Résumé

This Study Investigated the Effect of Chilling and Freezing on the Sperm Viability and Functional Integrity of FUNAAB Alpha (Normal feather) chicken semen. Pooled semen collected from ten FUNAAB Alpha (Normal feather) chicken were diluted with Tris –based extender. Diluted semen was divided into two fraction, the first fraction was subjected to chilling at 4o c and the second fraction was subjected to freezing at 1oC for 24hrs. Thereafter semen were evaluated for viability and functional integrity. The result showed a consistent variation in the semen viability and functional integrity. However, Sperm motility and livability preserved at 4oC was significantly higher (p<0.05) than those preserved at 1oC. Abnormal sperm (head, mid piece and tail) recorded for those preserved at 4oC was significantly lower (p<0.05) than those preserved at 1oC. The findings indicate that sperm viability, functional integrity of FUNAAB Alpha (Normal feather) chicken were better preserved by chilling compared to freezing method.
