The objective of the present study was to evaluate the effect of the use of babassu mesocarp meal (BMM) and corn in different physical forms on the feeding behavior of crossbred young bulls of a dairy breed. Twenty-four crossbred (Nellore vs. Holstein) steers (307.35 kg) were fed four experimental diets containing two levels of inclusion of the babassu mesocarp meal (0 and 412.4 g/kg) and corn in two physical forms (kernels or ground) for 98 days. Data was collected on […]

Ingestive behaviour of beef heifers and sward structural characteristics of Pearl Millet (Pennisetum americanum (L.) Leeke) were evaluated. The experiment was carried out in a randomized complete design following a repeated measure arrangement (three experimental periods) with three replications of two leaf blade masses (600 and 1,000 kg/ha DM), which were maintained using continuous grazing with variable stocking rate. The variables measured were sward height, herbage mass, leaf blade and stem bulk density in sward vertical strata (sward structural characteristics), […]

The experiment was performed in a natural pasture to evaluate the effect of the forage offer level on the pasture structure and ingestive behavior of steers. A completely randomized block design with four daily green forage offer levels (4, 8 12 and 16 kg GFDM/100 kg LW) and two replicates was used. The continuous grazing method with variable stocking rate was used. The increasing forage offer enhanced the higher strata frequency and determined higher inferior strata height. The increasing inferior […]

The objective of this trial was to evaluate the chewing activity of dairy heifers fed diets in which Tifton 85 hay (Cynodon dactylon (L.) Pear) was partially replaced by citrus pulp. Twenty-eight Holstein dairy heifers averaging 12 months of age and 184 kg of BW at the beginning of the trial were blocked by initial BW and, within each block (7 blocks), randomly assigned to one of the following four treatments: 0, 16.6, 33.3, or 50% of a concentrate based […]
