ABSTRACT

The present study surveyed that the prevalence of subclinical and clinical ketosis in cattle was assessed in and around Bikaner; a total of 200 cows after parturition were examined. The overall prevalence of clinical ketosis amongst post-parturient cows was 11.50%, while 23.50% for subclinical ketosis. Prevalence of clinical and subclinical ketosis in cows with relation to breed was the highest in Holstein Friesian crossbred cows (17.58%), while the lowest in Rathi cows (05%). Prevalence in relation to the age was the highest in 8–9 years of age (13.79% and 29.31%) and the lowest in >9 years of age (4.76% and 9.52%). Prevalence in relation to number of lactation/calving was the highest in fourth lactation (14.29% and 30.36%) and the lowest in first lactation (2.86% and 11.43%). Out of 11.50% cases of clinical ketosis, the highest prevalence was recorded (30.43%) during 8–14 days of lactation; similarly, out of 23.50% cases of subclinical ketosis, the highest prevalence was recorded (29.79%) during 8–14 days of lactation. Month-wise prevalence of clinical and subclinical ketosis was the highest in December that is 26.09% and 23.40%, while the lowest in August 4.35% and 2.13%.

摘要

本研究调查了在比卡内尔及其周边地区评估牛亚临床和临床酮症的患病率；共检查了200头分娩后的奶牛。产后奶牛临床酮症的总体患病率为 11.50%，而亚临床酮症的患病率为 23.50%。与品种相关的奶牛临床和亚临床酮症的患病率在荷斯坦弗里西亚杂交奶牛中最高（17.58%），而在 Rathi 奶牛中最低（05%）。与年龄相关的患病率在 8-9 岁时最高（13.79% 和 29.31%），在 >9 岁时最低（4.76% 和 9.52%）。与泌乳/产犊数相关的患病率在第四个泌乳期最高（14.29% 和 30.36%），在第一个泌乳期最低（2.86% 和 11.43%）。在 11.50% 的临床酮症病例中，哺乳期 8-14 天的患病率最高（30.43%）；同样，在 23.50% 的亚临床酮症病例中，哺乳期 8-14 天的患病率最高（29.79%）。12月份临床和亚临床酮症的月患病率最高，分别为26.09%和23.40%，而8月份最低，分别为4.35%和2.13%。
