ABSTRACT:
The purpose of this study is to determine the physicochemical characteristics and incubation parameters of eggs of four strains of local farmed laying hens. Five hundred eggs (500) of each strain, divided into five (05) random blocks of 100 eggs, were the subject of our experiment. The thickness of the White strain shell is greater than that of the other strains (p <0.01), but its width is significantly less (p <0.003). The weight of the shells of the Nouar El Foul and Naked-Neck strains are larger than those of the White and Yellow strains (p <0.004). The weight of the albumin strains of the Yellow and Naked-neck strains are significantly higher than those of the other strains (p <0.007). The average weight of one egg of the Blanche strain is less important (49g) than that of the other three strains (p <0.02). Fertility of the Naked neck strain (90%) is superior to the Nouar El Foul strains; White (70%) and Yellow (65%) (p <0.03). The hatching rate, though low (<50%), is higher for the Nouar El Foul and Naked-neck strains (50%) and lower for the Yellow strain (25%) (p <0.01). The embryonic mortalities of the Yellow and Naked-neck strain are similar (40%) and those of the Nouar El Foul (20%) and White (30%) strain are the least expressive (p <0.001).
