A Comparison On The Semen Characteristics And Extenders For Freezing Semen Of The Swamp, River And Crossbred Buffalo (Bubalus Bubalis)
A study was undertaken ( i ) to investigate and compare the effect of chromosome make up on semen characteristics of three buffalo genotypes , viz swamp , 2n=48 ; river 2n=50; and crossbred , 2n=49; ( ii ) to investigate the influence of climate on the semen characteristics of the three genotype...

| Summary: | A study was undertaken ( i ) to investigate and compare the
effect of chromosome make up on semen characteristics of three
buffalo genotypes , viz swamp , 2n=48 ; river 2n=50; and
crossbred , 2n=49; ( ii ) to investigate the influence of climate
on the semen characteristics of the three genotypes ; (iii) to
study the freezability of the semen of the three buffalo
genotypes using four different extenders .
Theresults showed that in general , the semen quality was
better i n the swamp buffalo as compared to the river type. Except for the semen colour, density, volume and spermatozoa
concentration , all the other semen characteristics of the
crossbred buffalo were inferior to that of the other two
genotypes . The lower mean values for mass activity,
progressive motility percentage , percent intact acrosome and
the higher incidence of total spermatozoa abnormalities in the
crossbred buffalo ( 2n=49) semen indicate that the odd number
chromosome complement of this genotype has an adverse effect
on its semen characteristics. |
