Investigations were conducted on the nutritive value of sunflower seed oil meal (unhulled, solvent-extracted; crude protein 31%, crude fiber 21%). Experiment 1 was for sunflower seed oil meal as a replacement for soybean oil meal, and Experiment 2 was for sunflower seed oil meal as a replacement for rapeseed oil meal, perilla oil meal and sesame oil meal. 210 broiler chicks (120 chicks for experiment 1, 90 chicks for experiment. 2) of shaver Starbro line were employed for five weeks in broiler rations. The results obtained in experiment 1 and experiment 2 were as follows; 1. Chemical composition and amino acid content of sunflower seed oil meal was chiefly distinguished by high fiber content and a low lysine, phenylalanine, and tyrosine level in the protein and a moderately high level of methionine in comparison with soybean oil meal. 2. As the amount of sunflower seed oil meal was increased in the ○ progressively poorer growth resulted, especially a complete replacement of soybean oil meal with sunflower seed oil meal markedly decreased growth. But as one-third replacement of soybean oil meal with sunflower sued oil meal was not significantly different in body weight gain, feed consumption, and feed efficiency, sunflower seed oil meal may be used within the level of one-third soybean oil meal or 7.3%. Also the results showed that sunflower seed oil meal may be used as a replacement for rapeseed oil meal, perilla oil meal, and sesame oil meal. 3. The nitrogen-corrected metabolizable energy of sunflower seed oil meal was 2005 ㎉/㎏, when the practical basal diet was substituted by 20% levels of sunflower seed oil meal end it seemed that fiber content of sunflower seed oil meal affected dry matter metabolizability, but its metabolizability was slightly higher than rapeseed oil meal, perilla oil meal, and sesame oil meal except soybean oil meal. The percentage of nitrogen retention of sunflower seed oil meal was higher than any other oil meals. 4. It was found that the weight of thyroid glands was not affected by the increasing level of sunflower seed oil meal, and the weight of thyroid glands of rapeseed oil meal was higher than any other oil meals, while the scores of skin pigmentation were not significantly different among various oil meals.
