在動物飼料中微量元素起著非常重要的作用,是動物必需的營養素,也是機體新陳代謝過程中酶活性中心的重要輔助因子。在現代養殖業和環保方面,飼料中微量元素的品質尤為重要。如果添加不科學,致使配比不合理,少量或過量添加都起不到營養作用,甚至會起到反作用,嚴重者還會使被飼喂動物出現中毒現象。

畜禽需要的微量元素有二十多種,在代謝中起重要作用,是畜禽體內重要結構物質。礦物質雖然不含能量,但是與產生能量的蛋白質、碳水化合物、脂肪等物質的代謝有密切的聯系和巨大的影響,是保證畜禽健康、生長發育過程中所必需的物質。例如鋪、氯是形成胃液和胃酸的原料,并能促進消化酶的活動,使飼料變為可溶解狀態,提高飼料利用率。由于它對消化液的酶有催化作用,增進消化效果,又能改善日糧的適口性,增加畜禽食欲。礦物質微量元素對維持畜禽正常生理機能的作用是很重要的,礦物質的缺乏會引起畜禽多種疾病和癥狀。

劣質飼料或配比不合理的飼料也同樣會造成環境污染、資源浪費。長期使用微量元素含量高的糞便施肥,將導致土壤中微量元素蓄積污染,從而對植物(特別是農作物)產生毒害作用,嚴重影響植物的生長發育,使農作物減產。糞便一旦污染水源,也將產生巨大危害,可使水質惡化,水生物死亡。對于飼料中微量元素的研究也是科研部門比較重視的一塊內容!仲愷農業工程學院就利用凈信全自動樣品快速研磨儀-24L研磨飼料來測量飼料里面的微量元素。

全自動樣品快速研磨儀
上海凈信JXFSTPRP-L®系列組織研磨儀(專利產品,仿冒必究!ZL2019301918692)是一種特殊的、快速的、高效率的、多試管的一致系統。它能將任何來源(包括土壤、植物和動物的組織/器官、細菌、酵母、真菌、孢子、古生物標本等)的原始DNA、RNA和蛋白質進行提取和純化。將樣品和研磨球放入研磨儀內(配置研磨罐或離心管/適配器),在高頻擺動作用下,研磨球在研磨儀內來回高速撞擊及摩擦,在非常短的時間內便可完成樣品的研磨、粉碎、混合及細胞破壁。
上海凈信全自動樣品快速研磨儀針對飼料的研磨方面有其獨到的優勢。具體實驗方案:
1.待研磨樣本若干mg,離心管以及不銹鋼研磨珠若干,清洗并滅菌。
2.待研磨樣本裝入離心管,加入研磨珠,加入試劑
3.將裝有樣品離心管裝入上海凈信全自動樣品快速研磨儀,注意水平配平。
4.鎖緊鎖扣設置參數
5.啟動研磨
待研磨完成后取出樣品如下圖;

結語:用戶傳統的方式是加上試劑用搖床震蕩2小時,然后在靜置8小時,待試劑充分反應后才做下步實驗,而用了上海凈信全自動樣品快速研磨儀后,研磨完成直接離心提取上清液做下步實驗,大大節省了時間。同時對上海凈信全自動樣品快速研磨儀給出非常高的評價!
