Intake and digestibility of sheep-fed alfalfa haylage supplemented with corn
The objective of this study was to determine the effect of dry corn (DC) and fermented corn (FC) supplemented to alfalfa haylage(Medicago sativa L.) (AH) on feed intake, digestibility and N balance in wether sheep. The study consisted of five feeding treatments incorporating AHalone and AH supplemented with 5 or 10 g of DC (DC5 and DC10, respectively) or FC (FC5 and FC10, respectively) kg-1 body weight d-1 to Suffolk wethers. The DC5 and FC5 treatments were higher in dry matter (DM), acid detergent fibre (ADF) and crude protein (CP) intake (P<0.001) compared with the DC10 and FC10 treatments. Both energy sources (DC and FC) and supplemental levels (5 and 10 g kg-1 body weight d-1) increased (P<0.05) the digestibility of DM and organic matter (OM), and the digestibility of OM in DM (D-value), and decreased the digestibility of ADF (P<0.05). The DC10 and FC10 treatments had higher D-values (P<0.05) and reduced ADF digestibility values (P<0.05) compared with the DC5 and FC5 treatments. The FC supplemented treatments had reduced N balances compared with the AH alone and treatments. It was concluded that DC was a better supplement to AH than FC in terms of NDF intake, CP digestibility and N balance. The main effect of increasing the level of starch supplementation to the diet was a reduced N and fiber intake, as well as N and fiber digestibility, but an increased D-value.
