| ABSTRACT: The goal of the present study was to assess the economic viability relating to the risk of replacing corn with pearl millet in diets with 80% concentration for feedlot cattle confined for 89 days. Replacement levels were: 0, 33, 66, and 100%. The risk was estimated using Monte Carlo simulation, Spearman’s rank correlation test between input variables, stochastic dominance, and analysis of sensitivity. The expected average values ± standard deviation for net present value (R$/animal) were ± 71.74 ± 283.32, 91.23 ± 285.18, 196.05 ± 273.79, and 223.80 ± 267.96 for diets containing 0, 33, 66, and 100% of pearl millet, respectively. The probability of ≥0 net present value was 63.4, 66.1, 78.4, and 82.4%, respectively. The net present values were... |

| O objetivo deste trabalho foi avaliar o perfil de ácidos graxos da carne de novilhos mestiços alimentados, em confinamento, com dietas contendo níveis crescentes de grão de milheto moído em substituição ao grão de milho moído. Foram utilizados 24 tourinhos mestiços europeus e 24 mestiços zebuínos, abatidos aos 24 meses de idade, após 96 dias de confinamento. Utilizou-se o delineamento experimental inteiramente casualizado, com os tratamentos em arranjo fatorial 4x2 (quatro dietas com 0, 33, 66 e 100% de milheto no concetrado e dois grupos genéticos) com seis repetições. O aumento dos níveis de grão de milheto na dieta elevou linearmente a participação dos ácidos graxos, araquídico (C20:0), heneicosanoico (C21:0), α-linolênico (C18:3 n-3) e... |

| ABSTRACT The objective of this study was to assess the effects of including crude glycerin in the diet on intake, performance, rumen development, and carcass traits of dairy crossbred veal calves fed starter concentrate containing 0, 80, 160, and 240 g kg−1 crude glycerin. Twenty-eight calves with an average weight of 38.03±6.7 kg and five days of age were distributed in a completely randomized design with four treatments with seven replications. Calves were individually housed in covered stalls equipped with feeders and drinkers for 56 days. The calf response to inclusion of crude glycerin in the concentrate changed over the weeks and the inclusion level of 240 g kg−1 resulted in greater dry matter intake and average daily gain. There was no effect on the... |
