Embodiment 1

[0016] The present embodiment provides a method for raising and managing male goats in the mating period, comprising the following steps:

[0017] (1) Select rams that are strong and strong and have excellent genetic performance for single-pen breeding, with a breeding area of ​​4m 2 / sheep, the temperature in the sheep house is kept at 25-30°C, and the ventilation is good;

[0018] (2) Breeding rams adopt a combination of barn feeding and grazing: when barn feeding, feed three times a day, 7:00-8:00 in the morning, 35% of the whole day's food intake; 12:00-noon At 13:00, feed 25% of the whole day's food intake, and at 20:00-21:00 in the evening, feed 40% of the whole day's food intake, and feed a fresh egg every day; when grazing, the daily grazing time is not less than 4 hours, Grazing is done twice in the morning and in the afternoon; when grazing, they should be grouped separately, managed separately, and kept away from the ewes. At the same time, keep the environment qu...

Abstract

The invention discloses a raising and managing method for rams in the hybridization stage. The method comprises the following steps of selecting solid and robust stud rams with good heredity for performing one-loop raising, wherein the raising area is 3-5 m<2> per ram, the temperature inside a sheep house is kept at 25-30 DEG C, and ventilation is good; adopting the house raising and pasture combined mode for raising stud rams, wherein during house raising, feed is put three times every day, and one fresh egg is fed every day; during pasture, the pasture time is not shorter than 4 h every day, and pasture is performed two times in the morning and at the afternoon every day; during pasturing, independent groups are needed, independent management is implemented, the rams need to get away from ewe groups, meanwhile, the pasture environment is kept silent, and the rams are sheltered from rain and warmed. A feed additive is added into supplemental concentrated food, the sexual behavior of rams in the hybridization stage is obviously improved, the sexual reaction time is short, semen collection is easy, and the sperm quality is obviously improved.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a breeding and management method for billy goats in the mating period. Background technique [0002] As the saying goes, "female has a good litter, and males have a good slope". Excellent breeding rams are very important for the improvement of breeding breeds. [0003] In the promotion of goat artificial insemination technology, there is a prominent problem, that is, most mutton sheep are in seasonal estrus, and the mating time is relatively concentrated, so the frequency of semen collection of rams must be increased during this period. High-intensity semen collection leads to excessive blood loss in rams, stagnation of deficiency, kidney deficiency and yang failure, endocrine disorders, and insufficient nutrition, resulting in decreased sexual function, which in turn leads to decreased libido, reduced ejaculate volume, and poor semen quality , the conception rate of ewes in e...
