Fertility and hatchability of Chicken eggs by genotype and egg weight

Abstract

An experiment was conducted to assess the effects of egg weight on hatchability a to evaluate hatchability between Fayoumi and Sonali breeds of chicken in Govt Poultry Farm,Rangpur at the year of 2018. Simple random sampling technique was employed to select 288 hatching eggs; 144 eggs from each parent stock of Fayoumi and Sonali breeds were set into the incubator. According to the finding,hatchability was highest for Fayoumi breed than Sonali breed. Breed difference has no significant effect on hatchability, though, there is difference in hatchability between the two breeds. Early embryonic death is highest for Fayoumi. This difference is statistically significant (p<0.05). Late death is highest for the Sonali breed. This is highly significant (p<0.01). Death after hatching is highest for the Sonali breed. Post hatch performance of chick is not affected by breed. Post hatch performance of chick was not affected by egg size. Finally, breeds having better hatchability, proper egg handling and nest hygiene were recommended
