摘要: The objective of this study was to estimate herbage intake in Danish Friesian and Jersey steers at an age 8-9 months on ryegrass / white clover pasture. were turned out pasture late April estimated June a mean live weight (± S.D.) 264 ± 14 kg 185 25 for respectively. Faeces samples analysed alkanes dry matter intake, digestibility (DMD) botanical composition intake. gains the time estimation (kg/day) 1.142 265 kg/day 0.927 168 Daily (kg (DM)) by C32 /C33 8.33 0.97 6.28 0.61 per day (P<0.001) 3.15 0.32 3.43 0.30 100 liveweight (LW) (P<0.05) diet same with about half being grass leaves other leaves. It is concluded that have higher LW than age, but metabolic not different between two breeds.
