Pig breeding method

Technical Field

The invention relates to a breeding method, in particular to a breeding method of pigs.

Background

Pork, one of the main domestic animals, the meat of pigs of the family of the swine, is rich in protein, fat, carbohydrate, calcium, iron, phosphorus and other nutrient components. Pork is a main subsidiary food in daily life and has the effects of tonifying deficiency, strengthening body, nourishing yin, moistening dryness and enlarging skin. At present, pork is wide in eating range and large in demand, so that the pig breeding demand is very high. Due to the problem of pig digestion efficiency, organic nutrient substances which are not digested in a large amount can be changed into excrement and discharged in the process of breeding pigs, so that the breeding environment is very smelly, and meanwhile, high-content organic matters in the excrement are easy to breed germs and mosquitoes, and very adverse effects are brought to the pigs and people and animals attached to a breeding farm; meanwhile, for the health of the pigs, the pigs are often fed with feed containing antibiotics or injected with corresponding vaccines, so that the antibiotics are enriched in the pigs, and further, the body of people eating the pork is adversely affected.

To solve this problem, a great deal of research has been done on the pig breeding process:

such as: the Chinese patent publication No. CN108739660A discloses an ecological healthy breeding method for pigs, which comprises the following steps of constructing a pigsty into a single-sided north-south permeable form, paving eucalyptus and masson pine padding in the pigsty, connecting a methane tank and a film shed at the tail end of a drainage channel, doping the crushed padding into new padding, putting the new padding into the pigsty again, putting crushed padding into the methane tank for fermentation, communicating methane to the pigsty and the shed, alternately driving live pigs into the shed for stocking and foraging, manually collecting the food materials foraged by the live pigs again, directly putting the food materials into the pigsty for secondary utilization, improving the utilization rate of the food materials, drying the fermented food materials after anaerobic oxidative decomposition by microorganisms, crushing the food materials, and putting the food materials into the shed as fertilizers; the method has the advantages of ensuring cleanness of piggeries and sheds, improving living environment of live pigs, reducing unnecessary consumption of the live pigs, promoting growth of plants in the sheds, improving utilization rate of materials in the whole circulation process and reducing emission.

For another example: the Chinese patent invention publication No. CN106259154A discloses a method for breeding ecological pigs, wherein an orchard is built around a pig farm, a methane tank is built under the pig farm, and the ground of a colony house activity area is cleaned; discharging the liquid dung into the methane tank; introducing the biogas slurry to an orchard around the pig farm to irrigate fruit trees; planting a shaddock tree or an apple tree in an orchard; planting tendril-leaved fritillary bulb between shaddock trees or apple trees; mixing the harvested sweet potato leaves and/or grapefruit leaves or apple leaves with pig feed and feeding pigs; numbering the unit colony houses, and putting pigs into an orchard for stocking in turn according to the numbers; according to the ecological pig breeding method, the purpose of realizing zero discharge of sewage is achieved by implementing the ecological breeding mode of pig-marsh-fruit-vegetable-pig, the colony house condition can be improved, the odor is reduced, the breeding of mosquitoes is reduced, the occurrence of swine plague is reduced, and the quality of pork is improved.

The following steps are repeated: the Chinese patent invention publication No. CN109275619A discloses a pig breeding method, which is characterized by comprising the following steps: (1) the adaptive-period culture method comprises the following steps: feeding piglets within a small range in an ecological farm within 16-18 days after the piglets enter adult pig breeding, feeding 5 meals each day, feeding 3-5 jin of green forage and 3-5 jin of corn forage to each pig at each meal, starting feeding the first meal at 4 points in the morning, and feeding one meal every 4 hours; (2) the culture method in the growing period comprises the following steps: after the adaptation period is 16-18 days, breeding the grown pigs in the growing period, stocking the grown pigs in a large area, enabling the pigs to have a large enough area for movement, ensuring the growth of a large amount of lean meat, enabling the meat quality to be fine and chewy, feeding the grown pigs for 4 meals each day, feeding each pig with 6-8 jin of green forage and 2-4 jin of corn forage, starting feeding the first meal at 5 am, and feeding one meal every 5 hours; (3) the pork pig stage breeding method comprises the following steps: when the whole growing period of the pig is 12 months, the pig is ready to be sold or killed as a pork pig, the pork pig period is 20-25 days before the sale or the killing, the main feeding purpose of the pork pig period is to ensure that the pig can quickly fatten and fatten, the pig in the pork pig period is fed with 3 meals each day, the feed for each meal is 6-10 jin of green forage, 4-6 jin of corn feed and 3-5 jin of rice bran, the first meal is fed at 6 o' clock in the morning, and the first meal is fed every 5 hours; when the pigs are bred in the growing period of adult pigs, the pigs need to be injected with vaccine and fed with anti-ascaris drugs.
