DAG defect in Murrah buffalo bulls in Brazil
Dag defect sperms have an abnormal tail coiled morphology are totally or almost totally immotile and have severe abnormalities on the fibers in the axial filament. This defect in bovine was shown to be due an autosomal recessive gene. In the present study 23 buffalo bulls age 18-34 months examined f...

| description | Dag defect sperms have an abnormal tail coiled morphology are totally or almost totally immotile and have severe abnormalities on the fibers in the axial filament. This defect in bovine was shown to be due an autosomal recessive gene. In the present study 23 buffalo bulls age 18-34 months examined for BSE (Breeding Soundness Examination) showed sperm motility varied between 0 to 70% accomplished with 10 a 65% of sperm pathology with or not a predominance of strong coiled tails with or without persistence of droplet. In Brazil Murrah breed have had only eight female PO (pure of origin - India) gave origin of the herd and not more than four males where also imported from India, although in the last two decades some quantity of frozen semen were introduced in the country imported from India. As in the other domestic species inbreed seems to be the main cause of this abnormalities in different breeds. The knowledge and further study of such abnormalities is the only way to overcome a problem that if not controlled will tend to spread out without control causing in the future more problem for development of some herds. |
