【摘要】 对４月龄感染了马立克氏病的２月龄～６月龄乌黑鸡群血清蛋白及血清酶的研究结果表明：２月龄～３月龄健康乌黑鸡群血清蛋白升高极显著（Ｐ＜０．０１），血清ＡＬＰ活性下降显著（Ｐ＜０．０５），ＡＭＳ活性下降不明显（Ｐ＞０．０５），ＣＨＥ活性升高不明显（Ｐ＞０．０５）。 ４月龄感染 ＭＤ后，血清蛋白显著降低（Ｐ＜０．０５）。而后，球蛋白逐月回升，变化均不明显（Ｐ＞０．０５），白蛋白在５月龄再次极显著降低（Ｐ＜０．０１），６月龄迅速升高（Ｐ＜０．０１），总蛋白在５月龄下降不明显（Ｐ＞０．０５），６月龄明显升高（Ｐ＜０．０１）。４月龄血清ＡＮＥ活性升高极明显（Ｐ＜０．０１），ＣＨＥ与 ＡＬＰ活性下降极明显（Ｐ＜ ０． ０１）， ５月龄三种酶活性均下降十分明显（Ｐ＜ ０． ０１）， ６月龄均上升，其中 ＡＭＳ不明显（Ｐ＞０．０５），ＣＨＥ与ＡＬＰ极显著（Ｐ＜０．０１）。更多还原

【Abstract】 Studies on serum proteins and enzymes of from ho to six-month-old Black chickens infected with MD at four-month-old demonstrated that: At two to three-month-old, serum protein content fm healthy black chickens increased significantly(p< 0. 01), and ALP activity decreased significantly(p< 0. 05), but activities of AMS and CHE decreased and increased insignificantly respectively(P>0. 05) .At four-month-old, birds were infected with MD naturally, serum protein contents decreased significantly (P < 0. 05 ). Sine e then, globulin content increased insignificantly month after month. Albumin content decreased significantly(p<0. 01) again at five-month-old and increased significantiy at six~month-old(p<0.01). Total protein content decreased insignificantly at five-month-old and increased significantly at sin. In addition, at four-month-old, AMS activity increased significantly(p< 0. 01), but activities of CHE and ALP ed decreased significantly(p<0. 01) .At five, activities of all the three enzymes decreased significantly(p < 0. 01) .At the age of six-month-old, their activities all increased, but activity of AMS was not significant and others were significant(p< 0. 01).更多还原
