Intake, animal performance and methane (CH4) output was investigated using 36 finishing Charolais cross heifers (mean starting weight 462 kg, S.D.±16) fed ad libitum over an 11-week period. Six dietary treatments were investigated in a randomised block design experiment with a factorial arrangement of treatments. The six experimental diets consisted of three forage/concentrate (F/C) ratios (0.65:0.35, 0.40:0.60 and 0.10:0.90) supplemented with two levels of coconut oil (0 or 350 g/day). Rumen protozoa numbers were significantly (P 0.05) interaction between the F/C ratio and coconut oil level was identified although coconut oil significantly reduced dry matter intake (DMI), CH4 l/day and LWG on the 0.65:0.35 F/C ratio diet. |
