The determination of hematologic parameters for jundia´Rhamdia quelen cultivated in ponds is an easy and useful tool for the control of their sanitary and nutritional conditions. In the present work hematologic indices (RBC, WBC, Ht, Hb, MCV, MCH, MCHC), electrolytes (Cl, Na, K, Ca, Mg, P), metabolic products (creatinine, urea, ammonia, glucose, total protein, triglycerides, cholesterol, bilirubin) and enzymes (alanine and aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase) were measured in a population of jundia´. The mean ± SEM and range were established.

This study investigated the composition of milt of the South American silver catfish (Rhamdia quelen) or jundia´. The semen was taken from jundia´in different periods during the four seasons. The biochemical composition of seminal fluid and the characteristics of sperm were analyzed. The semen quantity which can be extracted per fish in one day was 0.95±0.08 ml during spring (maximum) and 0.24±0.03 ml during winter (minimum). Sperm density (spermatocrit) showed higher values in the spring (75.1±1.3%) decreasing slightly afterwards and reaching 63.0±2.4% to 65.0±2.2% in the fall and winter. Immediately after water dilution, 90-100% of the spermatozoa presented vigorous straightforward motility that remained for at least 20 s. The total duration of the motility was 47.9±1.3 s in the spring and 38.6±0.6 s in the other seasons (P < 0.05). This pattern of motility is maintained for more than 2 h after storage of the milt at room temperature. The pH from 5 to 10 of the water dilution does not influence the sperm motility. The mean seminal pH and osmolality values were 8.7±0.07 and 274.8±11.2 (mOsm/kg), respectively. The ion concentration was: Na 153.7±2.4, K 10.7±2.4, Cl 139.4±2.1, Ca 4.2±0.2, Mg 0.9±0.05, P 0.9±0.08 (mEq/l). The total protein was 0.6±0.05 mg/dl and cholesterol concentration was 13.9±0.9 mg/dl.

RESUMOForam avaliadas 24 gatas, hígidas, sem raça definida, distribuídas em três grupos de oito animais. Descreveu-se o acesso laparoscópico para ovariossalpingo-histerectomia (OSH) e comparou-se o uso do eletrocautério bipolar (grupo I), do clipe de titânio (grupo II) e da ligadura com fio de sutura (grupo III) para a oclusão dos vasos ovarianos e uterinos. Hemorragia e enfisema subcutâneo foram as principais complicações observadas no transoperatório e hematoma subcutâneo e deiscência de sutura, as do pós-operatório. O procedimento cirúrgico e a técnica operatória mostraram-se viáveis nos três grupos. O uso do eletrocautério bipolar apresentou vantagens na comparação com os outros métodos de hemostasia.
