background: growth promoters are chemical and biologicalsubstances that are added to livestock food with the aimto improve the growth of chickens in fattening and the utilizationof food, and in this way achieve better production and financialresults. objectives:an experiment was conducted to evaluatethe effects of enzyme complex, probiotic, and their combinationon performance of broilers fed a ...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
The purpose of this study was to investigate the effects of aliphatic sodium butyrate on some blood parameters and growth factors in carp fingerling with an average weight of 10 g. This experiment was conducted for 8 weeks by using four different diets with three replications including: control (without supplement) and three levels of sodium butyrate (0.25, 0.5 and 1%). Feeding was performed fo...

The purpose of this study was to determine the effect giving ratio Calcium Hydroxide (Ca(OH)2) and Magnesium Sulfate (MgSO4) with different doses on growth white shrimp (Litopenaeus vannamei) production in freshwater media. This research conducted by experimental method using Completely Randomized Design (CRD). parameter studied how addition Ca(OH)2 Sulfat lime maintenance container 5 treatment...
The effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (Litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. There was no significant difference in final weight (m...
this study was accomplished to investigate the effect of artemia urmiana nauplii enriched with pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, huso huso. artemia nauplii were enriched with p. acidilactici at a final concentration of 1010 cfu ml-1 in three time dependent treatments as 3 h (t3), 6 h (t6), 9 h (t9), and one non-enriched artemia as ...
The stressing effect of stocking density and rearing time was assessed on shrimp Penaeus vannamei reared intensively in floating cages. Juvenile were stocked 9 m2 cages at 200, 250, 300 ind m-2 for a 25-day grow-out period. Total soluble protein concentration, superoxide dismutase (SOD), catalase (CAT) activities used as stress indicators muscle, hepatopancreas, hemocytes. Two-way ANOVA showed ...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
