A detailed explanation of the main points of breeding techniques of Lake Sheep in 2019

Hu sheep is a unique white lamb breed in China, which is mainly distributed in the Hangjiahu Plain in Taihu Basin, which is suitable for house feeding all the year round.

I. breed selection of Hu Sheep

In order to improve the economic value of Hu sheep breeding, some farms simply emphasize the body type of breeds and blindly pursue Hu sheep breeds with larger body size and thicker crown, but most of the sheep breeds with this characteristic are not purebred Hu sheep, which leads to the introduction of small tail Han sheep similar to purebred Hu sheep in most farms, which naturally does not realize the economic benefits of Hu sheep culture.

In the process of breed selection, purebred Hu sheep should be introduced to the regular farm, and it is best to choose those sheep with pedigree files and obvious breed characteristics. Only pure Hu sheep can really breed Hu sheep with good breeds and good economic benefits, so as to improve the economic benefits of the farm.

Second, the breeding density of Hu sheep.

The temperament and characteristics of Hu sheep determine that it is more suitable for enclosure breeding, and it is not easy to graze, otherwise, there will be fractures, miscarriages or allergies due to mosquito bites, which will reduce the economic benefits of Hu sheep breeding.

Therefore, special attention should be paid to the breeding density. Generally speaking, the garden can raise about 5 lake sheep per mu. Exceeding this number will cause far-reaching harm to the environment, which is not conducive to the sustainable development of lake sheep farming.

Third, the daily management of Hu sheep

1. Feed supply. Hu sheep have various feeding habits. All kinds of grass, crop straw, vegetable leaves, blighted grain, bean curd dregs, vegetable cakes, silkworm sand, grain bran and so on can be used as fodder. At the same time, new feed resources are actively developed, and sheep-raising techniques such as ammoniation, alkalization and silage are applied to feed sheep by planting high-yield and nutritious artificial forage in winter fallow fields or other open spaces.

2. In addition to doing a good job in routine management, focus on the following points.

3. Ensure adequate and clean drinking water and add some salt appropriately.

4. Tap the lactation potential of ewes and implement the technique of "one mother with two or more lambs".

5. Pay attention to the timely weaning of lambs. The lactation period is generally controlled within 45 days of age.

6. Mutton sheep (especially old sheep) should be strengthened for 1-2 months before sale in order to improve meat quality, increase meat value and increase sheep benefit.

IV. Disease Prevention of Hu Sheep

1. Sheep black fast epidemic: injection of "sheep black fast epidemic, lamb dysentery, sheep enterotoxemia, sheep death" quadruple vaccine prevention, the treatment effect is poor.

Disease No. 5: vaccination against "Disease No. 5".

In short, if there are abnormal situations such as standing still, not eating, drowsiness and so on, as soon as they are found, targeted measures should be taken immediately to control the adverse effects to a minimum.

5. Breeding and breeding of Hu sheep

The breeding season of Hu sheep is generally arranged in April-May in spring, lambs in September-October in autumn, and one child a year. However, some sheep can also appropriately adjust the breeding season, breed from September to November, and give birth to lambs from February to April the following year, so as to achieve "two births a year or three births in two years". However, sheep born in autumn and spring are not suitable for breeding, and can only be used in mutton sheep production.
