Supplementary feeding of piglets in the maternity ward is essential for late weaning at 45 days. The objective of this study was to test the hypothesis that a solid diet could improve the zootechnical performance of piglets at weaning. Thirty-six piglets were divided between three sows: suckling piglets only fed milk by sow A (group 1, control); suckling piglets fed by sow B and receiving the starter feed between days 30–45 (group 2); suckling piglets fed by sow C and receiving both types of feed, prestarter at day 15 and starter at day 30 until day 45 (group 3). Individual weighing was carried out as soon as the prestarter feed was introduced on day 15, then on day 30, finally on day 45. At weaning, piglets fed both types of feed had higher (p < 0.05) live weights at 45 days of age (11.2 ± 2.5 kg vs 8.0 ± 1.7 kg), feed intakes (292 ± 45 g/d vs 134 ± 45 g/d) and average daily weight gains (206 ± 49 g/d vs 101± 30 g/d). In conclusion, solid feed significantly improved (p < 0.05) the feed intakes and growth rates of piglets by day 45. This study showed the need to distribute prestarter and starter feeds in farms enhancing late weaning. This practice opens up prospects for improving animal production performance in pig farming in tropical areas.
