1 SUMMMARY
Local chicken populations of Benin include North, South, Holli, Fulani
and Sahoue ecotypes. This study assesses the nutritional quality of
their meat. Two groups of 26 chickens of each ecotype were reared under
free range or confinement breeding systems, and slaughtered when 20, 24
and 28 weeks old. Breast and thigh-drumstick meats were used for
chemical and physico-chemical parameters composition analysis. The
results showed that the highest dry matter and protein contents were
recorded in Holli ecotype (P<0.01), whereas the highest fat content
was found in Fulani ecotype. The free range chickens showed the highest
protein content (P <0.001), whereas chickens from confinement
breeding had the highest fat content (P<0.05). Protein content was
higher in breast than in thigh (P <0.001), while dry matter, ash and
fat contents were higher in thigh meat than in breast meat (P
<0.001). The dry matter content decreased with age (P <0.001),
while the fat content increased (P<0.01). The highest protein
content of thigh and breast were obtained between 20 and 24 weeks old.
It can then be conclude that indigenous chicken meat is better at 24
weeks of age.
