Common problems and solutions of lactation sows

   1, sow fever treatment: prenatal and postpartum sow health status, should be carefully observed, must not be taken lightly, if sow postpartum fever, will endanger the life of the whole litter of piglets. Sow postpartum fever, it is forbidden to use large doses of analgin and other drugs, because this kind of drug inhibition is very strong, after high-dose injection, make the heart overburden, will cause heart failure. Therefore, this kind of drug can cause sphincter spasm, cause breast expansion, can not discharge milk, and finally cause mother and baby.

All dead. You can use traditional methods to reduce fever: take 3000mm to 5000ml warm water, the water temperature is lower than the body temperature, dissolve with a little washing powder, use a gastric catheter to guide people from the rectum, when a large amount of water flows out, you can bring out the heat of the body, with rehydration and other measures can achieve good results.

   2, sow feeding problem: postpartum sows need 5.

More than kg feed can meet the development requirements of piglets and reduce the fat loss of sows. The traditional habit is to add feed from 84 days of late pregnancy, and the feed is pregnant sows. Foreign studies have shown that 84 days of feeding will lead to a decrease in the number of breast cells in parturient sows, affect breast development, decrease milk yield and reduce weaning weight of piglets. The correct feeding time should be 95-100 days in the third trimester of pregnancy. Use "high linoleic acid powder for pigs" or lactation sow feed with grease to meet the needs of rapid fetal development and increase fetal birth weight.

   3. The feed intake of lactating sows is affected by the feeding times of lactating sows: the daily feeding of general pig farms is 2: 3.

Four times a day is the best for lactating sows, especially in the high temperature season, which can increase feed intake by 1 kg per day. In addition, the amount of water consumed by lactating sows significantly affects the feed intake, and the formula is as follows: water intake = 4.2 + 2.52 × feed intake (kg / day). Therefore, the flow rate of the drinking fountain reaches

If the flow rate of the drinking fountain is less than 1.0 liter / s, the sow is likely to drink less than 25 liters of 30 liters per day, and the food intake will be reduced accordingly.

Baking soda 0.6%-0.8% can be added to the diet to increase green feed.

   4. Reduce the number of non-production days:

   (1) days of non-production refers to the number of days in which any sow or reserve pig over the appropriate age (230days) is not pregnant or given birth. Among them, the interval from 3 to 6 days of weaning to mating is the necessary non-production days.

   (2) the days of non-production are caused by the days after 230days of the growth period of reserve sows, the days after weaning to mating, the days of loss of estrus sows, the days of loss of abortion, the days of empty loss, and the days of elimination of death. Non-production days

(NFD) = 365-[average annual litter size x (days of lactation + days of pregnancy)]. If the sow is weaned 28 days, gives birth to 2.3litter per year, and the gestation period is 114days, then the non-productive days (NTD= 365-2.3)

X (11428)] = 39 days.

   (3) measures to reduce the days of non-production: timely breeding of backup sows, breeding as much as possible at the age of 230 days; strengthening the feeding of lactating sows to reduce the interval between weaning and mating; returning sows and inch mating; finding empty sows as early as possible and taking measures to promote estrus; and inch elimination of aged sows.
