| Abstract: |
The usefulness of treefodder as a supplementary feed during the dry season has been well recognized traditionally. No attempts have ever been made to characterize them scientifically, those available, are often found incomplete and misleading. In this perspective, the Agricultural Research Station (Pakhribas) ARSP has evaluated a total of 264 different trees and shrubs (including 10 bamboo species) generally fed to and browsed by ruminants. The samples were collectedfrom east Nepal including the inner Terai, mainly during the dry winter season at the time the tree leavesform the major component of the diet mix. Fodder trees were characterized on the basis of the soluble carbohydrate (nitrogenfre e extractives, NFE), crude protein (CP) and their fractionates (these include rumen soluble protein, total available protein, rumen bypass protein and indigestible protein), digestibility which included digestible organic matter in dry matter (DOMD), organic matter digestibility (OMD) and neutral cellulase digestib;/ity (NCD). detergent fibers (modified acid detergent fiber, MADF), calculated metabolisable energy (ME),, polyphenolics (l.ignin and tannin) and mineral elements (major and trace). The paper critically examines the importance of the tree species on the basis of the laboratory indicators of quality and discusses their adequacy in support to ruminant nutrition. The likely consequences of the negative associative effect of nutrients including high levels of polyphenolics or mineral toxicities are discussed Animal experimentation studies on animal produc tivity and feed acceptability by various classes of ruminants on promisi ng fodder types are suggestedfo r future research. |
