How to scientifically manage low parity sows from nine aspects
1. Feed the feed correctly. After the gilts have been mated, special gestation sows (low parity gilts for special feeds) should be used. The common practice in China is to use common gestation feeds for gilts after mating, and the low parity physiology is in a special period of time. The intake of nutrients not only meets the requirements for the growth and development of the fetus, but also meets their own growth and development. Therefore, it is not enough to ingest the nutrition of the universal pregnancy feed, resulting in insufficient nutrition or imbalance, resulting in excessive consumption of sows during lactation. Nutrition in the body meets lactation, which in turn causes lassitude after weaning. The correct course of action is to use dedicated feeds for both sows less than 2 fetuses, both during pregnancy and during lactation. It should be noted that if the feeds are processed on-site, close attention must be paid to changes in nutrients and bulk density of the feed ingredients. The origin, variety, and growth period of raw materials vary greatly in nutrient composition, and this difference is usually above 5%. 2, the amount of feeding within 30 days after breeding should not be too much. Different breeds/strains are different, usually between 2.0 and 2.4 kg/day. Landraces have larger white feeds of about 5-10%. Eating too much feed will increase embryo loss and lead to fewer litters. . 3, 70-90 days of pregnancy can not be improved through sow feed sows better. Pregnancy 70-90 days is the sow's breast development period. No matter how the sow's weight and body condition is, it should not improve the sow's sorrow through the increase of feed. It is recommended that the maximum feeding amount should not exceed 2.6 kg/day: conditional Boars can use boars to stimulate sows to be bred twice a day for not less than 10 minutes each time. Attention should be paid to each boar for up to 5 sows at the same time. 4, to ensure adequate clean drinking water. From the 90th day of gestation to the end of lactation, it is best to use a combination of artificial water and free drinking water during feeding. This can reduce the occurrence of constipation in sows, and can also provide sow feed intake during lactation, thereby increasing sow lactation. performance. 5, free to eat. After sow weaning, we continue to use lactating sows or special sows for low parity sows and eat freely. 6, teaching slot material selection and use. The scientific use of slotted materials can maximize the protection of sows. This is especially true for high yields. Sows are particularly important. 7, the correct use of drugs and vaccines. Try not to use antibiotics (except for de-worming drugs) during the perinatal period. Always remember that health care is not equal to drug abuse. 8, the appropriate density. For captive sows, the appropriate density is important, with 2.0-2.5 square meters per sow being the best. 9. There are two criteria for the first breeding time of gilts, either of which is optional: A, 230 days or more B, third estrus and breeding.
