DOMINGUEZ REBOLLEDO, Alvaro et al. Fertility in hair sheep inseminated with freeze spermatozoa rediluited with seminal plasma. Rev. Cient. (Maracaibo) [online]. 2007, vol.17, n.1, pp.73-76. ISSN 0798-2259.

The objective of this study was to determine the spermatozoa viability of the frozen semen rediluted with seminal plasma through the fertility of 146 hair sheep inseminated cervical and intrauterine way. The fertility was measured in two times; return to estrus to the 17 days postinsemination and pregnancy diagnostic by ultrasound scanning to the 45 days postinsemination. The data of fertility were analyzed by means of the Chi-Square test. The obtained results showed that the addition of the seminal plasma in the semen fresh does not improve the fertility (P>0.05) obtained cervical and intrauterine way, on the contrary, the semen frozen rediluted with seminal plasma, so much in its cervical application as intrauterine, improvement (P<0.01) the fertility in a 41% and 50%, respectively to the 17 days postinsemination, results that persist to the 45 days of gestation. The results permit to conclude that the rediluted of the frozen semen with seminal plasma provides a greater recovery of the spermatozoa damaged by cold shock, which it is seen reflected in a greater percentage of fertility
