摘要
采集贵州有代表性的3个杜仲产区7月份杜仲叶样品,采用概略养分分析法比较分析CP、EE等营养成分含量,并采用活动尼龙袋技术比较研究主要营养成分在肉猪体内的消化率。结果表明:不同产区杜仲DM、CP、EE、CF、OM、Ca、P、Lignin、NDF、ADF含量分别在(33.67±2.08)%^(44.24±1.04)%、(12.22±0.65)%^(13.56±0.74)%、(5.47±1.14)%^(7.91±0.82)%、(6.87±1.48)%^(8.42±0.75)%、(87.18±0.19)%^(90.8±0.47)%、(2.17±0.57)%^(2.30±0.49)%、(0.15±0.49)%^(0.18±0.37)%、(3.61±0.23)%^(4.99±0.30)%、(38.16±1.86)%^(43.18±2.01)%、(30.10±0.85)%^(34.93±0.98)%之间;OM、CP、EE、Ca、P消化率分别在(70.14±1.37)%^(75.40±2.46)%、(66.75±3.22)%^(67.25±3.04)%、(76.75±1.89)%^(77.25±2.41)%、(47.13±2.13)%^(48.95±3.16)%、(54.60±4.01)%^(56.10±1.48)%之间。研究证明,不同产区杜仲叶营养成分含量和在肉猪体内的表观消化率差异不显著(P>0.05)。
Eucommia Ulmoides Oliv leaf were sampled from 3 main Eucommia Ulmoides Oliv region of Guizhou in July, the primary nutrients such as CP ,EE were analyzed, and also, the digestibility in pig were determiated. The result shown, the DM, CP, EE, CF, OM, Ca, P, Lignin, NDF and ADF content of Eucommia Ulmoides Oliv leaf sampled from different region were ( 33.67 ± 2.08 ) % - ( 44.24 ± 1.04 ) %, ( 12.22 ± 0.65 ) % - ( 13.56 ± 0.74) %, ( 5.47± 1.14) % - (7.91±0.82) %, ( 6.87± 1.48) % - (8.42±0.75) %, (87.18±0.19) % - ( 90.8± 0.47 ) %, ( 2.17±0.57 ) % - ( 2.30±0.49 ) %, (0.15±0.49) % - (0.18±0.37) %, ( 3.61 ±0.23) % - (4.99±0.30) %, ( 38.16± 1.86) % - ( 43.18± 2.01 ) %, ( 30.10±0.85 ) % - ( 34.93±0.98 ) %, respectively. The digestibility for the OM, CP, EE, Ca, and P were ( 70.14 ± 1.37 ) % - ( 75.40 ± 2.46) %, ( 66.75 ± 3.22 ) % - ( 67.25 ± 3.04) %, ( 76.75 ±1.89) % - ( 77.25 ±2.41 ) %, ( 47.13±2.13 ) % - ( 48.95±3.16) %, ( 54.60±4.01 ) % - ( 56.10±1.48) %, respectively. This study demonstrates that no significant differences in nutrients content and digestibility in Eucommia Ulmoides Oliv leaf from different region.
