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...

The nutritive value of Pleurotus ostreatus (Jacq. ex Fr.) Kumm., Pleurotus sajor-caju (Fr.) Singer, and Agaricus bisporus (Large) Sign. was determined. Dry matter, moisture, crude ash, protein, fat, cellulose, organic matter, and nitrogen-free extract were 89.7%-90.3%, 9.7%-10.3%, 6.0%-13.7%, 27.8%-41.6%, 0.5%-1.3%, 10.0%-16.2%, 76.0%-84.0%, and 26.7%-36.8% of dry weight, respectively. Mineral ...

Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...

Seeds of 200 accessions of alfalfa (Medicago sativa L.) were provided from Iraniannatural resource gene bank and were sown as drilled plot using alpha designs/unreplicatedwith 2 repeated entries within all of 10 blocks under dry land farming system in agriculturalresearch center of Hamadan, Iran during 2009 to 2010. The data were collected and analyzedfor plant height, stem number, leaf stem ra...

in order to investigate of different salinity stress and plant densities effects on quantitative and qualitative forage and grain yields of kochia a randomized complete block design in factorial arrangement with three replications was used. a field study was conducted in 2011 cropping season in agriculture experiment satiation, college of agriculture, islamic azad university, arak branch treatm...

Thirty five growing male goats (6.98±0.86 kg BW) were divided into five equal groups with seven animals in each group. The five dietary treatments were consisted of varying proportions of Moringa foliage (Moringa oleifera) and napier grass (Pennisetum purpurium); T1 (100% Moringa foliage); T2 (75% Moringa foliage+25% napier grass); T3 (50% Moringa foliage+50% napier grass); T4 (25% Moringa foli...

this study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (pbpm) from two slaughterhouses in iran. samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. the amounts of calcium, phosphorus, sodium, potassium, magnesium, iron, manganese, copper and zinc were determined. the apparent metabolizable energy (...

The aim of this study was to evaluate the importance of fruits and seeds as food items in the natural diet of the tambaqui (Colossoma macropomum). During one year, tambaqui's stomach contents were collected, and their nutritional and energetic values were determined. During the flooding period, and while the river water was rising, which coincided with a high availability of fruits and seeds, t...
