this experiment was conducted to evaluate the effect of different levels of crude protein and threonine on performance, carcass characteristics and immune system of broiler chickens during starter (7-24) and grower (25-42) periods. a total of 288 male broiler chicks of ross 308 strain were used in a completely randomized design with factorial arrangement (2×4) with three replicates in each trea...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
The objective of this study was to evaluate the effects of replacing dry ground corn with crude glycerol on intake, apparent digestibility, performance, and carcass characteristics of finishing beef bulls. A completely randomized block design experiment with 25 d for adaptation and 100 d for data collection was conducted, in which 3,640 Nellore bulls (367 ± 36.8 kg; 18 ± 3 mo) were blocked by b...
The objective of this research was to evaluate the effect increasing levels associated glutamine and glutamic acid on growth performance intestinal development Nile tilapia, Oreochromis niloticus, fingerlings. Five isoproteic (~344.70 g kg−1 crude protein) isocaloric diets (~3,925 kcal gross energy) were developed containing 0, 5, 10, 15, or 20 in extruded diets. Fish (n = 2,000, mean body weig...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Effect of Adding Whey and L. Buchneri to Alfalfa Silage on In Vitro Gas Production and Degradability
Ensiling alfalfa is difficult due to some restrictions such as low water soluble carbohydrate concentration and high buffering capacity. This study was conducted to document the effects of supplementation of alfalfa silage with fresh whey and bacterial additive on gas production, dry matter, organic matter and crude protein degradabilities by in vitro method. Experimental treatments included th...
an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...
Introduction: Infectious diseases, mainly caused by bacterial agents, are one of the most common causes of death worldwide. A significant number of these agents have been resistant to one or more antibiotics; some of them are multi-drug resistant and others are extensively drug resistant. Various antimicrobial and anticancer compounds have been reported from the venom of various species of scor...
In order to investigate effect of cutting on chemical composition and degradability parameters of sorghum silage an experiment was don. Sorghum forage was used from first and second cutting for ensiling. Ensiling was done in plastic buckets (2.5 kg weight) for 80 days. The result showed that dry matter, neutral and acid detergent fiber in silage of second cutting was higher (P<0/01) and crude p...
