Abstract
ABSTRACT In total, 806 eggs of free-range Hassawi indigenous chickens were collected from local farm in Saudi Arabia. Eggs were weekly collected for 11 weeks. Initial egg weight (IEW) was recorded, and eggs were graded into four classes (A: 35-40 g, B: 40-45 g, C: 45-50 g, and D: 50-55 g). Eggs were stored for seven days at 75-80% relative humidity and 14-16 C, after which egg weight losses (WL0) were calculated. During incubation, eggs were weighed on days 7 (W7) and 14 (W14), and egg weight losses on days 7 (WL7) and 14 (WL14), and total loss (WL0-14) were calculated. Hatchling weight (CW) was measured. The proportion of CW relative to egg weight loss (WL) on ...
