to study the possible use of phytase and yeast (saccharomyces cervisiae) in corn-soy bean meal base diet with different levels of available phosphorous in arbor acers broiler chicks, an experiment was conducted with 264 day old chicks of an average weight of 44.6 grams each. a completely randomized design of 6 treatments and 4 replications (11 chicks per replicate) for periods of starter, growe...
Scott, Norris, and Heuser (1) and Daniel, Scott, Heuser, and Norris (2) reported that the unknown growth-promoting activity in several natural products for LactobaciUua casei was multiple in nature. The latter investigators proposed the existence of two unknown factors as an explanation for the wide variations in response to different antipernicious anemia liver extracts obtained with L. casei ...
Various studies in poultry nutrition have indicated that certain diets based on vegetable products are deficient in a hatchability-promoting or growth-promoting factor which is associated with certain animal protein materials (l-4). Hammond and Titus (5) studied the effect of a diet of corn, soy bean meal, alfalfa meal, butyl fermentation residues, minerals, and vitamin Ds on chicks and found t...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
The aim of this study was to investigate the effect of different levels of soybean meal peptides on body weight gain, feed conversion ratio, feed intake intestinal morphology and microbial population in broiler chicks. In a completely randomized design 280 one-day-old Ross 308 male broiler chicks were allocated to 7 treatments with 4 replicates and 10 chicks per replicate. Broiler c...
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...
This study aimed to investigate the effect of commercial phytase (SMIZYME PHYTASE) between diets containing 20 and 40 percent soybean meal on growth and body composition of rainbow trout. For this experiment, 300 Rainbow trout with an average initial weight of 6.5 ± 0.43 g were randomly distributed in 18 aquariums (15 fish per tank). Three replicates per treatment were considered. The fish were...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
the present study was carried out to investigate the effect of different levels of triticale with/ without enzyme cocktail (xylanase and β-glucanase) on performance of broiler chicks. five hundred day old male broiler chicks (ross 308), assigned to a factorial arrangement (5×2) with a completely randomized design with 5 replicates of 10 chicks each. the factors included 5 levels of triticale (0...
