published data on the effects of essential oils (eo) on in vivo nutrient digestibility in sheep are contradictory. in 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete latin square designs. the essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...

to evaluate the effect of different levels of nitrogen fertilizer on growth indices and competitive ability of canola (brassica napus l.) against wild mustard (sinapis arvensis l.), a split plot trial based on a randomized complete block design with three replications, was carried out at agricultural faculty of bu-ali sina university, during 2008-2009. experimental factors were amounts of nitro...

in order to evaluate the effect of using zinc granulated phosphorous biofertilizer on yield and yield components of white bean (phaseolus vulgaris l.), a field experiment based on a randomized complete block design with three replications was performed. experimental treatment were included of using phosphate and triple super phosphorous chemical fertilizer at five levels (without using of chemi...

In this study, the ability of aerobic biogranulation process to remove organic matter, total nitrogen, and phosphorous from wastewater was investigated. The effect matter load on quality produced biogranules settling velocity generated biomass also Four different scenarios were studied in sequential batch bioreactors (SBR) identify best operating conditions. experimental setup consisted four co...

the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...
