High Fat Feeding Induces Hepatic Fatty Acid Elongation in Mice

BACKGROUND High-fat diets promote hepatic lipid accumulation. Paradoxically, these diets also induce lipogenic gene expression in rodent liver. Whether high expression of these genes actually results in an increased flux through the de novo lipogenic pathway in vivo has not been demonstrated. METHODOLOGY/PRINCIPAL FINDINGS To interrogate this apparent paradox, we have quantified de novo lipog...

Conjugated linoleic acid content of beef differs by feeding regime and muscle.

The project objective was to determine the CLA content of three muscles (Longissimus lumborum, LD; Semimembranosus, SM; Triceps brachii, TB), in both raw and cooked states, in cattle finished on pasture or with grain supplements. Cattle were randomly assigned to one of four finishing regimens; pasture (n=11), pasture with grain supplement (n=11), pasture with grain supplement containing soyoil ...

Sources of Variation in Subcutaneous Fat Colour of Beef Carcasses

Yellow fat in beef carcasses incurs price penalties in many domestic and export markets. Sources of variation in subcutaneous fat colour of beef carcasses was investigated by objective measurements on 622 carcasses of various classes of cattle. Fat colour was subjectively assessed using a six point photographic colour chart . The majority of carcasses sampled (80.6%) had creamy-white to cream f...

The effects of feeding various forages on fatty acid composition of bovine milk fat: A review

The nutritional image of bovine milk fat has suffered for years because of the association of saturated fatty acids and coronary heart disease. Thus the alteration of fatty acid composition has been a long-term strategy. Forages, even though containing a relatively low level of lipids, are the cheapest and often the major source of beneficial unsaturated fatty acids in ruminant diets. Recent pr...
