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 1g 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 V5. Rambouillet = 2.44) and per metabolic bodyweight (Suffolk = 0.1045 V5. 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. |

Clarifying cultivation techniques and making production systems more efficient are practices that have been much sought after in agricultural systems in recent decades. In this context, the forage yield, biological efficiency, and competitive ability, of different cultivation strategies for intercropping forage cactus and sorghum were determined in biosaline production systems from 2018 to 2020 in Brazil. Four experiments were carried out, comprising: 1) cropping configurations for the forage cactus-sorghum intercropping system; 2 and 3) planting densities for the forage cactus intercropped with sorghum with an east-west and north-south row orientation, respectively; and 4) planting densities for the forage cactus and sorghum. Each experiment used a randomised block design with four replications. The intercropped forage cactus and sorghum showed higher productivity than the monocropped systems. The indices of biological efficiency (LER, ATER, LEC and SPI with mean values equal to 1.6, 1.8, 0.6 and 29.0, respectively) and competitive ability (ALGY in average 870.6) show better performance under the intercropped system compared to the single crops. The increased planting density resulted in an increase in productivity under the intercropped forage cactus-sorghum system (on average an increase of 69.4% dry matter). In turn, the orientation had no influence on the productivity of the intercropping system but offered better conditions for the forage cactus when cultivation was in an east-west direction (21.7 Mg ha 1 of dry matter) compared to north-south (17.5 Mg ha 1 of dry matter). Intercropping forage cactus and sorghum using biosaline agriculture is an excellent alternative for a production system in semi-arid environments, especially at higher planting densities (50,000 and 100,000 plants ha 1).
