The present investigation was carried out to investigate hatchability of eggs of Kuroiler breed of chicken at poultry farm SKN College of Agriculture, Jobner (Rajasthan). For the study total 180 fresh eggs of Kuroiler chicken of 25-38 week age were collected and stored at different temperatures i.e. 30±2°C and 20±2°C as per treatment i.e. T1 (30°C + NF), T2 (30°C + F), T3 (20°C+NF) and T4 (20°C + F). Result shows that the hatchability (FES) was found higher (90.70%) at 20°C temperature and lower (83.33%) at 30°C temperature with fumigation. At same temperature 20°C, hatchability found some variation in fumigated group (90.70%) and non-fumigated group (88.10%) due to lower incidence of bacterial growth. There was nonsignificant difference of fumigation on mean percentage hatchability of fertile eggs. Storage temperature significantly (P≤0.05) affects the hatchability it found lower at 30°C than at 20°C. Embryonic mortality found lower (09.30%) in T4 and higher (17.07%) in T1 group. Embryonic mortality also affected by the interaction of temperature and fumigation. It is suggested that for higher hatchability eggs were stored at 20°C temperature and the eggs are necessary fumigate before the incubation for better hatchability results.

Highlights

• Hatchability (FES) was found higher (90.70%) at 20°C temperature and low (83.33%) at 30°C temperature with fumigation.
• Hatchability (FES) was found higher (90.70%) in fumigated eggs and lower (88.10%) in non-fumigated eggs.
• Embryonic mortality also observed in fumigated eggs.
