Genetic and phenotypic correlation coefficients of quantitative traits in two chicken genotypes

This study was carried out to estimate genetic and phenotypic correlations of morphometric traits a newly developed Nigerian poultry breed (FUNAAB Alpha) Noiler chickens. A total 300 unsexed day-old-chicks comprising 150 each the two genotypes were raised for eighteen weeks. Superior individuals (4 cocks 20 hens per genotype) from first phase selected based on weight constitute parents 100 birds genotype in second 12 Body weight, linear body measurements (body circumference, breast girth, thigh length, shank length wing length) taken weekly basis. Growth data analysed using Generalized Linear Model SAS least significant difference (LSD) test used separate means genotypes. Computed variances covariances (PROC MIXED DATA) correlations. Results showed that chicken had higher (p<0.05) 10 18 weeks with average 2079.55 g compared 1895.29 FUNAAlpha. Positive observed among interest both FUNAAlpha latter having correlation coefficients which ranged between 0.573 (TL x SL) 0.953 (BG BC) at week 12. Sexual dimorphism favoured male all measured. The implication these results is it important know effect trait actually being its other traits.
