1. The efficacy of oral vitamin E supplementation in preventing the early anaemia of the premature infant was assessed in a 10-week double-blind trial. Forty-two babies received either a placebo or 5 or 15 mg supplementary vitamin E/d with oral feeding. No infant received less than the recommended vitamin E:polyunsaturated fatty acid (E:PUFA) value of 0.6. No iron supplement was given. 2. Weekl...
1. The supplementation of diets rich in soluble polysaccharides with microbial cellulases and hemicellulases decreases digesta viscosity and promotes broiler performance. 2. In contrast, recent experiments suggest that polysaccharidases are ineffective for improving the nutritive value of pasture biomass used by free-range broilers. However, the feasibility of using cellulases and hemicellulase...

By targeting specific anti-nutrients in certain feed ingredients, feed enzymes allow especially pig...
Feeds is major of current values in intensive fish and other aquatic animal culture (30-60% approximately). Therefore, aquaculture scientists have been attempted to find feed costs decreasing approaches. Earth worm (Eisenia fetida) is one of the most important commercial species. It can use in fish farming especially rainbow trout farms. Therefore, the study was conducted to investigate E.fet...
The two open-ended frontiers in radio astronomy instrumentation are collecting area and field of view. Greater collecting area translates directly into greater sensitivity while increased field of view increases observing efficiency and makes feasible new areas of science, such as searches for transient radio sources, rare types of pulsars, and surveys of large portions of our Galaxy and of the...
