ABSTRACT

During incubation, water loss and chick yield are the two most crucial variables. The purpose of this study was to look into how water loss and chick yield were affected by the age-wise incubation profile. Eggs from Ross-308 breeders were gathered for this experiment, and the breeders’ ages were used to split them into four groups, each of which had an identical number of eggs (n=538560 eggs). A Young (24–31 weeks), B Prime (32–50 weeks), C Old (50+ weeks), and Group D (control), and are the four groups. The setting machine was left incubating for 456 hours (19th day) for groups A, B, and C, and for 449 hours (18.7 days) for group D, which was the control. Fertility of eggs was performed through candling and shifted to hatchers for the next 50 hours for A, B, and C while 56 hours for D. Group B showed significantly better P<0.05 (89.02±0.41) as compared to A and C which are significantly P<0.005 same (88.66±0.33), (88.80±0.65) than D (control) (86.25±1.22) in term of hatchability. Excellent performance in terms of chicks yields C Significantly P<0.05 remains the same (69.28±0.54) as compared to A (69.17±0.54) and B (69.99±0.54), While high yield was recorded for D (71.45±0.54). Dead in the shell (DIS) was significantly the same for A (6.18±0.29), B (6.20±0.37), and C (6.13±0.60) than D (7.70±0.67) which contain higher DIS percentage. In terms of eggs, water loss was significantly the same for A (11.93±0.26), B (12.24±0.26), and C (12.31±0.26) which was recorded as ideal then D (10.16±0.26) which contained low water loss percentage. Groups A, B, and C were better as compared to D but overall group B was significantly better which means the eggs from different ages of birds require different conditions of incubation.
