Feeding management of piglet fattening
First, suckling piglets:
(1) Rescue of dead pigs: Some piglets seem to be dead after birth, but their hearts are still beating. For this kind of pig, the hind legs can be hung upside down, and then the ribs on both sides can be slapped to stimulate their breathing until the pig coughs.
(2) Eat colostrum well: the intestinal membrane can absorb immunoglobulin (antibody) within 24 hours after birth. Therefore, the nipples of piglets should be fixed after birth, so that every pig can eat colostrum. Let pigs develop disease resistance.
(3) Insulation: Piglets naturally like to be with sows after birth, so they should be put in an incubator so that they can eat milk. Conscious? Go back to the box.
(4) Iron supplementation: 3 days after birth, each muscle was injected with 100? 150mg iron preparation to prevent anemia.
(5) Castration: Early shearing of boars in commercial pig farms can reduce irritation and facilitate wound healing. It can be implemented within 24 hours to one week after delivery.
(6) Water supplement: After the piglets are born for 3 days, drinking water is supplied to ensure their growth needs.
(7) Feeding: In order to promote the growth of piglets and reduce the inadaptability of feeding after weaning, piglets can be fed within one week. The method is to sprinkle some suckling pig feed on the dry and clean chopping board. Four days later, when piglets start to eat suckling pig feed, they can use the feed trough. The rest is discarded every day and reused after cleaning the disinfection tank.
Second, weaned piglets: Weaned piglets mainly control the environment in pig houses and pigs, reduce stress and control diseases.
(1) When weaning, suckling pigs should still be fed for about a week, but not too much to prevent diarrhea. Then the piglet feed and piglet feed are mixed, and the proportion of piglet feed is gradually reduced. 10? 14 days, all piglets can switch to feed, and then they can eat freely.
(2) Weaned piglets have higher requirements on temperature. There should be an incubator in the weaning shed, and the bottom of the incubator can be covered with a layer of dry and clean wood.
(3) If the number of piglets weaned at one time is limited, they can be raised in the original nest. If there are many weaning litters, they should be put together according to the weight of piglets, and the feeding trough should meet the requirements and keep enough water.
(4) A litter of piglets is even and tidy in weight and can be weaned at one time. If individual piglets are thin, they can be fed in unweaned piglets with similar individual size for a period of time before weaning.
(5) Prevent bad habits such as biting tail and ear. It is also a nature of piglets to bite each other when they are fed with complete feed and appropriate temperature and humidity. Hanging rubber rings, chains and plastic bottles in the circle for them to play can distract attention and reduce mutual biting.
(6) Pay attention to the indoor air quality, handle the relationship between ventilation and heat preservation, and prevent the occurrence of respiratory diseases.
(7) The pigsty should be thoroughly cleaned and disinfected before and after use, and dried before use.
Piglet feeding management
First of all, feed
Reduce sow feed, reduce breast milk supply and force piglets to eat more suckling pig feed 3 days before weaning. After weaning, keep the original feed (feed the raw material tank 1 week), the original circle (drive the mother to protect the young) and the original nest (change the original nest to the group) unchanged, keep the feed unchanged for two weeks, add appropriate amount of antibiotics and vitamins, supply clean drinking water for piglets, keep the feed clean, prevent mildew, remove leftovers in time, and gradually transition to alleviate weaning stress.
Second, grouping
Strict adoption? All in and all out? The way of feeding. Piglets in the nursery are generally 8 ~ 10 per farm. At the same time, to avoid the behavior of fighting after merger, it is best to use the original nest and turn to the original group to reduce the merger of mixed groups. If it is necessary to mix groups, mix them in equal proportion, and night will not be merged with day.
Third, environmental control.
1. Temperature and humidity. The suitable environment for weaned piglets should be warm in winter and cool in summer, with the temperature controlled at 26 ~ 28℃ and the relative humidity controlled at 65% ~ 75%.
2. Environmental sanitation. The barn must be cleaned 3 ~ 4 times a day and disinfected/kloc-0 times a week. Keep the fence clean and hygienic, strengthen ventilation and keep it dry and clean.
3. Orientation training to form a fixed sleeping, eating and excreting area.
Fourth, the prevention and control of epidemic diseases.
According to local conditions, carry out vaccine immunization against swine fever, erysipelas, pig lung disease, foot-and-mouth disease and streptococcosis. And castrate and expel insects in time.
