ABSTRACT This trial was designed to evaluate the effect of processing method of rehydrated corn grain silage (RCGS) on feed intake, performance, carcass traits, feeding behavior, rumen morphology, and blood metabolites of cattle in the finishing phase. Thirty-eight F1 Angus × Nellore bulls (365±22 kg) raised under grazing conditions were housed in individual pens (2 × 4 m) for the feeding trial. At the end of the adaptation period, animals were weighed after a 16-h fast, blocked by shrunk body […]

The objective was to evaluate the processing of the grain of millet in supplements given daily or three times a week to grazing beef cattle on productive performance, economic and diurnal intake behavior during the drought period. Twenty-five non-castrated Nelore cattle with initial body weight of 350.92±31.7 kg were kept in five paddocks with unit area of 1.45 ha formed by B. brizantha cv. Marandu. The animals were distributed in a completely radomized design in a 2 × 2 + […]

The aim of this work was to evaluate, the replacement of ground or extruded corn by sorghum ground or extruded in the concentrate used in diets for equines. Four mares with an average weight of 450 kg and 24 months of age, non-defined breed were distributed to a 4 × 4 Latin square experimental design in a 2 × 2 factorial arrangement (ingredient – corn and sorghum × processing form – ground and extruded). Apparent digestibility of total diet and […]

The objective of this trial was to evaluate the effect of starch sources and processing used in diets on performance and nitrogen metabolism of lactating Holstein dairy cows fed sugar cane as forage. Five multiparous lactating Holstein cows, cannulated in the rumen and proximal duodenum, were used in a 5 × 5 Latin square. Cows were fed a 40:60 forage concentrate ration (40% fresh sugar cane and 60% concentrate) and differ only on processing or mainly starch source: cracked corn; […]

The objective of this trial was to investigate the effects of feeding corn with different particle size (coarse vs. fine grinding) plus dried citrus pulp or soyhulls on performance of lactating dairy cows. Thirty-two mid lactating Holstein cows averaging 160 days in milk were randomly assigned to eight replicated 4 x 4 Latin squares with a 2 x 2 factorial arrangement of treatments. Animals were fed total mixed rations containing corn silage as the sole forage source. Each experimental period […]

Growth performance was evaluated in 72 Holstein calves fed milk replacer or whole milk diet and a starter containing steam-flaked corn at: 283, 360 or 437 g/L. The animals were blocked by birth and sex in a 2 x 3 factorial design. Enzymatic in vitro starch availability of the steam-flaked corn decreased as grain densities increased. During the post-weaning period, there was no effect of the processed corn at the different densities and type of the liquid diet on dry […]
