摘要
选取3月龄的健康试验鹅48只，随机分为8组，进行消化代谢试验。各试验组日粮分别添加6．15％，10．10％，13．60％，17．05％，19．80％，22．50％，24．30％，28．60％的苜蓿粉，结果表明：在代谢能（ME）和粗蛋白（cP）等摄入量一致的条件下，苜蓿粉含量为6．15％-28．6％（CF含量为5．41％-12．05％）时，粗纤维（CF）的消化率为17．15％^，25．35％，中性洗涤纤维（NDF）21．04％-33．80％，酸性洗涤纤维（ADF）19．10％-28．08％；表观氮沉积（ANR）组间差异不显著（P〉0．05）；粪中氨态氮（NH4^＋-N）浓度显著下降（P〈0．05）；各种氨基酸（AA）消化率较高（75．62％～93．31％）；碱性磷酸酶（AKP）活性与CF、NDF和ADF消化率呈显著负相关（P〈0．05）；酸性磷酸酶（ACP）、谷草转氨酶（GOT）、谷丙转氨酶（GPT）、胆碱酯酶（CHE）、肌酸激酶（CK）、脂肪激酶（LPS）和乳酸脱氢酶（LDH）的活性与营养物的消化率呈弱相关（P〉0．05）。
Forty-eight healthy three-month-old geese were divided into eight groups and were fed with isoenergetic and isonitrogenous diets which contained different proportions of alfalfa green hay powder （6.15 %, 10.10%, 13.60%, 17.05%, 19.80%, 22.50%, 24.30%, 28.60% respectively）. The resuits indicated that： CF digestibility changed in the range of 17.15% -25.35%, NDF in 21.04% 33.80% and ADF in 19.10% - 28.08%; There were no significant difference in apparent nitrogen retention（ANR） between the eight groups （P 〉 0.05）; NH4^＋ - N content in feces dropped with the increase of alfalfa powder proportion; AA digestibility reached a high level （75.62% - 93.31 % ） ;AKP activation in plasma ascended significantly （ P 〈 0. 05） and it had significant negative correlation with CF, NDF and ADF digestibility （ P 〈 0. 05） ; ACP, GOT, GPT, CHE, CK, LPS and LDH activities had little correlation with fiber digestibility and Met, Cys digestibility （ P 〉 0. 05）.
