Abstract

Eight Holstein calves had their rumens's volumes estimated through polyetilenglicol (PEG) utilization; animals were next, slaughtered to evaluate the estimations. A technique was developed to colect rumen contents by aesophagel canula. Data showed this technique must be improved, because the correlation between estimated rumen volumes and weight of rumen contents was low (r = 0,292). Correlations between: feed consumption x weight of rumen's contents; feed consumption x  calve's weight; calve's weight x rumen contents, were significant.
