Abstract

Germinated paddy rice (GPR) was examined for its potential as a feed ingredient in comparison with paddy rice (PR) without germination. The attributes related to the chemical composition, phytochemicals, thermal property, nutrient digestibility and ME value were evaluated. It was found that GPR samples contained 7.48% CP, 1.96% EE, 67.58% NFE and 12.55% crude fibre on an air-dry basis. The gross energy, 3.77 kcal/g, was found to be close to that of corn. Germinated paddy rice showed slightly lower ash, NFE and GE but higher CP, EE and CF than those of PR. The GPR exhibited high content of phytonutrients especially gamma-aminobutyric acid (GABA) and this enhanced its antioxidant activities. Germination was found to alter gelatinization temperature as evidenced by the thermal property. The true digestibility and ME values were evaluated using eight 1-year old male White Tail Yellow chickens housed in individual cages. The results revealed the true digestibility values of CP, EE and CF as 35.41, 61.35 and 46.26 per cent, respectively. Apparent ME (AME) and true ME values were 3.20 and 3.28 kcal/g on an air-dry basis, respectively. It is concluded that GPR could be a good alternative source of feed ingredient for poultry.
