本试验旨在探讨饲粮中添加云芝菌固态发酵之高粱酒糟(solid fermentation of sorghum distillery residue with Coriolus versicolor,FSDR)对白肉鸡生长性能、肠道发育及营养分消化率之影响.选取200只14日龄且体重相近之白肉鸡,逢机分成5组,喂饲含0％、3％、6％、9％及12％FSDR之饲粮,每组4重复,每重复10只,公母各半,以平地饲养,饲料与水任食,试验为期23天.另选取90只体重相近之白肉鸡,进行消化试验.结果显示,添加FSDR各处理组有显着地较对照组为高之采食量、体增重及试验结束之活体重,饲料转换率则随着FSDR添加量之提高有明显地变差;整段小肠相对重量以添加3％及6％FSDR处理组显着地较对照组为轻;各部位肠道相对长度各组间均差异不显着;十二指肠绒毛发育以添加9％FSDR组较佳;添加12％FSDR组之回肠腺窝深度最深;盲肠绒毛宽度及腺窝深度以对照组最宽及深,绒毛高度/腺窝深度之比,以9％FSDR组最大;添加6至9％FSDR有提高鸡只蛋白质之消化率,其他营养成分各组间均无明显差异.综上所述,添加FSDR有改善肉鸡饲料采食量及体增重,较佳之蛋白质利用率,对肠道发育无不良之影响.

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。
