the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...
An experiment was conducted with 264 Cobb 500 day-old chicks in order to study the effect of different substitution levels of soybean meal (SBM) with extruded soybean (ESB) and vitamin E supplement on performance and carcass characteristics of broiler chicks. This study was conducted in a 4×2 factorial arrangement with 8 treatment and 3 replicates of 11 broiler chicks per each replicate in a co...
this study was conducted to investigate the effect of dietary soy isoflavones (isfs) on growth performance, blood parameters and tibia ca and p content of broiler chickens. a total of 240 as-hatched day-old ross 308 chicks were used in a completely randomize design with four treatments (0 (control), 25, 50 and 100 mg/kg of isf), three replicates and 20 birds per each replicate for a period of 4...
The objective of this study was to investigate the effect of maize source and complex enzymes containing amylase, xylanase and protease on performance and nutrient utilization of broilers. The experiment was a 4×3 factorial design with diets containing four source maize samples (M1, M2, M3, and M4) and without or with two kinds of complex enzyme A (Axtra XAP) and B (Avizyme 1502). Nine hundred ...
This experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. For doing this experiment, 320 one-day old chicks of the Cobb 500 strains, in a Completely randomized design with 4 treatments and 4 replicates were used. Experimental diets include: control diet (without the guggul), control die...

this experiment was carried out in order to study the effect of ionophore anticoccidial drugs (salinomycin, maduramycin and their combination) and the comparison of those effects on the performance, carcass characteristics and concentration of some minerals of serum in broiler chicks. this experiment was included four treatments: 1) basal diet, 2) basal diet with 60 mg/kg salinomycin, 3) basal ...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
this experiment was conducted to evaluate the effects of caffeine and trans-cinnamaldehyde (tc) on growth performance, hematological parameters, stress hormones, immune response, and some blood parameters of broiler chickens. three hundred fifty 1-d-old broiler chicks were randomly assigned to 7 dietary treatments (five pens/ treatment of 10 male broilers each) in a completely randomized design...
