n. [脊椎] 反刍動物(ruminant的複數)
We consider the problem of trace contamination being introduced accidentally during the production of ruminants feedstuffs containing constituents of animal origin.
我們認為,問題的痕量污染正在推行生産過程中不小心的反刍動物飼料含有動物成分的原産地。
Livestock farming drives emissions of the greenhouse gas methane, from the stomachs of ruminants and especially cattle, and of carbon dioxide by increasing deforestation.
畜牧業造成溫室氣體甲烷的排放,甲烷來自反刍動物的胃,特别是牛,畜牧業還通過增加森林砍伐造成更多二氧化碳的排放。
CH_4 emissions from ruminants result in not only a loss of metabolic energy, it is also a greenhouse gas and as such significantly contributes to atmospheric warming.
反刍家畜瘤胃甲烷氣體的排放是一種能量損失,同時對大氣環境具有較強的增溫效應。
Transboundary animal diseases such as Foot-and-Mouth Disease (FMD), screwworm and peste des petits ruminants (PPR) are especially threatening in Iraq and in the region.
諸如口蹄疫(FMD)、螺旋蠅蛆和小反刍動物有害生物(PPR)等跨界動物疾病尤其給伊拉克和該區域帶來威脅。
The nutrition, the absorption approach and mechanism, utilization of small-peptide in ruminants and effects of small-peptide on production performance in cows were reviewed.
本文對小肽的營養,反刍動物對小肽的吸收途徑、吸收機制及其對小肽的利用,小肽對奶牛生産性能的影響進行綜述。
反刍動物(ruminants)是一類具有特殊消化系統的哺乳動物,其核心特征是通過“反刍”過程分解植物纖維。這類動物的胃分為四個腔室(瘤胃、網胃、瓣胃和皺胃),食物在瘤胃中經微生物發酵後會被重新咀嚼并進一步消化。典型的反刍動物包括牛、綿羊、山羊、鹿和長頸鹿等,它們廣泛分布于草原、森林等多種生态系統中。
反刍機制使這類動物能高效利用纖維素為主的植物資源,例如牛的瘤胃微生物可将纖維素轉化為揮發性脂肪酸供能。根據牛津大學動物學系的研究,這種消化方式使反刍動物在食物鍊中占據獨特的生态位,但也因甲烷排放對氣候變化産生影響。世界自然基金會(WWF)的物種保護報告指出,反刍動物的種群動态與植被再生能力存在密切關聯。
"Ruminants"(反刍動物)是指一類具有特殊消化系統的哺乳動物,其特點是通過反刍過程分解植物纖維。以下是詳細解釋:
這類動物在全球農業和生态系統中具有重要地位,其獨特的消化機制是生物適應性進化的典型案例。
