碳水化合物调节Envigo
harlan teklad官网代理商 动物饲料 碳水化合物调节 TD.89247 60%果糖饮食
公式示例：
- TD.89247 60%果糖饮食
- TD.86489调整蔗糖/玉米淀粉的饮食
- TD.96348日粮(20%乳糖，2%钙，1.25%P)
- TD.9809070%碳水化合物饮食
- TD.96355生酮饮食(几乎没有碳水化合物)
碳水化合物往往占大多数(按体重和%千卡)的习惯研究饮食，除了高脂肪饮食。常用的碳水化合物来源包括蔗糖、玉米淀粉和麦芽糊精。其他来源包括果糖、葡萄糖、糊精和乳糖。麦芽糊精是从玉米淀粉中得到的酶解物，它含有较短的葡萄糖聚合物，有助于高脂饲料的颗粒化和玉米淀粉超过蔗糖的饮食。
蔗糖是大多数配方的一部分，通常占饮食的10%或更多。这可能会增加饮食的适口性。饮食中的碳水化合物可以被操纵，尽管有些混合物可能不是颗粒。也有很少碳水化合物的饮食，因此含有大量的脂肪和/或蛋白质。
纤维素(纤维)是许多配方的一部分，虽然不是啮齿动物所必需的，但被认为是有益的。它也可以用来制作不同的黄金分割配方等热量。
Carbohydrate adjusted | Envigo
Formula examples:
- TD.89247 60% Fructose diet
- TD.86489 Diet with adjusted sucrose/cornstarch
- TD.96348 Diet (20% lactose, 2% Ca, 1.25% P)
- TD.98090 70% Carbohydrate diet
- TD.96355 Ketogenic diet (almost no carbohydrate)
Carbohydrates often make up the majority (by weight and % kcal) of custom research diets, with the exception of higher fat diets. Commonly used carbohydrate sources include sucrose, cornstarch and maltodextrin. Other sources include fructose, dextrose (glucose), dextrin, and lactose. Maltodextrin is enzymatically derived from cornstarch to have shorter glucose polymers and is helpful in pelleting high fat diets and in diets where cornstarch exceeds sucrose.
Sucrose is a part of most formulas, often making up 10% of the diet or more. This likely adds to the palatability of the diet. The carbohydrate profile of a diet can be manipulated, although some mixtures may not pellet. There are also diets with very little carbohydrate, thus containing high amounts of fat and/or protein.
Cellulose (fiber) is part of many formulas and while not required by rodents, is considered beneficial. It can also be used to make formulas with differing macronutrient profiles isocaloric.
