| This study evaluated the possibility of decreasing defecation in a bedding area by inducing a heifer to visit a feeding station within a few minutes or immediately after standing. An experimental paddock (11.3 x 6 .8m) was made outdoors. Half of the paddock was roofed and bedded with straw to form a resting area. A feeding station was situated in the remaining area of the paddock，which was designated as the feeding area. Six Holstein heifers，the test subjects，were grouped together in the paddock. A standing detection device was developed and attached to the heifer's left hind leg. The feeding station had an antenna that identified the heifer carrying the ID-tag when it entered the station. This experiment included control period and an experimental... |

| The experiment was carried out to evaluate forage intake, performance and ingestive behavior of beef heifers. Productive, structural and chemical characteristics of the pasture were also evaluated. The experimental design was completely randomized in a 3 × 2 factorial arrangement, with three pasture systems (Alexandergrass [Urochloa plantaginea Link.] with and without supplement to heifers and Coastcross [Cynodon dactylon (L.) Pers.]) and two phenological stages: vegetative and flowering. The grazing method was put-and-take stocking. Grazing, ruminating and idle activities, feeding stations, displacement patterns, bite mass and bite rate were evaluated. The forage intake was estimated using chromic oxide as an indicator of fecal output. The heifers... |

| Analyses in a data set of six experiments (n=436) was performed with the aim of characterizing canopy structure and forage intake patterns of beef heifers grazing on Pearl millet (Pennisetum americanum), Alexandergrass (Urochloa plantaginea) and Coastcross (Cynodon dactylon). Forage and leaf lamina mass were similar among species, 3001.4 and 668.1kg of DM/ha, respectively, while leaf:stem ratio of canopy vertical strata was different. Intake rate (12g DM/minute), bite mass (0.343g DM/bite) and bite rate (36.6bites per minute) were similar in Pearl millet and Alexandergrass. In Pearl millet, neutral detergent fiber content (56.1%) in forage as grazed, grazing time (518.9 minutes/day) and displacement rate (8.8 steps/minute) were lower. Increased grazing... |
