For piglets, the practice of "two-stage, two-early, two-material" cultivation can greatly increase their survival rate and weaning weight. Practice has shown that using this breeding technique, piglets can reach a weight of 80kg or more on 45-day-old piglet, a litter weight of 165-190kg or more on 70-day-old piglets, and a bred rate of more than 90%. The so-called "two-stage" refers to the period of nursery feeding and the period of nursery. "Two mornings" refers to early sucking of piglets and early weaning; "two materials" refers to feeding and preservation of piglets. The main technical points are as follows:
1, before the birth of suckling piglets should be thoroughly cleaned, disinfected, prevent cross-infection, good prenatal preparation;
2. When a sow gives birth, there should be a person to deliver the child and give birth to a good birth. Help the suckling pig to drink colostrum early and fix the nipple. Piglets born within a few days of birth have weakness in their limbs, sluggishness and deep sleep. They should be squeezed to reduce death.
3, after the birth of piglets, should be cold insulation. Before 15 days of age, an infrared heat lamp (tank) should be added to the nursery column to facilitate the growth and development of piglets and increase the survival rate;
4, supplement minerals, in particular, pay attention to iron. To prevent anaemia, 1-2 ml of bupivacaine or ferrous sulfate per head muscle can be taken within 3 days of age. 7-30 days old mid-nurse piglets should be tempted to start early grazing. From 7 to 15 days of age, piglets should be induced to feed pre-suckling pigs with full-price premium quality to enhance gastrointestinal function. This is the key to early weaning.
5, through the incentives to feed quality piglets full price material, to meet the piglets due to the sow 21 days after the milk after the decline in nutritional needs, at this stage to do less to add Tim, one day not less than 4 times feeding. At the same time, it means hygiene, prevent cross-infection, protect against cold, and increase body resistance. The occurrence of diarrhea and timely symptomatic treatment to prevent the spread of the "three evils" is a key measure to ensure survival.
6, 30-45-day-old piglets in late lactation, through sedating and pre-feeding, are in a prosperous period, improve digestive function, growth is fast, is the best period for piglets to feed and increase weight, this time to do a good job Wang Shi, disputes. At 40-45 days of age, the piglets have strong resistance and should be cast off at the right time;
After 7 and 45 days of age, breast milk falls, and piglets should be weaned immediately. After weaning, feeding and management of piglets should be strengthened. The first is to do a good job of immunization: 20 days after the age should be timely injection of swine fever, piglet paratyphoid vaccine, 40-45 days after the timely injection of swine erysipelas, swine bacterin vaccine, 60 days should be injected again with swine fever vaccine, while WW vaccines should be injected and the control of yellow and white lice should be controlled to ensure that no epidemics occur and ensure healthy growth. Second, it is necessary to properly match the piglet feed: just after weaning piglet feed needs to transition about 1 week, but can not overeat, through 10-14 days, and gradually transition to full use piglet material. Third, we must do a good job of insulation and cold-proofing, improve the bred rate, and pay attention to grouping at the same time to ensure that the piglet is alive and full.
