摘　　要：[Objectives]This study was conducted to study the effects of cows'milk quality on suckling calves'growth and development.[Methods]A total of 80 regular milk samples from Simmental and Angus cows were collected to complete the detection of conventional milk components.[Results]Under the same feeding and management conditions,the chemical composition of Simmental cows'milk was better than that of Angus cows'milk.High milk fat in Simmental cows'milk was beneficial to calves'early growth and development,and high milk protein in Angus cows'milk composition was conducive to calves'early weight gain.[Conclusions]This study provides a theoretical basis for reducing calves'mortality,alleviating calves'stress,and improving the economic benefits of beef cattle breeding.
