Role of feeding time and food amount in the reproduction of spotted Munia.
It was observed that food restriction significantly increase gonadal development for about two months indicating that hypothalamo hypophyseal gonadal axis becomes more sensitive to feeding stress during the early breeding period than the other reproductive phases. Normal testicular development was also not seen in the spotted munia in which food was restricted for two times each of 3 hour duration, despite the fact that daily food consumption was not significantly less (only by 6.60%) compared to the control group. This suggests that daily restriction in feeding for a longer period (total 6 h or more) may also alter the reproductive function in wild birds.
