- Abstract
This study evaluated the effects of pre-hatch thermal programming on hatching time and chick grade of crossbred chickens. A total of 200 fertile eggs were randomly distributed across four treatments, namely T0: Standard incubation at 37.5 ℃ throughout the entire 21.5-day incubation period (control), T1: Incubation at 37.5 ℃ with a temperature increased to 38.5 ℃ for 6 h/day from days 10 to 18, T2: Incubation at 37.5 ℃ with a temperature increased to 39.5 ℃ for 6 h/day from days 10 to 18, and T3: Incubation at 37.5 ℃ with a temperature increased to 40.5 ℃ for 6 h/day from days 10 to 18. Each treatment has five replicates, with 10 eggs in each replicate. Variables observed were hatching time and chick grade. Hatching time was categorized into three intervals based on hours post-incubation, including early (480–492 h), middle (492–504 h), and late (504–516 h). Chick grade were classified based on their body weight at hatching, including platinum (>37 g), gold (34–37 g), and silver (30–34 g). The results showed no significant differences (P > 0.05) among the treatments across all hatching phases, indicating that the treatments produced comparable outcomes. The range of hatching time in early, middle, and late phases were 60.00–64.00%, 8.00–14.00%, and 2.00–8.00%, respectively. Pre-hatch thermal programming also did not significantly (P > 0.05) affect chick grade. The range of chick grade in platinum, gold, and silver categories were 58.00–68.00%, 8.00–18.00%, and 0.00–4.00%, respectively. It could be concluded that pre-hatch thermal programming is a safe approach to be applied in crossbred chickens, which had no adverse effect on hatching time and chick grade.
