Abstract

The study was couducted to determine the difference of heritability of Heterakis gallinarum in local and Lohman chicken. Sixteen local chicken and 16 Lohman chicken were inoculated with infected egg of Heterakis gallinarum for 250 egg in ech chicken. All chiken were necropsed 3 months after inoculated. The heritabilty of the worm was evaluated by determinan the number of infected chicken and number of worms.
