Abstract
The effect of Tritrichomonas foetus var. brisbane infection on calf production by Hereford cows was determined. The mean number of calves produced by cows that were kept continuously with bulls infected with T. foetus for 3 years was 17.6% less than the mean number produced by cows kept with a non-infected bull. Losses in production due to trichomoniasis occurred each year, but were greatest in the first 2 years in cows experiencing infection for the first time.
摘要
研究了布里斯班胎儿三毛滴虫感染对赫里福德奶牛产犊的影响。连续3年与感染胎儿三毛滴虫的公牛饲养在一起的母牛所产犊牛的平均数量，比与未感染公牛饲养在一起的母牛所产犊牛的平均数量少17.6%。滴虫病导致的生产损失每年都有发生，但在首次感染的母牛中，前两年的损失最大。
