• Resumen

  • The study aim was to evaluate the effect of concentrate feeder design on performance, behaviour, welfare and ruminal health in Holstein bulls fed high-concentrate diets, pretending to reduce feed wastage associated with the eating pattern and animal competence. 113 bulls were randomly distributed to 3 treatments (2 pens per treatment): conventional through feeder with 4 feeding spaces (CT), through feeder with less concentrate capacity and 4 feeding spaces (CTM), and a single space feeder with lateral protections with radiofrequency technology to register individual intake (TU). Concentrate intake was registered daily and BW every 14 days. On days 7, 119-120, 215-216 rumen fluid was collected for pH and VFA analysis and blood samples were collected for glucose, insulin and haptoglobin analysis. Animal behaviour was registered every 28 days, and lesions of rumen and liver were recorded at slaughterhouse. Concentrate consumption was reduced by 3.6% without detrimental effects on performance when animals were fed with TU, indicating that concentrate can be saved by the feeder design, but more research is needed to increase these savings. TU bulls showed some different behavioural traits, animals did not show rumen acidosis signs, and no negative impact of the feeder on performance was observed
