ABSTRACT

Six lactating Suffolk ewes and eight lactating Rambouillet ewes, with twins, were used to determine breed differences in the voluntary intake of a Lolium multiflorum pasture, under continuous grazing. Fecal production was estimated using 1 g of chromium sesquioxide per sheep as an external marker, administered in two gelatin capsules per animal, before and after the grazing period (7:00 and 17:30 h), from the fourth to the 64th day after parturition. Fecal samples were collected directly from the rectum of each animal during three consecutive days, on days 18-20, 33-35, 48-50 and 63-65 postpartum. The in vitro dry matter (DM) digestibility of the forage was estimated for the same days taking three daily hand-plucked samples of forage. With this information, voluntary intake per animal and per metabolic bodyweight was estimated. Data were analyzed using a completely randomized design with repeated measures. Voluntary intake expressed in kg of DM per animal (Suffolk = 3.28 vs. Rambouillet = 2.44) and per metabolic bodyweight (Suffolk = 0.1045 vs. Rambouillet = 0.1422 kgBW0.75) was lower for the Suffolk than for the Rambouillet ewes, which was probably due to a better performance of the Rambouillet breed under grazing conditions.
