Comparative energy values of sorghum distillers waste, maize cob and shea butter waste for pigs.

Résumé

A balance trial aimed at determining the energy values of sorghum Distiller's wastes (SDW), Maize cob(MC) and shea butter waste (SBW) for barrows was conducted using a 4 X 4 Latin square cross-over experimental design. While feed intake was influenced (P<0.05) by the test feed ingredients, the weight gained was not significantly affected (P>0.05). Digestibilities of dry matter and gross energy (GE) as well as metabolizability of digestible energy (DE) were not influenced (P>0.05) influenced by the dietary treatment. The energy values (i.e GE, DE, uncorrected metabolizable energy (ME), and metabolizable energy corrected for nitrogen retention (MEn) determined for ingredients were different (P<0.05). DE values of 7.19, 6.73 and 15.54 Mj/kg DM;ME values of 5.90, 4.79 and 12.94 Mj/kg Dm were established for SDW, MC and SBW respectively. These ingredients have potentials as alternative low-energy feedstuffs in pig feeds.
