this experiment was conducted to evaluate the effect of different dietary enzyme supplemented non-starch polysaccharides on growth and physiological traits of broilers. 625 one day old ross-308 broiler chickens were allocated randomly to 5 treatments with 5 replicates using a crd statistical design through 1 to 21 and 22 to 42 days of rearing period. treatments were included control, wheat, whe...
the effect of yeast culture (saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 brown bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg me (metabolizable energy) feed. three groups were supplemented with 3 different levels of commerci...
Four wheat-based diets with either a low soluble content of non-starch polysaccharides (NSPs, 13 g/kg); viscosity, LV) or high NSPs (33.5 g/kg; HV), and without exogenous xylanase (XYL), were fed to male Ross 308 broiler chickens from 7 21 days age. The enzyme was supplemented at 100 FXU/kg diet, its preparation based on endo-1,4-beta-xylanase produced by Aspergillus oryzae. Each diet eight pen...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
BACKGROUND Resistant starch (RS) is part of potato starch that is not digested in the gastrointestinal tract. RS4 is a chemically modified starch (for example by oxidation and esterification) and physically (by heating). OBJECTIVE The study was aimed at determining the effect of resistant starch on lipid metabolism and activity of hepatic enzymes in Wistar strain rats fed high-fat diets conta...
One hundred grams fat, based on blends of beef tallow and soya oil (0:100, 20:80, 40:60, 60:40, 80:20 and 100:0) which corresponded to dietary ratios of unsaturated to saturated fatty acids (U:S ratio) of 5.47, 3.23, 2.11, 1.45, 1.00 and 0.69, respectively, was incorporated into a rye-based broiler diet (610 g kgÿ1). All diets were tested without or with supplementation of a xylanase-containing...
The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...
the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
