Abstract

OBJECTIVE

This study aimed to comparatively determine the prevalence of trichostrongylid nematodes and egg excretions in cows that are in the periparturient period (PPP) and pregnant cows in the non-periparturient period (NPPP).

METHODS

Animal materials are constituted by cows in PPP and NPPP in 10 ranches in Kars and surrounding areas. Stool samples were collected from the rectum of 125 pregnant cows, which were in NPPP during November 2010 - January 2011 and from the same cows in PPP during April-May 2011. Stool samples were analyzed for the presence of nematode eggs by the flotation method. EPG was determined by the McMaster method.

RESULTS

Trichostrongylid nematode eggs were detected in seven of 10 dairy cattle ranches (70%). The prevalence rates of trichostrongylid nematodes were 16.8% (21/125) during NPPP and 27.2% (34/125) during PPP. Nineteen of 21 (90.5%) positive samples during NPPP were positive during PPP. Fifteen negative samples during NPPP were positive during PPP with respect to trichostrongylid nematode eggs. The egg count of trichostrongylid during PPP (total, 4350; mean, 34.8; n, 125) was greater than that during NPPP (total, 1250; mean, 10; n, 125).

CONCLUSION

Cows had nematode eggs during PPP and played an important role in transmission.

摘要

目的

本研究旨在比较围产期（PPP）奶牛和非围产期（NPPP）怀孕奶牛体内毛圆线虫的感染率及虫卵排泄情况。

方法

动物材料由卡尔斯及其周边地区10个牧场的PPP和NPPP奶牛组成。于2010年11月至2011年1月收集125头处于NPPP的怀孕奶牛直肠粪便样本，并于2011年4月至5月收集同一批奶牛处于PPP时的粪便样本。采用漂浮法分析粪便样本中是否存在线虫卵。通过麦克马斯特法测定每克粪便虫卵数（EPG）。

结果

在10个奶牛场中的7个（70%）检测到毛圆线虫卵。NPPP期间毛圆线虫的感染率为16.8%（21/125），PPP期间为27.2%（34/125）。NPPP期间21个阳性样本中的19个（90.5%）在PPP期间仍为阳性。NPPP期间15个阴性样本在PPP期间毛圆线虫卵检测呈阳性。PPP期间毛圆线虫的虫卵计数（总数4350；平均值34.8；样本数125）高于NPPP期间（总数1250；平均值10；样本数125）。
