Abstract

This study was undertaken to determine the chemical composition of six common peels fed to ruminants namely: Irish potatoes (Solanum tuberosum), watermelon (Citrullus lanatus), sweet orange (Citrus sinensis), cucumber (Cucumis sativus), pineapple (Ananas comosus), pawpaw (Carica papaya) and lettuce (Lactuca sativa). These were purchased from fruit and vegetable retailers in Jos, Plateau State. The results for proximate composition are as follows: dry matter ranged from 95.75% (pawpaw peels) to 96.25% (watermelon rind), carbohydrate from 41.95% (pawpaw peels) to 45.70% (cucumber peels), fibre from 6.07% (cucumber peels) to 7.65% (pineapple peels), protein from 25.46% (sweet orange peels) to 26.66% (watermelon rind), lipid from 3.01% (lettuce) to 4.00% (watermelon rind) and ash from 13.97% (cucumber peels) to 16.71% (Irish potato peels). For antinutrients, saponin ranged from 0.867% (cucumber peels) to 2.53% (watermelon rind), tannin from 5.09% (cucumber peels) to 6.37% (lettuce), phytate from 0.003mg/100g (sweet orange peels and pawpaw peels) to 0.007mg/100g (watermelon rind), oxalate from 1.08% (cucumber peels) to 2.43% (watermelon rind) and flavonoid from 3.66% (Irish potato peels) to 4.37% (cucumber peels). Also, crude fibre fractions which include cellulose ranged from 10.81% (watermelon rind) to 12.02% (pineapple peels), hemicellulose from 7.73% (watermelon rind) to 9.24% (cucumber peels), NDF from 10.72% (lettuce) to 12.13% (sweet orange peels), ADF from 7.63% (Irish potato peels) to 9.13% (sweet orange peels) and ADL from 1.71% (cucumber peels) to 2.13% (watermelon rind).All parameters under proximate composition were significantly affected except protein, all parameters under antinutrients were significantly affected except phytate and flavonoid, and all parameters under crude fibre fractions were significantly affected (P<0.05). The selected samples are recommended for ruminant feeding at permissible levels or quantities.
