a total of 700 day old female broiler chicks (ross 308) were distributed into seven groupsin acompletely randomized designwith five replicates, and 20 chicks in each replicate. dietary treatments, timeof the switch from an unsaturated sunflower oil (sfo) to a saturated tallow (t)dietary fat source, were: 1) sfo for the entire growth period (6 weeks), 2) sfo for 5 weeks followed byt for last wee...
three levels of lysine (90, 100 and 110% of ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. none of the dietary supplements affected the weight gain during the starter and grower periods. although no significant differences were detected between ...
in the name of allah , the compassionate the merciful abstract shath ( blasphemic utterace made during spiritual ) is a complicated concept that deserves reflection in gnosticism and sufism ( mysticism ) and estem and westem scholars have alwaya paid attention to it. although principal essence of gnostic belief is the holy divine law ,gnosticism has pure and unique thoughts . by glancing at t...
two experiments were conducted to determine threonine (thr) requirements of two commercial strains, ross 308 and cobb 500, based on standardized ileal digestibility from 15 to 28d of age. basal diet consisted of wheat, triticale, and corn gluten meal was formulated according to quick chick (2006) to be adequate in all nutrients except for thr. incremental levels of supplemental thr were added t...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
this study was conducted to evaluate the effect of adding a commercial medicinal plant (mp) powder containing garlic (allium sativum) and thyme (thymus vulgaris) to diets that included olive pulp (op), on the performance and carcass characteristics of broiler chicks. a total of 240 day old male ross-308 broiler chicks were allocated into six iso-nitrogenous and iso-energetic dietary groups with...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
in order to study the effect of different levels of β-mannanase enzyme on the performance, blood parameters and carcass characteristics of broiler chicks (arbor acres), an experiment was conducted with 240 checks (44.6 grams average weight) under a completely randomized design with 4 treatments and 5 replications and 12 checks per each replicate. β-mannanase enzyme with the levels of zero (t1 c...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
this experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (pbpm) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. three samples of pbpm produced in ardabil province located in northwest of iran, were provided during one month sampling peri...
