苜蓿结构日粮对鹅血浆酶活性的影响

本试验以含8种等能量等蛋白的不同苜蓿粉配比的结构日粮饲喂3月龄鹅。测定鹅血浆中碱性磷酸酶（AKP）、酸性磷酸酶（ACP）、胆碱酯酶（CHE）、肌酸激酶（CK）、脂肪激酶（LPS）、谷草转氨酶（GOT）、谷丙转氨酶（GET）和乳酸脱氢酶（LDH）的活性，并将其与纤维消化率、钙（Ca）表观消化率、蛋氨酸（Met）和胱氨酸（Cys）的表观消化率进行相关性分析比较。试验结果表明，随着苜蓿粉比例的增加，鹅血浆中的AKP活性呈显著性升高的趋势（P=0．005），并与粗纤维（CF）、中性洗涤纤维（NDF）和酸性洗涤纤维（ADF）消化率呈显著负相关忙0．02，0．04，0．03），与Ca消化率呈极显著正相关（P=0．007）；其他7种酶的活性与CF，NDF，ADF消化率．Ca，Met，Cys表观消化率呈弱相关。

Affection of Distinct Proportion of Alfalfa Meal in Diets to Activities of Plasma Enzymes in Geese

The activities and correlation of plasma AKP,ACP,CHE,CK,LPS,GOT,GPT,LDH were determined in 3-month-old high grow rate line geese by means of feeding the distinct proportion alfalfa meal.The result indicated as the proportion of the alfalfa meal,the activity of AKP presented increasing significantly(P<0.01),the activity of AKP in Wulong geese was presented significantly negative correlation with the weight degradation,the digestion ration of crude fiber(CF),neutral detergeng fiber(NDF)and acid detergent fiber(ADF)(P<0.05) the significant positive correlation with the digestion ration of Calcium(P<0.05);the activities of other seven enzymes were presented slight correlation with the digestion ration of CF,NDF,ADF,Ca,Met and Cys(P>0.05).
