The effects of urea and rumen-degradable protein (RDP) on microbial growth, digestibility, and fermentation were examined using dual-flow continuous culture. The experimental design was a 4 x 4 Latin square with a 2 x 2 factorial arrangement of treatments. Factors were urea infusion (0.4 g/L of artificial saliva) and RDP concentration, and the treatments were as follows: 1) low RDP (8% of dieta...
use poor quality resources of water and soil for food production in developing countries must be considered. therefore, three experiments were conduct in complete randomize design with four replications, to study effects of gradually application of different salinity levels (0, 10, 20, 30, 40, 50 and 60 ds.m-1) at different growth stages (planting and early seedling) and gradually application s...
In this research, the effect of different parameters of coal composition (coal chemical properties) were studied, to estimate the coal HGI values index. To estimate the HGI values artificial neural networks (ANNs) and linear multivariable regression methods were used for 400 data. In this work, ten input parameters, such as moisture, volatile matter (dry), fixed carbon (dry), ash (dry), total s...
a simple mechanistic model was constructed to evaluate potential dry matter of pearl millet. all needed parameters were calculated based on many field and laboratory experiments and actual data obtained from 86 fields of millet located at different regions of khorasan's provinces. the major simulated processes were crop phenology (as a function of temperature and photoperiod function curve...
in order to evaluate the effect of nitrogen rates and green manure crops on dry matter mobilization and mobilization efficiency indices of wheat (triticum aestivum l.) a field experiment was conducted in agricultural faculty of shahid chamran university, ahvaz during growing season of 2010-2011. the experimental design was split-plot based on randomized complete block with three replications. m...
calendula (calendula officinalis) is relatively cold tolerant plant, but in some years plant seriously injured due to harsh winter. in order to evaluate freezing tolerance of calendula an experiment was carried out at college of agriculture, ferdowsi university of mashhadin a factorial-completely randomized design with three replications and plants of two sowing dates (summer and autumn) were e...
in order to evaluate different sources and rates of nitrogen on dry matter yield, concentration and uptake of primary macronutrients (nitrogen, phosphorous and potassium) in forage sorghum (hybrid of speedfeed), three levels of nitrogen (80, 160 and 240 kg n ha-1) from three n sources (urea fertilizer, cattle manure and equal combination of urea fertilizer + cattle manure) and the control (no f...
Effect of Adding Whey and L. Buchneri to Alfalfa Silage on In Vitro Gas Production and Degradability
Ensiling alfalfa is difficult due to some restrictions such as low water soluble carbohydrate concentration and high buffering capacity. This study was conducted to document the effects of supplementation of alfalfa silage with fresh whey and bacterial additive on gas production, dry matter, organic matter and crude protein degradabilities by in vitro method. Experimental treatments included th...
