6禽流感及其它接触性传染病对家禽福利的影响显示文摘现代规模化家禽生产结构,使得传染性病毒病、细菌病及寄生虫病能够在很短的时间内感染大量禽只。最近几年,高致病性禽流感(HPAI)已经在世界多个地区相继暴发。禽流感、新城疫以及其它严重疾病的暴发,不但造成了严重的经济损失,同时也带来了大量的家禽福利问题。本文将重点以禽流感为例,阐述相关传染性疾病对家禽福利造成的影响。C.Berg 朱云芬(译) 2010中国家禽2010,32,4:0
7Survivorship, attained diameter, height and volume of three Paulownia species after 9 years in the southern Appalachians, USA显示文摘Little is known of the tree and stand dynamics of varied species of planted Paulownia left unmanaged until harvest in the southeastern United States.We sought to remedy this lack of information needed by land managers to make informed decisions by investigating diff erences in survivorship,attained diameter breast height(DBH),diameter at ground level,total height,tree volume and standlevel volume yields of planted P.elongata,P.fortunei,and P.tomentosa in the cool-moist environment of the southern Appalachian Mountains.After 9 years,combined-species survivorship was only 27.3%.Low survivorship was likely related to several inclement weather events.P.fortunei was signifi cantly smaller in DBH and total height.Three combined-species stem(bole)volume models were developed as functions of(1)DBH squared,(2)the product DBH squared and total height,and(3)the product diameter ground line squared and total height.Mean total volume production of unmanaged stands was greatest for P.elongata and P.fortunei 4 years after planting;by the 9th year,total volume of P.elongata was greater than the other two species.Results of our study provide managers information on productivity of three species of Paulownia that can be used for estimating plantation yields.Erik C.Berg Stanley J.Zarnoch W.Henry McNab 2020Journal of Forestry Research2020,31,6:0
