he use of forage legumes to contribute biologically fixed nitrogen (N) to pastures is an alternative to increase beef cattle production in tropical regions. The objective was to compare the impact of the introduction of a legume with that of N fertilizer application on forage and animal production in Brachiaria pastures. This two-year study assessed three pasture treatments: (1) mixed Marandu palisadegrass (Brachiaria brizantha [syn. Urochloa brizantha] cv. Marandu) and the legume ?ovalifolium? (Desmodium ovalifolium) cv. Itabela (Mixed), (2) Marandu palisadegrass pastures with 150 kg N ha−1 (Fertilized), and (3) Marandu palisadegrass without N fertilizer (Unfertilized). Rotational stocking with a variable stocking rate was used with a target herbage allowance of 1.0 kg forage kg body weight−1. The pre-grazing green herbage mass was similar for Fertilized and Mixed pastures, with 54% and 63% more mass than Unfertilized pasture, respectively (p < .001). Cattle that grazed the fertilized pasture had the greatest average daily gain (ADG; p = .017). The stocking rate and liveweight gain per area were greatest for the Fertilized and Mixed pastures (p < .001 and p < .001, respectively). No differences between treatments were found for DM forage intake (p = .555). Organic matter digestibility was lowest (p < .001) for the Mixed pasture. The inclusion of the ovalifolium legume in the Marandu pasture had the same impact on beef cattle production as annual fertilization with 150 kg N ha−1. The potential and environmental benefits of ovalifolium are discussed.

The aim of this study was to evaluate the effect of reducing water supply for watering of Santa In?es ewes on carcass characteristics, non-carcass components and the volume of digestive compartments. Thirty-two crossbred Santa In?es ewes, with an average body weight of 32.2 ± 7.4 kg, were distributed in a randomized block design with four treatments (different supply levels - 100% (ad libitum), 80%, 60% and 40% ad libitum water intake treatment) and eight repetitions. The animals were confined for 63 days until slaughter. The decrease in water availability promoted a linear decreasing effect for the internal carcass length (P = 0.032). A quadratic effect was found for the volume of the omasum (P = 0.018) and abomasum (P = 0.039), with maximum volumes of 0.305 and 1.636 liters, respectively, for 40% supply. The reticulum yield showed a quadratic effect (P = 0.044) with a maximum point in the supply of 100%, with 0.527%. The reduction in water supply promoted a quadratic effect for the weight (P = 0.016) and yield (P = 0.030) of the bladder, with maximum yields found in the supply of 60%, with 0.067 kg and 0.233%, respectively. There was a quadratic effect for weight (P = 0.042) and yield (P = 0.029) of the diaphragm with higher values found in the supply of 60%m with 0.272 kg and 0.927%, respectively. There was a quadratic effect for kidney yield (P = 0.022) with higher yield for 100% supply. Therefore, the reduction in water supply levels by up to 40% in relation to voluntary intake can be a strategy to be used in cases of water scarcity, as it does not cause negative effects on the Santa In?es ewe carcass.
