Se obtuvieron muestras de suero de 23 añujes criados bajo condiciones similares. Los animales fueron capturados y anestesiados mediante ketamina y Xilacina. Se determinó mediante métodos colorimétricos los niveles de urea y creatinina sérica utilizando kits comerciales. Los valores obtenidos fueron los siguientes: Urea 11.47 mg/dl (IC+/- 1.72) y creatinina 2.41 mg/dl (IC+/- 1.06). No se encontraron diferencias estadísticas significativas entre hembras y machos, ni entre jóvenes y adultos. / 23 serum samples of añujes (Dasyprocta fuliginosa) raised under similar conditions were obtained in order to find the renal enzymes profile. The animals were captured and anesthetized by ketamin and xilacin. The serum levels of urea and creatinine were measured by colorimetrich methods using diagnostic commercial kits. The obtained values were the following ones: Urea 11.47 mg/dl (IC +/-1.72) and creatinine 2.41 mg/dl (IC +/-1.06). It was not found any significant statistical difference between females and males, and neither among young animals and adults.

Orientador: Francisco Leydson Formiga Feitosa / Banca: Alice Maria Melville Paiva Della Libera / Banca: José Jurandir Agliari / Resumo: Foram acompanhados 310 parturições de receptoras, com embriões fertilizados in vivo (FV) e in vitro (FIV) da raça Nelore, para determinar os índices de partos distócicos em receptoras meio sangue das raças Braford/Nelore, Hereford/Nelore, Simental/Nelore, Red Angus/Nelore, Nelore e anelorados, com idade entre três e seis anos, assim como avaliar o estado de saúde dos bezerros obtidos por intermédio de transferência de embriões, resultantes das técnicas de fertilização in vivo (FV) ou fertilização in vitro (FIV). Observou-se a ocorrência de 38 partos distócicos (38/310) e oito abortos (8/310), dos quais cinco fetos eram oriundos da técnica de fertilização in vivo (FV) e três da técnica de fertilização in vitro (FIV). A taxa de mortalidade em animais neonatos foi de 3,4% (10/290). Os bezerros nascidos de partos distócicos mais duradouros, entre quatro e seis horas, apresentaram os maiores valores médios de freqüência respiratória. A temperatura retal foi mais elevada em animais nascidos de partos laboriosos do que naqueles nascidos de partos normais. / Abstract: Three hundred and ten parturitions of receivers were accompanied, with Nellore embryos fertilized in vivo (FV) and in vitro (FIV), to determine the indices of dystocic calving in Braford/Nellore, Hereford/Nellore, Simental/Nellore, Red Angus/Nellore, Nellore and Zebu crossbreed recipients cows, aged between three and six years, as well as, to evaluate health condition of calves obtained through embryos transfer, resulting from in vivo fertilization (FV) and in vitro fertilization (FIV) techniques. The occurrence of 38 dystocic calving (38/310) and eight abortions (8/310) were observed, in which five embryos were arisen by in vivo fertilization technique (FV) and three embryos by in vitro fertilization technique (FIV). In neonate animals, the mortality rate was 3,2% (10/310). Calves born by lasting dystocic calving, between four and six hours, presented the biggest average values of respiratory frequency. Animals born by laborious calving showed higher retal temperature than those born by normal calving. / Mestre
