Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below in conjunction with examples. It should be understood that the following implementations are given for the purpose of illustration only, and are not used to limit the scope of the present invention. Those skilled in the art can make various modifications and substitutions to the present invention without departing from the purpose and spirit of the present invention.

[0023] The experimental methods used in the following examples are conventional methods unless otherwise specified.

[0024] The reagents and materials used in the following examples are commercially available. The cysteamine used was from Sigma Company (St. Louis, MO, USA), and was a white powder with a melting point of 97.0-98.5°C.

[0025] (1) Choice of ram:

[0026] 480 2.5-month-old Small-tailed Han sheep rams were selected from Shandong Koushi Animal Husbandry Co., Ltd., and the rams were randomly divided into 8 grou...

Abstract

The invention relates to the field of livestock and animal breeding, and particularly discloses a method for improving sheep semen quality. The method initially discovers that semen activity of the ram can be remarkably improved when a ram orally takes 9.0-15.0mg/kg*BW of cysteamine every day. The cysteamine is added into feed, so that the ram obtains the cysteamine, the cysteamine can be conveniently added as needed, adding dosage is timely changed, and wide-range popularization and application of large-scale sheep breeding can be achieved. The method is applied to sheep breeding, safety of sheep meat products can be ensured, and rapid development of meat sheep breeding industry is certainly facilitated.

Description

technical field [0001] The invention relates to the field of animal husbandry and animal reproduction, in particular to a method for improving the quality of sheep semen. Background technique [0002] The problem of competition between humans and animals for food has become increasingly prominent, and vigorously developing herbivorous animals is one of the main solutions advocated by the state. The sheep raising industry in agricultural areas has gradually formed a large-scale, standardized and intensive breeding situation. With the continuous advancement of large-scale breeding facilities, especially the relatively limited movement area of ​​breeding sheep sheds, the quality of breeding sheep semen has generally declined in recent years, which directly leads to a decline in the conception rate of ewes in different regions, and then Affected the market supply and price of mutton. According to industry statistics, my country's mutton output in 2015 was 4.41 million tons, a ...
