Using the original dairy farm practice as a control, transient ration adjustment and separation of primparousand multiparous cow groups will be employed to improve the health and performance of lactation cows which will be checked by the physiological indicators of ketosis, milk yield and milk composition.乳牛過渡期精準管理dairy cattletransient periodprecision management
