Intestinal morphology and brush border hydrolase activities were determined along the small intestine of young adult (three months, n = 10), mature (12 months, n = 10), and senescent (29 months, n = 15) rats. The intestinal segments of the senescent rats contained higher mucosal mass and protein content (p less than 0.05) compared with the young and mature animals. A significant reduction of vi...
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-...
this experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. one hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

the aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. in this study, 450 day-old female broiler chickens (arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. on day 14 of the experiment,...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
In order to reduce the risks of antibiotic use in poultry diets, the use of alternative additives such as probiotic and prebiotic compounds has attracted the attention of researchers. 128 quail chicks were randomly assigned to study the effects of different levels of synbiotic additive (KidiLact®) on performance parameters, immune response and histology of small intestine in Japanese quail...
This study was conducted to compare the effects of dietary supplementation of Sodium Gluconate (SG), Mannan Oligosaccharide (MOS) and Potassium Diformate (PDF) on growth performance and small intestinal morphology in nursery piglets. One hundred forty four female piglets (11.69±0.71 kg) were divided into 4 treatments with six replicates of six pigs each. The pigs received a control diet or diet...
