Abstract: Bratte, L., Ikhimioya, I. and Arijeniwa, A. 1997. Reproductive performance in relation to parity in Yorkshire x Landrace pigs reared intensively in the humid tropics of south-western Nigeria. J. Appl. Anim. Res., 12: 197–202. Data from 326 farrowings were used to study the relation between parity in the dam and reproductive parameters in intensively reared Yorkshire x Landrace pigs in the tropical rain forest zone of south-western Nigeria. Parity of the dam significantly (P>0.05) affected litter size at birth and number of liveborn piglets per litter, both of which increased progressively from 7.64±0.41 and 7.19±0.41, respectively, in gilts to 11.95±0.31 and 11.53±0.36 in 6th parity sows. The duration of farrowing and incidence of stillbirths were uninfluenced by parity. Litter size and number of liveborn piglets per litter were positively and significantly correlated with parity while the incidence of stillbirths was positively associated (P>0.01) with duration of farrowing in gilts and negatively related to the number of live bom piglets in sows. All other relationships were not significant.
