Chemical composition and energetic values of some feedstuffs for swine

Abstract

Proximal, mineral and aminoacid analysis of crude protein digestibility coefficient (CPDC), digestible energy (DE) and metabolizable energy (ME) were determined for 21 feedstuffs for swine by metabolism assay. The method of total fecal collection was used. For both weight groups the average values expressed on a dry matter basis for CPDC (%) and DE (kcal/kg) were, respectively, 66.10 and 3487 cowpea bean (Vigna unguiculata); 78.16 and 3629 cooked cowpea bean; 69.43 and 3310 toasted cowpea; 71.45 and 3413, pigeon pea bean (Cajanus cajan); 81.60 and 3705 cooked pigeon pea bean, 76.31 and 3690 toasted pigeon pea bean; 76.22 and 3803 ground barley (Hordeum vulgare); 71.20 and 4117 integral rice bran (Oryza sativa L.); 70.43 and 3136 degreased rice bran; 46.44 and 2608 cottonseed bran (Gossypium hirsutum L.); 86.26 and 3953 soybean bran (Glycine max Merrill); 74.11 and 2928 wheat bran (Triticum sp); 69.43 and 2977 cattle meat-and-bone meal 81.72 and 4012 hydrolysed feather meal; 45.57 and 2202 confrey hay (Synphytum peregrinum); 89.08 and 4050 alcohol white yeast; 80.16 and 3713 alcohol black yeast; 84,28 and 4039 ground corn (Zea mays L.); 60.73 and 2818 malt sprouts with hulls. The DE and ME (kcal/kg) were, respectively, 6686 and 6807 for lecithin and 6694 and 6599 for soybean soapstock.
