Problems solved by technology

The traditional four-season natural grazing breeding method of fine-wool sheep in my country makes the evenness of the wool clumps grown throughout the year very poor, and the fineness of the hair tip is very thick, and gradually becomes thinner towards the hair root. It not only affects the breeding benefits of herdsmen, but also fails to meet the needs of my country's wool spinning enterprises and imports a large amount of Australian wool at high prices, thus affecting the income of my country's wool spinning enterprises

Embodiment 1

[0033] In the grassland pastoral area of ​​Sunan Yugur Autonomous County, Gansu Province, 300 fine-wool sheep breeding ewes were selected as the experimental group for the experiment:

[0034] 1. From June to September, during the period of high grass growth, the ewes gradually recover from the late lactation period to the weaning period, and their own nutritional requirements gradually decrease. The method of artificially limiting the grazing time is adopted to control the intake of nutrients. The sheep go out to graze at 10:00 in the morning, eat freely until 18:00 in the afternoon, and graze naturally for 8 hours throughout the day. .

[0035] 2. During the yellow grass period from October to mid-November, the grass starts to turn yellow and the nutrition decreases. At this time, the ewes are in the empty period before mating, and their nutritional requirements are relatively low. Adopt the way of natural grazing free feeding to control the intake of nutrients. The sheep g...

Abstract

The invention provides a breeding method for improving the wool tuft uniformity of fine-wool sheep, relating to the technical field of livestock breeding. The breeding method provided by the inventionis divided into 5 breeding phases according to the physiological cycle of the fine-wool sheep and the nutrient changes of a grassland in four springs, different breeding schemes are respectively adopted in different breeding phases, so that nutrient intake can be balanced to guarantee that year-round nutrients are taken in evenly, and the wool tuft uniformity is guaranteed to be excellent. The breeding method provided by the invention can effectively improve the wool tuft uniformity and enhance the comprehensive quality of fine wool and the selling price of the wool. Meanwhile, the method canfurther effectively prevent the disease of a digestive tract such as diarrhoea caused by dewy forage grass picked and eaten during herding in summer and autumn as well as by tender grass picked and eaten during spring, and can avoid the occurrence of accidents such as slipping, hurt due to falling and abortion as well during herding in winter, thereby improving the culture benefit of the fine-wool sheep. The method is simple, easy, and appropriate for the main production areas of the fine-wool sheep in the northern pasturing areas of China, and has very good prospects in popularization and application.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a breeding method for improving the evenness of wool tufts of fine-wool sheep. Background technique [0002] Wool is one of the main products of fine-wool sheep. The quality of wool directly determines the price of wool and the breeding benefits of fine-wool sheep. The evenness of the tuft is the change of the fineness along the length of the tuft, that is, the uniformity of the fineness of a wool fiber. The evenness of the tuft is an important indicator for evaluating the quality of fine wool. It determines the textile performance of wool. Therefore, it is closely related to the price of wool. Related, the better the evenness of the wool tuft, the more uniform the fineness, the greater the breaking strength of the wool, the better its textile performance, and the higher the price. The evenness of the wool tuft is not good, and even weak knots appear If the ...
