Five multiparious Holstein cows, arranged in a 5 5 Latin square design, were fed a control diet (no supplemental fat) and diets containing 5% of the following fat supplements: ̄aked tallow with a low iodine value of 14.4 (FTL), prilled tallow with a low iodine value of 14.5 (PTL), prilled tallow with a medium iodine value of 25.8 (PTM) and fancy bleachable tallow with a high iodine value of 62 ...

This study was performed to examine the effect of different fat sources, lard, sunflower oil (SO), and fish oil (FO) in high-fat and low-fat diet on reactive oxygen species generation by blood phagocytes, glutathione redox status in erythrocytes, and total plasma antioxidant ability in rats. Whole blood chemiluminescence (CL) did not differ between three low-fat fed groups. However, baseline an...

The effect of dietary protein and fat levels on cardiac mitochondrial oxidative phosphorylation was assessed polarographically. Weanling rats were fed on semi-purified diets containing different protein levels (10, 30, 50 and 70%) on a gross energy basis (PGE) for 9, 23 and 58 d. Cardiac mitochondria isolated from rats fed on a 70% PGE diet for 23 d exhibited significantly reduced ADP:oxygen (A...
