摘要
目前,奶牛低血钙症多发于经产的高产奶牛,已成为围产期奶牛营养代谢性高发疾病之一.低血钙症奶牛在围产期血钙浓度快速下降,出现跛行、产后瘫痪等症状.奶牛低血钙症会增加酮病、真胃移位、胎衣不下、乳房炎等多种疾病的患病风险,影响奶牛产奶量、生产寿命,增加死淘率,给养殖业造成巨大的经济损失.本文以奶牛低血钙症的发病原因及机制为基础,综述其诊断方法和营养调控措施,旨在为奶牛低血钙症的预防提供参考.
Abstract
Currently,hypocalcaemia in dairy cows is most prevalent in high-yielding cows during parturition,and has become a highly prevalent nutritional and metabolic disease in periparturient dairy cows.Cows with hypocalcaemia experience a rapid decline in their blood calcium concentration during the periparturient period,which can manifest as lameness and postpartum paralysis.The incidence of hypocalcaemia in dairy cows has been linked to an increased risk of developing other diseases,including ketosis,true gastric displacement,foetal clothing inappropriateness,mastitis and a number of other conditions.These in turn have been shown to affect milk production,the productive life of dairy cows,increase the mortality rate and cause significant economic losses to the farming industry.In light of the underlying causes and mechanisms of hypocalcaemia in dairy cows,this paper presents a review of the diagnostic methods and nutritional control measures,with the aim of providing a reference point for the prevention of hypocalcaemia in dairy cows.
