Forty-seven hybridprogenies from crossbreeding between the Nigerian indigenous pig NIP and Largewhite pigs were used. Body measurements and live weight were recorded weeklyfrom first week of birth to their weaning date. Body measurements taken wereBody Weight BW, Body Length BL, Body Height BH, Heart girth HG and Rumpcircumference RC of crossbred progenies. The correlation between thereproductive parameters and growth performance of hybrid pigs were establishedwith good management practice. The mean for weaning weight was 6.72 ± 0.02,birth weight 0.91 ± 0.13, litter size at birth 5.36 ± 1.87, litter size atweaning 5.29 ± 1.97, litter weight at birth 4.56 ± 1.57, total litter weight atweaning 33.91 ± 11.6, average daily weaning weight 0.73 ± 0.12, average littersize at birth 0.93 ± 0.11 and sex ratio 97.78% ± 8.61%. The male and femalemean values for weight of animals were 6.96 ± 1.0 and 6.52 ± 0.9 with maleheavier in weight and higher in morphometric traits such as body length, heartgirth and rump circumference, while the female were high in morphometric traitssuch as snout length, ear length and body height. The correlation matrix forbody weight against linear body measurements in pre-weaned NIP crossbredsindicates that all the parameters could be used to select for body weight. Thelinear equation generated by regressing body weight on snout length, bodyheight, rump circumference, heart girth and body length could be used byresource poor pig farmers in the estimation of body weight of pre weanedcrossbreds pigs if they cannot afford weighing scales.
