abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
the effects of dietary supplementation of grape seed extract (gse) and vitamin c on carcass characteristics, gut morphology and ileal microflora in broiler chickens exposed to chronic heat stress were examined. experimental diets included a control diet (without additive), 3 levels of gse (150, 300, 450 mg/kg of diet), and vitamin c (300 mg/kg of diet). each of the five diets was fed to 5 repli...
To test the hypothesis that inclusion of whole cereals in the diet of broiler chickens reduces the severity of a coccidial infection, the effects were investigated, in birds infected with Eimeria acervulina, of feeding a complete pelleted control food, the control food diluted with whole wheat (400 g/kg), or a diet in which ground wheat in the pellets was substituted with whole wheat (400 g/kg)...
This study evaluated the effect of a combination of mannan-oligosaccharides (MOS) and microbial phytase (MP) on growth performance, some blood biochemical metabolites, intestinal morphology and cecal microbial population of ROSS 308 broiler chickens from d 0 to 35 of age. A total of 200 one-dayold broiler chickens (mixed sex) were randomly distributed into four treatments with five replicates a...
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
BACKGROUND: Brain monoamines (such as histamine and dopamine) play an important role in emotions, cognition, reward and feeding behavior. The interactions between histamine and dopamine were studied in many physiological functions but this correlation is unclear in feeding behavior of chickens. The aim of this study was to investigate the interaction of central histaminergic and dopaminergic sy...
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 investigate the effects of olive leaf (OL) on immune response and some blood metabolites of broiler chickens. A total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. Birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% OL powder from 14 to 4...
an experiment was conducted to assess the influences of different growth promoters on performance, carcass characteristic and intestinal microflora of broiler. day-old broiler chicks from arian strain (384) were used in the completely randomized experimental design during 7-42 days of age. eight rations were formulated as a follow 1: control (without growth promoters); 2-control + formic acid (...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
