Abstract

A trial was undertaken to determine whether a bloat drench containingcopper (Cu), cobalt (Co), selenium (Se), and iodine (I) would by-passthe reticulo-rumen (rumen) of cows. Six rumen-fistulated cows were fed pasture at a range of intakes so that there was an 8-fold range in rumen dry matter (DM) pool size, and the Cu in the drench was used as amarker. The extent to which the rumen Cu pool size increased as a consequence of drenching was used to indicate the fate of the drench. Theincrease in the rumen Cu pool with drenching showed 30-100% of the drench (mean 71.3 +/- SE 5.15%) remained in the rumen 25-30 min after administration and recovery was not affected by rumen fill or saiety. Itis suggested that the low and variable recoveries could be the resultof a slow dispersion of drench in the digesta, so that drench which was concentrated in the cranial reticulo-rumen passed rapidly to the abomasum. The drench did not appear to elicite a closure of the oesophageal groove.
