(I) Method of fostering
1. Individual fostering: Sow milk is insufficient, excessive birth, uneven development, can choose strong foster care in the nurse.
2. Fostering the whole nest: Sows lack milk, have poor motherhood, are sickly or sick, or require frequent breeding of sows. They can foster whole-wool piglets.
3. Nesting and fostering: When the two litters have similar maturation periods and the piglets are unequally developed, the piglets are adjusted to the two groups according to their physical strength and body size. The group is composed of many milky and high-quality, well-fed sows. In piglets, the other group of sows is fed a stronger group.
4. Two fostering: The well-developed piglets that are fed with high lactation, high maternal sows, are allowed to nurse or wean off other sows for a period of time, and then feed on other weakly growing piglets.
(B) Precautions and Measures for Fostering
1. The age of the foster piglet should be the same or similar to the nurse's piglet, and should not exceed 3 to 5 days. When the newly-produced piglets are fostered in the first-migration nests, they are required to pick up large-scale foster care for the pigs. When the first-born piglets are fostered in the nests, they must pick up the foster care of the small-bodied piglets; , we must pick a large body and strong foster care, in order to avoid a large difference in weight of piglets, affecting the growth and development of small piglets.
2. The foster sow must be a sow with high lactation, mild temperament, slight body shape, good motherhood, strong disease resistance, large feed intake, and strong nursery performance. Only such sows can feed good piglets.
3. The foster piglets must eat colostrum. It is easy for the piglets to eat enough colostrum to survive. For example, if the piglets do not eat the mother's colostrum, they can eat colostrum (nurs).
4. The scent of the foster piglet is the same as that of the piglet in the foster nest. For fostering purposes, the foster piglets can be applied to the milk or urine of the foster sow (maternal) or they can be placed around the foster sow a few hours later, or they can be swabbed with swabs to wipe the foster sow (maternal). Around the nostrils, it was impossible to identify the foster piglets.
5. Carefully examine the piglets and foster sows (nags) before foster care to prevent infectious diseases and observe the lactation situation. When the foster sow (nurse) puts the milk, the piglet is not only not close to the baby, but instead runs in the opposite direction, trying to flush out the lap and return to the mother's place to feed. In this case, hunger can be used or artificial force can be imposed. breast-feeding.
6. When the piglets are fostered, the operators must not bring in odors, reduce the stress factors as much as possible, and be “quiet, light, fast, accurateâ€.
