Abstract: Data were collected on rabbits kept at the National Animal Production Research Institute Ahmadu Bello University, Zaria. The data were collected over 7 year period. The trait studied included average Litter Size at birth (LS), Average Birth Weight (ABWT), Average Weaning Weight (AWWT) and Gestation Length (GL). ABWT ranged from 46.67±4.05 to 52.84±2.94 in the late dry and early wet season, respectively. Average weaning weight and litter size were highest for rabbit born during the early rain period with a value of 12407plusmn;78 g and 5.18 kits, respectively. The highest average birth weight was recorded for kits born during the 3rd parity with a value of 51.4±3.65 g. The average weaning weight also follow a similar trend. Litter size was however highest for kits belonging to parity 4. AWWT and LS were significantly correlated with ABWT with a value of 0.22 and -0.43, respectively. The correlation coefficient of AWWT with LS and Parity were -0.14 and 0.32, respectively. All other correlations were small and non-significant.
