| This study evaluated the influence of Tanzania-grass sward height (30, 50, 70 and 90 cm) on the morphological characteristics of the canopy, grazing behavior and forage intake by adult Anglo Nubian female goats. A completely randomized experimental design was employed, with two replicates in space and two replicates in time. Six animals were used to assess the grazing behavior, and four, the ingestion process. The rise in sward height increased the forage and leaf mass, the percentages of stem and dead material, and reduced the leaf stem-1 ratio. Above 50 cm there was an increase in grazing time and a decrease in leisure time. A positive linear correlation was detected between sward height and bite depth. The consumed forage mass, ingestion rate and daily... |

| The effects of four supplement doses (0, 1, 2 and 3 kg animal-1 day-1) on pasture characteristics and on cattle production on Brachiaria decumbens cv. Basilisk pastures in continuous stocking with variable stocking rate were assessed. Experimental design comprised completely randomized blocks with two replications. Concentrate supplementation did not influence mass (4141 kg ha-1 of DM) and production rate of forage (97.6 kg ha-1 day-1 of DM), morphological components and nutrition value in hand-plucked forage. Similarly, the number of live (1.607 tillers m-²) and dead (636 tillers m-²) tillers was not affected by concentrate supplementation. There were linear increases in animal performance (from 0.70 to 1.13 kg animal-1 day-1), stocking rate (1.9 to 3.8... |

| Pasture management with levels of leaf blades may favor significant increase in production, and the leaves indicated an important role in plant-animal relationship, caused by photosynthesis efficiency and better quality in animal diet. Current study identifies which leaf blade mass of the African star (Cynodon nlemfuensis var. Nlemfuensis) provides better productivity and nutritional value. Treatments comprised different leaf blade masses: 800, 1200, 1600 and 2000 kg of dry matter ha-1. The experimental design was completely randomized, with four treatments and three repetitions, totaling 12 plots with 100 m2 each. Results indicated increase in production, in the leaf/stem ratio and in the interval days according to increase in leaf blade mass. Daily... |

| ABSTRACT To evaluate the biomass components of massai grass subjected to nitrogen (N) fertilization levels (control - 0; 400; 800 and 1200 kg ha-1 year-1 of N) and under rotational stocking with sheep, this study was undertaken using a completely randomized design with measurements repeated in time. A quadratic response was observed reaching maximum values as the levels of nitrogen fertilization increased for green forage biomass, green leaf biomass, green stem biomass (5,172.9; 4,146.3; 1,033.9 kg ha-1 cycle-1, respectively), forage total density (179.1 kg ha-1 cm-1), canopy height (36.8 cm) and live material/dead material ratio (4.0) at levels 896; 934; 797; 879.2; 751.4 and 1,161 kg ha-1 year-1 of N, respectively. For all variables, oscillation was... |

| Thirteen genotypes of Bromus catharticus (prairie grass) were evaluated for forage production over three years using completely randomized trials with six replicates. The genotype x environment interaction was statistically significant and indicates that the behavior of genotypes differs over time. Once this interaction was detected, we used three methodologies to assess the stability of genotypes: Wricke's ecovalence, the Lin and Binns index, and the Eberhart and Russell model. The methods of Lin and Binns and Eberhart and Russell indicate that genotypes 11, 9, 3 and 4 are stable. They also rule out possible selection of genotypes 2, 10, 1 and 12 for lack of stability or poor adaptation. The correlation among these indices was statistically significant... |

| Gliricidia sepium (Jacq.) Steud. shows relatively little growth variation due to climatic differences throughout the year and between years. The purpose of this study was to evaluate various cutting strategies for the management of Gliricidia for forage production in dry and rainy periods of the year. A randomized-block factorial experimental design (12 x 2) was used for the study. The factorial setup consisted of 12 pruning management treatments (cuttings at 45, 60, 75 and 90 days with 30, 60 and 90 cm residual heights) and two periods (dry and rainy season) with four replicates. There were significant interactions between the management regime and the season for plant height, stem diameter, stem diameter and the weight of both fresh and dry forage. The... |

| ABSTRACT: The digestibility potential of leaves from forages depends on the amount of nutrition in their tissues, with low lignin deposition in the cell wall, mainly parenchyma and phloem. This research evaluated the leaf structure of different Urochloa genotypes and discussed its potential for evaluating digestibility. The cultivars U. brizantha, U. decumbens, U. ruziziensis and three clones of U. ruziziensis (1, 95 and 97), which are under development in breeding programs, were evaluated. Plants were grown under the recommended culture conditions for the Urochloa species. Plants were cut 60 days after sowing, and leaves were collected at 15 days of regrowth. Leaves were fixed in FAA 70 and further stored in 70% ethanol until being submitted to the usual... |

| ABSTRACT: Find shade-tolerant species is essential to the success of silvopastoral systems, increasingly frequent in recent years. In legumes, which have potential of biological nitrogen fixation, there is a great lack of knowledge when in shaded environments.The cultivation of four tropical forage (Neonotonia wightii, Pueraria phaseoloides, Macrotyloma axilare and Arachis pintoi) was evaluated when submitted to artificial shade levels (30, 50 and 70% shade) and in full sun during water and drought seasons. The design used was in randomized complete blocks in a sub-divided plot scheme with four replications. In the Water-season the Forage Peanuts had higher forage production in full sun (11 ton ha-1 DM), and under shade did not differ from Perennial... |

| ABSTRACT In the correct pasture management, nutritional factors such as nitrogen and potassium fertilization play an important role in the forage production and quality. The aim was to evaluate the effects of the application of water levels, nitrogen and potassium doses in the Xaraés grass in the south of the State of Tocantins. For this, Xaraés grass was cultivated in the experimental field of the Federal University of Tocantins, municipality of Gurupi, TO. We used a mixture of fertilizer, combinations of N and K2O following the 1 N: 0.8 K2O ratio. To evaluate the effect of irrigation water levels and combinations of N and K2O doses in Xaraés grass, the plant height, the crude protein content and neutral detergent fiber were determined. The greatest... |

| A produção de alimentos para os rebanhos constitui, provavelmente, o maior desafio que enfrenta a pecuária nas regiões semiáridas. Isto porque a variabilidade e incertezas climáticas tornam as culturas das forrageiras uma operação de alto risco, além de ser competitiva com a agricultura tradicional. Assim, as pastagens nativas dessas regiões tornam-se a fonte de alimentação mais importante para os animais. Nos sertões nordestino, as condições adversas do meio, fazem com que a oferta de forragem fique, muitas vezes, aquém das necessidades dos rebanhos, tanto do ponto de vista quantitativo, quanto qualitativo. Pesquisas têm mostrado que o enriquecimento da caatinga com gramíneas e leguminosas exóticas, adaptadas às condições de semiaridez, eleva a produção... |

| La producción animal representa una actividad fundamental para los pequeños empleo e ingresos, y, cuando se la compara con la actividad agrícola, es una actividad con menor vulnerabilidad a la sequía. Sin embargo, la marcada estacionalidad en la rurales, determinan que el desempeño productivo de los rebaños sea precario, en particular cuando la oferta de alimentos declina en el período seco. En este escenario, la producción y la conservación de forrajes nativos y cultivados resultan ser las únicas opciones para disponer de alimentos (Lima y Maciel, 2006).En los sertones más áridos del nordeste brasileño, por ejemplo en los del valle del río San Francisco, la crianza de pequeños rumiantes representa el sector pecuario más destacado. La cría de caprinos,... |
