in order to evaluate the effects of nitrogen fertilizer on yield, yield components and dry matter remobilization of different rice genotypes, a field experiment was carried out at the farm of ramin agricultural and natural resources university (ahwaz/iran) during 2007. experiment was arranged in a split plot based on randomized complete block design with three replications. four nitrogen fertil...

For the first time, highly elevated levels of mercury (Hg) have been documented for several species of the edible Fungi genus Boletus growing in latosols, lateritic red earths, and red and yellow earths from the Yunnan province of China. Analysis of Hg concentrations in the genus suggests that geogenic Hg is the dominant source of Hg in the fungi, whereas anthropogenic sources accumulate largel...

This study was conducted to investigate the effect of biological treatment withPleurotus floridafungi on chemical composition and rumen dry matter (DM) and organic matter (OM) degradability of wheat and barley straw. Wheat and barley straw were collected from Golestan province of Iran and after pasteurization mixed with fungi spawn (than 5% by weight). After 21 days samples were dried in oven (...

Two digestion experiments were conducted to determine the effect of various levels of potato processing residue in feedlot diets on digestion of dry matter, gross energy, crude protein and starch. In Exp. 1, 10 Hereford steers (average weight 360 kg) were randomly allotted to one of five diets in which (1) 0, (2) 15, (3) 30, (4) 45 or (5) 60% of diet dry matter was provided by potato processing...

Near-infrared transmittance (NIT) spectroscopy was used to predict the percentage in weight of the fat, dry matter, protein and fat/dry matter contents in Zamorano cheeses, protected with a Designation of Origin by the European Union. A total of 42 cheeses submitted to official control were analysed by reference methods. Samples were scanned (850-1050 nm) and predictive equations were developed...

Individual growth and feed intake of 36 Angus, 27 Polled Hereford and 30 Holstein steers were determined from 365 to 560 kg live weight. One-half of the cattle in each breed were fed a diet based on high-moisture ear corn and the other one-half were fed a diet based on corn silage. Within each breed X diet group, half of the cattle were implanted with zeranol. Cattle fed the high-moisture ear c...

The nutritive values of non- processed and processed grape pomace with Neurospora sitophila were evaluated. The chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. An in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (DOMD) to estimate ...

%Moisture & %Dry Matter Labs determine the %moisture content of submitted samples by drying the sample, and calculate the %dry matter; (DM% = 100 %moisture). Most lab analysis reports list test values on both the basis of %Dry Matter, and “As Fed”, “As Is” or “As Received.” Forage nutritive values should be evaluated, and rations balanced on a dry matter basis. Once the forage needs have been d...
