At the same time, effect of sex was studied. Under the conditions of this experiment, the following summary appears justified : 1. Protein source and energy level had no singificant effect on weights of blood, head, shank and toe, meat, abdominal depot fat, spleen, kidney, gizzard, lung and viscera. 2. Considering protein source and energy level, birds on the ration with fish meal showed higher dressing precentage (70.77%) than those on ration with feather meal (69.38%) at 5% level of probability. 3. Also when sex was disregarded, birds on high energy ration was high in percentage of eddible meat than those on standard energy ration (P\u003c.01); 50.69% and 49.44%, respectively. 4. No differences due to energy level in weight of liver, skin and abdominal depot fat were found. 5. Male showed higher (P\u003c.01) values than female in live weight and weights of blood, head, shank and toe, bone, heart, gizzard, lung, liver and viscera though no differences were found in dressing and eddible meat percentages. 6. Two way interaction of energy x sex was present in bone weight, though neither two way between protein and sex nor three way interactions existed in any criteria studied. Considering all these results, it can be said that addition of hydrolyzed poultry feather at the rate of 2 to 5% in the broiler ration seems to be feasible and that producers are able to replace some portions of grains with 4 to 8% of beef tallow without any adverse effects. Although male is more productive for a producer from view point of weight gain, no advantages for a processor are found since no differences were observed in rate of eddible meat and dressing percentages.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学農学部"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/4383"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
