Extract

Concentrate feed with high-glucosinolate rapeseed meal (BRSM) as the sole protein supplement was eaten less readily by weaned calves than a similar feed based on soyabean meal (Stedman et al, 1983), and this was so whether intake was measured during continuous ad libitum feeding, or for short periods, 0.5 h, after twice-daily feeding with changes of feed each day. In these and other experiments with calves (Stedman and Hill, 1987), concentrate feeds based on low-glucosinolate rapeseed meal were eaten more readily than those based on high-glucosinolate meal, but intake of the low-glucosinolate feeds rarely matched that of the corresponding feed containing soyabean meal.
