Title

Estimation heritability and genetic trend of some economic traits of Esfahan native fowls

Pages

  85-98

Abstract

 The aim of the this study were to estimate Heritability and performance of economic traits in Esfhan Native fowls. For this purpose, the collected data included 72785 records of 17 generations (1995-2015) were used. Genetic parameters were estimated by multi-trait animal model using WOMBAT software and breeding values were predicted for all birds. Also, a series of six different animal models were fitted for all traits, and the best model for each trait was chosen based on log-likelihood ratio tests (LRT). Results showed that Maternal effects are significant in all economic traits except egg number and egg weight at 1st day of laying and so, the inclusion of these effects in models, increasing the accuracy of the estimates of direct Heritability. Therefore, it must be taken in to consideration for future selections program, to analysis the traits under selection, by most appropriate model. The highest and lowest Heritability were estimated for body weight at 1 day of age (0. 56± 0. 01) and egg weight at 1st day of laying (0. 12 ± 0. 01), respectively. Genetic trends of BW1, BW8, BW12, ASM, WSM, EN, EW1 and MEW were estimated, 0. 07, 12. 35, 17. 36,-1. 36, 23. 40, 1. 06,-0. 03 and 0. 17 respectively, all of these traits were significant. Results of this study showed that there is a possibility of improving traits using appropriate methods of genetic selection.
