this research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. in this experiment, 375 one-day old male broiler chickens (ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...

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...

in the present study, chicory root powder (crp) as growth promoter at 1% and 3% levels was supplemented in broilers’ diet to investigate the growth performance and histo-morphometry of jejunum. one hundred twenty, one-day-old male broilers were used in a completely randomized design (crd) with 3 treatments and 4 replicates (10 chicks per replicate). at the end of each period (0-10, 11-24 and 0-...
