This study was conducted to investigate the effects of garlic powder (GP) black seed (BS) and plant premix (GP and BS) in the diet on broiler growth performance and intestinal morphology. included 480 Hubbard broiler chicks(day-old). There were 4 treatment groups each consisting of 3 replicates. The four dietary treatments consisted of a control (basal diet), basal diet +0.5% GP, basal diet +0....

Glutamine is a nonessential amino acid that can be synthesized from glutamate and glutamic acid by glutamate-ammonia ligase. Glutamine is an important fuel source for the small intestine. It was proposed that glutamine is necessary for the maintenance of normal intestinal morphology and function in the absence of luminal nutrients. However, intestinal morphologic and functional changes related ...

Snakes provide a unique and valuable model system for studying the extremes of physiological remodeling because of the ability of some species to rapidly upregulate organ form and function upon feeding. The predominant model species used to study such extreme responses has been the Burmese python because of the extreme nature of postfeeding response in this species. We analyzed the Burmese pyth...

Weaning stress caused marked changes in intestinal structure and function. Transforming growth factor-β1 (TGF-β1) and canonical Smads signaling pathway are suspected to play an important regulatory role in post-weaning adaptation of the small intestine. In the present study, the intestinal morphology and permeability, developmental expressions of tight junction proteins and TGF-β1 in the intest...

Varedi, Maryam, George H. Greeley, Jr., David N. Herndon, and Ella W. Englander. A thermal injuryinduced circulating factor(s) compromises intestinal cell morphology, proliferation, and migration. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G175–G182, 1999.—The effects of a 60% body surface area thermal injury in rats on the morphology and proliferation of the epithelium of the small...

Maternal separation (MS) in neonates can lead to intestinal injury. MS in neonatal mice disrupts mucosal morphology, induces colonic inflammation and increases trans-cellular permeability. Several studies indicate that intestinal epithelial stem cells are capable of initiating gut repair in a variety of injury models but have not been reported in MS. The pathophysiology of MS-induced gut injury...

Walker-Smith, John (1972). Archives of Disease in Childhood, 47, 80. Variation of small intestinal morphology with age. A study of small intestinal three-dimensional morphology from 85 childhood necropsies, using the dissecting microscope, has shown that there is a variation in morphology with age. While finger-like villi occurred frequently in the small intestine of neonates, particularly in t...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...

This study was performed to investigate the effects of dietary threonine (Thr). level on performance, metabolizable energy, intestinal morphology, and immune system in coccidian–infected broiler chickens. The diets contained: 88%, 100% (Non challenged (NC) and challenged control (PC)), 112%, 124%, and 136% of Thr requirement according to Cobb 500 recommendation and fed during grower (pre challe...

clostridium perfringens (c. perfringens) is related to gram-positive and anaerobic bacteria. this rod-shaped bacterium produces spores and can cause a wide spectrum of diseases in humans and animals. every of five different bacterium types can lead to different diseases. most of distinct bacterial recognition methods are not completely effective and practical in all condition. the objective of ...
