this experiment was conducted to determine the effects of sodium bentonite litter supplement and stoking density on performance and litter quality using a total of 252 broiler chicks in completely randomized design with 6 treatments which were arranged factorially (3×2) and 4 replicates. experimental factors included: stocking density (14; low and 18; high /birds per m2) and three levels of sod...

in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...

the application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. in this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. the five treatments were control (withoutamendment), municipal solid waste compost (mc), vermicompost...

in order to surveying the effect of feeding propolis on performance, feed intake and digestibility in holstein suckling calves, the experiment was designed in a completely randomized design with 4 treatments (diet) and 10 replicates (cattle) during 52 days. treatments included: 1. control (without monensin in starter and without propolis in milk); 2. starter without monensin and 500 ppm soluble...

to evaluate the efficiency of nanocid as growth promoter in comparison antibiotics and with organic acids on performance and intestinal morphometric characteristics of broiler chickens, 240 male broiler chicks of one dayage (ross 308) were utilized in an experiment of a completely randomized design of 4 treatments and 4 replicates. the experimental treatments included: 1) control (no additives)...

karyotypes of eleven iranian populations of trigonella foenum-graceum were investigated. somatic chromosome numbers of examined populations were determined as 2n = 14. chromosomal parameters were examined as follows: long arm length (tl), short arm, total chromosome length, arm ratio, r-value, form percentage of chromosome, total form percentage of karyotype. chromosomes were mostly metacentric...

the experiment was done in a factorial design based on completely randomized with three factors and five replications in vitro. the first factors, plant extract (nine plant species), the second factor, solvent (5 solvent) and the third factor, concentration (3 concentration) were considered. in pot condition, the experiment was carried out in factorial based on completely randomized design with...

the effects of different levels of whole cottonseed (wcs) on feedlot performance and morphology of small intestine were studied in a completely randomized design with four diets containing 0, 4, 8 and 16 percent wcs on 20 chaal male lambs for 90 days. the metabolisable energy and proteins contents of rations were equal. number and dimensions of different types of villi and depth of crypt gland ...

effects of chromium nano particles (nanocr) on performance and meat quality of japanese quail under physiological stress was determined by  using 360 birds in a completely randomized design with six treatments, four replicates and 15 birds per each, during  17- 35 d of age. the tratments were negative control (non-stressed), and five groups under physiological stress which fed on diets suppleme...

scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. one of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. this postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (pal) and peroxidase (pod) enzymes activity in stem bending of two gerbe...
