13. Piata palisade grass deferred with two distinct initial heights: luminous environment and tillering dynamics
The study was carried out between March 1st and July 1st, 2011, in order to evaluate the tillering pattern of the deferred Piata palisade grass (Brachiaria brizantha cv. Piata). Three sward heights were evaluated in the beginning of the period of deferment: lower (20 cm), medium (30 cm) and higher (40 cm). The experimental design was of completely randomized

14. ESTUDO DA RECRIA DE NOVILHAS DE CORTE EM PASTAGENS CULTIVADAS DE VERÃO / STUDY OF BEEF HEIFERS REARING ON WARM-SEASON PASTURES
Heifers rearing is a determinant step of efficiency in beef cattle production systems on pastures. Several experiments have tested alternative uses for tropical grasses to heifers rearing. In order to summarize results and making not visible relationships evident in these individual experiments an analysis was performed in a set of data from six experiments

15. USO DE GRÃO DE MILHO INTEIRO OU LAMINADO COMO SUPLEMENTO PARA BEZERRAS DE CORTE EM PASTEJO EM AZEVÉM / USE CORN GRAIN WHOLE OR STEAM ROLLED AS A SUPPLEMENT FOR BEEF HEIFERS GRAZING ON RYEGRASS PASTURE
The performance of beef heifers grazing Italian ryegrass (Lolium multiflorum Lam) from eight until twelve months receiving or not energetic supplement (whole corn grain or steam-rolled) at level of 1% body weight were studied. The grazing method was continuous with variable number of animals. The suplement was given daily at 2 pm and presented 9,5% crude pro

16. Dynamics of production and forage utilization on elephant grass pastures managed with different post-grazing heights
This study was conducted to evaluate the daily production of forage and its morphological components, as well as the potential of forage utilization in pastures of Pennisetum purpureum cv. Napier managed with three post-grazing heights (30, 50 and 70 cm). Two experiments were carried out: one from February to May 2009 and another from December 2009 to May 20

17. Frequencies and intensities of defoliation in Aruana guineagrass swards: morphogenetic and structural characteristics
The objective of this study was to evaluate the morphogenetic and structural characteristics of Aruana guineagrass pastures (Panicum maximum cv. Aruana) subjected to rotational stocking by sheep. The treatments corresponded to grazing when swards reached 95 or 98% of interception of incident light (LI) until post-grazing heights of 10 and 15cm and were alloc

18. Forage mass and structure of piatã grass deferred at different heights and variable periods
The objective of this study was to determine the deferment period and the most adequate initial sward height of Brachiaria brizantha cv. Piatã for deferment in the region of Viçosa, Minas Gerais. For so, the following characteristics were evaluated: masses and bulk density of forage and its morphological components, light interception by the sward, leaf ar

19. Characterization of tillers in deferred Piata palisade grass with different initial heights and nitrogen levels
This experiment was conducted to estimate the effects of nitrogen fertilization associated with the initial height of the Piata palisade grass on the number and structural characteristics of individual tillers after the deferment period. An area with Brachiaria brizantha cv. Piata measuring approximately 288 m² was used. Combinations of levels of nitrogen f

20. Piata palisadegrass deferred in the fall: effects of initial height and nitrogen in the sward structure
The objective of this study was to evaluate the mass of the forage and of the morphological components, and the sward structure in Piata palisadegrass (Brachiaria brizantha cv. Piata) deferred in function of different initial heights and nitrogen levels. Two levels of nitrogen (75 and 150 kg/ha) and one control without fertilization associated to three initi

21. Biomass accumulation in mombasa guineagrass plants under different levels of nitrogen supply and plant densities
The objective of this study was to evaluate the effect of different levels of nitrogen supply and plants densities in the productivity of mombasa guineagrass (Panicum maximum) in the period of establishment. The design was of completely randomized blocks, with 12 treatments and three repetitions, with four nitrogen supplies (absence of application, 80, 160 a

22. Morphogenesis in guinea grass pastures under rotational grazing strategies
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter) when sward light interception reached 95% during regrowth. Post-grazing heights were allocated to experimen

23. Productivity, utilization efficiency and sward targets for mixed pastures of marandugrass, forage peanut and tropical kudzu
This study was carried out to evaluate the productivity and utilization efficiency of a mixed marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides) pasture, rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight), in order to define
