the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
this experiment was carried out using 200 ross 308 broiler chickens in a completely randomized design with 5 treatments and 4 replicates. the true metabolisable energy of the barley hulls were determined using cecectomized roosters.the dry matter, true metabolisable energy, ash, ether extracts, crude protein, crude fiber, ndf, adf, ca and total p content of barely hulls were: 92%, 978 kcal/kg, ...
two trials were carried out to compare the effect of different levels of vitamin premix, in two raising systems of floor and cage, on performance and meat quality of broiler chicks. the chicks were fed with adjusted diets as based on wheat and barley for duration of 29 to 42 days. trial 1 was carried out through an employment of 288 male broiler chicks (ross 308) in 4 treatments and 4 replicate...
this experiment was conducted to evaluate the effect of the addition of a multi enzyme (natuzyme-p) to corn-soybean based diets and to determine the enzyme's nutrient equivalency on broiler chicks’ performance. ninety six day-old male broiler chicks were randomly assigned to a number of 24 battery cages in a completely randomized design. the chicks were grown up to 6 wk of age. six diets (...
In order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from Cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. Treatments were the diets as follow: 1) diet for...
An experiment was conducted to evaluate the effects of replacement of barley grain with barley hydroponic fodder on blood metabolites and milk production of lactating Saanen goats. Eight dairy goats (45± 1.5 kg of live body weight and 3 months of lactation (88±6 days in milk)) were allocated to 4 experimental diets including the control diet and diets consisting of 37, 66 and 100 percent replac...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
this experiment was conducted to evaluate the effect of barley green fodder produced by hydroponics system on the performance of feedlot calves. in a completely block randomized experiment, 24 cross bred (holstein×local) male calves were assigned randomly to one of the two treatments (diets) that were either control (grain barley) or hydroponic barley green fodder (bgf) that was included to...
this experiment conducted to evaluate the effect of different methods of force molting on performance, egg quality of laying hens with one hundred eighty of 52-wk old hy-line layer in completely randomized design with six treatments, five replicates for 90 days. treatments include 1 - feed withdrawal (fw), 2 - 50 percent alfalfa meal: 50 percent layer ration, 3 - 75 percent alfalfa meal: 25 per...
This experiment was conducted to evaluate the effect of barley cultivars and their feeding form on performance, jejunal digesta viscosity, nutrients digestibility and blood parameters of broiler chickens. A total of 512 day-old chicks (Ross 308), as mixed sex, were assigned to experimental treatments using a completely randomized design with factorial arrangement (4×2) for a period of 42 days. ...
