Abstract

There has been an increase in the number of pigs slaughtered worldwide due to population growth. Pig Hoof, a non-edible slaughter-house waste, disposal is generating concern for the authorities and utilizing this by-product which has remained hitherto unused is the thrust of this study. Pig hoof was collected from the slaughter house and analysed for its nutritional content according to standard method. Analysed parameters were Crude protein 83.09±1.46, Fat 1.04±0.01, Fibre 9.04±0.16, Ash 6.53±0.12 and metabolisable energy 3159.40±54.52 KJ kg-1. The essential amino acid profile revealed Leucine as highest 6.71 g/100g, Histidine least 0.89 g/100g and tryptophan was below detectable limit while the non-essential amino acid Glutamic acid was highest 13.02 g/100g and Cysteine 0.66 g/100g least. The macro mineral content of pig hoof showed that Magnesium 1.22±0.23%, Phosphorus 0.83±0.01%, Sodium 0.37±0.02%, Calcium 0.30±0.01%, Potassium 0.23±0.01% while the micro mineral content was highest in Iron 2310±5.19 mg/kg and least in Copper 7.55±0.35 mg/kg.
