Industrial breeding techniques of Mutton Sheep

With the rapid development of social economy, people's quality of life and living standards continue to improve, and the demand for meat is increasing, thus promoting the steady development of the breeding industry. Meat sheep is a delicacy on people's dining table, so how to rapidly develop breeding industry and increase the economic benefits of farmers under the premise of ensuring people's food safety has become the content that relevant personnel need to explore deeply. The following briefly analyzes the related contents of factory breeding of mutton sheep for reference.

1. Reasonable selection of mutton sheep breeds

There are many kinds of Mianyang sheep suitable for industrial breeding and production of mutton sheep, such as Hu sheep, small-tailed Han sheep, etc. in China, and Dorset sheep and Poll Dorset sheep in foreign countries. No matter which breed it is, the primary consideration is its ability to give birth. Try to produce two or three lambs per litter. Then, it is necessary to ensure that the sheep mature early, grow quickly, and feed easily, and can adapt to the local climate.

Environmental conditions such as temperature, especially when sufficient feed cannot be ensured, should consider the roughage tolerance and cold resistance of mutton sheep. Generally speaking, during the factory breeding of mutton sheep, the small tail Han sheep is usually selected as female parent, while Dorset sheep and Poll Dorset sheep are selected as male parent to carry out binary hybridization, thus not only ensuring the advantages of high yield, early maturity and coarse feed tolerance of small tail Han sheep, but also retaining the advantages of large body size and fast growth of exotic sheep.

2 Creating sheep houses

When creating sheep houses, the primary consideration is the location of sheep farms. It is necessary to choose a position with higher terrain, excellent ventilation, higher drainage capacity and sunny leeward, while ensuring sufficient and convenient water supply. The creation style of the sheep house needs to refer to the stock. scientifically set

Area of sheep house, sports ground and feed room. Generally, the area of sheep house should ensure that each adult sheep occupies 1.2~1.5 m2 space, each breeding sheep occupies 0.7~0.8 m2 space, and each lamb occupies 0.5~0.6 m2 space. In addition, if the ewes are in early lactation or late pregnancy, each one needs to occupy 2.2 - 2.5 m2 of space. The daylighting and ventilation of the sheep house should be ensured. The heat preservation work should be done well in winter and the ventilation should be done well in summer. Combined with the specific conditions, semi-enclosed or fully enclosed sheep houses can be created. If the sheep house is semi-enclosed, it needs to buckle plastic film, not only sunny, but also warm. As an important place for factory breeding of mutton sheep, people mistakenly thought that raising mutton sheep did not need to create a sports place. In fact, proper exercise could not only ensure the health of mutton sheep, maintain good growth, reduce the incidence of sheep, but also improve the quality of mutton efficiently. The area of the general sports field is about 3 times the total area of the sheep house, and the site should ensure a certain slope, so that there is no ponding after rain. In summer, pergolas can be erected above the playground as a place for mutton sheep to rest at night. The general playground wall height is about 1.5 m. In the sports field, some grass that is resistant to trampling, low, sheep like to eat and will not affect the quality of mutton can be planted appropriately, such as corn grass, green bristlegrass, mountain onion, crabgrass, etc. These plants can make the meat more fragrant and improve the quality of sheep after eating. Artificial grassland or natural grassland can also be used as a playground for mutton sheep, thus improving the level of factory sheep raising. It should be noted that when using natural grassland as a sports ground, plants affecting mutton quality need to be removed in advance.

3. Strengthen the feeding management

3.1 Formulate feeding standards for feed

During the factory breeding of mutton sheep, attention should be paid to the supply and yield of feed, which is an important condition to ensure the quality of mutton sheep. Stable forage supply channels should be established, and feed sources should be fully utilized to ensure that concentrate and roughage are reasonably matched, grass and hay are scientifically matched,

Rich and balanced nutrition helps sheep grow. When formulating the feeding standard of feed, it should be determined according to the stock of sheep. Generally, adult sheep should eat 2.5 kg hay and 0.25 kg concentrate feed every day. Sheep should eat 1.7 kg hay and 0.25 kg concentrate daily. According to this standard, the breeder can calculate all the feed weight of the year, and add about 10% fluctuation to ensure the annual consumption of mutton sheep.

