Summary
This study investigates the potential of enzyme-supplemented cassava peel and maize cob mixture as a low-cost, agro-industrial by-product feed for grower pigs, with particular focus on how such dietary modification influences tissue lipid and fatty acid composition. The use of exogenous enzymes is likely intended to improve digestibility of fibrous substrates that would otherwise limit nutrient availability in non-ruminants. The findings may have relevance to smallholder pig production systems in sub-Saharan Africa seeking to reduce reliance on conventional feed ingredients such as maize grain and soybean meal.
UK applicability
This study is conducted within a West African smallholder or peri-urban livestock context and has limited direct applicability to UK pig production systems, where feed ingredients, regulatory frameworks, and welfare standards differ considerably. However, the underlying principle of enzyme supplementation to improve utilisation of fibrous by-products in swine diets is of broader scientific interest to UK researchers working on feed efficiency and circular food systems.
Key measures
Tissue lipid content (%); fatty acid composition (% of total fatty acids), including saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA); feed conversion efficiency (inferred)
Outcomes reported
The study measured lipid and fatty acid profiles in the tissues of grower pigs fed diets incorporating cassava peel and maize cob mixtures supplemented with exogenous enzymes. It likely reported effects on saturated, monounsaturated, and polyunsaturated fatty acid concentrations relative to control or conventional diets.
