Analysis of the variation of cows' milk energy with lactating curve model in relation to heredity, calving number and calving season



Analysis of the variation of cows' milk energy with lactating curve model in relation to heredity, calving number and calving season



Research Bulletin of the Faculty of Agriculture, Gifu University ( 58): 107-114



This study was performed in order to determine the parameters of the lactation curve, and to determine the effects of dam family line, calving number and birth season on the parameters. Lactation data on 66 Holstein cows raised in the Animal Husbandry Experiment Station, University of Tokyo, Japan, were applied to Wood's mathematical model.
