Many people don't know when to wean piglets, and what is the appropriate weaning age for piglets?

Optimum weaning age for suckling pigs. There is no standard answer to the best weaning age. Early weaning of suckling pigs is a feeding management measure adopted by large-scale feeding mode to improve the average annual litter size of sows and the weaning survival rate of suckling pigs. It is most appropriate to take these two target indicators as the basis for comprehensively measuring the best weaning age of suckling pigs, but it should also be based on the actual situation in the following aspects, otherwise the result of mechanically copying the weaning age may be counterproductive.

Strong correlation factors in weaning period of suckling pigs. The weaning weight of suckling pigs is related to the content of sow feeding management. When the average birth weight reaches a certain standard, the weaning survival rate is high, on the contrary, the weaning survival rate is very low; Suckling pigs need to be fed 5-7 days after birth. The main purpose is to make suckling pigs adapt to feed, get nutrition from feed and avoid stress syndrome when weaning. Feeding management and vaccination during lactation to ensure the good health of suckling pigs; Provide suitable temperature, dry and sanitary environment for suckling pigs; Nursing breeders feed carefully; The milk quality and milk yield of lactating sows reached the peak at 3 weeks, and then kept a gradual decline trend at about 2 weeks.

Why use sow to deliver the bed? Growth performance of suckling pigs after weaning: sows are afraid of heat and suckling pigs are afraid of cold. If there is no relative division in the same environment, it will be difficult to handle this contradiction well. If the temperature of suckling pigs is suitable, sows will experience heat stress. If the sow's temperature is right, the suckling pig will have diarrhea and other health problems because it is too cold. In addition, the delivery bed is lifted off the ground, the bed surface is dry and sanitary, and there is an independent drinking port. Compared with the ground feeding method, it can improve the health status of suckling pigs to the greatest extent, especially reduce the bacterial gastrointestinal diseases of suckling pigs.
