Ruminal (pH, N-NH3) and plasmatic (urea) parameters were evaluated in crossbred cows no lactiferous (Holstein x Zebu), canulated in rumen and inoculated with 28 g/animal/day of nitrogen no protein. The animals had been estabulated and supplied with water, mineral supplement and ground hay of Brachiaria brizantha”, ad libitum”. The treatments were: TC (control - without inoculation of nitrogen source in rumen); TU (inoculation of urea source) and TUP (inoculation of urea polymer source. The times of observations were: 0; 0.5; .1.0; 1.5; 2.0; 2.5; 3.0; 3.5; 4.0; 4.5; 5.0; 5.5; 6.0; 9.0; 12 and 24 hours after the inoculation of nitrogen source in rumen. The experimental design was Latin square 3x3 duplicate. The comparison between the averages was done the test of Scott-Knott in 5% of probability. The values of N-NH3, in treatment TUP was higher (P
