The birds with mating ratio of 1:4 and 1:5 had significantly (P<0.01) higher fertility (81.05, 75.89%), total hatchability (73.68, 62.50%) and fertile hatchability (90.91, 82.35%). Hence it is concluded that mating ratio of 1:4 and 1:5 may be optimum for guinea fowl birds reared under intensive system of management as they had good fertility, hatchability and low embryonic mortality.enArticle
