Abstract
A study was conducted to evaluate the effect of genotype. sex. age and
generation on carcass traits of four varieties of guinea fowl. Three hundreds and
twenty birds were distributed into four varieties White. Lavender, Chocolate and Pearl
guinea fowl were evaluated at 12. 16. 20 and 24 weeks of age. Percentages of
dressing were 68.2, 69.7. 70.1 and 71.0 % at 12. 16. 20 and 24 weeks of ages
respectively. No significant differences between 16 and 20 weeks of age were found
for the meat yield. the giblets. bone. dressing. heart. neck and leg percentages. Male
birds showed significantly meat yield. dressing and heart percentages (P<0.05).
Opposite trend was observed with abdominal fat. feather and giblets percentages.
Live body weight, meat yield and dressing percentages of birds in second generation
were slightly heavy. They were 832.2 vs. 1145.1 g. 53.1 vs. 58.3 % and 68.3 vs.
71.1% in the first and second generation. respectively. Phenotypic correlations were
obtained among carcass traits. age and organ weights as well as linear regression
coefficient for carcass weight on organ weights. The linear regression coefficients
were positive and significant for all organ traits except for spleen weight. Correlations
between the organ weights and body weight were positive. The present study
indicates that improved meat yield or the dressing percentages may be achieved by
selection for quick growth.
