A total of
Thirty Nigerian indigenous genotypes of the domestic fowl, aged between 22-25
weeks were used to evaluate the biometry of male genitalia and internalorgan
characteristics.The result showed significant (p<0.05) effect of genotype,
on right epididymis weight with naked neck having a higher mean value of  0.17± 
0.60g and normal feather with least value of 0.14± 0.03g. The paired vas
deferensweight was significantly higher for frizzle feather (0.90± 0.12g. lower
in normal feather (0.67± 0.24g) and naked neck (0.64± 0.15). The left testis
length was significantly higher (3.83± 1.13cm) in normal feather and naked neck
(2.83± 0.20cm) and least in frizzle feather (1.93± 0.38cm) .The left testis
length follows the same trend. Significant effect of genotype was not observed
on paired testes weight, Testis volume, epididymal lengths and vas deferens
lengths. No significant (P>0.05) effect of Genotype was observedon absolute
weights of heart, lungs and kidney; but significant effect (P<0.05) was
found on relative weights of spleen, lungs and liver.  The study provide baseline data for Nigeria
indigenous genotypes of domestic fowl  in
the southern guinea savanna region which may be useful for future studies and
breeding programmes aimed at genetic improvement of the reproductive
performance of local chickens in Nigeria.


Keywords: Genotypes, naked neck,
