Abstract
From about 200 to 320 kg liveweight 4 groups of 5 Romanian Brown bullocks 6 to 8 months old were given mixed feeds of dried lucerne 30, 25, 30, 12, maize cobs 25.5, 18.5, 29.5, 46.5, grape marc meal 6, 20, 0, 0, maize meal 25, 25, 23, 20, wheat bran 8, 0, 8, 0, and molasses 5, 8, 7, 8% with urea 1% and minerals and vitamins; controls were given a diet based on green fodder. Mean daily gain for those on the mixed feeds was 1270, 1210, 1330 and 1200 g and for controls was 650 g. The mixed feeds, particularly that with 20% grape marc meal, were more economical than the green fodder and concentrate. In the second experiment bullocks weighing initially 187.5 kg were given for 153 or 184 days mixed feeds based on 45% maize cobs or 30 or 46% maize stover with fibre removed; controls were given green fodder and a concentrate. Mean daily gain was 1055 g for those given maize cobs, 895 g for controls and 715 and 704 g for those given stover. Intake of principal nutrients per kg gained was 10% less in all experimental groups than in controls.
