| 摘 要： | 试验用一日龄Aiboi Acies雏鸡6O只分三组,分别喂给低锌自然饲粮(含锌25.75ppm);低锌高钙饲粮(含锌26.75ppm 钙1.5％);补锌饲粮(含锌25.75ppm 锌50ppm)。缺锌雏鸡生长缓慢,并可发生死亡,最特征性病变是羽囊角化亢进、发炎、变性、坏死和机化,故羽毛发育不良,寡毛,羽枝脱落;其次是淋巴组织萎缩。 缺锌病雏血清碱性磷酸酶活性下降和肝锌含量降低。

| Abstract: | sixty-day-old Aiboi Acies chicks were divided into three groups, by feeding zinc-deficient diet ( 25.75ppm zinc ) , zinc-deficient diet containing high calcium(26.75ppm zinc and 2.5% calcium) ,zine deficient diet zinc ( 50ppm zinc) , for periods of 6 weeks.The zinc deficiency groups appeared slow growth and characteristic poor feather growth. Microscopical examination showed the hyperkeratinization, inflammation, coagulation necrosis and organization of the feather follicle. Lymphocytes decreased in Lymphatic organs. The relationship of pathological lesions and clinical signs, pathomorphological character , and Pathogenesis were discussed in this paper. |
