The present investigation was carried out to investigate egg weight losses and hatchability of eggs of Kuroiler breed of chicken at poultry farm SKN College of Agriculture, Jobner (Rajasthan). Total 180 fresh eggs of Kuroiler chicken of 25-38 week age were collected for this study and stored for 0, 5 and 7 days at two different temperatures i.e. 30±2°C and 20±2°C as per treatment i.e. T1 (30°C+0d), T2 (30°C+5d), T3 (30°C+7d), T4 (20°C+0d), T5 (20°C+5d) and T6 (20°C+7d). Treated eggs tray are placed incubator to determine hatchability. Result shows that egg weight loss was maximum (2.06%) in treatment T3 followed by T2 and T1. The egg weight decreased with increase in storage duration and temperature conditions. In present investigation percentage hatchability (Fertile Egg Set Basis) was found significantly higher (90.70%) in 5 days stored eggs than 7 days storage (85.37%) and 0 day storage (77.50%) under cold temperature (20°C) with fumigation and hatchability of (Total Egg Set Basis) was found significantly higher in eggs that stored for 5 days (86.67%) and found lower in 0 days stored eggs (68.89%). Duration of storage and temperature significantly (P≤0.05) affected hatchability of eggs (both TES & FES). Hatchability declines when storage duration is beyond 5 days. Hatchability also found higher in eggs stored at 20°C temperature.
• Hatchability of eggs for 0, 5 and 7 days pre-incubation storage was found higher in 5 days (90.70%) storage eggs at the temperature of 20°C.
• Hatchability was also found higher at 20°C as compared to 30°C storage temperature.
