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-...

a study was carried out to evaluate the probiotic activity of bacillus subtilis g1 isolated from fermented pickles in growth performance and disease resistance of hemibagrus nemurus fingerlings at universiti putra malaysia. the probiotic was mixed in feed at doses of 0 (c, control), 3 x 109 (t1) 3 x 107 (t2) and 3 x 105 (t3) cfu g-1 and fed to the catfish fingerlings for nine weeks. results sho...

the present study was conducted to investigate the clinical effects and possible side effects of yarrow extract ( achillea millefolium l.) as feed additive on biochemical blood parameters and growth performance of rainbow trout ( oncorhynchus mykiss ). fishes were treated with 0 (control), 0.1, 0.5 and 1% of yarrow extract for 30 days. plasma alanine aminotransferase (alt), aspartate aminotrans...

this study was performed with growing chicken (14 to 56 d of age) to evaluate the effects of feeding them a barley or triticale-based diet. the treatments were corn diet (1) as a control, hulless barley diet with (5) or without (2) enzyme, triticale diet with (6) or without (3) enzyme and hulled barley diet with (7) or without (4) a commercial β-glucanase enzyme. in a digestibility trial, 21 ma...

Soil microbial fuel cells (SMFCs) are expected as an application to produce sustainable energy. Here, we focused on soil ecosystems, specifically the earthworms which are known to improve soil-fertility by degrading fallen leaves or plant litter. The aim of this study was to investigate the effect of earthworm on power generation of the SMFC. The maximum power density and the internal res...
