Physiological condition and nursing of piglets

There are differences between piglets in the mother and the outside world. Generally, pig farms will be equipped with pig breeding equipment to provide nutrition and care for sows during pregnancy. In the mother's body, it depends on the mother's blood to supply nutrition and oxygen, and then takes away the waste; after birth, it depends on its own respiratory system and blood circulation system to supply oxygen and nutrients, and obtains nutrition through its own feeding. It is a sterile environment in the mother and is threatened by various microorganisms after birth. The temperature is constant in the mother's body, and it can be adjusted by itself after birth.
1. Postnatal physiology
(1) fast growth and metabolism.
(2) the digestive system is underdeveloped and the digestive function is not sound.
(3) the function of thermoregulation is not perfect, and the ability of cold stress is poor.
(4) lack of immunity, easy to die (having immunity ability only after eating colostrum, the immunoglobulin is blue and yellow after 4 weeks of age, prone to diarrhea, which is the most critical immune period).
2. Nursing of newborn piglets
(1) fix the nipple and eat enough Colostrum (the piglets must be allowed to eat colostrum within 2-3 hours after birth, and form the habit of sucking milk with fixed nipple. Within 2-3 days, fix the nipple manually to make the piglets eat delicious colostrum).
(2) keep warm to prevent freezing.
(3) strengthen management to prevent crushing.
(4) according to the actual situation, foster and nest together, the principle is: the birth date should be similar, preferably not less than 3 days before and after, and the weight size should be relatively consistent, so as not to lead to uneven development of big bully small; it is better to eat the colostrum of sows or the colostrum of foster sows, otherwise the survival rate is low; The milk or nest should be smeared with the same odor on the body of the piglets; when the piglets are hungry, the mentality of hunger is used to accelerate the recognition of sows.
