Algunos aspectos del valor nutritivo de alimentos venezolanos destinados a animales monogastricos


The chemical composition and in vitro digestibility (IVND) by pepsin and pancreatin of 13 feed resources found in Venezuela were investigated. The resources were grouped as: protein sources ( Phaseolus calcaratus Roxb; Earthworm meal, Eisenia foetida and Soyabean meal, Soja maxima L.), tree resources (Leucaena, Leucaena leucocephala; Mulberry, Morus alba and Trichanthera gigantea) and agro-industrial byproducts (rejects from sesame, Sesamun indicum L.; rice polishings, Oryza sativa; sweet potato foliage, Ipomoea batatas; sugarcane leaves, Saccharum officinarum; forage groundnut, Arachis pintoi; wheat bran, Triticum vulgare) and meal made from dried rabbit intestines. Levels of N ranged from 6.30% ( Phaseolus calcaratus) to 8.43% (soyabean meal). IVND values were 96.1% (soya), 88.7% (earthworm meal) and 89.7% ( Phaseolus calcaratus ). Tree sources had N levels between 4.20% (leucaena) and 3.12% ( Trichanthera gigantea) and IVND of 66.0% (leucaena) and 30.1% ( Trichanthera gigantea). Agro-industrial products had 1.15% N (sugar cane leaves) and 3.87% (wheat bran) and IVND of 79.4% (rabbit intestine meal and wheat bran) and 33.9% (sweet potato foliage). The levels of NDF were poorly related to IVND values (-0.38).
