Key result
Added animal fat diets caused significant (P<0.05) changes in fatty acid levels within lipoprotein and whole serum fractions, but did not significantly influence lipoprotein fraction concentrations.
Population
12 half-sib Hereford steers
Comparison
Rations containing 5%, 10%, and 15% added animal… vs Ration containing 0% added animal fat

In a bovine model, increasing dietary animal fat altered the fatty acid composition of serum lipoproteins without significantly changing their overall concentrations.
Dryden et al. (1971) reported an RCT. Added animal fat diets vs. 0% added animal fat was evaluated on Lipoprotein fraction concentrations and fatty acid profiles (p=<.05). Added animal fat diets caused significant (P<0.05) changes in fatty acid levels within lipoprotein and whole serum fractions, but did not significantly influence lipoprotein fraction concentrations.