Because the method of grazing and feeding has been banned nowadays, green hay has become an important feed for industrial farming of mutton sheep.

Consider its quality, aroma, choose palatability good green hay for feeding. In some farming areas, corn stalks that are not moldy can also be used as

It is a good forage.

3.2 Salt supplementation of drinking water for mutton sheep

Salt supplement in drinking water is an important part of daily management in mutton sheep breeding. In previous breeding experiences, it happened in the middle of summer

Without salt supplement in the feed, when entering winter, the overall physique of the sheep is reduced, unable to withstand the cold, a large number of frozen problems. It is necessary to ensure the cleanliness of sheep drinking water. It is not allowed to let sheep drink stagnant water or river water. In winter, it is not allowed to drink water containing ice slag to prevent abortion of ewes. It should also be ensured that when the sheep eat hay containing beans and other hay, they cannot drink water immediately to prevent abdominal bulge. At the same time, after using urea as an additive, drinking water is not allowed within 30 minutes to prevent ammonia poisoning. Breeders need to clean water tanks for sheep regularly to ensure safe water quality. Before drinking water, the water stored in the tank should be emptied, and the daily drinking water in the tank should be replenished in time to ensure that each sheep can drink enough water. It is generally necessary to control the number of drinking water, usually 3 to 4 times a day in summer and 2 to 3 times a day in winter. The salt in the water should be selected from animal husbandry salt or feed salt produced by regular manufacturers. To reduce the workload, sheep can be fed salt mixed with trace elements. Generally, the amount of salt supplement needs to be adjusted according to the season. In summer, the excretion rate of mutton sheep is faster, so it needs to supplement more salt. In winter, mutton sheep eat inferior forage, so it needs to supplement less salt. Salt supplementation is usually required once a day in summer and once every 3 days in winter. The general salt supplement capacity is 0.5 kg per 100 sheep, and it can also be operated according to the feed instructions. Concentrate can be mixed with salt, or a separate trough can be set up for the sheep to supplement salt. Or compress it into blocks, cylinders, rectangles, squares, etc. and hang it for sheep to lick.

4. Epidemic prevention and deworming

Compared with the general livestock and poultry, sheep have a lower incidence of disease, so epidemic prevention work is relatively simple, usually in accordance with the veterinary department regulations, regularly for sheep

Group vaccination and so on. some areas require foot-and-mouth disease vaccine and sheep pox vaccine. In sheep, parasites such as tapeworm and roundworm generally exist, and Fasciola hepatica may also appear in adjacent wetlands. Usually ascaris can be treated with compound preparations, cestodes and Fasciola hepatica need to be treated with thiodichlorophenol. For details, see the drug description. It should be noted that these drugs all have certain toxins. Before using them, it is necessary to weigh the sheep and then use them in a targeted manner. In addition, in the sheep's body, may also be parasitic brain echinococcosis, also known as "turn Wo Feng", sick reaction for meat sheep around a direction circle. The main reason for its occurrence is that the polycephalous tapeworm larvae in dogs parasitize in the brain of sheep. The prevention method is to eliminate the tapeworm in dogs. When ill, can apply sulfadiazine sodium and abamectin joint treatment. If the disease is in the middle and late stages, surgery is needed. In the sheep's body, but also parasitic itch mites, mostly located under the cuticle of the skin, to dander for food. It has a serious impact on the production and development of mutton sheep. If it is sick and harmful, it is necessary to regularly bathe sheep with medicine, and apply the solvent of Dibaicao (general name: dicamba) with concentration of about 1% and the emulsion of muscarinic phosphorus with concentration of 0.05%.

In addition, sheep can also parasitize a sheep nose fly. It usually appears in midsummer, and it is easy to make sheep bow, snort, shake

The first case, the final waste of appetite, resulting in the death of mutton sheep. To prevent this situation, you can spray the surrounding of the sheep house with a solution of enemy herbs to kill the adult flies.

5 summarizes

In short, with the continuous development of social economy, people's quality of life is getting higher and higher, and the degree of mechanization is developing faster and faster.

Factory breeding can rapidly improve the yield of sheep, but also ensure the quality of mutton, related breeding personnel need to carry out this technology.

In-depth exploration, continuous improvement and perfection, thus laying a solid foundation for the development of aquaculture.
