The information was collected using the snowball technique and using a formal questionnaire developed (AU-IBAR, 2015). The dominant plumage is pearl gray with a frequency of 38.89% followed by black (13.85%). In total, 154 adult animals were lost by operators with a frequency of 22.95%. According to plumage, white comes first with a frequency of 51.61% followed by Lavender plumage (36.58%). Predation is the major constraint with a frequency of 35.72%. The guinea fowl most targeted by predators are the white guinea fowl with a frequency of 56.25%, while predation is low for black plumage (25%), royal purple (33.34) and pearl gray (34.69). The pearl gray guinea fowl and the royal purple guinea fowl appear to have a more developed wild instinct, which explains the frequency of recorded escapes. White plumage is perceived as being more docile during breeding and tends to exhibit better resistance to heat stress compared to other phenotypes, making it more valued for traditional rituals. Dark plumage seems more sought after in breeding for its supposed prolificacy, its resistance to infections and its weight. According to breeders, the dominance relationship mainly depends on the number of individuals of the same plumage. Dark plumage in significant numbers in most flocks seems to have dominance in terms of food and choice of sexual partners, which would explain their large numbers.展开更多
