Hatchability of broiler chicken eggs on total egg set

Abstract

An investigation was aimed at to evaluate the hatchability of broiler chicken eggs and its variation among the hatcheries. The study was carried out in different hatcheries located in Guwahati city throughout the whole year, 2011. Total seventeen numbers of established hatcheries were included for the study and the required information and data were collected from the hatchery owners using a set of structured interview schedule specially prepared for the study. The highest hatchability rate on Total Egg Set (TES) was found in Dynamic hatcheries (81.53%) and lowest hatchability was found in Shivam hatcheries (75.91%). From the overall observation it could be concluded that the mean hatchability in the hatcheries was 78.49%. The Analysis of variance for hatchability (%) of broiler chicken eggs on TES basis has shown highly significant difference between the hatcheries (P
