First, the efficacy and function of brown sugar feeding sows
1, emulsion accelerator
When the sow's milk is low, it can be stirred with 200 grams of brown sugar, 5 eggs and 200 grams of white wine. After being stirred evenly, it can be mixed with a small amount of feed and fed to sows at one time, which can improve the milk yield of sows on the same day.
2. aphrodisiac
Prepare 0.5- 1 kg brown sugar, stir-fry in an iron pan, add 1.5-2 kg water to boil, mix with feed, cool, feed it to pigs, and feed it quickly for 3-5 days, so that sows who have not been in estrus for a long time can start estrus.
Step 3 gain weight
Adding 1-3 grams of brown sugar to each kilogram of feed will increase the feed intake of lactating sows and prevent fat loss and emaciation.
Step 3 treat diseases
Brown sugar not only has effects on sows, but also can treat diarrhea of piglets. When piglets have diarrhea due to abdominal cold, 1 kg of brown sugar and 3 slices of ginger can be added to 3 kg of water, and then boiled into soup to feed piglets, which usually takes effect on the same day.
Second, how to raise sows
After the sow is pregnant, the fertilized egg is susceptible to various factors in the early stage of implantation within 9- 13 days, which is the first death peak; The second death summit appeared on the third day after pregnancy, and the number of two deaths accounted for 30%-40% of the total number of fertilized eggs; The third death peak appeared 60-70 days after mating. The feeding of pregnant sows should vary from pig to pig, and the following three methods are generally adopted in production:
1, coarse first and then fine.
It is suitable for multiparous sows who are in good health before breeding, mainly by feeding more green feed in the early pregnancy and adding concentrate in the later period.
2. Grasp both ends and tube in the middle.
It is suitable for multiparous sows with poor constitution. Feed should be increased 20 days before mating and 10 day after mating. After the recovery of physical condition, green feed is the main feeding standard. After 80 days of pregnancy, concentrate should be added. The nutritional level in the later period is higher than that in the earlier period.
Step by step.
Suitable for primiparous sows and lactating sows. In the early pregnancy, green roughage was the main diet, and the ratio of concentrate to feed gradually increased, and the protein and minerals in the feed also increased accordingly. Pay attention to the prenatal 1 week of sows, and reduce the feeding amount by 10%-20%.
