Abstract: A study was carried out with 48 Japanese quails (Coturnix coturnix japonica) at the poultry unit Department of Animal Science, Ahmadu Bello University, Zaria. The birds were individually caged and intensively reared for a period of 165 days to study the egg production pattern of the birds in terms of egg number, number of clutches, clutch size, number of pause, days pause and paused length; and also the association of each with egg number. It was observed that the 165 days egg production pattern characteristic of the birds were egg number 103 ± 15, number of clutches 38 ± 6, clutch size 3 ± 1, number of pause 38 ± 4, days pause 54 ± 14 and pause length 2 + 1. The level of variation for the measured characteristic over the period was in the range of CV values of 15 to 33% with the highest level of variability exhibited by clutch size. There was a significant (P = 0.05) positive relationship between egg number and clutch size (r = 0.85) but negatively related with number of clutches, number of pauses, days paused and pause length (r = -0.46 to -0.72). While number of clutches was negatively correlated with clutch size (P = 0.01; r = 0.84) it was positively correlated with the number of pauses and days paused (r = 0.82 and 0.51). The clutch size was positively correlated with number of pauses (r = 0.75) and negatively with days paused and pause length r = - 0.75 and -0.27). The number of pauses was positively correlated with days paused and paused (r = 0.35). This study has shown that Japanese quails commence egg production at 71%, attained a peak production of 86% which gradually decline to 57% by 165 days of age. Egg number was favoured by clutch size but negated by number of clutches, number of pauses, days paused and pause length. The age at peak production was 12 weeks (84 days) of age.
