FEED RESOURCES FOR POULTRY PRODUCTION IN ASIA AND THE PACIFIC .2. PLANT PROTEIN-SOURCES

The availability of soyabean meal for animal feed use in Asia and the Pacific is low. The potential usefulness of a wide variety of protein-rich plant materials which could replace soyabean meal in poultry feed formulations is examined in this review. These materials are classified into four groups: oilseed meals; grain legumes; green meals and miscellaneous. Their nutritional values are discussed with reference to amino acid profiles. The presence of anti-nutritional factors and the resulting constraints on their use are also considered.
