What is the feeding technology and management of mutton sheep?

1. 1 Easy to manage and save costs.

Centralized captivity, unified management, improve feed utilization efficiency, and give play to the advantages of forage formula. Build a standardized shed for centralized captivity, 1 person can manage hundreds of sheep. Forage is very convenient to feed, the environmental sanitation conditions are improved, it is easy to clean, the disease death is reduced, the cold resistance and fat preservation are unified, the management is unified, the lambs are unified, and the slaughter is unified.

1.2 unified varieties and rapid propagation.

It is convenient to promote the introduction of high-yield mutton sheep for unified feeding, fattening and processing production, accelerate the popularization and application of advanced sheep breeding technology, realize the rapid transformation of breeding structure and improve breeding efficiency.

2. Restrictions on traditional stocks

2. 1 constraints of grassland

The state implements the policy of forbidding grazing and stopping grazing, so grazing on grasslands is restricted, and some grasslands that are convenient and idle in agricultural and forestry fields cannot graze. The grassland area is fixed, the rotational grazing area is reduced, and all kinds of livestock cross grazing, which leads to the decrease of grass yield, and the situation of cattle and sheep is obviously worse than that of captive cattle and sheep.

2.2 manpower constraints

With the increase of grazing farmers' age, their physical strength is no longer suitable for grazing, and their life with water for grazing in four seasons is unrealistic, which is restricted by poor grazing conditions, backward transportation and long distance. There is a large amount of forage in winter, which is restricted by poor infrastructure.

3. Infrastructure construction

3. 1 structure of standard pen

It is necessary to establish a reasonable layout of pens for house feeding and captivity. Pens should be scientifically planned, built in places with good sunshine and in line with the hygienic conditions of feeding environment, and obtain animal health supervision certificates. Pen houses should be built according to the requirements of aquaculture development and the standard of not less than 200 sheep per house. Ensure smooth waterways, convenient access, and corresponding sewage and pollutant treatment facilities.

3.2 set up a special column ring

Set up a special delivery room for sick sheep, a lamb shed, a fattening shed, a sheep breeding shed, a sheep breeding shed and an isolation shed, so as to facilitate the feeding of captive sheep according to different ages, breeds and physical conditions.

3.3 Configuration of special machinery

Sheep farms should be equipped with large and medium-sized forage automatic crushing mixers and forage feeders, which is convenient for sheep to prepare forage according to different conditions and scientifically prepare the weight of concentrated feed.

3.4 Set up a special storage room.

The forage storage room should be enough to store forage for 3 ~ 4 months sheep.

4. House feeding and captive management

4. 1 improved varieties

The male parent of imported mutton sheep should choose excellent breeds with large size, fast growth, high reproduction rate, strong adaptability, high meat yield and obvious breeding benefits. Use local ewes for hybrid improvement and purebred promotion.

4.2 Scientific Breeding

Using synchronous estrus technology and artificial insemination technology to carry out scientific breeding, wear ear numbers for male and female sheep, compile breeding files, record the number of breeding sheep, breeding time, breeding methods and lambing situation in detail, control the inbreeding of male and female sheep in a planned way, and avoid breed degradation caused by inbreeding.

The first ewe is in estrus for 6 ~ 8 months (Hu sheep), and the ram 18 ~ 24 months can be mated. Sheep are most productive when they are 3-5 years old. Before artificial insemination, ewes bred for the first time must pass the trial of breeding rams, and naturally mate according to the input of 30 ~ 35 ewes 1 ram.

4.3 Reasonable scale

Breeding high-yield mutton sheep should be carefully managed to avoid large-scale feeding across the board, and the breeding scale should be rationally planned according to the actual ability, so as to get twice the result with half the effort and improve the breeding efficiency.

4.4 Lamb feeding

After the lamb is born for 20 days, it can supplement milk powder, increase the amount of roughage and improve the digestion and peristalsis of the lamb's stomach. Increase the ewe's total nutrient concentrate 1 ~ 1.5 kg, and add more than 2 kg of concentrate for multi-lamb ewes, so that ewes can secrete more high-quality milk and improve the lamb's autoimmune ability and survival rate. Lambs born at the age of 45 days can be weaned and gradually fed in circles, and the proportion of concentrate and roughage will gradually increase after 60 days.

4.5 Adult sheep feeding

Breeding sheep refers to the stage from successful weaning of lambs to formal fattening. The feeding goal at this stage is mainly to meet the growth and development needs of sheep and ensure that sheep are suitable. Choose forage grass with good nutritional value and feed it with concentrated feed until it enters the fattening stage. The daily feeding amount of complete concentrate feed is not less than 300 g, and the feeding amount of coarse feed is not less than 3 ~ 4 kg. Every adult ewe is not less than 0.6 ~ 1 kg of complete concentrate every day.

5. Preparation of complete feed

When preparing forage grass, experts should be hired to prepare reasonable forage grass, and single coarse feed such as straw and silage corn should not be fed for a long time. Green grass should be crushed and full-price concentrate should be added.

According to the characteristics of breeding pregnant ewes, lambs, fattening and breeding rams, different proportions of forage grass are prepared for feeding. Combined with the nutritional needs of sheep at different growth stages, feed with comprehensive nutrition, diverse varieties, strong palatability, easy digestion and reasonable collocation of fine, coarse and green feed was prepared. After entering the winter and spring season, due to the lack of green feed, silage and forage with high vitamin content were selected to ensure sufficient nutrition for sheep.

6. Prevention and control of disease virus

6. 1 Regular disinfection

Keep the environment inside and outside the sheephouse clean, and clean up the feces and other dirt in time. Disinfect the fence every week 1 time. Dead sheep carcasses should be buried or burned to prevent the epidemic of infectious diseases. Personnel entering and leaving the vehicle must register for disinfection.

6.2 disease prevention

Every spring and autumn, all sheep are injected with quadruple vaccine (rapid epidemic, sudden gangrene, lamb dysentery and enterotoxemia) 1 time. Centralized inoculation of foot-and-mouth disease and small ruminant plague. Serological detection of 1 sheep brucellosis is carried out every six months to purify the transmission of brucellosis.

6.3 Regular deworming

Every year, sheep are regularly dewormed, and internal and external deworming drugs are selected to regularly drive out Fasciola hepatica, filariasis and nematodes parasitic on sheep. Concentrate 1 medicinal bath in autumn to kill the spread of parasites such as sheep mites in vitro.

6.4 Strictly lead the sheep

Every imported sheep must be strictly monitored for zoonosis and brucellosis. Sheep should be introduced from non-epidemic areas to meet the conditions of transportation in different places. Imported sheep can only be raised in the same group after strict isolation and normal clinical examination.
