摘要：

Individual water consumption and intake per unit body mass gain of 16 castrated Boer goat (BG) kids and 16 South African Mutton merino (MM) wether lambs were investigated. Two pelleted diets (fed to eight animals per species) with either a low (8.9 MJ ME kg(-1) DM) or a high (10.9 MJ ME kg(-1) DM) metabolisable energy level were fed individually, ad libitum for 56 days. The BG had a 49% lower (P < 0.01) water intake per kilogram mass gain than the MM on both the high and low energy diets. Both species had a lower (P < 0.01) intake on the high than on the low energy diet. Furthermore, the BG had a daily water intake of only 171 ml kg(-0.75) compared to the 302 ml kg(-0.75) of the MM.
