Rearing photoperiod and egg composition: differential effects of LD 12 : 12 and long photoperiod (LD 18 : 6) in RIR hens


, : Rearing photoperiod and egg composition: differential effects of LD 12 : 12 and long photoperiod (LD 18 : 6) in RIR hens. Indian Journal of Animal Research 35(1): 1-9

The effect of a step-down photoperiodic manipulation on the physical features and chemical composition of the eggs of Indian Rhode Island Red (RIR) fowls was studied. 24 one-day-old pullets were divided into 2 groups. Group I was reared under a photoperiod of L:D 12:12 throughout the experiment (NLD). On the other hand, group II was reared under a long photoperiod of L:D 18:6 from day 1 to 90 post-hatch, which was shifted thereafter to L:D 12:12 (LP).
