The objective of this work was to identify the best semen extender, the dilution rate and the storage time for rooster semen. A total of 60 roosters and 630 hens with 55 weeks of age were artificially inseminated, once a week, by six consecutive weeks, using .05 mL of semen/hen. The treatments were: T1=semen diluted with commercial extender-DC; T2 =semen diluted with Beltsville Poultry Semen Extender-BPSE; T3=semen diluted with Lake solution-LAKE and T4=pure fresh semen (Control). The dilution levels (D) […]
