The objectives of this study were to evaluate Sprouted techniques by planting white corn seeds (Zea Mays L.) on four roughage mixtures of date palm leaves (Phoenix dactylifera L.) and potatoes peels waste (Solanum tuberosum). Twenty five desert male goats averaged (eighteen months old) 22.76 ±1.29 kg live body weight were divided randomly into five equal groups (5 animals each) to receive one of the following experimental roughages R1: alfalfa (Medicago sativa) hay (control), R2: 75% potatoes peel waste (PPW) + 25% date palm leaves (DPL), R3: 50% potatoes peel waste (PPW) + 50% date palm leaves (DPL), R4: 25% potatoes peel waste (PPW) +75% date palm leaves (DPL) and R5: 100% date palm leaves (DPL). Goats were used in feeding trial lasted about fourty five days. The metabolism trial was conducted after the feeding trial to get the most nutritious sprouts green fodder (SGF) with concentrate feed mixture (CFM). Results showed that sprouting corn seeds on potatoes peel waste (PPW) and date palm leaves (DPL) as a media had increased CP, EE, C.CHO and ash contents while decreased OM, CF, NDF and ADF contents as compared with none sprouted media. Sprouted corn seeds on PPW or DPL revealed a significant (P≤0.05) improvement in digestibility coefficients of DM, EE and C.CHO. Nutritive values expressed as TDNg/Kg B.W. and DCP% increased significantly (P≤0.05) in sprouted mixtures as compared with control (R1). Goats fed R3 had (P≤0.05) lowest total feed intake and highest digestibility coefficients of DM, CP, EE, C.CHO and DCP. Also, goats fed the treated mixture R3 retained higher (P≤0.05) nitrogen values and nitrogen intake comparable with other studied groups. Goats fed sprouted mixtures had improved (P≤0.05) values of total water intake and decreased urinary water execration. Sprouted corn seeds had improved Na and K balances (g/kg BW) as compared with control group (R1). Goats fed sprouted mixtures had significantly higher (P≤0.05) values of total volatile fatty acids (VFA), ruminal ammonia (NH3- N), serum total proteins, albumin, globulin, urea and creatinin compared with control group. In conclusion we can produce green fodder by utilizing dried potatoes peel waste (PPW) and date palm leaves (DPL) as a media mixture (50% PPW and 50% DPL) by simple methodology using sprouts corn without any harmful effect on desert goats under dry season. |
