EFFECTS OF DIFFERENT EDIBLE OILS ON GROWTH PERFORMANCE, DIFFERENT ORGAN WEIGHT AND SERUM TRANSAMINASES IN RATS

Abstract

The effects of different edible oils on body weight gain, different organ weight and serum transaminases were studied on 25, one month old long Evans male rats during the period from 3 April to 28 May 2003. The rats were randomly assigned to one of five equal groups (n = 5) as A, B, C, D and E of which group A was considered as control and fed with rat pellets (ICDDR, B) and others were supplemented with oils as soybean (group B), palm (group C, coconut (group D) and mustard (group E) at a concentration of 7.5% with pellets for 8 weeks. The results revealed significant (p < 0.001) increase in weight gain of the non supplemented rats (control). The mean heart weight of the nonsupplemented rats (control) was significantly (p < 0.05) higher than those of the treated groups. The mean liver weight of nonsupplemented, coconut and mustard oils treated rats were significantly (p < 0.05) higher than those of soybean and palm oil treated groups. The mean kidney weight of the mustard oil treated rats was significantly (p < 0.05) lower than those of other treated and control groups. No significant differences (p < 0.05) were observed among the groups in respect to SGOT and SGPT activities.
