Feeding Management of Lactating Pigs

The feeding and management of suckling piglets is mainly to grasp the three foods (dairy food, starting food, strong food) and go through the three hurdles (newborn pass, feeding pass, weaning pass).

1. do a good job of dairy food and pass the newborn pass.

(1) carry out care and delivery, do a good job of delivery, prevent piglets from being crushed, frozen to death or die in childbirth, and reduce the mortality of piglets.

(2) to rescue "fake dead piglets" in time, artificial respiration can be carried out or "fake dead pigs" can be soaked in 35-40 ℃ warm water with their heads out of the water or smeared with iodine tincture, alcohol or ammonia on their nostrils for drug stimulation.

(3) cut canine teeth and tail within 24 hours of birth to prevent nipple bite, tail bite and mutual bite of sows, affecting the safety of breastfeeding and pigs.

(4) fix nipple and eat enough colostrum as soon as possible. Colostrum contains high immunoglobulin and magnesium salt, which can make piglets produce immune antibodies, expel meconium and improve disease resistance. Generally, each piglet should be given enough colostrum 2 hours after birth (no more than 24 hours at the latest). Piglets have the habit of eating fixed nipples. In order to make litter piglets uniform and strong and improve the survival rate, artificial nipple fixation should be carried out 2-3 days after birth.

(5) strengthen heat preservation, anti-freezing and anti-pressure. The optimum temperature of piglets was 30-32 ℃ at 1-3 days old, 28-30 ℃ at 4-10 days old and 26-28 ℃ at 11-30 days old. In general, infrared lights are used for heat preservation, and the main anti-pressure measures are to keep sows quiet and set up protective rails or boxes.

(6) to prevent the disease from the mouth into the piglets within 3 days of birth, scrub and massage the sows' breasts with 0.01% potassium permanganate warm water solution before each feeding, one to prevent sow mastitis, and the other to prevent piglets from yellow and white dysentery.

2. Grasp the food and get through the replenishment level.

(1) Iron supplementation in time to prevent anemia is generally given 100-200 mg iron per piglet within 3 days of birth; for fast-growing piglets, a second injection should be considered before weaning.

(2) within 3 days of birth and during weaning, 0.1% sodium selenite solution 0.5-1.0 ml was injected into each piglet in time to prevent stiff piglets and post-weaning piglets from edema disease and white muscle disease.

(3) timely rehydration after 3-5 days of age, piglets can set up a drinking tank in the supplementary feeding room to supply clean drinking water and slightly sweetener to prevent piglets from drinking dirty water or urine when they are thirsty, causing dysentery.

(4) the main purpose of timely and early feeding is to promote the gastrointestinal development of piglets, relieve the itching of piglets' gums and reduce the stress of feeding after weaning. Generally, the feeding begins at the age of 7 days. The method is to sprinkle a little suckling pig pellet on the dry and clean board (for example, Dabinong 551, etc.) and let it be forced to eat for 3-4 days. When the piglets begin to feed on suckling pig feed, the feed trough can be used. When replenishing materials, add as little as possible, generally feed 5-6 times a day to prevent feed waste; discard the rest every day, and then use the trough after cleaning and disinfection.

3. Pay attention to the strong food, increase the weaning litter weight and pass the weaning pass.

Sow lactation reached its peak at 3 weeks, and then decreased gradually, when breast milk alone could not fully meet the needs of rapid growth of piglets. Piglets can fully feed on suckling pigs after 10-15 days of feeding, so we must make use of this favorable opportunity to encourage piglets to eat a large amount of food, so as to make up for the shortage of breast milk, promote rapid production of piglets, increase weaning litter weight and reduce weaning stress.

(1) choose suckling pig feed with high nutrient concentration and good balance, palatability and digestibility.

(2) feed less frequently to adapt to gastrointestinal function and increase food intake.

(3) when weaning, avoid stress factors such as vaccination, group conversion and castration, so as to reduce weaning stress.

(4) 2-3 days before weaning, reduce the amount of feed and drinking water of sows, reduce the amount of lactation of piglets, promote more food intake of piglets, reduce weaning stress, and reduce the incidence of sow mastitis.
