Female rabbits from the age of 9 weeks till age of maturity were reared in two separate groups under long (16L:8D) and short (12L:12D) photoperiods. Does reared under long photoperiod showed increased body weight and ovary weight body weight ratio as compared to does reared under short photoperiod. At 15 weeks of age Graafian follicles appeared for the first time in long photoperiod group while the same appeared in the short photoperiod group at 19 weeks of age. At pre-pubertal and pubertal age the serum concentration of FSH and LH were more in long photoperiod animals as compared to those of short photoperiod animals.

Abstract


Female rabbits from the age of 9 weeks till age of maturity were reared in two separate groups under long (16L:8D) and short (12L:12D) photoperiods. Does reared under long photoperiod showed increased body weight and ovary weight body weight ratio as compared to does reared under short photoperiod. At 15 weeks of age Graafian follicles appeared for the first time in long photoperiod group while the same appeared in the short photoperiod group at 19 weeks of age. At pre-pubertal and pubertal age the serum concentration of FSH and LH were more in long photoperiod animals as compared to those of short photoperiod animals.
