(a) raising sows
1, sow breeding preparation period. The main criterion for a good sow is to be able to estrus in time and maintain normal ovulation capacity. To achieve such a standard, it is best to keep them in good condition, not too fat or too thin. If the sows are too thin, concentrates and green fodder can be appropriately increased to prompt them to ascend, rejuvenate, and escalate as soon as possible. If the sow is too fat, it will win to reduce the amount of concentrate feed, increase the amount of green roughage, and increase its exercise capacity to promote it to fall out, which will help improve the rate of quasi-fetal birth.
2. Pregnancy sow rearing. In the early stage, the raw food was mainly green, but the feed quality was better. Especially when you are pregnant for about 20 days, you must strengthen feeding. Carefully select the feed and do not mold, otherwise it will cause early death of pigs. In late pregnancy, especially in the last month of pregnancy, the piglet develops rapidly. It is necessary to appropriately increase the amount of concentrate feed for sows, especially the feed containing more protein, so as to ensure that the sow gets enough nutrients, which is conducive to piglet development and later stages. Lactating. Sow constipation occurs during this period and can be treated with sow 8037.
Sows feeding during lactation. The task of raising lactating sows is to try to increase the amount of sows in the sow. At this time, in order for the sow to secrete more and better milk, and to ensure the health of the sow, we must properly feed more soy cakes, bran, legume grass and other feeds containing more protein.
(B) timely identification of sows estrus, so that timely breeding
In order to obtain more robust piglets, prevent the sows from empty, it is very important to identify the estrus of the sow timely and accurately, and to achieve timely breeding. Soma estrus identification is common to farmers and is not described here. One of the key points here is to determine the estrus, and how to go for breeding: First, using the compounding method is to use the same boar twice in the estrus cycle of the sow, and the intermediate interval is 10 to 12 hours. This breeding method can improve Sow conception rate. The other is to seize the first estrus breeding of sows after weaning. The sows are in estrus 5-7 days after weaning. This estrus period is relatively easy to master, and the quasi-fetal rate is also high.
(C) Care for piglets
To improve the survival rate of piglets, pigs must be cared for. Care of piglets is mainly to prevent piglets diarrhea, do a good job of protection against heat, do a good job of sow care, do not let sows squeezing piglets, after weaning feed with fine material, do a good job of vaccine epidemic prevention.
