Docosahexaenoic acid and phenazine ethosulfate are not efficient lipid modulators for porcine in vitro maturation systems.

The high lipid content in porcine oocytes impairs in vitro embryo production (IVP). Here, we evaluated the influence of two different lipid modulators during in vitro maturation (IVM) on the embryo development and the lipid content of oocytes and embryos. In Experiment I, oocytes were exposed to 50 μM docosahexaenoic acid (DHA) with (+) or without (-) the presence of porcine follicular fluid (pFF).

[Risk factors and prevalence of antibodies anti-Neospora caninum in urban and rural dogs from Rio Grande do Sul, Brazil].

Serum samples from 339 dogs from rural (beef and dairy farms) and urban areas of Municipality of Pelotas, RS, were tested by indirect fluorescent antibody test to verify the presence of antibodies anti-Neospora caninum. Data from dogs took part of an epidemiologic questionnaire to identify possible risk factors associated with the seropositivity. Antibodies anti-N.
