see more details in scaled farm was optimized by CPM model, and the effects of optimized diets on growth, development and blood biochemical parameters were evaluated in this study. Forty Holstein replacement heifers with the same months of age (7 months of age), and similar body height and weight were randomly divided into control and test groups according to paired experimental design, and each group had 20 heifers. Heifers of control group were fed original diets of the farm, while those of test group were fed diets optimized by CPM model. The experimental period was 270 days. The results showed as follows: replacement heifers fed optimized diets had significantly higher cannon circumference at 8, 10, 11, 13 and 15 months of age (
P<0.01); serum

see more details content of replacement heifers fed optimized diets was significantly higher than that of heifers fed original diets (
P<0.05); cost of optimized diets of 7 months of age, 8 to 9 months of age, 10 to 12 months of age, 13 to 15 months of age was decreased by 1.02, 0.78, 0.62 and 0.52 yuan/(head.d) than that of original diets, respectively. In conclusion, diets optimized by CPM model can increase cannon circumference of Holstein replacement heifers, improve growth and absorption of blood calcium, and decrease feeding cost; CPM model can be used to evaluate and optimize diets formulation of Holstein replacement heifers.
