Abstract

   

The estimation of acrosomal integrity is crucial for predicting the fertility of spermatozoa. The semen quality analysis  demands assessment techniques to be reliable, quick and easy to perform for routine application in semen station. A study  was conducted to assess the acrosomal integrity of Kangayam cattle and Salem Black goat using Giemsa stain and modified  Trypan Blue-Giemsa stain. For this procedure, 70 numbers of frozen semen straws of Kangayam bull and Salem Black bucks  were stained. The staining quality and acrosomal integrity were assessed at the interval of 3, 5 and 24 hours interval up to 5  days, and evaluated as acrosomal intact and non-intact spermatozoa. In Kangayam bull semen, the quality of the staining  was good and better in trypan blue – Giemsa stain than Giemsa alone but for Salem Black buck semen Giemsa showed  better staining quality than trypan blue – Giemsa combination. However, the working solution of Giemsa once prepared can  be used for 4 days but the trypan blue-Giemsa stain can be used for only 24 hours once prepared. Hence, stain is required  to be prepared on daily basis for routine semen evaluation in semen stations. As a conclusion trypan blue – Giemsa staining  method is recommended for better staining of acrosome in bull semen and Giemsa alone in Buck semen.
