Sutai pig is a new breed of Chinese lean pig bred on the basis of the Taihu pig with the largest number of litters in the world, which maintains the high reproductive performance of the Taihu pig and the advantages of delicious meat and strong adaptability, and hybridizes with foreign boars, with the characteristics of fast growth rate, high lean meat rate, and significant heterosis, and is one of the ideal mothers for the production of lean commercial pigs. So what breed of Su Tai sow is born? What are the key points to pay attention to when raising Sutai sows? Let's take a look!
What breed of Sutai sow is born?
Sutai sows are based on Xiaomeishan, Zhongmeishan, Erhua face and Fengjing pigs as the mother, with Duroc as the father, and bred through crossbreeding. It has the advantages of many litters, high lean meat rate, fast growth rate, tolerance to rough feeding, delicious meat, etc., and is one of the ideal maternal breeds for the production of commercial lean pigs.
Important points to pay attention to when raising Sutai sows
1, it is not easy to raise the old law
Su Tai sow is a new type of lean sow, its feeding method and the old Taihu pig is very different, feeding conditions and nutritional requirements are relatively high, if the past feeding method is easy to cause sows small, poor physique, estrus and other phenomena.
