previous work by other investigators indicates a direct relation between the amount of protein in the diet and the level of urea in the blood . however, the present report shows that the type of protein , apart from its level in the ration , also has an effect on blood urea concentrations. when adult male or female rats of two strains were fed a ration in which the only source of protein was wh...

A 56 days grow-out experiment with three protein levels (35, 40 and 45%) and three lipid levels (5, 10 and 15%) was conducted to evaluate the optimum protein to lipid ratio for oriental river prawn (Macrobrachium nipponense). Four hundred and five prawns, with mean (± SD) weight of 1.40 ± 0.04 g were distributed in 27 glass aquaria and were fed four times daily. Results showed tha...

studies on the genes contributing to the seed filling in chickpea and its protein content might be valuable in engineering plants with seeds of a higher nutritional value. a gene of interest is phosphoenolpyruvate carboxykinase (pepck), encoding a protein with a substantial role in the gluconeogenesis pathway. in the present study, the protein content (percentage) was measured in a number of cu...

infectious bursal disease virus (ibdv) is the causative agent of gumboro disease, an infectious disease of global economic importance in poultry. structural protein vp2 of ibdv is the most frequently studied protein due to its significant roles in virus attachment, protective immunity, and serotype specificity. the objective of the present study was to improve the expression of hypervariable re...

an experiment was conducted to evaluate the effect of dietary crude protein and lysine levels on quality and quantity of egg production. fifteen diets consisted of 3 levels of protein (14, 15 and 16%) and 5 levels of lysine (0.71, 0.74, 0.77, 0.80 and 0.83 %) in a 35 factorial arrangement were provided. each diet was randomly fed to 4 replicates of 12 birds, during four periods of 4 weeks (28-...
