摘　　要：经给３４头围产期奶牛口服烟酸和胆碱，试图预防和治疗脂肝病，同时监测受试牛血浆中某些相关生化指标和孕酮含量的变化．结果发现，和对照组比，试验组牛血浆中血糖浓度显著升高的同时，游离肪酸（ＦＦＡ）、谷草转氨酶（ＡＳＴ）和β－羟丁酸脱氢酶的含量显著降低；而白蛋白、总蛋白和镁的含量与对照组比，没有差异．烟酸和胆碱预防组牛中有３０％发生轻度到中度脂肪肝；对照组牛中有５０％发生轻度到重度脂肪肝．在产后５周内，治疗组的脂肪肝患牛恢复率为１００％；对照组牛恢复率为对７１．４％．此外，试验组牛的产奶量、子宫复旧时间。产后首次排时间以分娩到妊娠间隔都分别显著优于其相应对照组．Nicotinic acid(NC) and choline were given orally to the periparturient cows to treat and prevent famy liver in order to improve fertility Several bioob parameters and progesterone were monitored Significantincrease in blood glucose and significant decrease in plasma concentrations of β-hydroxybutyrate,non-esterified fatty acid (NEFA)and aspartate amintransferase (AST)were observed in the treated cows,Howerer,there no significant differences between treated and control cows in tle plasma concentrations of albumin,total protein and magnesium.The incident rate of fatty liver postpartum in the cows with Nc and choline given 2Weeks before calfing was 30%,and the affected cows had a range of mild to moderate fatty liver whilst the incident rate was 50% in the untreated cows.which had a range of mild to severe fatty liver.All treated fatty liver cows recovered within 5 weeks after catving compared with 71 .4% of untreated cows recovered Meanwhile,the treated cows had a significant higher milk production and shorter intervals from calving to uterine involution,to first postpartum ovulation and to conception
