Abstract
The objective of this study was to determine the effect of fermented corn grain (FC) supplementation to alfalfa haylage (AH) on ad libitum water intake and water balance by wether sheep. The study consisted of 3 feeding treatments: (i) feeding AH only (AH); (ii) feeding AH with the supplementation of 5 g FC kg-1 body weight of wether sheep (AH5) and (iii) feeding AH with the supplementation of 10 g FC kg-1 body weight of wether sheep (SL10). The experiment was set up as a 3x3 Latin square. The animals were fed twice a day, all the time they had at libitum acces to fresh water. In the AH5 and AH10 treatments, lower water intake by drinking (P<0.05) and lower intake from food (P<0.05) were found in comparison with the AH treatment. The supplementation of AH with FC decreased urinary water excretion (P <0.05) and increased faecal water excretion (P<0.05) compared to AH treatment only. AH5 treatment excreted more urine (P<0.05) compared to AH10 treatment. The FC supplementation to AH reduced the water balance of wethers (P<0.05) compared to the water balance of wether sheep fed AH only. It was concluded that the addition of FC to a AH based diet affects water intake and excretion in wether sheep.
