Abstract This study aimed to determine the effect of dietary oregano ( Origanum vulgare ) essential oil (EO) on growth performance, digestive enzyme activity, intestinal histomorphology, and microbiota Black Sea salmon juvenile Salmo labrax) . Fish were fed diets different levels EO such as 50, 100, 200, 400 mg kg −1 For this purpose, a total 675 fish distributed randomly in triplicate into 5 e...

The study was planned to determine the comparative efficacy of leaf extract of Azadirachta indica, Cichorium intybus and Moringa oleifera, on haematology, intestinal histomorphology and nutrient digestibility in broilers. Day old broiler chicks (n=180) purchased from a commercial hatchery were reared in a group for one week (adaptation period). At day 8, these birds were individually weighed an...

The ban or severe restriction on the use of antibiotics in poultry feeds to promote growth has led to considerable interest to find alternative approaches. Probiotics have been considered as such alternatives. In the present study, the effects of a Lactobacillus mixture composed from three previously isolated Lactobacillus salivarius strains (CI1, CI2 and CI3) from chicken intestines on perform...

in this investigation, diabetes was induced in adult male sprague-dawley rats by single intraperitoneal injection of streptozotocin (stz) at 45 mg kg-1 of body weight. a group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. the results revealed that, in the untreated diabetic rats, the body and testicular weigh...

introduction: the use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. in this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.   materials and methods: for this work, 40 pregnant balb/c mice were randomly allocated to one c...

for this study the jejuni of 50 adult (2-4 years), apparently healthy iranian river buffaloes were collectedfrom the abattoir for gross morphology, histomorphology, and histomorphometry. our statistical analysisrevealed that, there are significant (p

Abstract Salinity is one of the important factors affecting physiological state crustaceans in marine environments. Lipid plays major roles energy supply and main sources essential fatty acids for membrane integrity, which critical adaptations to changes salinity. Here we evaluated effects salinity (medium, 23 ppt low, 4 ppt) dietary lipid source (fish oil, FO soybean SO) on intestinal health c...

Although histomorphology has made significant advances into the understanding of cancer etiology, classification and pathogenesis, it is sometimes complicated by morphologic ambiguities, and other shortcomings that necessitate the development of ancillary tests to complement its diagnostic value. A new approach to cancer patient management consists of targeting specific molecules or gene mutati...

The study aimed to assess the effects of dietary supplementation microencapsulated L. acidophilus and plantarum their combination on growth performance, organ development, diarrhoea incidences, blood profiles, intestinal histomorphology microflora in weaned piglets. For that, 160 piglets with an average body weight (BW) 8.52 ± 0.15 kg were divided into four groups (40 piglets/group) allotted on...

The use of toxic and less bioavailable inorganic selenium can now be supplemented with an alternative organic source from bacterial species in nutrition for human animal benefit. This study investigated the effects sources on laying performance, egg quality characteristics, intestinal morphology, caecum microbial population, digesta volatile fatty acids hens.
