The main point of managing sows is to maintain a reasonable body condition and ensure adequate supply of trace elements and vitamins.
After sow weaning, the sows are still fed feeding material until estrus. The amount of feeding is good. At the same time, the boars are bred and checked three times a day after weaning, and Duroc boars are preferred.
Immediately after mating, they should be replaced with feed for pregnant sows, and the amount of feeding is about 2 kg. This amount is maintained until 25 days after mating, and the individual's specific feeding amount is determined according to the sow's body condition. The lean sows can be added to 2.25-2.5 kg, medium and partial body weight to maintain the original amount.
After 18 to 24 days of mating, a second visit is required to enable the re-stocking of the returning sow to be timely.
After 36 to 44 days of mating, a third visit is required to enable the gilts to be reassigned in time. Why should the third visit be made at this time? The reason is: if the sow is weaned and If the time is too early or too late, the resulting fertilized egg develops into a weaker embryo. Although the embryo is weak when performing the second check, it is not dead and still alive, but because it is weak, it may be 20 - Death in about 30 days, absorbed by the uterus, not immediately after the absorption of estrus, over a period of time will heat again, the general estrus time is the second estrus cycle after mating. Pig farmers often check the first estrus cycle after mating, and they usually check again for 80 to 100 days (4th or 5th estrus cycle after mating) because at this time they find that the sow's belly has no drums. stand up.
After 90 days of mating, the feed is replaced with feed sows. The amount of feed varies according to the body condition of the pregnant sow and the size of the abdomen ranging from 3 to 5 kg. Because the sows have already produced piglets, the birth canal is generally loose. Therefore, the larger piglets can also be produced. During this time, the crucial period for determining the birth weight of the piglet is to make the piglet have a significant new birth. Then, the feed amount must be kept up during this time.
The amount of feeding is 2.5 to 3 kilograms before the first day of labor. It is not necessary to reduce the amount of prefeeding for 7 days, and the amount of feeding cannot be reduced too much. Otherwise, the calf's calving process will be delayed due to lack of energy and it will be easy to lick. Dead pig.
Feeding during the lactation phase is the same as feeding the gilts during the lactation phase, so that the sows feed as much feed as possible so that the weaning weight of the pigs is greater.
