Method for producing Australian-han third-generation ram through hybridization of small tailed han ewe and Australian white ram

Abstract

The invention discloses a method for producing an Australian-han third-generation ram through hybridization of a small tailed han ewe and an Australian white ram. The method comprises nine steps, and the ram is fed with specially prepared ram oestrus strengthening feed. By means of hybridization and breeding, artificial insemination technique and hybrid vigor, the filial generation inherits the superior characteristics of small tailed han sheep and Australian white sheep, the produced third-generation ram has 87.5% of genes of the Australian white ram, the size is large, growth and development speed is high, meat production rate is high, and meat quality is good.

Description

Technical field:

[0001] The invention relates to the field of sheep breeding, in particular to a method for producing Aohan third-generation rams by crossing small-tailed Han sheep ewes with Australian white rams. Background technique:

[0002] Small-tailed Han sheep is an animal under the Bovidae and Ovis subfamily. It is a breed of sheep with both meat and fur in my country. It has fast growth, early maturity, strong fecundity, stable performance and genetics, and strong adaptability. It has been designated as a famous livestock breed by the country. , known as China's "National Treasure", the world's "Super Sheep" and "High Leg Sheep". And was included in the "National Animal Genetic Resources Protection Catalog". It is not only one of the best projects for farmers to get rid of poverty and become prosperous, but also the most secure project for the government's poverty alleviation work. It is also an important measure for the country to close mountains and return farmlan...

Embodiment Construction

[0020] Below by embodiment the present invention is described in further detail:

[0021] The method for producing Aohan third-generation rams by crossing small-tailed Han sheep ewes with Australian white rams is characterized in that it includes the following steps:

[0022] Step 1: Rectify the sheep flock, 3-4 months before mating, gather the well-developed small-tailed Han sheep ewes to form ewe flocks, eliminate ewes that are not suitable for breeding, and carry out brucellosis quarantine on the flocks;

[0023] Step 2: short-term optimal feeding, choose high-quality forage grass, free drinking water for the sheep, supplementary feeding with concentrate, and feed each sheep 300-400 grams per day;

[0024] Step 3: Prepare for mating Australian white rams. 30-40 days before mating, collect semen once in the first 5-7 days, then 3-5 days, and last 2-3 days, and conduct semen quality inspection. Those who pass the test will be listed The mating ram plan, according to the char...
