harlan teklad官網 動物飼料 脂肪/脂調節(jié) TD.96355生酮飲食
在飲食中調節(jié)脂肪的水平和來源是有很多可能性的。如果你的主要興趣是引發(fā)動脈粥樣硬化或肥胖癥,你可以在我們的特克樂上找到更多的信息。動脈粥樣硬化和飲食誘導肥胖(Dio)飲食頁。根據你的研究目標和所需要的脂肪補充水平,脂肪可以添加到一個標準的天然成分飲食或凈化飲食。
純化的成分被提煉到化學簡單的程度,并允許極端的脂肪水平,例如沒有脂肪飲食。TD.03314或者是高脂肪的生酮飲食TD.96355。除非對纖維水平做出調整,否則高脂肪水平的飲食將有更大的熱量密度,因為脂肪含有9千卡/克,而碳水化合物或蛋白質為4千卡/克。動物善于調節(jié)熱量的攝入,因此通常調整其他營養(yǎng)素(維生素、礦物質、蛋白質)相對能量含量,以說明飼料攝入量的差異。
特殊脂肪可以用于這種必需脂肪酸缺乏的飲食中。TD.84224或從亞麻籽或魚油中提供較高水平的omega-3多不飽和脂肪。通常,玉米或大豆油等植物來源的1-2%的脂肪會提供足夠的必需脂肪酸。額外的脂肪提供能量,并可影響適口性,因為影響口味和飲食結構。
混合脂肪可以用來模仿西方或地中海的飲食脂肪酸譜。聯系我們獲得一張比較幾種脂肪來源(固體脂肪、油脂)脂肪酸組成的表格。
我們還經常與客戶提供的油和純化脂肪酸,如DHA和EPA。如果你喜歡在你的實驗室里混合脂肪源,問一問基本的混合?;A混合是以粉末形式提供的,并且經常允許您使用一種飲食組合來創(chuàng)建幾種不同的飲食。
如果脂肪穩(wěn)定性是一個問題,聯系營養(yǎng)學家討論飲食干燥,真空包裝,合成抗氧化劑補充選擇。

Fat/lipid adjusted | Envigo
There are numerous possibilities in adjusting both the level and source of fat in a diet. If your primary interest is inducing atherosclerosis or obesity, additional information can be found on our Teklad?atherogenic?and?diet induced obesity?(DIO) diet pages. Depending on your research goals and level of desired fat supplementation, fats can be added to a standard natural ingredient diet or a purified diet.
Purified ingredients are refined to the point of chemical simplicity and allow for extreme fat levels such as no fat diet?TD.03314?or very high fat ketogenic diet?TD.96355. Unless adjustments are made to the level of fiber, diets with high fat levels will have a greater caloric density since fat contains 9 kcal/g versus 4 kcal/g for carbohydrate or protein. Animals are good at regulating caloric intake, therefore it is common to adjust other nutrients (vitamins, minerals, protein) relative to energy content to account for differences in feed intake.
Specific fats can be utilized as in this essential fatty acid deficient diet?TD.84224?or to provide high levels of omega-3 polyunsaturated fat from flaxseed or fish oil. Normally, 1-2% fat from plant sources like corn or soybean oil will supply sufficient levels of essential fatty acids. Additional fat provides energy and can influence palatability due to effects on taste and texture of the diet.
Mixtures of fats can be used to mimic a Western or Mediterranean diet fatty acid profile. Contact us for a table comparing the fatty acid composition of several stocked fat sources (solid fats, oils).
We also commonly work with customer supplied oils and purified fatty acids such as DHA and EPA. If you prefer to mix fat sources in your lab, ask about a basal mix. Basal mixes are supplied in powder form and often allow you to use one diet mix for creating several different diets.
If fat stability is a concern, contact a nutritionist to discuss options for diet drying, vacuum packaging, and synthetic antioxidant supplementation.
