| Este experimento foi conduzido com o objetivo de avaliar algumas características da silagem de capim-marandu (Brachiaria brizantha Stapf cv. Marandu) submetida a diferentes tempos de emurchecimento. O delineamento experimental usado foi o inteiramente casualizado com quatro tratamentos e quatro repetições. Os tratamentos foram tempos de emurchecimento de zero, duas, quatro e seis horas após o corte, em pleno sol. A gramínea foi colhida com aproximadamente 90 dias de rebrota e permaneceu ensilada por 40 dias em silos experimentais de canos de PVC. Determinaram-se os valores de pH, poder tampão (PT) e os teores de MS, PB, FDN, FDA e nitrogênio amoniacal (N-NH3). Pelas características analisadas, pôde-se concluir que o capim-marandu ensilado após... |

| ABSTRACT The study evaluated the average return on invested capital (ROIC) in function of the variations in the historical prices of beef cattle and the odds of return on that capital gain within the system of beef cattle fattening on a farm in the state of Minas Gerais, Brazil, from 2004 to 2007. To calculate the risk of ROIC, monthly data of beef cattle prices (BM&F) were used from July 1997 to December 2013, revised by the General Price Index of the Fundação Getúlio Vargas in December 2013. The corrected data were divided into five classes that correspond to the risk scenarios. In light of these classes, the observed frequencies and their respective probabilities were calculated. The cumulative and updated ROIC were -3.02 and 0.24%, respectively.... |

| ABSTRACT The objective of this study was to evaluate residual feed intake (RFI), residual intake and body weight gain (RIG) and their relationship with other traits of efficiency, performance, and economic analysis of sheep. Lambs (n = 102) were evaluated during 56 days and a herd consisting of 500 ewes was simulated with the mean of dry matter intake (DMI) and final body weight of the lambs, the same as that of the experimental lambs. The lambs were fed hay-based diet of Tifton 85 (Cynodon spp.), corn, and soybean in the voluminous:concentrate ratio of 35:65. Residual feed intake and RIG were correlated with DMI, feed conversion ratio, and feed efficiency. Residual intake and body weight gain were positively correlated with average daily gain, relative... |
