Key points of first birth management of reserve sows

The first production management of reserve sows is very important, which has a great impact on the production performance and life span of sows, and the lack of experience and fear in the first production of sows are very important factors affecting the production of sows. So what should be done to make the first parturition of reserve sows effective? Let's take a look.

1. Estrus and supplementary feeding during mating period

The first mating age of reserve sows should be at the age of 8 months and only 110 kg. And do not mate in the first estrus, because this is an underdeveloped ovary. When sows reach the age of 5 months, feed restriction should be carried out, and supplementary feeding should be carried out two weeks before mating, that is, the best feed intake is 40% Mel 50% two weeks before mating, which can increase ovulation. According to the relevant data, the sows can produce two more litters per litter.

2. Moderate nutrition during pregnancy

After the introduction of mating, before the amount of feeding is reduced to supplementary feeding, it is necessary to facilitate egg implantation and reduce embryo death until 84 days of pregnancy, when it is necessary to increase the nutritional level of the diet and increase the proportion of nutrients such as protein, amino acids, calcium and phosphorus. To 2-3 days before delivery, the amount of feed will be reduced to about 1.8 kg, so as to avoid dystocia caused by overnutrition.

3. Fortified food intake during lactation

In the sow 5-7 days after delivery, to gradually increase the amount of feed, the principle is to feed as much as weak pigs can eat, to ensure adequate lactation of sows, enough for piglets to eat. Generally, two feeding methods are adopted, one is on the basis of 1.5 kg per day, the other is on the basis of 2 kg per day, and 0.4 kg for every piglet fed. The total daily feeding amount during lactation should be about 6 kg, preferably more than 6.5 kg. If the feed intake of sows is low, appropriate amount of oil can be added to the feed and protein content can be increased to ensure adequate lactation.
