Supply chain traceability is key to reduce food safety risks,since it allows problems to be traced to their sources. Moreover,it allows regulatory agencies to understand where risk is introduced into the supply chain,and offers a major disincentive for up
Leptin receptor(LEPR)plays a vital role in obesity in humans and animals.The objective of this study is to assess LEPR functional variants for chicken adipose deposition by integration of association and in-silico analysis using a unique chicken populatio
为研究潘阳湖刀鲚资源状况,2019-2020年在鄱阳湖开展鱼类资源调查工作,采集到大量鲚属(Coilia)鱼类,对这些样本进行了形态学和分子生物学的鉴定.随机测量112尾样本的上颌骨长
Due to global climate change,Korea is facing severe droughts that affect the planting and early vegetative periods of upland crops.Soybean and adzuki bean are important legume crops in Korea,so it is critical to understand their adaptations to water stres
鱼类是湖泊食物网中的重要消费者,占据食物网多个营养级.通过食物网营养级联效应,鱼类对湖泊生物群落结构和水环境可产生重要影响.本研究以长江中下游浅水湖泊——傀儡湖为例
Nitrogen fertilizer application is an important measure to obtain high and stable corn yield, and the moisture content of corn grains is an important factor aff
家禽业的主要目标是增加胴体产量和降低胴体脂肪。由于禽肉消费的增加,使快速生长型肉鸡在育种过程中向降低饲料转化率发展,同时为了满足消费者的需求,重点考虑了一些经济性状如体重增加、饲料效率和胸肌产量,但现代商业鸡在腹部出现过多的脂肪沉积,日粮组成和饲喂策略可能为降低现代家禽品系体脂肪沉积提供实用和有效的解决方案。文章旨在阐明影响脂质代谢相关酶的作用机理及饲养策略对脂肪沉积的影响,为促进家禽瘦肉和肉品质提供理论依据。
利用Ecopath with Ecosim(EWE)模拟生态系统能量通道模型,比较分析了鲥鯸淀生态修复区和对照区的生态系统结构、食物网变化和能量流动特征.结果表明,生态修复区同种鱼类营养
鳜(Siniperca chuatsi Basilewsky)是淡水生态系统中的顶级捕食者,也是我国传统的渔业对象.多年来由于人类活动的过度干扰导致现阶段湖泊、水库等大水面鳜自然资源衰退严重.
Waterlogging is becoming an obvious constraint on food production due to the frequent occurrence of extremely high-level rainfall events.Leaf water content(LWC)is an important waterlogging indicator,and hyperspectral remote sensing provides a non-destruct
