First, the daily management of lactating sows

Lactating sows should be kept in a single column. When the weather is fine, the sows can take piglets to the vicinity of the pig house for free for 20 to 30 minutes after 4 to 5 days of postpartum. The lactating sow house should be hygienic, dry, quiet, fresh air and suitable temperature and humidity. The minimum temperature in the winter delivery room should be above 10 °C. The lactating sow house should be cleaned once a day or every other day, and disinfected once every 5 to 6 days with no disinfection. A few days after delivery, the piglets should be manually assisted to fix the nipples. Some primiparous sows may have breast-feeding stress and refuse to breastfeed. At this time, artificial induction is required. Gently stroke the sow's belly or massage the breasts while breastfeeding, so that it can be breast-feeding comfortably. After a few days, it will not refuse breastfeeding.

2. Feeding of lactating sows

The lactating sows are fed with wet materials, and the ratio of feed water to water is 1: (0.6-0.7), which is fed 3 to 4 times a day, and the total daily intake should not be less than 1 hour. The sows should not be fed too much after delivery. The feeding amount should be gradually increased after 3 to 5 days, and the feeding amount can be increased to the normal amount one week after the birth. Large pig farms with good conditions are mostly weaned at around 30 days old. The sows can feed 5 kg of concentrate per day for 10 to 20 days after delivery, and 5.5 to 6.0 kg of concentrate for 20-30 days after delivery. 30 to 35 days, the daily feeding amount will gradually drop to 4.5 to 5.0 kg. In small and medium-sized pig farms, piglets are weaned at 50 days of age. The sows should increase the amount of daily concentrate feed 40 days before delivery, and gradually reduce the amount of daily concentrate after 40 days. For sows with less than 8 piglets, the amount of feed should be properly controlled. For sows 2 to 3 days before weaning, the amount of feeding should be gradually reduced to prevent mastitis. The feeding time of lactating sows should be fixed, not early and late. Several feed formulas for lactating sows are now available for reference.

1. Corn 30%, barley 25%, cottonseed cake 18%, secondary powder 10%, bran 8%, rice bran 2.5%, wheat 2.5%, blood meal 2%, bone meal 1%, salt 0.5%, calcium powder 0.5%;

Third, the method of increasing the amount of milk

Lactating sows are best fed with special full-price ingredients, or they can feed a comprehensive, balanced, and palatable mixture. When the protein content of the feed is insufficient, the fish meal may be appropriately supplemented. It is necessary to pay attention to the feeding of green fodder, and it is better to feed the concentrate and the green fodder every day at a ratio of 1:1. If the green fodder can be broken or beaten and mixed with the concentrate, it is best to feed. The type of feed that the sows are fed during lactation should be stable and should not be changed at will. Sows with good breast development and good sensation should gradually reduce the amount of feeding (from 1/3 to 1/2 of the late pregnancy) 3 to 5 days before delivery, and suspend the feeding of green fodder to prevent postpartum causes of sows. Mastitis is caused by excessive or excessive lactation. Over-fertilized sows should gradually reduce the amount of feed they feed 10 days before delivery. Sows with poor breast development and poor sensation should be fed prenatally. The sows should return the feed to a constant 5 to 7 days after delivery.

When the sow has anorexia, the sow should be rushed to the outside of the house for 40 minutes to an hour each day. The number of days can be relieved or basically relieved. Sows should maintain a clean, dry, quiet and fresh air during lactation.
