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...

An experiment was carried out to determine the ileal digestibility values of NDF, CP, and AA associated with NDF in different samples of wheat shorts consisting of different proportions of wheat bran, shorts, and flour, hereafter referred to as wheat fractions. Six barrows (average initial BW 37.2 kg, and fitted with a simple T-cannula at the distal ileum) were fed one of six experimental diets...

BACKGROUND Mannosylerythritol lipids (MEL) are glycolipids with unique biosurfactant properties and are produced by Pseudozyma spp. from different substrates, preferably vegetable oils, but also sugars, glycerol or hydrocarbons. However, solvent intensive downstream processing and the relatively high prices of raw materials currently used for MEL production are drawbacks in its sustainable comm...

the sunn pest, eurygaster integriceps puton, is a serious pest of wheat in coraim region of ardabil province. in this study, the egg parasitoids of sunn pest was collected and identified in this region during 2007 and 2008. also, the percentage of egg parasitism was determined in 14 different defined areas in this region. the areas 1-3 were selected in irrigated wheat fields in the presence of ...

Two experiments were conducted, each with 24 White Pekin ducks, to determine the AME and TME content of five feedstuffs for ducks. In each experiment, fasting losses were obtained from six ducks and six ducks were used for each feedstuff. Each experiment lasted 102 h with an initial 48-h period and a 54-h excreta collection period. During the first 48-h period, all birds were tube-fed dextrose ...

this experiment was conducted to investigate the effect of mint powder added to diet with different levels of wheat on performance, microbial population and carcass characteristics of broiler chickens. a total of 384 ross male broiler chickens were used in a completely randomized design in a 4×2 factorial arrangement with 4 replicates (floor pens) and 12 birds each. birds were fed diets contain...

this study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. about 4.5 kg urea and 1.5 kg salt were dissolved in 40 l water and mixed with 30 l of whey. the solution was spread over 100 kg chopped wheat straw. thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...

This study was designed to explore the nutritional relationship between Gregarina confusa (Apicomplexa: Eugregarinida) parasites and its coleopteran host, Tribolium destructor, by measuring the cytoplasmic density of gregarines in continuously fed larvae, starved larvae, and larvae refed after starvation. Cultures were maintained in a standard media (whole wheat flour:commercial wheat germ:yeas...

cyclical, and is historically dependent on factors affecting world supply and demand for wheat as a human foodstuff. Wheat generally becomes economically feasible to feed when the price per bushel is 108–115% that of corn, as a result of higher bushel weight and protein concentration. This generalized value is somewhat of a “moving target” as numerous factors affect the ability to utilize wheat...

The present study in a two-year experiment investigated the influence of drought and sowing time on protein composition, antinutrients, and mineral contents of wheat whole meal of two genotypes differing in their water requirements. Different thermal conditions prevailing during the grain filling period under different sowing time generated a large effect on the amount of total soluble proteins...
