脂肪35%, 蛋白质12.5%, 碳水化合物16.5%, 酒精36%。
南通特洛菲饲料科技有限公司生产的该模型饲料的代码:TP4036;
【2】低脂型Lieber-DeCarli酒精液体对照饲料:脂肪35%, 蛋白质12.5%, 碳水化合物52.5%。
南通特洛菲饲料科技有限公司生产的该对照饲料的代码:TP4036C;
TP4036是低蛋白质型Lieber-DeCarli酒精液体模型饲料,蛋白质热量为12.5%。
请注意正确理解所谓“低蛋白型”:
所谓低蛋白型,是相对于Lieber-DeCarli标准型(regular type)定义的,而不是针对动物的营养需要量定义的。
Lieber和DeCarli两位研究者在研究酒精性脂肪肝模型时在未成年大鼠中使用,采用的蛋白质热量是18%,这是符合动物对蛋白质的营养需要量的。在研究不同蛋白质的效应时采用了12.5%的蛋白质作为对比,这就称为低脂型。
因此,TP4036是否是低蛋白质型,要看你的研究中采用的是什么情况的动物。如果用于未成年动物、妊娠动物或哺乳期动物,毫无疑问TP4036属于低蛋白型。但如果用于成年,则属于正常脂肪含量,不属于低脂型。
如上所述,这个低蛋白型酒精液体饲料是针对未成年动物、妊娠动物和哺乳期动物而言,当用于成年期时不属于低蛋白型饲料。
1. 用于成年动物进行酒精生理、病理和毒性等相关研究。
2. 用于未成年期、妊娠期和哺乳期蛋白质轻度缺乏情况下酒精的生理、病理和毒性等相关研究。
3. 研究酒精与蛋白质相互作用。
4. 当在成年动物采用其他类型LD酒精液体饲料进行疾病造模时,作为正常蛋白质含量的对照。

请特别注意:
1.购买饲料前:
(1)应当做好动物的准备,注意动物的品种、品系、年龄、性别的选择。
(2)准备好喂养流程的准备。
2. 购买后应当及时向公司索取以下资料:
