Feeding and management of winter sows during pregnancy

As the temperature drops gradually, it is about to enter winter, and for pregnant sows, they not only have to resist the severe cold, but also bear the important task of giving birth to the fetus. The period of low temperature and low light is the period of high incidence of various infectious diseases, so how to do well the management of pregnant sows? Let's take a look.

1. Choose the appropriate feeding method.

Generally, three feeding methods can be adopted for winter pregnant sows, one is to catch two sows in the middle, which is suitable for sows with longer body condition, that is, concentrate is supplemented 20 days before and 10 days after mating, and green feed is the main feed after body condition recovery. until 80 days after pregnancy, concentrate is supplemented. Second, before and after roughing, this method is suitable for sows in good condition before mating, that is, they are fed more roughage during pregnancy and concentrate feeding in the later stage. Third, step by step, this method is suitable for parturient sows and lactation breeding sows, mainly a roughage in the early stage of pregnancy, and then gradually increase the proportion of concentrate, but also correspondingly increase the protein and minerals in the feed.

2. Reasonable feed

In winter pregnancy sow diet, in addition to ensure hygiene and quality, but also need to have a certain green roughage, sows to eat full, but will not oppress the fetus. Amino acids, vitamins and trace elements in green roughage are conducive to fetal growth and development, and adequate drinking water should be given at the same time. It is strictly forbidden to feed moldy, frozen, poisonous and strongly irritating feed, otherwise it is very easy to cause abortion or stillbirth in sows, and do not change the type of feed at will. At 20 days after pregnancy, the fetus is easily affected by the environment, so special care should be given to feed and high-quality full-price feed should be given.

3. Do a good job of protecting the fetus

The focus of winter pregnant sows is to do a good job of fetal protection, and several points should be done in daily management. first of all, the sows should be raised separately to keep the environment of the enclosure clean and hygienic. Sows should eat well, sleep well and exercise less in the last month of pregnancy in order to restore their physical strength and physical strength, but they should do more exercise in the early stage of pregnancy, less exercise in the later period, and stop exercising in the week before pregnancy. Rain and snow weather should also stop exercising, so as not to slip and fall and cause miscarriage.

4. Do a good job of heat preservation

The temperature is very cold in winter, the first thing is to do a good job of heat preservation, to set a special length for sows to ensure that they are warm and dry, the humidity is kept between 60% and 75%, and the temperature is kept at about 22-23 degrees.
