Abstract
The effect of processing on nutritional values of Delonix regia seeds incubated with Pennisetum purpureum in terms of proximate, mineral, anti-nutritional compositions, gas production characteristics, methane production, predicted metabolizable energy, organic matter digestibility and short chain fatty acids production were determined. Five treatments ( T1, mixture of soaked Delonix regia seed and Pennisetum purpureum; T2, mixture of raw Delonix regia seed and Pennisetum purpureum; T3, mixture of roasted Delonix regia seed and Pennisetum purpureum; T4, mixture of boiled Delonix regia seed and Pennisetum purpureum, T5 ( 100% Pennisetum purpureum which serves as control ) were allowed. In vitro gas production techniques for 24 hours were used to determine the nutritive value of processed 50% Delonix regia seed and 50% Pennisetum purpureum. The crude protein ranged from 13.38 to 15.71g/100g DM among the treatments while crude fibre was between 20.10 and 21.40g/100g DM, ether extract ranged from 1.90 to 3.12g/100g DM and ash 7.77 to 12.34g/100g DM. Calcium ranged from (2.34 - 3.61%), magnesium ranged (2.90 – 3.48%), sodium (2.05 – 2.91%) and phosphorus (0.88 – 1.12%). It was observed generally that the raw recorded the highest among the treatments while the values obtained for the heat treated seeds were lower than the raw. Oxalates ranged between (0.23% - 0.32%), phytates (0.29 – 0.43%), tannin (0.03 – 0.08%) and saponnin (0.36 – 0.49%). Methane ( ml/200mg DM ) production indicated T3 ( 50% roasted Delonix regia seed and 50% Pennisetum purpureum ) was highest. The potential gas production ‘a+b’ ranged from 12.33 to 28.33mL/200mg DM ). The highest potential gas production ‘a+b’ value of 28.33mL/200mg DM was obtained in T1 compared to other dietary treatment. Dry matter digestibility (DMD) ranged between 70.23 – 91.02% while the rate of fermentation was between 0.51 and 1.18ml/hr. The rate of fermentation was directly proportional to dry matter digestibility ( DMD ); the soaked recorded the highest value. Processing enhanced the nutritional contents of Delonix regia seeds. The result obtained shows that there were significant differences (p<0.05) among the treatments which indicated that T1 (50% soaked Delonix regia seed and 50% Pennisetum purpureum ) has the highest value of Metabolisable Energy (ME), Organic Matter Digestibility (OMD), Short chain fatty acids ( SCFA ) have the potential benefit which can be used as supplement for ruminant feeding during dry season.
