2.4.5. Relative Organ Weight

The weight of the organs relative to 100 g BW of the TS were calculated based on the TS body weights recorded prior to necropsy and their absolute internal organ weights.

### 2.4.6. Histopathological Examination

All organs collected (lung, heart, liver, kidneys, adrenals, ovaries, testes, spleen, stomach and intestinal tract) were fixed in 10% formalin, sectioned and stained using hematoxylin and eosin (H&E) before microscopically observed for any pathological abnormalities.
