Effect of Body Condition Score and Locomotion Score on the Production Performance in Dairy Cows
摘要
Abstract
To investigate the influence of body condition score (BCS) and locomotion score (LS) on the milk yield performance in dairy cows,data of 5000 cows on 7 dairy farms in Beijing area during July and August 2016 was collected.The effects of farm,parity,lactation stage,BCS and LS on milk yield,somatic cell count (SCC) and milk components were analyzed by linear model using SAS,so did the factors affecting BCS and LS.Results showed that the effects of the BCS and LS on the daily milk yield were both highly significant (P＜0.01),and the effect of the BCS on the protein percent was significant (P＜0.05).Parity had significant effect (P＜0.01) on LS,however,no effect on BCS,The effect of farm-scorer on BCS and LS was highly significant (P＜0.01),so did lactation stage.The regression relationship between LS and BCS was significant,and the cows with higher LS tends to have lower BCS.In practice,the BCS and LS can be used to strengthen dairy management,improve the milk yield and milk quality,and achieve great economic benefits.关键词
