Breeding techniques of Hu Sheep

The ancestors of Hu sheep came from Mongolian sheep. According to records, at the beginning of the 10th century, a large number of residents in the Yellow River basin moved southward, and at the same time, the "big white sheep" (today's small-tailed Han sheep) raised in Hebei, Shandong and Henan were moved to the south of the Yangtze River. Under the natural conditions of the south of the Yangtze River, a good local breed was formed through long-term captivity and breeding (natural selection and artificial breeding). It is named Hu Sheep because it is mainly raised in the Taihu Lake basin at the junction of Jiangsu and Zhejiang provinces.

Feed Management of Hu Sheep breeding

1. Forage

To solve the problem of forage is to solve the problem of "2DB 3" in raising sheep. Forage includes fresh grass, green hay, rattan forage, silage, fruit leaves and silkworm leaves. When raising sheep in a family, they often eat what grass in what season, what they eat, and eat the same kind of forage every day (such as spring and summer, when fresh grass is abundant, then only fresh grass is fed every day), which is not only single in taste, but also too simple in nutrition, which will cause some diseases due to lack of nutrition. Should feed some green hay, fresh grass, conditional should add some silage, with feeding, in order to better balance nutrition, raise sheep.

Grass dries up in autumn and winter, and there is no source of green fodder for lake sheep. Large-scale farms should prepare silage in summer to prepare for overwintering, and qualified bulk farmers can also use silage. In addition to silage, overwintering materials should also store sufficient hay and rice straw (crushed, properly soaked in water and fed). Every day, a lake sheep consumes 7 kilograms of fresh grass, 3 kilograms of hay and 4 kilograms of corn silage (including wasted), and a lake sheep needs about 2,600 kilograms of fresh grass, 1200 kilograms of hay and 1500 kilograms of corn silage per day. An average of 0.067 hectares of pasture can raise 5 sheep (in captivity). The majority of farmers should recommend raising sheep and reserve forage according to the number of their flocks.

Sum up two sentences in terms of fodder: prepare enough forage and match it reasonably.

2. Concentrate

Concentrate is mainly supplemented and cannot be fed in large quantities. Generally, in the case of rich forage, it is mainly for ewes before mating, before and after pregnancy, lactating ewes, breeding rams, lambs and thinner sheep, the amount is controlled at about 0.25 kg per day (can be increased or decreased appropriately according to the size of the flock), it is more appropriate to add in the morning or evening. The main ingredients are generally: wheat bran, soybean meal, corn, rapeseed cake, green bran and so on.

Concentrate to sum up two words: starting from the actual situation, give priority to economic savings.

Concentrate recommended formula: corn 30%, soybean meal 10%, wheat bran 30%, rapeseed cake 16%, green bran 10%, salt 3%, mineral additive 1%.

Daily Management of Hu Sheep breeding

1. Rams and ewes should be raised in different circles

After weaning, the little Hu sheep should raise the male and female sheep in separate loops. The ewes can conceive normally after 4 months of age, but at this time, conception will affect the future ontogeny of ewes (for example, ewes that could have grown 50 kilograms can now grow only 35 kilograms). Raising in separate circles can also avoid inbreeding and keep the bloodline from decay. Hu sheep like to live in groups, so they should be kept in proper density and enclosed.

2. Feed enough, feed and water well

When Hu sheep eats all kinds of grass, it requires that the forage should be diversified and the forage should be clean (Hu sheep do not eat the fodder that has been trampled on by them, and feed them with a small amount of repeated feeding methods to reduce waste), and should not be moldy, feverish or yellowing. In terms of drinking water, use automatic water dispensers as far as possible (automatic water dispensers can drink water sanitary and save water, sheep can drink water at any time). If you use the sink to feed water, the sink should be cleaned every day and let the sheep drink freely.

3. Keep the enclosure dry and ventilated

The sheepfold should be covered with dry, non-mildew straw every day, and the straw should be cut short, otherwise it will wrap around the leg of sheep and cause unnecessary losses, such as miscarriage, etc.; the sheepfold for the bed should be cleaned every day, and there should be no accumulation of feces; whether it is the grass or the bed, sheep dung should be cleared regularly and fermented, so as to reduce pollution.

4. Trim hooves regularly, cut hair and take medicine bath in time.

After adulthood, the front of the hoof is keratinized and the "nails" are long, so it is necessary to trim the hoof regularly, otherwise it will affect its standing and walking, and serious hoof disease will be caused. Sheep shearing and medicine bathing every spring and autumn can dispel external parasites and prepare for summer and overwintering.

5. Do a good job of disinfection and epidemic prevention on a regular basis

It is also necessary to disinfect regularly in daily production. Bulk farmers can be disinfected with quicklime, plant ash or disinfectants sold in the market, once or twice a month. Large-scale farmers or large farmers should formulate disinfection plans and disinfection systems, and be equipped with perfect disinfection facilities, such as disinfection pools, disinfection changing rooms (equipped with disinfection ultraviolet lights), disinfection sprayers, etc., not less than 2 times a month, generally choose disinfectants sold in the market, the disinfectants used should be changed frequently, and cannot be used for a long time or a class of disinfection drugs, otherwise bacteria will have drug resistance to disinfectants. It is necessary to make a reasonable vaccination plan for sheep and vaccinate them on time, which is the most important part of disease prevention.

The Management method of Hu Sheep breeding ewe

1. Empty ewes

Empty ewes to grasp the fat feeling, not too fat (too fat will affect breeding), not too thin (too thin will cause prenatal or postpartum paralysis), generally a month before breeding, add concentrate (0.25 kg per sheep per day); feed more green and succulent feed, which is beneficial to ewes' normal estrus; feed a small amount of forage for many times, and appropriately increase the amount of grass at the last meal in the afternoon for night feeding If there are conditions in the breeding season, you can use the ram to test it once or twice a day, and make a good record.

2. Pregnant ewe

High quality green fodder and a small amount of concentrate should be fed in the early stage of pregnancy, but the fetus grows rapidly in the later stage, and the mother's demand for nutrition increases. Therefore, it is necessary to feed nutritious forage and pay attention to the reasonable collocation of many kinds of forage (adding some leguminous forage, high quality hay, silage, etc.); keep quiet in the pregnant ewe pen so as not to disturb the ewes suddenly Before giving birth, ewes should pay attention to observe the signs of delivery (red and swollen breasts, flattened cleavage, yellow milk, restless lying ewes, frequent drinking water, continuous urination, swelling and relaxation of the vulva, transparent yellowish mucus outflow), and strengthen nursing. Ewes with abnormal fetal position or dystocia should be assisted in time.

3. Lactating ewes

At this time, it is necessary to increase the milk yield of ewes as much as possible, and ewes should be fed with high-quality succulent green fodder, green hay and appropriate concentrate to meet the needs of ewes for various nutrients; for lactating ewes with weak physique, let its lambs feed to ewes with few lambs, good physique and good motherhood after eating colostrum.
