How to raise pigs after weaning? A detailed guide to the complete feeding steps

SummaryReasonable grouping: divide into pens by strength for raising, about 15 pigs per pen. Feeding: feed suckling pig feed for about 15 days after penning, then gradually transition to piglet feed, and appropriately reduce the feeding amount. Daily management: inspect the piglets regularly every day, clean the pig house in time to keep it clean and hygienic, and also control the room temperature at about 25-26°C. Epidemic prevention and deworming: within one week of raising, swine fever vaccine needs to be injected for epidemic prevention, and later the piglets also need deworming.

1. Reasonable grouping

Divide the piglets into pens by strength for raising, so that the body weight of the piglets in each pen is as close as possible. Generally, about 15 pigs can be raised per pen. Too many will cause crowding, which easily leads to ear biting and tail biting and affects the normal growth of the piglets.

2. Feeding

1. For weaned piglets that are transferred from self-breeding and self-raising, the feed should be changed slowly. After about 15 days of pen merging, suckling pig feed can be used, and one week later it can be transitioned according to a certain ratio to feeding piglet feed.

2. The number of feedings can be appropriately reduced, from 5 times per day to 3 times per day. The daily feeding amount can be calculated as 5% of body weight, then averaged into each feeding amount. If it is not finished within 60 minutes, it needs to be cleaned up and collected, and the feeding amount should be reduced next time.

3. If the piglets are bought back from other pig farms or markets, piglet feed with 3200 kcal digestible energy and 18% crude protein can be fed, such as pelleted feed or self-mixed feed. If self-mixed feed is used, it needs to be mixed wet before feeding, then pour clean water into the trough and add multivitamins.

3. Daily management

1. Inspect the piglets' mental state, diet, feces and urine, and breathing three times a day in the morning, at noon, and in the evening. If there is illness, treat it in time, and if necessary, isolate and treat it, and strengthen feeding management.

2. Let the piglets eat, sleep, and defecate at fixed points. When dividing into pens, let the piglets defecate at fixed designated positions. After about 3-5 days, they can defecate and urinate at fixed points, but in order to keep the pig house hygienic, the feces still need to be cleaned up in time.

3. The pig house needs to be cleaned about 3-4 times a day to ensure that the pig house is hygienic and clean. In summer, the pig house needs to be washed clean in the morning, and disinfected regularly once a week.

4. Newly weaned piglets are relatively sensitive to temperature, so appropriate warming measures can be taken to control the room temperature at about 25-26°C, which is beneficial to piglet growth.

5. For piglets bought from the market, around the 10th day each pig needs to be injected with sodium selenite VE injection: 1 milliliter.

6. If young male pigs have not been castrated, castration treatment is needed.

4. Epidemic prevention and deworming

1. For piglets from self-breeding and self-raising, standardized pig farms, or purchased from the market that have not completed immunization, within one week of raising, swine fever vaccine needs to be injected for epidemic prevention. After about 7 days, swine erysipelas, swine pasteurellosis, and piglet paratyphoid vaccine also need to be injected for epidemic prevention.

2. After the epidemic prevention work is completed, the pigs need to be dewormed. Ivermectin, levamisole, trichlorfon, fattening pig powder, etc. can be selected. After about a week, repeat deworming once, and different drugs can be used for deworming. Note that during deworming, the pig house must be kept hygienic, otherwise it will affect the deworming effect. It is best to disinfect once after deworming.
