| ABSTRACT - The objective of this study was to evaluate the effect of replacing wheat bran by spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on intake and nutrient digestibility and ruminal parameters of sheep. Five sheep (Santa Inês; average initial weight of 34.0±3.6 kg) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. The maximum dry matter (DM; 1414 g d−1), digestible organic matter (658 g d−1), and neutral detergent fiber corrected for ash and protein (NDFap; 425 g d−1) intakes were estimated by replacing 80.2, 89.9, and 50.5% of wheat bran. Dry matter and crude protein digestibility increased by 0.60 and 0.85 g kg-1 of DM. With the replacement of 57.1 and 62.2% of wheat bran, a maximum rate... |

| This study evaluated the replacement of Tifton hay with xiquexique (0, 12, 24 and 36%) on feeding behavior of lactating dairy cows. To this end, eight cows with average milk production of 15 kg milk day-1 and average body weight of 465.2 ± 39.4 kg were distributed in a double 4x4 Latin square. Each experimental period lasted 16 days, ten for adaptation and six for data collection. The record of behavioral variables was made every five min. for 24 hours. The times spent in feeding, ruminating and total chewing, expressed in hours day-1, as well as feeding (FE) and rumination (RE) efficiencies, expressed in g NDF h-1, the number of cuds and cud chews per day showed a linear decrease according to the levels of xiquexique in the diet. There was a linear... |
