چکیده

the objective of this study was to evaluate the importance of environmental and genetic factors affecting semen quality; sperm volume (sv), sperm concentration (spco), total sperm (ts), fresh sperm motility (fsm), total fresh motile sperm (tfms), post thaw sperm motility (ptsm), total post thaw motile sperm (tptms), number of produced payout (npp), number of fresh motile sperm in each milt ejaculation (nfmse), motility before and after the freezing (mbatf) and number of post thaw motile sperm in each milt ejaculation (nptmse). we used polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) in 83 bulls belonging to two progeny test centers. the bb genotype was omitted from analysis.season of collection had a significant effect on sperm volume (sv)(p
