The oil meal and crude oil from kapok seeds (Ciba pentandra) are obtained as the by-product of kapok fiber production. The kapok oil meal contains 28-30% protein which can be used at low levels (7-10%) as protein supplement for animals. The results from chick and quail experiments revealed that 15% kapok meal, 6% crude oil or 10% kapok seeds in chick and quail rations caused suppression of growth, high mortality, less haemoglobin content of red blood cells, enlargement of liver and gall bladder. The abdominal fat become hard due to increased stearic acid and decreased linoleic acid content. Testis and ovary developments, egg production, fertility and hatchability were effected. The clyclopropene fatty acids (sterculic and malvalic acids) in kapok seeds may inhibit the conversion of oleic to linoleic acid and less stearate desaturase formation. Lipids of follical and sex hormones are involved in reproductive performances. Hemolytic anemia appeared due to the abnormality of red blood cell wall. Cause of death, liver and gall bladder enlargements are not given.
