Abstract

Data on live performance traits obtained from experiments involving two strains of meat-type chicken were analysed and used to estimate heritabilities of the traits and the -inter-character correlations. There were strain differences (P<0.05) for body weight of birds to 56 days of age, average daily gain, and daily feed intake per bird. Strain differences were not significant (P>0.05) for feed conversion ratio. Genetic correlations obtained between pairs of characters were generally high (P<0.01). Coefficients of phenotypic correlation were slightly lower relative to those of the genetic correlation. Environmental correlation coefficients were moderate to high (0.36 to 0.99) and also significant (P<0.01) within strains. Correlation of feed conversion rate with other characters wert negative for the two strains, Heritability estimates for the growth traits wa very high, and no appreciable differences were observed between the strains.
