background: since the prohibition of antibiotic growth promoter in poultry ration by the european :union:, poultry producers have been  trying to replace them by other growth promoters like medicinal herbs. lipia citridora is a medicinal  herb enriched by several powerful phenolic compounds and with antioxidant and antimicrobial properties which lead to enhancing appetite and growth performance...

an experiment was conducted to investigate the effects of using different levels of red pepper powder (rp) and marigold flower powder (mf) on egg production, egg yolk color andsome blood metabolites in laying hens. ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. the birds were fed a corn-soybean...

this study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in ross and cobb broiler chickens. one hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (ross-308 and cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. the experimental grou...

the objective of this study was to determine the effect of different levels of sesame wastes (sw) on performance, milk composition and blood metabolites in lactating dairy cows. in this order, eight multiparous holstein dairy cows were used in a replicated 4×4 latin square design in four periods of 21 days. treatments were control (no sesame meal supplementation), and supplemented with 5, 10 an...

this experiment was conducted to investigate the effects of olive leaf (ol) on immune response and some blood metabolites of broiler chickens. a total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% ol powder from 14 to 4...

tramadol is a centrally acting analgesic drug extensively metabolized in animal species. its clinicalresponse is mainly due to the m1 metabolite, poorly produced in dogs. grapefruit-juice can inhibit themetabolism of different drugs in animals and humans. the aim of the present study was to evaluate thepharmacokinetics of tramadol and its major metabolites after co-administration of tramadol an...

biotic as well as abiotic factors may influence the biocontrol activity and population density of pseudomonas fluorescens. however, limited studies have been carried out on the effects of extracellular metabolites of other competitor bacteria, especially on the biocontrol efficiency of p. fluorescens. a greenhouse experiment was conducted to evaluate the potential of the two p. fluorescens isol...

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...

two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (sap) and irrigation management on seed and essential oil yields of cumin, as well as the impact of water quality on water holding capacity of sap. salinity had a negative effect on the amount of water absorbed by sap (335 and 59 g h2o per g sap, for distilled water and solution of 0.5% nacl...

The genus Rhodococcus is gram positive bacterium which was classified into the family of Nocardiaceae.  The organism can be isolates from different sources, with capability to degrade diverse types of pollutant. Nowadays, scientists reported a few secondary metabolites which are produced by Rhodococci. Hence, the present study tried to isolate Rhodococci from different soil samples with the cap...
