Lard is the best choice

Hello Bibiana,

We manufacture many different high fat diets for rodents.  Both Tausif and Kamel are right, and we use lard often in very high fat diets.  Other non-animal based fats such as hydrogenated coconut oil, cocoa butter, or palm oil that could also work fine (cocoa butter is the best as it is very hard at room temperature and we can even pellet diets with cocoa butter at very high fat levels.  Also, I would recommend you consider a matched low fat control diet for your work rather than a grain-based chow so that the differences between the experimental and control diets are just differences in fat and carbohydrate sources.  

If you'd like to discuss this further, please let me know.  I hope this helps and feel free to contact me with any questions.  

Thanks,

Mike
