The specific methods for fostering piglets are as follows: Fostering: Sows need no milk, sickness, sickness, postpartum death, biting, etc.; or sows need frequent breeding. When sows have fewer litters and are eliminated in advance, the whole litter needs to be fostered. . Nesting and fostering: When the maturities of the two sows are similar and the piglets are of uneven size, the piglets are divided into two groups according to their strength and size, and the sows with high milk and high quality and good maternal feedings have weaker constitutions. In group piglets, the other sow has a stronger group of constitutions. Two fostering: Early weaning of piglets with high lactation power and good maternal status or selection of weaned sows to choose to suck other weak constitutional piglets or other superfluous newborn piglets that have consumed colostrum. When fostering piglets, generally follow the following principles: 1. Entrust piglets to eat enough colostrum as soon as possible. Colostrum contains a large amount of maternal antibodies in the first few days after sow production, and then the number of maternal antibodies quickly declines. When piglets are born, the intestinal epithelium is in the original state, with the absorption of macromolecular immunoglobulins, ie, the mother With the function of the source antibody, the ability to absorb maternal antibodies began to decline after 6 hours. Since there is no innate immunity at birth, maternal antibodies are critical for early disease resistance in piglets and are important for improving the survival rate of piglets. Piglets can acquire strong immunity only if they receive enough colostrum in time. Fostering is generally conducted within 96 hours of birth. The sowing date of the foster sow is as close as possible. Usually the difference between sows' production date does not exceed one day. 2. When the post-produced piglets are fostered in the first-migration nests, they are required to pick up the foster care of the pigs. When the pre-produced piglets are fostered in the nests, the foster piglets will be fostered with a small weight; the piglets produced at the same time When fostering, it is necessary to adopt a large size and strong foster care in order to avoid large differences in the weight of the piglets and affect the growth and development of piglets with small body weight. 3. Usually the strongest piglet in the nest, but the modern sow has a smaller or slender teat, a high milking power, and a small piglet that can house weak piglets. 4. When fostering, it is necessary to estimate the nursing ability of the sow: that is, to consider whether the sow has a sufficient number of effective teats, estimate its maternal behavior, and lactation ability. 5. Use the suckling behavior of piglets to guide fostering: Piglets that have been born for more than 8 hours and have not established a fixed teat sequence are the first choices for foster care. If a small piglet has a fixed nipple position in a large nest, it is best to leave it behind the original sow. 6. Fostering weak piglets in the early farrowing litter: Individual litters in the litter of the litter of the first litter will be relatively weak. These individual piglets can be fostered into the litter of the newborn sow. However, it is important to ensure that these foster piglets match the weight and vitality of the piglets in the pen. 7. The best choice for fostering is to select sows on the same parity. Or the offspring of young sows choose young sows on behalf of the raising, the offspring of the old sow, choose to replace the old sow. 8. Piglets should minimize foster care to prevent cross-infection of the disease; it is generally forbidden to foster sick piglets to prevent the spread of disease. 9. Spread the urine of the foster sow on the foster piglets, or sprinkle a liquid of the same smell on the whole group of piglets (such as risol, etc.) to mask the odor of the piglet and reduce the sow's rejection of the foster piglet. 10. In the breeding farms, piglets need to be marked and recorded before they are fostered to avoid pedigrees. Whether or not the newborn piglet is fostered, the work of fixing the nipple must be done. Fixing the nipples can reduce piglets' fight and fight for milk and ensure that they can eat colostrum early enough, which is a good way to achieve balanced development of piglets. The fixed nipples should be adjusted according to the wishes of the piglets. Generally, the weak piglets are fixed on the first two pairs of nipples. The piglets with strong constitution are fixed on the posterior nipples, and other piglets do not have to fight for the same nipple. In short, foster care should be adapted to local conditions and be flexible in order to improve the survival rate and economic efficiency of piglets as the ultimate goal.

Individual fostering: Sow lactation is insufficient, there are too many litter size, piglets are not uniform in size, and strong foster fosters can be selected.
