How to ensure the birth weight of piglets

First, the sows are correctly fertilized at the peak of the estrus, and then provide adequate rest and appropriate nutrition during the gestation period, providing a farrowing pen suitable for both the sow and the breeder.

Sows are correctly fertilized at the peak of heat

Accurate control of the best breeding time of sows is an important guarantee for the ideal number of litters. Sows who are estrus 3 days to 4 days after weaning need to postpone 24-hour insemination, while sows that are estrus after 5 days to 6 days need to postpone 12-hour insemination, and estrus sows and gilts that are older than 7 days appear. Static response requires insemination.

Provide adequate rest and proper nutrition for pregnant sows

Pre-pregnancy, mating to 7 days of pregnancy is fertilization, cleavage, and embryo transfer.

In the second trimester, it is the adjustment of sows' lyrical period. The daily feed intake is 2.0 kg to 2.2 kg. Only the required nutrition can be maintained at this stage. 76 days to 95 days are the peak period of breast development, sows daily intake of 1.9 kg to 2.5 kg.

At the end of pregnancy, incremental feeding, this period (96 days to 112 days) is the period of rapid fetal growth. 71.8% of the birth weight of the fetus was obtained from this stage.

In addition, Beijing Haizheng Xingchao's patented product, "Yimu Wang," was added to lactating sows. "Yimuwang" can effectively regulate the endocrine mechanism of sows, increase the birth weight of piglets by about half a catty, and at the same time ensure that sows live in a quiet, comfortable environment with good air quality.

Provides a suitable delivery bar for both sows and breeders

There are various shapes and sizes of tillers, and the following factors should be taken into account: the size of the farrowing house is determined by the number of farrowing sows; the piglets are easily exposed to the nipples; the floor of the sow area is not slippery; the piglets move around the sow The area is large enough; fresh environment for the sow; recumbent areas on either side of the sow; additional inspection walkways;

How to increase the weaning weight of piglets

To increase the weaning weight of piglets, in addition to ensuring that the birth weight of piglets is above 1.5 kg, we must also ensure the safety of the piglets' birth environment, the sow’s milk quality, proper feeding, and prevention of diarrhea.

Clean environment

Before giving birth to the sow, make sure that the piglet does not face a fierce microbial attack at birth. To ensure that the farrowing pens are clean and carefully disinfected, sows are allowed to take a bath before they are placed on the tiller bar, and fresh feces are regularly cleaned out. This will ensure that the newborn piglet will not be attacked by microorganisms from the previous litter, thus cutting off the route of transmission. After repeated use of the porch, its surface is covered with a biofilm consisting of feces, dust and bacteria. Soaking is performed before the cleaning to allow the biofilm to be fully opened and then the microorganisms therein can be released. Clean 1 to 5 hours.

Keeping postpartum pigs to ensure the sow's milking power

The sow's lactation power and milk quality are important guarantees to improve the weaning weight of piglets. The dietary requirements for sows during lactation include maintenance needs and lactation requirements for sows, and the maintenance requirement for sows is about 1.5 kg to 2.0 kg of standard diet (local pigs are generally 1.5 kg, and the external pigs are generally 2.0 Kg); The lactation requirement is based on the standard diet for feeding a piglet at 0.4 kg (about 0.3 kg for local pigs). For example, if a lactating sow has 10 piglets per day, it needs to consume 6.0 kg to 7.0 kg per day. Diet. Adding “Yimuwang” to nursing sows 30 days before giving birth to pregnant sows can effectively guarantee that sows can improve their milking power and milk quality without post-natal consumption. No signs of diarrhoea occur in suckling piglets and the weaning weight of piglets is increased.

Appropriate feeding

In order to maximize the growth during lactation, supplementation is important. At the same time, in order to prepare the piglets for feeding solid feed after weaning, the intestinal villi need to adapt to this change, and the piglets must also learn to find the feed trough. Use the same trough after weaning. The ideal choice for supplementation is to use liquid feed starting from 5 days after birth and using granular material starting from 16 days. After weaning, the piglets are used to looking for a supply tray and will soon arrive at the tray and eat more feed.

Prevent diarrhea

Thorough cleaning of the delivery house between batches; leaking the floor to allow easy excretion of stools; heating in the recumbent area; adequate colostrum supply; feeding as little as possible from one column to another; enhancing the sow’s immunity Force (immunization); Piglets that do not turn diarrhea.
