Determination of the Factors Affecting Live Weight Gain Using Factor Analysis and Stepwise Regression Model

摘要

To examine the most important factors on weight gains of Brown Swiss (BS) and Holstein Friesian (HF) calves using factor and stepwise regression analyses 53 BS and 41 HF calves were observed from parturition to six months of age. The results showed that physical characteristics, feeding type, gender and breed all played an important role on weight gains of calves.
