Abstract
Based on the official statistics of the industries and mines organization, about 7500 tons of wastes in chickpea processing plants are produced annually in the East Azarbaijan province of Iran. In order to determine chemical composition, anti-nutritional factors, and metabolizable energy of chickpea (Cicer arietinum L.) by-product (including chickpea pre-screening and chickpea hull), classified random sampling from 10 % of plants was performed first. Then amount of dry matter (DM), organic matter (OM), crude protein (CP), crude fibre (CF), ether extract (EE), neutral detergent fibre (NDF), acid detergent fibre (ADF), and antinutrient including total extractable phenolic compounds (TPC) and total tannin (TT) were determined. There were significant differences (P < 0.01) between chemical composition and antinutrient amount of chickpea by-product except for DM and OM. An in vitro gas production technique was used to determine the rate and extent of gas production and organic matter digestibility. Amounts of gas production were recorded at 2, 4, 8, 12, 24, 36, 48, 72, 96 and 120 h after incubation. Gas production rate constant and value calculated for OMD and ME of chickpea pre-screening were significantly higher than chickpea hull (P < 0.01), but the amount of b and lag time of chickpea hull were significantly higher than chickpea pre-screening (P < 0.01).
