Assessment of Indigenous and Crossbred Cattle Bull’s Seminal Characteristics

Abstract

The present investigation was undertaken on cattle bull semen reared at Frozen Semen Bull Station, Karimnagar, Telangana. The study was carried out on four cattle breeds (3 to 5 years of age) viz., Gir, Ongole, Jersey and Crossbred Jersey (CBJY). Semen was collected twice weekly from each bull using artificial vagina technique with a total of 32 ejaculates evaluated under study. The semen was diluted with Egg Yolk Tris Citrate (EYTC) extender and was evaluated for physical characteristics of neat semen, motility  arameters and sperm viability percentage. The investigation revealed that Gir bull semen had significantly higher (p<0.05) ejaculate volume, mass motility, individual motility, sperm concentration compared to other breeds in present study. Whereas, Jersey bull semen had significantly higher (p<0.05) sperm viability percentage.
