The aim of this study was to evaluate the intake, digestibility, water balance and growth performance of lambs receiving diets containing cactus silage under an intermittent water supply. Thirty-six male, uncastrated Santa Inês lambs with an initial weight of 19.8 ± 2.1 kg and age of 6 months were distributed in a 3 × 3 factorial arrangement, with three proportions of cactus pear in the diets (0 (control diet containing Tifton hay), 21% and 42% of dry matter) and three periods of intermittent water supply (0, 24 and 48 h), with four repetitions. Lambs that received diets non-isonitrogenous with cactus silage showed higher intakes of dry matter (p < 0.001), total digestible nutrients (p < 0.001), water excretion via faeces (p < 0.001) and water balance (p < 0.001). Lambs that received diets with cactus silage showed higher digestibility of total carbohydrates, non-fibre carbohydrates (p = 0.005), water intake via food (p < 0.001), total water intake (p < 0.001), water excretion via urine (p < 0.001) and water balance (p < 0.05), when compared to the control diet. Lambs that received diets with cactus silage promoted growth performance (p = 0.001). When using 42% forage cactus silage in place of Tifton hay and water offered at 48 h intervals, intake, digestibility, and performance of feedlot lambs were improved. |

Rice is a staple food for more than 50% of the world's population. Based on land and water management practices, rice ecosystem is mainly divided into lowland, upland, and deep water or floating rice. However, major area and production at global level comes from lowland or flooded rice system. In rice growing regions nitrogen (N) is one of the most yield-limiting nutrients for rice production. Adaptation of cultivars or genotypes with high N use efficiency is a potential strategy in optimizing N requirements of crops, lowering the cost of production and reducing the environmental pollution. The objectives of this paper are to discuss rate and timing of N application, define N?use efficiency, discuss mechanisms involved for genotypic variation in N?use efficiency and present experimental evidence of genotypic variations in N-use efficiency in lowland rice. Evaluation methodology and criteria for screening N-use efficiency are also discussed. Significant variation in N use efficiency exists in lowland rice genotypes. Nitrogen use efficiency parameters (grain yield per unit of N uptake, grain yield per unit of N applied and recovery of applied N) are useful in differentiating lowland rice genotypes into efficient and non?efficient responders to applied N. Such an evaluation could assist in identification of elite genotypes that could be used in breeding program to produce cultivars with high N use efficiency and capable of producing high yields. |
