Piglets have fast growth and vigorous metabolism, especially protein metabolism and calcium and phosphorus metabolism are much higher than those of adult pigs. At the age of 20 days after birth, the protein per kilogram of body weight is 30 ~ 35 times that of adult pigs.
The net metabolic energy per kilogram of body weight is three times that of adult pigs. Therefore, piglets have a high demand for nutrition, both in quantity and quality, and are particularly sensitive to malnourished feed.
Extended data:
Piglet insulation Because newborn piglets have thin subcutaneous fat and weak cold resistance, it is necessary to strengthen insulation. The temperature of 1-3 days old is 30-32℃; The temperature of 4-7 days old is 28-30℃; The temperature of 8-30 days old is 22-26℃.
The main measure of piglet heat preservation is to build a small greenhouse with an area of 1 m2 and a height of 80-90 cm in one corner of the sow pen, leaving a small door for piglets to enter and leave freely, and the roof and surrounding areas are covered tightly with grass, and the indoor area is high with soft grass mats.
