Digestibilité comparée des rations contenant de la drêche ensilée des brasseries, du tourteau de palmiste ou des coques de cacao chez le porc en croissance finition au Cameroun
Three digestibility trials were conducted at the Institute of Agricultural Research at Nkolbisson in Yaounde (Cameroon) between 2001 and 2005 to determine the digestibility of diets containing graded levels of ensiled brewer's grains, palm kernel cake and cocoa pod husk in growing pigs. The results showed that the incorporation of increasing levels of ensiled brewer's grains, palm kernel and cocoa pod husk in the diets significantly decreased the digestibility of dry matter, gross energy and crude proteins. Digestibility coefficients of dry matter, gross energy and crude proteins, estimated by linear regression at a maximum level of incorporation of byproducts in the diets were 51.0, 61.0 and 72.0% for ensiled brewer's grains; 42.0, 47.3 and 60.0% for palm kernel meal and 37.1, 27.5 and 12.4% for cocoa pod husk meal, respectively. Brewers' grains had the highest digestibility, followed by palm kernel and cocoa pod husk.
