| Popis: | Sex identification at day old and separate management of male and female birds is important milestones in the development of commercial strains of chicken. The aim of the present study is to evaluate hatchling egg loss as well as sex determination methods at day old and sexual dimorphism over 8 weeks in Nigerian local Chicken. A total of 360 eggs of Nigerian Indigenous Chicken (NIC) was used to investigate hatchling egg losses, Sex determination at day old and weekly linear measurements were taken on 100 randomly selected Nigerian local chicks.The NIC had high fertility (86.67%) and hatchability of 69.17%. The egg total weight loss and chicks’ weights were5.02 and 26.25g, respectively. The percentage hatching loss was 29.04%. The Japanese vent sexing of the chicks had higher (73.58%) percentage accuracy than feather sexing (62.26%). There were no significant differences between males and females in weekly body weight from 2-6 weeks of age. However, male chicks were significantly (p |
