Note: ¹The abbreviations 33% IF, 50% IF, 67% IF denote feed for 2 consecutive days at 3-day interval, 2 consecutive days at 4-day interval, 1 day at 3-day intervals
²Means (±SE) within the same row followed by the different letters are significantly different (P < 0.05)
³MRR is the abbreviation for the maximum reproductive rate
N_AL = 23, N_33%IF = 27, N_50%IF = 34, N_67%IF = 37
