研究了6头奶牛在泌乳早期9周内，每周感染1.5万只毛线虫幼虫的产奶量与6头未感染的产奶量进行了比较。经协方差分析调整感染前产奶量差异后，感染奶牛产奶量比未感染奶牛少2.16 kg/d。
The milk production of 6 cows infected with 15,000 infective trichostrongylid larvae per wk for 9 wk in early lactation was compared with the milk production of 6 uninfected cows. After adjustment for differences in pre-infection milk production by covariance analysis, the infected cows produced 2.16 kg/day less milk than the uninfected cows.
