increasing the reproductive rate of Tibetan sheep. Background technique [0002] Tibetan sheep are mainly distributed in the Qinghai-Tibet Plateau and its adjacent areas, and are one of the unique animal genetic resources of the Qinghai-Tibet Plateau. Due to the influence of the natural conditions and ecological environment factors of the Qinghai-Tibet Plateau, it has formed its unique ecological and physiological characteristics. Tibetan sheep are the basic means of production and living in alpine pastoral areas. They mainly provide nutritious, green and pollution-free mutton products, as well as industrial raw materials such as wool and leather. [0003] Tibetan sheep breeding is a basic link in the production of Tibetan sheep, and it is a necessary prerequisite for increasing the number of Tibetan sheep and improving the quality of Tibet...
