Novel method for increasing reproductive rate of sheep

Abstract

The invention belongs to the technical field of livestock farming, and discloses a novel method for increasing the reproductive rate of sheep. The method comprises the following steps: building a special breeding sheep house, a special delivering sheep house and a special lamb fattening sheep house for later use; preferably selecting stud rams and ewes; raising in the breeding sheep house group bygroup, and feeding with special feed for the stud rams and special feed for the ewes; feeding pregnant ewes with special feed for pregnancy, and transferring the ewes expecting to give birth to the delivering sheep house; weaning lambs in advance for fattening; enabling the ewes to enter the sperm supplementing stage for a new round of pregnancy preparation. The method provided by the invention is simple and convenient, and the reproductive rate is high; artificial insemination is not involved, so that the workload and the cost are reduced; use of gonadotropin is not involved, so that no hormonal medicinal residue in the bodies of the ewes is guaranteed, healthy reproduction of the ewes is facilitated, and the health and the safety of the lambs are guaranteed; the sheep houses are thickened for warming in winter and heat insulation in summer; windows of the sheep houses are enlarged, so that the lighting area is increased, the heat-preserving effect is enhanced, promotion of calcium absorption is facilitated, ventilation is facilitated, and air freshness and air circulation are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a novel method for improving the reproductive rate of sheep. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Sheep is the collective name of the Ovis subfamily, Mammalia, Artiodactyla, Bovidae, Ovis subfamily, and is one of human livestock. Hairy four-legged ruminant that is a source of wool. The coat color is mainly white. my country mainly raises goats and sheep. With the progress of society and the development of economy, the demand for both mutton products and wool products has increased significantly. Therefore, in recent years, more and more attention has been paid to the reproductive rate and quality of sheep. Therefore, how to improve the reproductive rate of sheep is an urgent problem to be solved. However, the methods provided in the prior art are complex, difficult to op...

AI Technical Summary

Problems solved by technology

[0005] (1) The artificial insemination or assisted insemination methods provided in the prior art are complex, difficult to operate, and have a low reproductive rate;

[0006] (2) The prior art involves artificial insemination or assisted insemination, which increases the workload and costs; the use of gonadotropins is often used, which cannot guarantee whether there are hormone drug residues in the ewes, which is not conducive to the healthy reproduction of ewes, and cannot be guaranteed lamb health and safety;

[0007] (3) The environmental conditions of sheep houses in the prior art are relatively poor, which is not conducive to lighting, heat preservation and ventilation, and group feeding, production feeding and lamb fattening feeding have not been done, resulting in poor production conditions and easy infection; poor fattening effect result;

[0008] (4) In the prior art, the feed added when feeding sheep is generally ordinary feed, with rough and miscellaneous ingredients and few nutrients, and often contains hormone ingredients to promote the growth of sheep, but the potential side effects will be serious in the long run Nutritional health of rams and ewes directly affects the source of fine-bred lambs and reduces the reproductive rate
