this experiment aimed to investigate the effect of (zero, 20, 40 and 60 mg/kg atriplex forage) malva sylvestris on digestibility and microbial fermentation of atriplex in one-humped camel. fermentation parameters by gas production technique and in vitro digestibility by two-stage digestion were measured by two years old female fistulated camels. addition 40 and 60 mg/kg malva sylvestris increas...

Some often cited reasons why both grain and forage prices are and will continue to be high include utilizing corn for ethanol production and the pressure corn grain prices placed on shifting other crop and forage land to corn grain production. Yet, current times of increased income present an ideal opportunity to improve resource management. This will be necessary to permit continued profit und...

due to the growing trend of rangelands degradation, study effects of different harvesting intensities on species in order to gain a more fundamental utilization of ranglands can be effective for reclamation and improvement. the purpose of this research was to study effects of different harvesting intensities on key species ajuga chamaecistus.this species has a forage value in the study area. in...

to evaluate the effects of phosphate solubilizing bacteria and chemical phosphorous fertilizer on turnip (brassica rapa) forage yield under limited irrigation regimes, a field experiment was conducted in research farm of college of agriculture and natural resources, university of tehran, in karaj/iran during 2009 growing season. the experimental treatments were arranged as split plots. five lev...

The aim of this study was to compare conventional and organic diets in beef production. Thirty-two dairy beef calves were used in 4 treatments: organic diet with three levels of forage [70% of organic diet with high amount of forage (ORH), 55% of organic diet with medium amount of forage (ORM), 38% of organic diet with low amount of forage(ORL)] and conventional diet (CON). The dry matter intak...

In this paper an efficient three- stage algorithm is developed for software production cost and time estimation. First stage includes a hybrid model composed of COCOMO and Function Points methods to increase estimation accuracy. Second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...

Mix cropping of alfalfa (Medicago sativa) and annual ryegrass (Lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. In this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...

the aim of this study was to investigate the fermentation characteristics and cellulolytic enzymes activities of dromedary camels rumen anaerobic fungi in fed with cultivated and pasture forages. hence, the inoculant of rumen anaerobic fungi was prepared by using specific medium and the gas production, digestibility and enzyme activity of rumen fungi were determined on the basis of a 2 × 2 fact...

abstract. rangelands are mainly used for grazing the livestock in iran, it is essential to specify grazing suitability of rangelands in each region of country, so that it may improve the management policies and approaches for planning and designing current and future plans. the aim of this research was to determine the rangeland suitability for sheep grazing in the watershed of sadegh abad, ker...
