EFFECT OF CALCITIC CALCARIUM ON RUMINAL pHEFEITO DO CALCÁRIO CALCÍTICO NO pH RUMINALCalcitic calcariumruminal pHCalcário calcíticoph ruminal The experiment was carried out at the Zootechny Department of Goiás Federal University, Brazil. Twelve sheep were divided in blocks and confined in individual metabolic cages. Three isoprotein and isoenergetic concentrates with 0, 2 and 4% CaCO3 were evaluated for ruminal fluid pH and blood levels of glucose and urea. One hour after a concentrate intake, ruminal fluid showed pHs of 5.66, 7.11 and 7.02, which were significantly different (P=0.05) eight hours (5.93, 7.20 and 7.11 for 0, 2 and 4% CaCO3, respectively). Blood glucose averaged 86.20, 71.4, 58.87 and 77.22 mg/l after 1 hour and 75.4, 58.87 and 77.22 mg/ml after 8 hours, differing significantly at P=0.05. Blood urea values showed no significant difference between one and eight hour periods after intake. Values were 34.25, 37.77 and 31.55 mg/ml after one hour and 29.52, 34.42 and 27.85 mg/ml after eight hours. Results showed that CaCO3 changes ruminal pH and products of fermentation and blood metabolites. KEY-WORDS: Calcitic calcarium; ruminal pH. O experimento foi conduzido no Departamento de Zootecnia da Escola de Veterinária da Universidade Federal de Goiás. Foram utilizados 12 ovinos, divididos em blocos e confinados em gaiolas individuais de metabolismo. Os tratamentos consistiam de três concentrados isoprotéicos e isoenergéticos contendo níveis de 0; 2 e 4% de calcário (CaCO3). Foram analisados o pH do líquido ruminal, glicose e uréia séricas. Os valores médios do pH do líquido ruminal para uma hora após o consumo de concentrado foram de 5,66; 7,11 e 7,02, e para oito horas, 5,93; 7,20 e 7,11, para os níveis de 0; 2 e 4% de CaCO3, sendo esta diferença significativa ao nível de 5%. Os valores médios de glicose sanguínea, para uma hora, foram de 86,20; 71,05 e 85,17 mg/l, e para oito horas após o consumo dos concentrados, de 75,40; 58,87 e 77,22 mg/ml, com diferença significativa (P=0,05). Os valores de uréia sérica não apresentaram diferenças significativas e foram de 34,25; 37,77 e 31,55 mg/ml, para uma hora, e de 29,52; 34,42 e 27,85 mg/l00 ml para 8 horas. Conclui-se pelos dados observados que o CaCO3 altera o pH ruminal e, por conseqüência, os produtos da fermentação (AGV’s) e os metabólitos sangüíneos.
