探讨分期喂饲灵芝固态发酵物(lingzhi culture,LZC)之饲粮组合对肉鸡生长性能和免疫反应之影响,采用640只白肉鸡逢机分配至2种饲粮于2饲养期所组合而成之4个处理组,包括(A)全期不添加LZC组(对照组);(B)育成期添加LZC组;(C)生长期添加LZC组;及(D)全期添加LZC组.饲粮区分成基础饲粮组和于基础饲粮添加1g/kg LZC组.鸡只平饲饲养,每栏20只.结果发现,育成期添加LZC不影响肉鸡当期之生长性能,但可较对照组提高生长期之体增重和饲料效率以及改善全期之饲料效率(P<0.05).育成期添加LZC降低第21天脾脏细胞增生反应,但提高脾脏CD1+以及盲肠扁桃腺CD3+与CD8+之T淋巴细胞比率,却使脾脏之CD4+下降,而生长期添加LZC可以提高第35天脾脏细胞分泌IFN-γ浓度.综合上述结果,肉鸡饲粮添加LZC处理组合不仅会影响育成期与生长期之免疫反应,且于生长期停止添加后仍然可以改善生长期之体增重和饲料效率,但免疫反应之影响未能延续对免疫反应之影响至生长期结束.

本文分析了蔬菜生产病虫害其发生特点是流行速度快,发生危害重,次要病虫上升为主要病虫,土传病害日趋加重等。目前,蔬菜生产中大量使用化肥、化学农药、生长调节剂等农用化学物质,使农业环境受到不同程度的污染,自然生态系统遭到破坏,土地可持续能力下降,农产品质量安全得不到保证.因此,要实施绿色防控策略,通过调节播期、选用抗病品种、水旱轮作与套作、嫁接、翻耕晒垡、无土栽培、科学肥水运筹、摘除老叶去虫。
