Abstract

A field trial involving 217 dairy cows from 13 herds located in four different areas of Quebec was conducted to determine the level of subclinical parasitism. The effect on milk production was evaluated on 116 cows following a single anthelmintic treatment with morantel tartrate administered at freshening. The results showed that this treatment increased milk production in nine herds, which was statistically significant at P </= 0.05 in one of the herds and decreased yields in four herds. Overall, this treatment increased milk production by an average of 255 kg per cow for the official 305 day production period. This increase was found to be not statistically significant (P>0.05).

摘要

为确定亚临床寄生虫感染水平,在魁北克四个不同地区的13个牛群中对217头奶牛进行了田间试验。在产犊时用酒石酸噻嘧啶进行单次驱虫治疗后,对116头奶牛的产奶量影响进行了评估。结果表明,这种治疗使9个牛群的产奶量增加,其中1个牛群在P≤0.05时具有统计学意义,4个牛群的产奶量下降。总体而言,在官方规定的305天产奶期内,这种治疗使每头奶牛的产奶量平均增加了255公斤。发现这种增加没有统计学意义(P>0.05)。
