Animals were randomly selected on different dietary treatment at different cycle. For each cycle, animals were provided with concentrate on the morning and ad libitum feeding of Napier grass thereafter. Clean drinking water were made available all the times in the respective animal watering troughs. The goats were supplemented with two types of dietary fats (VCO and lard) at 3 and 5%.
