Popis: A total of 72 local turkeys comprising 24 Toms and 4 hens were used for the study. The males were randomly divided into two groups; M1 and M2. Group M1 males were intensively managed and fed 17% CP and 12.6 MJ/kg Metabolizable energy breeder diet. Group M2 males were semi-intensively managed and subjected to free range management and given concentrates. The males in both groups were randomly divided into four groups and subjected to four ejaculation frequencies/treatments (once, twice, three times and four times) per week using abdominal massage technique. A total of 729 eggs were incubated, candled and analyzed for fertility and hatchability. The data obtained were subjected to analysis of variance in a 2x4 factorial arrangement in a Completely Randomized Design. Significant means were separated using Duncan's option of SPSS. The results obtained showed significant (p < 0.05) effect of ejaculation frequency and management system on fertility and hatchability in all the parameters measured. The number of fertile eggs (NF) was significantly (P< 0.05) affected by ejaculation frequency and management system. Once and twice per week ejaculation frequency produced the highest number of fertile eggs under M2. The number of infertile eggs was significantly (P
