Age- and sex-based variation in helminth infection of helmeted guineafowl (Numida meleagris) with comments on Swainson's spurfowl (Pternistis swainsonii) and Orange River francolin (Scleroptila levaillantoides)

“…Davidson et al (1977) reported that juvenile ruffed grouse (Bonasa umbellus) in the United States had higher intensities of infection than adults, whereas Moore et al (1987) showed that there was no significant difference between age or sex regarding intensities of infection in bobwhite quail. Little et al (1993) also found no significant difference between age and sex classes in the prevalence of helminth infection in greywing francolin. This study conforms with Crowe (1977) in that first-year guineafowl had higher intensities of infection than adults but, unlike Crowe's (1977) findings, female guineafowl in this study had significantly higher intensities of infection than males.…”

“…Saayman (1966) also found low incidence of insects in guineafowl diet during winter. Additionally, Little et al (1993) showed that cestode infection in greywing francolin (Scleroptila africanus) was lowest in winter and also attributed this to their seasonally variable diet.…”
