this experiment was carried out to evaluate the effect of different levels guar meal and β-mannanase on broilers male chicken. in this experiment , four hundred ross day old broiler chicks were randomly assigned to a 4×2 factorial design to feed broiler chickens diets containing guar meal at 4 level of guar meal (0, 3, 6 and 9%) with five replications of each treatment with or without β-mannana...

effect of intermittent mash-pellet feeding programs on broilers performance, ascites susceptibility and economic yield was studied using 480 broilers in six treatments and five replicates of 16 chicks per pen were used in a completely randomized design. treatments including: 1. mash feed, 2. heated-mash feed, 3. mash feed in starter and grower and pellet feed in finisher, 4. mash feed in starte...

an experiment was conducted to investigate the effects of different levels of rapeseed meal and diet formulation based on total and digestible amino acid (aa) using 192 day old ross 308 male broiler chicks. experiment was carried out using a complete block design with 4*2 factorial arrangements. the factors included different levels of rapeseed meal (0, 10, 20 and 30%) and two method of aa form...

Risers are considered vital parts on fluidized catalytic cracking (FCC) conversion units. It is inside the riser that the heavy hydrocarbon molecules are cracked into petroleum fractions such as gasoline and liquefied petroleum gas (LPG). A simplified kinetic flow model in combination with the Tank-In-Series model was used to predict the conversion response of an FCC riser to changes in feed te...

the role of nickel as catalyst on the conversion of methane and ethylene in a gas phase flow reactor in the absence of oxygen is studied. in this study, nickel in its different forms is used as catalyst. the role of pressure, flow rate, and temperature on the conversion of feed gases is investigated. the experiments have been carried out in the presence and absence of the catalysts to measure t...

the potential of marine actinobacteria particularly streptomyces as a single cell protein (scp) feed for the growth of ornamental fish, xiphophorus helleri has been investigated. the streptomyces strains used as scp were isolated from the marine sponges, namely callyspongia diffusa , mycale mytilorum , tedania anhelans and dysidea fragilis . six scp feeds were prepared and their effects were co...
