| Title : | PHENOTYPE CORRELATION BETWEEN PRODUCTION TRAITS AND BODY WEIGHT OF HEAVY BROILER BREEDER HENS |
| Abstract : | Research was conducted on two broiler parent flocks of Ross 308 and Cobb 500 hybrids. At the beginning of productive cycle (24 weeks of age) for Ross 308 hybrid average body weight of laying hens was 2680.40g, while for Cobb 500 hybrid it was 2697.80g. In the middle of the productive cycle (42nd week) body weight was 3565.10 g (Ross 308) and 3599.05 g (Cobb 500), while at the end of productive cycle (61st week) body weight for Ross 308 hybrid was 3841.50 g, and for Cobb 500 3850.00 g. Determined differences in body weights of laying hens in specific periods of productive cycle (17.40 g, 33.95 g and 8.50 g), as well as difference in weight for entire productive period (23.26 g) were not statistically significant (P>0.05). More thorough research of broiler laying hen body weight influence on productive performances was done by determining phenotype correlation coefficient between researched parameters. Therefore between hen body weight and most of productive parameters statistically significant (P<0.001; P<0.01; P<0.05) phenotype correlation coefficients were determined, while between body weight of laying hens and laying intensity of breeding and fertilized eggs determined correlation coefficients were not statistically significant (P>0.05). |
