| Abstract: | As guinea fowl age, their body weights and length of the esophagus and crop increased significantly, and relative length (cm x 100 g b.w(-1)) of the small intestine, caeca and total intestine decreased significantly (P < or = 0.05) in males and females. In addition, 52-week-old males had a significantly higher percentage length of rectum and heart weight, and females a significantly higher gizzard weight compared to 13-week-old birds. Compared to females, adult males differed significantly (P < or = 0.05) in the length of caeca and also in the proportion of the gizzard, proventriculus, heart and liver in total weight. |
