Dietary effects on fat deposition and fatty acid profiles in muscle and fat depots of Friesian bull calves.

Dietary effects on fat deposition, cholesterol level, and fatty acid profiles of muscle and fat depots in Friesian bull calves were evaluated in two trials. In Trial 1 (eight pens of seven Friesian bull calves), three levels of ME (10.4, 10.

Modulation of the mitotic action of ethylene dibromide.

Refeeding rats treated with a single high dose of ethylene dibromide (1,2-dibromoethane, EDB) induced liver DNA synthesis. The peak of DNA synthesis, as measured by [methyl-3H]thymidine incorporation was attained after 24 h in refed rats and at 48 h in fasted ones. Fasting enhances the EDB action leading to liver cell necrosis, as shown by elevation of serum enzymes' activities, glutamic pyruvic transaminase (GPT) and sorbital dehydrogenase (SDH).

Effects of isocaloric supplements of glucose or soyabean oil on lipids in tissues and plasma lipoproteins of starved and overfed chicks.

Chicks were overfed a basic diet supplemented isocalorically by soyabean oil or glucose 1, 2 and 10 days after 1 day of starvation. Carcass lipids resumed the prestarvation level 1 and 2 days after overfeeding with oil or glucose, respectively. After 10 days, an equal amount of lipid, mainly triglycerides, accumulated in the carcasses of both supplement groups.
