| Resumo: A sazonalidade da produção de forragem em regiões semiáridas consiste em um dos principais entraves à produção de ruminantes a pasto. A utilização de forrageiras tolerantes ao défice hídrico consiste em estratégia viável para minimizar a oscilação na produção de forragem das pastagens. Objetivou-se avaliar a produção e a composição morfológica de pastos de dois híbridos de sorgo para pastejo submetidos a duas alturas com ovinos. Os tratamentos consistiram da combinação entre dois híbridos de sorgo para pastejo (Sorghum bicolor x S. sudanense) (híbrido BR007A x TX2785, no meado BR; e o híbrido CMSXS157A x TX2785, nomeado de CM) e duas alturas pré-pastejo (60 cm e 80 cm), perfazendo quatro tratamentos, em um delineamento inteiramente casualizado com... |

| Abstract: The objective of this work was to evaluate the effects of variable and fixed rest periods on the forage production, plant-part composition, and canopy structural characteristics of 'Tifton 85' and 'Jiggs' Bermuda grass (Cynodon spp.) pastures under rotational stocking. The treatments were two grass cultivars (Jiggs and Tifton 85) and two rest periods (grazing starting whenever the canopy reached 25 cm or every 28 days, regardless of canopy height). A completely randomized experimental design, with a 2×2 factorial arrangement (two grass cultivars and two managements), was used with three replicates. The experiment was carried out during the summer growing season in Piracicaba, SP, Brazil. Pre- and post-grazing forage mass chacteristics were... |

| This study was carried out to analyze the tillering profile of Guinea grass (Panicum maximum cv. Tanzania) pastures subjected to two grazing frequencies (time necessary to intercept 90 and 95% of the incoming light) and two post-grazing heights (30 and 50 cm) in the period from November 2005 to October 2006. The experimental design was of completely randomized blocks with three replications, in a 2 × 2 factorial arrangement. At the end of the spring, pastures managed with 90% light interception showed greater tiller appearance rates in relation to pastures managed with 95%, regardless of post-grazing height. In the summer and fall, pastures managed with post-grazing height of 30 cm showed higher tiller appearance rates in comparison with pastures managed... |
