Information related to soil moisture in integrated crop-livestock-forest systems (ICLF) are controversial. For this reason an experiment was carried out at Embrapa Beef Cattle, Campo Grande, MS, to characterize soil moisture in integrated systems with two spatial arrangements of eucalyptus trees. Experimental design was randomized block in splitplot with two replications. Plots corresponded to a 2x2 factorial, with two arrangements of eucalyptus trees (ICLF1: with 357 trees ha-1and ICLF2: with 227 trees ha-1) and two grazing heights (0.25 and 0.35 m). Split-plots correspond to sampling locations between tree rows. Soil moisture was assessed at depths of 0 to 0.2 and 0.2 to 0.4 m. There was no effect of grazing height on soil moisture. The system with higher tree density had lower soil moisture in both depths. There was no defined relation in response pattern for soil moisture in sampling sites. |

Abstract The objective of this study was to validate an electronic system for monitoring individual feeding and drinking behaviour and intake developed for young cattle housed in group. A total of 35 Holstein-Gyr crossbred heifers (BW: 180±52 kg; age: 121.5±32.5 days), fitted with an ear tag containing a unique passive transponder, were distributed in three groups of 12, 12 and 11 animals per period and had free access to 12 electronic feed bins and two electronic water bins (Intergado® Ltd). The dimensions of feed and water bins, as well as the sensors position were appropriate for young cattle. The system documented the visit frequency and duration, as well as the feed and water intakes, by recording the animal's identification tag, bin number, initial and final times of visits and the difference of feed/water weight at the start and end of each bin visit. Feed bins were monitored using time-lapse video recording over 4 days and the water bins were monitored over 6 days. For each feed bin, two feeding events were monitored using manual weighings with an external scale immediately before and after the animal's visit and the difference between them was assumed as feed intake (n=24 observations). For the water bins, 60 manual weighings were made. Video and manual weighing data were regressed on the electronic feeding and drinking behaviour and intake data to evaluate the system's precision and accuracy. The system showed high specificity (98.98% and 98.56% for the feed and water bins, respectively) and sensitivity (99.25% and 98.74%, respectively) for identifying an animal's presence or absence. Duration of feed and water bin visits as well as feed and water consumption per visit estimated by the system were highly correlated and precise compared with the observed video and manual weighing data (r 2=0.917, 0.963, 0.973 and 0.986, respectively). It was concluded that Intergado® system is a useful tool for monitoring feeding and drinking behaviour as well as water and feed intakes in young cattle housed in groups.
