Four midlactation Holstein cows in a 4 × 4 Latin square design were fed one of four diets that contained 3% added fat (dry matter basis) as 100 0, 67 33, 50 50, or 33 67 tallow:fish oil.
Coconut also has more MCFAs than soybean [ 5], oil palm and safflower, and animal fats such as butter, tallow, fish oil and lard [ 6]-[ 10].
Infusion of linseed oil emulsion decreased plasma TAG concentrations compared with tallow and fish oil treatments, which were similar.
Liver TAG content increased 12.0, 7.8, and 14.1 μg/μg of DNA during the fast for tallow, linseed oil, and fish oil treatments, respectively; linseed oil was different from fish oil and tended to be different from tallow.
Infusion of tallow, linseed oil, or fish oil emulsions increased plasma concentrations of palmitic acid, linolenic acid, and eicosapentaenoic and docosahexaenoic acids, respectively.
The 9 experimental groups were fed 50 g/kg diet of tallow, sunflower oil, or fish oil at three different vitamin E levels (85, 150, and 300 mg all-rac-α-tocopheryl acetate/kg diet).
Treatments included intravenous infusion of tallow, linseed oil, or fish oil emulsions at a rate of 0.54 g of TAG/kg of body weight per day; infusions were concurrent with a 4-d fast.
Male SD rats (7wks) were divided into three groups according to dietary fat sources, beef tallow (BT), corn oil (CO), fish oil (FO) and each group was subdivided into cellulose and pectin groups.
Transgenic mice, expressing porcine PPARγ in skeletal muscle were generated and fed with a high-saturated fat (beef tallow) or high-unsaturated fat (fish oil) diet for 4 months.
In that study, relatively modest changes in fatty acid composition were observed for some phospholipids when comparing fish oil, safflower oil or beef tallow [ 37].
Industries include commercial fishing, meat freezing, dairy and food processing, wool scouring, engineering works, and hosiery, gas, lime, fertilizer, and tallow plants.
