Wilhelm, W.W., McMaster, G.S., Rickrnan, R.W. and Klepper, B., 1993. Above-ground vegetative development and growth of winter wheat as influenced by nitrogen and water availability. Ecol. Modelling, 68: 183-203. Assessing the influence of nitrogen and water availability on development and growth of individual organs of winter wheat (Triticum aestivum L.) is critical in evaluating the response o...

= 4.8) (NS) for the diets C and 0, respectively. Lipid and fatty acid intestinal digestibility of oil were calculated by difference to be 50.8% (s = 9.7) and 71.2% (s = 6.2). Energy gain was calculated as the mean of the respiratory quotient (RQ) and carbon-nitrogen (CN) balances. The efficiency (kl) of metabolizable energy (ME) utilization was computed by assuming that the maintenance requirem...

Estimates of nonsymbiotic and associative nitrogen fixation indicate that nitrogen fixation occurs at magnitudes that may be of agronomic significance. Long-term N balances for crop production, although difficult to measure, are necessary for estimating the amounts of N2 fixed. Techniques using N directly to measure nitrogen fixation and problems involved in employing these techniques are discu...

Silage maize cultivation is gaining importance in organic farming, and thus its environmental climate impacts. The effects of digestate fertilization combination with different catch crops tillage intensities are investigated a long-term field experiment southern Germany. tested variants (a) after winter rye, plowed, unfertilized (b) fertilized biogas digestate, (c) legume-rich cover crop mixtu...

Minerals have an important role to play in growth and productive performance of the animals. The present study aimed to analyze the effect of sheanut cake (SNC) and palm press fiber (PPF) inclusion at different levels in the complete diets of buffalo calves on maintaining mineral balance. The experiment was conducted on 18 graded Murrah buffalo calves in 2 x 2 x 2 Latin Square Design (LSD). Thr...

OBJECTIVE To assess whether a late evening meal would improve nitrogen balance in patients with cirrhosis of the liver. DESIGN Randomised crossover study of meal schedules comparing three meals a day with four or six meals a day, the four and six meal schedules both including a late evening meal (2300). SETTING Metabolic ward. PATIENTS Seven men and two women aged 34-66 with cirrhosis of ...

INTRODUCTION Hyperglycemia and protein loss are common in critically ill patients. Insulin can be used to lower blood glucose and inhibit proteolysis. The impact of moderate insulin therapy on protein metabolism in critically ill patients has not been evaluated. We compared urinary nitrogen excretion, nitrogen balance, serum albumin concentrations, prealbumin concentrations, and clinical outcom...

Since Cuthbertson first published his important investigations, the metabolic response to trauma has been the subject of continuous study in many disciplines of medicine (1-8). An impressive body of knowledge has been accumulated with respect to changes in plasma electrolyte concentrations, urinary electrolyte excretion, body composition, and adrenocortical activity. There is general agreement ...
