A ten-week experiment was conducted to study the effect of a nanostructure of phytic acid absorber (NPAA) on the performance and protein digestibility in laying hens. A total of 100 Bovans laying hens were randomly assigned to 5 treatments, with 4 replicates, 5 hens each. The experiment was a completely randomized design with 5 levels of NPAA; including zero (T1, as a basal diet (BD)); T2 (BD+ ...

this study was conducted to investigate the effects of in vitro and regeneration of lily (lilium longiflorum) bulb scale by different plant growth regulators in b5 medium in a completely randomized design with factorial arrangement and 4 replications. treatments consisted of indole-3-acetic acid (iaa) and 2,4-d in b5 medium in four concentrations (0, 0.5, 1, 2 mg/lit) and these were combined to...

This study carried out based on a randomized completely design with 10 treatments geranium, eucalyptus and myrtus extraction, in 3 levels (2, 6 and 10 ml in 600 ml of distilled water) and control (distilled water) with 3 replications in 30 plots and each plot with 4 cut flowers. In this experiment traits such as vase life, water absorbtion, fresh weight, dry matter percent, petal protein conten...

laboratory and field experiments were conducted to investigate the relationships between germination characteristics and field emergence in produced seeds of soybean cultivars as affected by under three different soil moisture conditions. the treatments are included water stress [irrigation plants after 50 (normal irrigation), 100 (mild stress), 150 (severe stress) mm evaporation from class a p...

an experiment was conducted to investigate the effects of using different levels of ginger rhizome powder (grp) and turmeric rhizome powder (trp) on production performance and some blood metabolites in laying hens. ninety 103-week old laying hens were divided into 5 treatments in a completely randomized design with 3 replicates and 6 birds in each cage. the birds were fed a corn-soybean meal ba...

in order to evaluate the effect of feeding different levels of vermi-humus supplement (as a source of humic acid) on the performance of broiler chickens an experiment was conducted using 240 broiler chickens (ross 308) in a completely randomized design by four treatments (vermi-humus levels of 0, 0.5, 1 and 1.5 percent) and five replicates of 12 chickens per each for 42 day. the experimental tr...

This study was conducted to investigate the effects of protexin probiotic and aquablend avian antibody on the performance and immune system of broilers. In this experiment, 320 1-day-old male broiler chicks of the Ross 308, with 5 treatments and 4 replications in a completely randomized design were distributed in experimental units (cages). The treatments include: control (C), protexin (P1), pr...
