N2  - Thr chemical and nutritional nature of oil and protein as found in rubber seeds is reported. The raw dehydrated seed contains about 17.6 per cent protein and about 36.7 per cent crude oil. The amino acid content of the protein was compared with that of other oil seed sources. It is observed that the amino acid content of the protein in rubber seed is deficient in lysine, sulphur amino acids and tryptophan. Extrusion cooking improved the protein quality of the product and also removed HCN from the seed. For feeding trials on rats the extruded product was fed full-fat or hexane extracted. Physiochemical characteristics of the oil showed that the oil has a high concentration of C18:2 fatty acids. Nutritive value of the oil was determined by rat growth performance. results indicated that when fed at a high level (20;) in the diet, it is toxic. At 10;level and for adult rats a digestibility of 84;was noted, which increased to 93;on heating. These values are slightly lower than those found for cottonseed oil. The results of the study shows that rubbr seed has potential in animal nutrition and in oil industry
