泌乳期奶牛尿液酸碱度与疾病的相关性分析
Correlation analysis of urine pH and disease in dairy cows during lactation
摘要
Abstract
In this experiment,601 urine samples collected from 257 lactating cows in an intensive farm were used to explore the effect of urine pH on lactation,incidence of diseases and culled rate,and to evaluate the baking soda action.Results showed that the incidence of disease was 83.33％ in cows with acid urine,72.72％ with alkaline urine,and 18.18％ with neutral urine.Acid urine negatively correlated with rumen acidosis,abomasum displacement,forestomach atony/ rumen tympanosis,ketosis,interdigitalis dermatitis / laminitis;and alkaline urine positively correlated with mastitis.The culled rate was 26％ for the very acid group,18％ for the alkali group,0 for the acid group and 5％ for the neutral group.And the abnormal urine pH could be more effectively controlled in lactating cows fed 0.26 kg of baking soda per day per cow than 0.19 kg per day per cow.Therefore,the addition of baking soda could reduce the incidence of diseases,decrease the cullted rate,and bring economic benefit to the graziers.关键词
