Rapid breeding method based on early growth characters of mountain merino sheep

Abstract

The invention discloses a rapid breeding method based on early growth characters of mountain merino sheep. The rapid breeding method based on the early growth characters of the mountain merino sheep comprises the following steps that 1, the newborn characters of the mountain merino sheep are authenticated according to a newborn stage; 2, weaning characters of the mountain merino sheep are authenticated according to a weaning stage; 3, animal models are established according to character parameters in the first step and the second step, and after model comparison is conducted, the animal modelwhich is suitable for genetic parameter estimation of the early growth characters of the mountain merino sheep is optimizedly selected; 4, a breeding comprehensive value I of the mountain merino sheepis calculated through the optimizedly selected animal model, and 5,the mountain merino sheep are selected and reserved from the high value to the low value of the breeding comprehensive value I according to the early growth characters. According to the rapid breeding method based on the early growth characters of the mountain merino sheep, through indicators of the early growth characters of newborn weight, weaning weight, average daily weight gain and weaning hair length appearance, the rapid breading method based on the early growth characters of the mountain merino sheep is established, sothat the difficult problem of early breeding of existing mountain merino sheep is solved, and the breeding result is more accurate and scientific.

Description

technical field [0001] The invention relates to a breeding method for alpine goats, in particular to a rapid breeding method based on early growth traits of alpine merino sheep, and belongs to the technical field of animal breeding and breeding. Background technique [0002] Merino sheep were first bred in Spain around the 15th to 17th centuries. Under the different natural environment and feeding and management conditions in various regions, various families of merino sheep are derived: such as Spanish merino, French Rambouillet merino, German Saxony merino, Australian merino, American Merino, South American Merino and Soviet Merino, etc. Although the wool quality of these Merino families is slightly different, because they all come from the same ancestral line, their genetic properties are stable and the wool quality is good, and they can be used as raw materials for high- and mid-grade worsted and high-quality woollen spinning. [0003] Fine-wool sheep, mainly of Merino...

Problems solved by technology

However, for the early breeding of Alpine Merino sheep, the current method is still to select individuals based on phenotype. This selection method is more traditional and primitive, requires high experience, and the final effect is not good.
