EFFECT OF REPLACING MAIZE WITH RMW AND SUPPLEMENTED WITH NCP ON CARCASS AND MEAT QUALITY OF BROILER CHICKENS
Abstract
This study evaluated the impact of replacing maize with rice milling waste (RMW) and
supplementing with nano calcium phosphate (NCP) on carcass and meat quality in broiler
chickens. Conducted at the Poultry and Research Unit of the Teaching and Research Farm,
Ladoke Akintola University of Technology, Ogbomoso, Nigeria, the experiment utilized RMW
sourced locally and synthesized NCP from breadfruit (Artocarpus altilis) leaf extract. A 2×3
factorial design in a completely randomized layout, with a control group, tested three levels of
RMW replacement (40% maize-based diet) and two forms of RMW. The study involved 280
Arbor Acres broiler chicks, divided into seven treatment groups with four replicates of ten birds
each. Data were collected on proximate diet composition, organ, and carcass characteristics.
Results indicated that dietary treatment significantly influenced (P < 0.05) spleen and abdominal
fat weights, with the control diet showing the highest abdominal fat (0.47%) compared to lower
values in treatments with RMW and NCP (0.05%-0.09%). Spleen weights were highest in the
control group (0.18%) and lowest in treatments with RMW and NCP supplementation. Overall,
replacing maize with RMW, supplemented with NCP, proved a feasible alternative in broiler
diets, providing a cost-effective maize substitute while addressing RMW's nutritional limitations.
These findings highlight RMW's potential to support broiler growth, particularly with enhanced
mineral bioavailability from NCP supplementation, although careful diet balancing is essential
