The objective of this study was to evaluate tiller demography, pasture morphological composition, leaf area index, dry matter herbage accumulation, dry matter in vitro digestibility and crude protein, neutral detergent fiber (NDF) and lignin contents of Brachiaria decumbens cv. Basilisk (Signalgrass), under nitrogen fertilization (75, 150, 225, 300 kg/ha.year of N) and continuous stock management with variable stocking rates, for two consecutive years. A randomized complete block design was used with two replications. In the first year, tiller demography did […]

It was evaluated tiller appearance, mortality and survival rates, the flowering percentage and the population density of basal tillers in pasture of Brachiaria decumbens under four doses of nitrogen (75, 150, 225 and 300 kg/ha/year), in three periods of the year: February to April, May to August and September to November. The experiment was conducted in a completely randomized design with periods as a split plot feature, with two replications. The nitrogen fertilization was split in three applications the first […]

The objective of this trial was simulate and validate the ruminal degradation of carbohydrates and the flow of microbial nitrogen, estimated from samples of esophageal extrusa and supplements, using an in vitro gas production technique. In vivo estimates were obtained from five Holstein x Zebu steers averaging 304 kg of body weight and 24 months of age that were grazing on five paddocks of Brachiaria decumbens (0.34 ha). The supplements fed to the steers (4 kg/animal/day) contained: grounded corn, whole […]

The objective of this trial was to evaluate ruminal, intestinal, and total tract apparent digestibilities of nutrients as well as metabolism of ruminal and nitrogenous compounds in supplemented finishing cattle during the drought to rainy transition season. Five Holstein x Zebu steers averaging 304 kg of live weight and 24 months of age located in five paddocks (0.34 ha each) of Brachiaria decumbens were used in this trial. The supplements fed (4 kg/animal/day) contained ground corn, whole soybean, urea, ammonium […]

The objective of this trial was to evaluate the voluntary intake and ruminal passage of particles in supplemented finishing cattle during the drought to rainy transition season. Five Holstein x Zebu steers averaging 304 kg of live weight and 24 months of age located in five paddocks (0.34 ha each) of Brachiaria decumbens were used in this trial. The supplements fed (4 kg/animal/day) contained ground corn, whole soybean, urea, ammonium sulfate, and minerals and were formulated to yield, on as-fed […]
