Abstract

Six sheep were used in a Latin-square experiment to investigate the effect of pre-harvest treatment of pasture with glyphosate (Roundup, a translocated herbicide) on the palatability of hay. Four hays were used: control (C), Roundup (R), quinine (Q, 100 mg/kg) and Roundup with quinine (QR). During each week one of the following choices was given to each animal: (a) C/C; (b) C/R; (c) R/R; (d) Q/C; (e) Q/R; and (f) C/QR. There were no significant effects of treatment on the proportion chosen or on total daily intake, mean meal size or rate of eating. It was concluded that neither pre-harvest treatment with Roundup nor post-harvest treatment with quinine affected the palatability of hay.
