Un-der the same management conditions, the indexes of Chinese Simmental with aged with birth, 3 , 6 , 12 and 18 month were higher than that of local cattle in the same period. Take the one - year - old cattle as an example, the body height, body length, chest circumference, weight of Simmental crossbreed F1 increased by11 % ,7 % , 1 5 % ,57% respectively compared with local cattle. There is significant difference between them, and the improved offspring showed less disease, rough feeding, suitable for the rural grazing conditions.
