The influence of great number of genetic and environmental sources of variability has been studied on the variety of the volume the motility, the concentration of spermatozoa and the number of nonmotile spermatozoa of 2905 fresh ejaculates from buffalo bulls.The months have influenced the variety of the volume, the motility and the concentration; the years have influenced the volume, the motility and the number of nonmotile spermatozoa.The age variability has been mathematically proved regarding the motile and nonmotile gametes.Out of the climatic factors, the influence of the atmosphere pressure on the volume and the maximum temperatures on the volume and the nonmotile spermatozoa has been significant.
