Método simple para recolección total de orina de vacas en pastoreo de gramíneas o arbustivas

Abstract

The design and evaluation of a methodology for total urine collection in browsing and/or grazing cows is presented. The bag was test using 4 cows (Bos taurus x B. indicus) of 415 kg LW. Grazing/browsing time was 20 hours/day. The device worked well and without urine loss or contamination with faeces. Urine collection was on average: 12.8, 13.6, 11.97 and 12.3 kg/d and no significative differences were found.
