Pig breeding technology

The boar is small in size, with fragrant meat, thin skin, and high lean meat. The Xiang pig has strong adaptability, high reproduction rate and high feeding value. Breeding pig sheds should be built in a sunny, dry, ventilated, secluded place.

The pig house is plastered with cement or paved with floor tiles. Each breeder has an effective quarter size of 4 square meters. The breeder's fragrant pigs are mainly fed with green and blue feed to ensure that the smell of pork is pure. Commonly used feeds include corn, small tables, rice, wheat bran, rice bran, bean cake, and peanut cake. Different stages of the pigs require different feed protein content, 14%-15% for 2-3 month old pigs, 12%-14% for 4-6 month old pigs and lactating sows, and 8% for empty sows -10%; breeding pigs are 13%-15%. The amount of concentrate feed, 1.5-2 kilograms per day for large pigs and 1-1.5 kilograms per day for young pigs. Powder feed plus water stirring until dry and wet suitable for feeding. The pelleted feed is fed directly to ensure sufficient drinking water, green feed is washed, minced and then mixed with the fine feed, or it can be fed after the feed is fed, not chopped. Big pigs were fed 3 times a day and piglets were fed 4 times a day. The sow’s prepubescent period is 4 months old, and it is best to breed at 8 months of age, and it is not until 6 months of age that breeding is possible. The sow is ready to feed material to the pig before it is delivered. The mother pigs are good and the nurses are strong. The pigs are not accustomed to being frequently approached and require a quiet place. The light of the house should not be too strong. After the newborn piglet has dried hair, it can move in the pen and suck breast milk. The piglets were fed at 30 days of age, weaned at 50 days and kept in isolation from the sows. Pigs that are not ready for breeding are bred during lactation, otherwise they will affect their growth and quality of suckling pigs. In places where the environment is free from pollution, the pigs have shown the advantages of extensive management, strong disease resistance and so on. However, the introduction of industrial pollution in more serious areas of aquaculture, special attention should be paid to environmental health, regular cleaning sheds, changing utensils, disinfection, ground replacement litter. It is forbidden to drink sewage from pigs or to wash green feed and utensils with sewage. Feces and waste are stacked and disposed. At the same time, all pigs were vaccinated according to the local epidemic. Newborn piglets should also pay attention to the prevention of red peony and white peony.
