Sows are dominated by small-scale, semi-intensive feeding and management methods. Some pig farmers have had improper sow rearing and management methods, resulting in unnecessary elimination of sows, which directly affects the economic benefits of raising pigs.

First, record off

According to the sow's age, parity, lyrics, medical records, and epidemic prevention time, master the sow's body condition changes, observe the sow's estrus performance, and timely breeding. During the pregnancy of the sow, different feeding measures are taken to ensure the normal sow of the sow, and the time of entering the delivery room is decided according to the sow breeding records.

Second, prenatal feeding off

In the early perinatal period of sows, the dietary standard is protein 10%-13%, protein concentration should not be too high, energy is controlled at 3.0-3.2 Mcal/kg, calcium-to-phosphorus ratio is 1.8:1, daily intake is controlled at 1.8 Below kilograms, feed intake is controlled at 1.5 kg within 1-2 days before delivery. A small amount of multi-dimensional electrolytes may be added to the water to supplement the malnutrition caused by insufficient intake, or replaced by green feed. Strictly controlling the feed intake of salt and high protein diets before birth to effectively prevent the occurrence of postpartum mastitis and anoxia in sows.

Third, nursing care

The sows were washed prenatally with a less irritating disinfectant or 0.5% potassium permanganate to cleanse the breasts and vulva. When piglets are born, farrowing sows cannot be stimulated and scared. Born piglets are responsible for the separation and disinfection of the umbilical cord to prevent piglet infection. Piglets born within 6 hours must have colostrum, and within 8 hours the sows have not been produced and must undergo oxytocin treatment.

Fourth, health care

The postpartum and postnatal nursing sow of the sow had done a postpartum health care job for 3 days after the delivery. Observed the sow's uterine involution and found that there was an abnormal phenomenon, timely anti-inflammatory treatment was required. The piglets supplemented iron within 3 days, selenium supplemented 7 days, and went to dog teeth at the same time.

Fifth, postpartum feeding

Sows were fed bran brown sugar water within 3 days after delivery. Do not overfeed and milk according to the amount of milk or piglets. Gradually increase the total amount of feed every day after the 5th day and carry out an investigation. After 20 days, add 3% of the weight of the sow. The weight of piglets ranges from 1% to 1.5% of the total body weight.

Sixth, open food off

Piglets are artificially baited 5 to 7 days after birth to encourage the piglets to feed as early as possible to stimulate gastrointestinal development. At the same time, the changes in the sows' breasts should be observed and the breasts should be well maintained.

VII. Epidemic prevention

Piglets can be epidemic-proof after 20 days, and the epidemic prevention program should be based on the history of the local epidemic.

Eight, weaning off

25-30 days sows are prepared for weaning, gradually reducing sows' feed intake, starting to reduce the number of feedings first, and then reducing the number of feedings, controlling drinking water, reducing the number of feedings, increasing the feed intake of piglets, and increasing the feed intake of piglets. When we reach 150-200 grams per day, weaning can be performed, sows should be carefully observed in the early weaning period to prevent sows from mastitis due to weaning, or self-mutilation caused by crossing the fence.
