Abstract
The biological value of 5 mushroomsChlorophyllum molybditis, Psathyrella atroumbonata, Termitomyces robustus, Termitomyces striatus andVolvariella esculenta from our collection of wild edible mushrooms were determined using weanling rats.C. molybditis supported rapid growth with PER (2.63) higher than the casein control (2.50).P. atroumbonata was average in biological performance (PER 1.50) whileT. robustus andV. esculenta did not support growth at all. Rats onT. striatus dried at 60°C for 48 h lost weight rapidly and showed pathological signs of toxicity by the second day. All rats on this died died by the fourth day of the experiment. When the diet ofT. striatus dried at 90°C for about 8 h was fed, the rats gained weight marginally but all survived. Prolonged storage ofT. striatus at 60°C for 5–8 weeks also seemed to detoxify the poisonous component such thatPER andNPR values were 0.8 and 2.0 respectively. 2 pairs each of adult rats fedC. molybditis andTricholoma lobayensis diets for 10 days were mated. Rats ofC. molybditis diet gave 5 and 6 litters each and only one of these litters seemed to have retarded growth. Rats onT. lobayensis diet did not produce any litters for 14 weeks but the female produced off-spring when mated with control male rats.
