Studies on Liquefaction Time and Proteins Involved in the Improvement of Seminal Characteristics in Dromedary Camels (Camelus dromedarius)‎

Abstract EN

Semen was collected from six dromedary camels using artificial vagina during rutting season.

Liquefaction of the viscous semen occurred in 23.89 ± 1.49 h.

During liquefaction, proteins with molecular masses of 24.55 kDa and 22.07 kDa appeared in conjunction with the disappearance of intact 26.00 kDa protein after 18–24 h.

These proteins were identified as β-nerve growth factors (β-NGFs) in liquefied camel semen.

Guanidine-HCL improves the rheological characteristics of dromedary camel semen along with significant ( P < 0.01 ) increase in sperm motility.

No significant differences were found in viability of spermatozoa indicating no visible detrimental effects on spermatozoa.

The cause of semen viscosity, as well as proteins that are present in liquefied dromedary camel seminal plasma, is described for the first time.
