First, the economic analysis of breeding Xiang pigs

(a) the characteristics of Xiang pig:

Xiang pig has the characteristics of small body, thin skin, tender meat, fine bone, early maturity and high quality meat. Xiang pig's body is short and pithy, its coat color is all black, its skin is thin and tender, its bones are small, its head is medium straight, its mouth is medium long, its forehead and face have longitudinal wrinkles, its shapes are diverse, and its ears are small and lotus-shaped. Stretch forward slightly, droop slightly or extend horizontally to both sides, with short and thin neck, slightly concave back and waist, large abdomen, sloping buttocks, long tail, short and thin limbs, correct posture of forelimbs, lying pedicles on hind limbs and 5 pairs of sow nipples. Congjiang Xiang pig and Huanjiang Xiang pig have slightly different head shapes. Huanjiang Xiang pig's head is bigger, its forehead is wide, its mouth is short and thick, and its size is slightly larger than Congjiang Xiang pig's.

(2) Breeding benefit of Xiang pig:

Xiang pig is resistant to roughage, adaptable and easy to manage, but its growth is slow.

1, coarse feed tolerance: Xiang pigs are mainly free-range and often eat green feed such as weeds and fragrant rice, which makes milk pork have a special flavor. Each sow (2-4 months old) consumes an average of 0.2kg of concentrated feed and green feed 1kg per day. Pregnant and lactating sows consume an average of 0.4 kg of concentrated feed and 2 kg of green feed per head every day, with less feed consumption.

2. Strong adaptability: Xiang pig has strong adaptability to climate and seldom gets sick, but Xiang pig is timid and easy to escape. Therefore, the pigsty should be high, the environment should be quiet when raising, and the sports ground should be large.

3, easy to manage: Xiang pigs have early sexual maturity, are resistant to inbreeding and are genetically stable. Boars weighing 8kg at the age of 2 months will have climbing behavior and will be bred at the age of 3 months. Sows are in estrus at the age of 3 months and can be mated at the age of 4 months, with an average litter size of 7 ~ 10. The ratio of male to female is 1: 8 ~ 10.

4. Slow growth: Xiang pig has the characteristics of fast growth, long edge and fat edge in the early stage. The birth weight is 0.3 ~ 0.5 kg, and the average weight of each head is about 5 kg 60 days after weaning. Adult pigs weigh only 15 ~ 38 kg. Generally, it is most suitable to slaughter suckling pigs of 5 ~ 7 weeks old.

Thin skin and thin bones, tender meat and delicious taste, suitable for processing roast suckling pigs. At the same time, it also has broad prospects as an experimental animal or pet.

Second, matters needing attention in raising fragrant pigs

1, pay attention to the selection of pig breeds. When introducing pigs, the appearance, growth and development, pedigree, genetic defects and other aspects should be strictly investigated, and the breed characteristics are obvious and the reproductive function is vigorous, and the pedigree card of pigs should be brought back for future reference.

2. Pay attention to local environment. Imported fragrant pigs must meet the living consumption level of local people and the needs of economic development. At the same time, it is necessary to understand the characteristics of breeds, climate, feeding management and so on, so as to determine the local domestication measures after the introduction of Xiang pigs, create the necessary feeding management conditions and ensure the breeding benefits of Xiang pigs.

3. Pay attention to the season. When introducing fragrant pigs, it is best to spend autumn and winter in late spring after a warm summer when the temperature gradually drops, and it is required to do a good job of cold protection after wintering and gradually adapt to local natural conditions.

4. Pay attention to the age of pig breeds. It is better to introduce fragrant pigs to piglets about 4 months old or a little older. Pigs have a strong adaptability and can easily accept the changed external living conditions at a young age. Imported pig breeds should not be scattered, but should be concentrated in 1 or several pig farms to create good feeding and management conditions, and at the same time, make observation records, do a good job in breeding and breeding, and gradually promote them after adaptation.

5. Pay attention to epidemic prevention. When imported from other places, it is necessary to concentrate on isolated feeding for 1 ~ 2 months, strengthen epidemic prevention and disinfection, pay attention to eliminating and preventing the threat of endemic parasitic diseases and infectious diseases, and ensure the safety of imported pigs.
