Distinct glycoconjugate expression between dome enterocytes and villus enterocytes in ileum from twelve 3-week-old conventional pigs was examined by the use of twenty one biotinylated lectins with avidin-biotin-peroxidase complex method. Three patterns of staining were seen. First, lectins bind to dome enterocyte and villus enterocyte to approximately equal staining, i.e. DSL, WGA, s-WGA and Co...

the aim of this study was to investigate the effects of dietary garlic on the growth performance, intestinal mucosa morphology, and pulmonary hypertensive response in broiler chickens with pulmonary hypertension induced by 3, 5, 3′-l triiodothyronine. chicks were reared for 42 days and treated with triiodothyronine (1.5 mg/kg diet) and 0 (control), 0.2, 0.6 or 1% garlic powder. intestinal segme...

The cell surface membranes of mitotically active crypt cells from rat intestinal epithelium were found to have glycosyltransferase activities and endogenous acceptors not found on the differentiating villus cells. Rat intestinal epithelial cells were isolated as intact cells from different levels of the villus and crypt areas representing sequential stages of cellular differentiation. Incubatio...

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-...

To evaluate the effect of decreasing dietary protein on growth performance, carcass traits, and intestinal mucosal morphometry, 180 female Hubbard strain broiler chickens were divided into 3 groups and fed 3 isoenergetic diets ad libitum from 14 d of age until slaughter age (49 d). The treatments varied according to 3 protein levels: high-protein diet (HiP, 22.5% CP, DM basis), medium-protein d...

TLR3 signaling is activated by dsRNA, a virus-associated molecular pattern. Injection of dsRNA into mice induced a rapid, dramatic, and reversible remodeling of the small intestinal mucosa with significant villus shortening. Villus shortening was preceded by increased caspase 3 and 8 activation and apoptosis of intestinal epithelial cells (IECs) located in the mid to upper villus with ensuing l...

To investigate the growth performance and small intestinal histological changes in chickens fed sugar cane extract (SCE), 42 layer-type chicks were divided into three groups of 0, 0.05, and 0.10% dietary SCE diets. The growth performance tended to be better in all dietary SCE groups. Intestinal villus height, villus area, cell area and cell mitosis number of the duodenum showed a higher values ...

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 histomorphometry 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 0-2...

BACKGROUND Genetic haemochromatosis is a common hereditary iron loading disorder in humans. The disease is associated with loss of function mutations in the HFE gene. This is thought to change iron stores via increased iron absorption. AIMS In this study we investigated how adaptation of mucosal reductase activity is engaged in this process and how the changes compare with adaptation seen whe...

the present study was conducted to investigate the effect of corn substitution with triticale in grower diets (zero, 50 and 100%) with/without exogenous enzyme supplementation on growth performance, digestive organs relative weight, jejunal morphology and blood lipids of quail chicks. two hundred and forty one-day-old unsexed japanese quail chicks were randomly assigned to a completely randomiz...
