Abstract

Seven multiparous Holsteins vs. Zebus cows with 45 + 12 days in milk and 25 kg of milk per day were used. The cows were distributed in seven treatments in a balanced incomplete block design. All the cows were in a tie stall barn receiving diets based on fresh chopped sugarcane with increasing levels of urea or OptigenII®: 0.3%, 0.6%, 0.9% and a control group without urea. There was no effect (P>0.05) for the following variables: VUR (L/day), Acu (mmol/day), CRE (mmol/day), Total Pur (mmol/day), Pabs (mmol/day), Nmic (g/day) and PMIC (g/day). It was effect (P<0.05) only on allantois concentration (mmol/day).
