Abstract

Gastrointestinal nematodes (GINs), such as Ostertagia ostertagi and Cooperia spp., are common in cattle worldwide. Although infected cattle are often asymptomatic, production is negatively affected. The present study investigated whether eggs per gram (EPG) of GINs in 32 lactating cows decreased during winter and increased as it became warmer. Larvae recovered by coprocultures mostly consisted of O. ostertagi in autumn, while three GINs, Ostertagia, Trichostrongylus and Meistocirrus, were collected in spring. Daily milk and bulk tank milk samples from cows previously infected with O. ostertagi contained O. ostertagi antibodies based on ELISA developed using SVANOVIER® O. ostertagi-Ab in all survey periods. Even if the faecal diagnosis was negative for GINs, infection was still possible. Therefore, the administration of anthelmintic drugs is recommended.

日本北海道某奶牛场泌乳荷斯坦-弗里夏奶牛中Ostertagia感染的季节性动态。
胃肠道线虫(GINs),如Ostertagia ostertagi和Cooperia spp,在世界范围内的牛中很常见。虽然受感染的牛通常无症状,但生产受到负面影响。本研究研究了32头泌乳奶牛的每克产蛋数(EPG)是否在冬季下降,并随着天气变暖而增加。秋季采获的幼虫主要为ostertagi,春季采获Ostertagia、Trichostrongylus和meistocirus 3种。在所有调查期间,使用SVANOVIER®O. ostertagi- ab开发的酶联免疫吸附试验(ELISA)显示,以前感染O. ostertagi奶牛的日乳和散装罐乳样品中含有O. ostertagi抗体。即使粪便对GINs的诊断为阴性,仍有可能感染。因此,建议使用驱虫药。
