abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
this experiment was conducted to evaluate the effects of different levels of dried lemon pulp (dlp) on performance, carcass traits, blood biochemical and immunity parameters of broilers. in this experiment 240 of broilers (ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. experimental diets included: 1) ...
a study was conducted to compare the growth performance as well as blood and carcass variables of two broiler strains reared in a conventional broiler house and a modified greenhouse equipped with cooling pads and tunnel ventilation system. eight hundred day-old chickens of two commercial strains (ross 308 and lohmann) were selected and placed in 8 floor pens (4 pens of 50 broilers for each ...
This study evaluates the effects of different levels of guanidinoacetic acid (GAA) supplement on growth performance and gut morphology in broilers (Ross 308 strain) raised at high altitude (2100 m). A total of 300 one-day-old male broiler chicks (Ross 308 strain) were used in a completely randomized design with five treatments and four replicate pens of 15 birds in each. Five dietary treatments...
in a completely randomized design, the effect of four iso-protein and iso-caloric diets containing different levels (0, 8, 16 and 24%) of processed broiler litter was studied on the fattening performance of 60 holstein male calves (with initial weight of 309±9kg and about 8-9 month age) for a period of 200 days. at the end of the experiment, all animals were slaughtered and then the carcasses, ...
increasing academic and professional language demands around the world are not a deniable fact. the purpose of this study was to investigate english language needs and communication needs of the chemistry students at master and ph.d. levels at the iranian universities. in this research, different methods were used including un-structured interview, structured interview, and two sets of question...
This experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. This study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...
In order to investigate the effect of phytase and copper supplementaion on growth and carcass composition of common carp (Cyprinus carpio L.), in a completely randomized design with 3 ×2 factorial arrangement with three replicates the experimental diets including three levels of phytase 0, 500 and 1000 (FYT) kg-1 and two levels of copper 0 and 15 mg/kg were tested. Diets contained 0.72 percent ...
The effect of dietary lipids and Clostridium butyricum supplementation on circulating lipids and the transcription of selected genes involved in lipid metabolism were investigated in broiler chickens. One hundred and sixty-day-old broilers (Arbor Acres) were divided into four treatment groups in a 2 × 2 factorial arrangement and fed four diets with two lipid sources (soybean oil or fish oil) an...
This study aimed at assessing the effect of pelleted and expanded maize-based feeds prepared with different moisture levels (ML, 0.8 1.6%) particle size (PS, 650 850µ) ingredients on metabolizable energy, ileal digestibility amino acids broiler performance. A total 720 one-day-old male chicks Cobb strain were used. The experiment was performed over a period 40d (days) birds received water feed ...
