this experiment was conducted to investigate the effects of using three commercial enzymes on performance and carcass quality of broiler chickens fed with wheat-barley-soy based diets. in a completely randomized design 405 of broiler (ross308) in nine treatments, three replicates (with 15 bird in each replicate) were used. the experimental diets included 1) diet based on corn–soybean meal (with...

Vegetable fats and oils are major sources of dietary vitamin E. Consequently the current trend to reduce fat consumption is accompanied by a reduction of the intake of vitamin E.

It is therefore conceivable that a lower dietary fat intake also diminishes the intestinal...

1. In human sympathetic denervation due to primary autonomic failure, food and exercise in combination may produce a cumulative blood pressure lowering effect due to simultaneous splanchnic and skeletal muscle dilatation unopposed by corrective cardiovascular reflexes. We studied 12 patients with autonomic failure during and after 9 min of supine exercise, when fasted and after a liquid meal. S...
