Abstract

Toxic Festuca: its effect on different cattle breeds.

Abstract

Festuca arundinacea pastures in Argentina are sometimes infected by the fungus Neotyphodium coenophialum. The effect of feeding on infected tall fescue on weight gain of 140 Aberdeen-Angus and Hereford steers and 40 Indian crossbred steers (Bradford × Brahman) was investigated. Animals grazed for 166 days (winter-spring). Weight gain of animals grazing on infected pastures was 37% lower than that of animals grazing non-infected tall fescue. The difference in meat production/ha of British breeds on infected and uninfected pasture was 212 kg, compared to 152 kg for Indian crossbreds.
