An experiment was conducted to study the comparative feeding value of locally produced vegetable protein cakes such as soybean oil meal (44%) (S.B.O.M.), rapeseed oil meal (R.O.M.), perilla oil meal (P.O.M.), sesame oil meal (S.O.M.) and corn gluten (50%). Three hundred broiler chickens were used for 8 weeks feeding trial and successive metabolic tiral. Results obtained are as follows; 1. Weight gains were significantly (P$lt;0.01) different among treatments showing the best gain in S.B.O.M. group and then P.O.M., R.O.M., corn gluten and S.O.M. group in that order. Feed intake showed same trend as weight gain did. For the feed efficiency, S.B.O.M. group was significantly (P$lt;0.01) superior to the other groups and S.O.M. group was significantly inferior to the other groups. Among the groups of receiving R.O.M., P.O.M. and corn gluten, differences were not significant each other in feed efficiency. 2. Amino acids compositions of R.O.M. and S.B.O.M. were better than that of other protein feeds considering their relatively high E.A.A. Index of 76.32 and 76.21 respectively. P.O.M., S.O.M. and corn gluten were low in lysine content while methionine contents were relatively high. 3. Nitrogen corrected M.E. values of S.B.O.M., R.O.M., P.O.M., S.O.M. and corn gluten were 2,367㎉, 843㎉, 2.234㎉, 1,305㎉ and 4,283㎉, respectively. Rates of nitrogen retention of P.O.M., S.B.O.M., R.O.M., corn gluten and S.O.M. were 59.38%, 51.18%, 54.11%, 44.80%, and 36.01%, respectively. 4. Dry matter and crude protein availabilities of finisher diet of R.O.M. group and S.B.O.M. group were higher than that of other groups but not significantly different. On the contrary however, crude fat availabilities of R.O.M., and S.B.O.M. group were significantly (P$lt;0.01) lower than that of other groups. 5. Thyroid gland weights and total serum cholesterol contents were significantly (P$lt;0.05) different among treatments. However, the relationship between thyroid gland weight and cholesterol content was observed only in R.O.M. group. Corn gluten was verb effective to increase skin pigmentation. 6. Production cost for 1㎏ of broiler meat of S.B.O.M. group was lower by about 20 won to 30won than that of R.O.M., corn gluten, or P.O.M. group, and by about 100won than that of sesame oil meal group which was least for the performance among the treatments.
