Failure of oral zinc therapy to alleviate Bacteroides nodosus infections in cattle and sheep. 1985

J R Egerton, and E A Laing, and R C Mulley

Cattle and sheep with Bacteroides nodosus infection were treated orally with both high (65 mg Zn/kg and 82 mg Zn/kg) and low (1 mg Zn/kg and 8.6 mg Zn/kg) doses of zinc sulphate respectively. The lower dose rates administered weekly for one month, in the case of cattle, or daily for 2 weeks, in the case of sheep, had no effect either on serum zinc levels or the prevalence or severity of infection in treated animals. High dose rates of zinc (approximately 2.5 g Zn per head per day) were required to elevate serum levels above those normally present in both cattle and sheep. Even these dose rates continued daily for about 2 weeks had no beneficial effect on B. nodosus infection in either species.
