This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) protein resources (soy rapeseed meals) gut morphology digestibility broiler chickens. Three hundred eighty-four male Ross-308 chickens were used a 23 factorial arrangement treatments according completely randomized design. The morphological e...

This study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, pH value of gastrointestinal (GI) tract and small intestinal morphology of laying hens. The experiment was a completely randomized design with 160 laying hens strain (W-36) from 32 to 42 weeks of age, with five treatments, four replicates an...

Changes in the morphology of the small intestinal mucosa and enterocyte dynamics were examined in posthatch chicks through 12 d. At hatch, enterocytes were round and nonpolar; however, within 24 h posthatch, enterocytes lengthened and exhibited more typical morphology. Crypts were rudimentary at hatch and by 48 h invagination was completed and crypt numbers increased by branching and fission, w...

The addition prebiotics in broiler diets can benefit digestion and nutrient abortion. objective of the present study was to evaluate effects moringa leaf powder agave inulin on growth performance, intestinal morphology, slaughter traits chickens over 40 d grow-out. A total 280 broilers (Ross 308) aged 1 were randomly allocated 4 treatments, with 7 replicates each 10 chicks per replicate: T1 = c...

Changes in small intestinal morphology, in the indices of cellular development, and in the activities of some mucosal enzymes were examined in broilers from hatch through 14 d. In addition the effects of holding birds without access to feed for 36 h and of deutectomy were examined. Development of the intestine was rapid from 2 d after hatch although rates of development were different in duoden...

ABSTRACT: This study evaluated the effect of three inulin levels (0.1%, 0.2%, 0.4%) supplemented as a substitute for an antibiotic growth promoter (AGP, zinc bacitracin) and control in guinea pigs raised human consumption. Fifty 14-day-old male were used. Productive parameters (weight gain, total dry matter intake, feed conversion ratio (FCR)) intestinal morphology duodenum, jejunum, ileum at s...

An electron microscopic study of the morphology of fat absorption in the duodenum of normal and fat-fed mice supports the view that all absorbed fat passes through the cytoplasm of absorptive cells. The Golgi complex plays an important role in the transport of fat across these cells.

We examined the age-related changes of calbindin D-28k (CB)-immunoreactive neurons and overall populations of neurons in the myenteric plexus of gerbil duodenum using whole mount preparations and immunohistochemistry. The circumference of duodenum increased age-dependently. CB-immunoreactive neurons were observed in all groups, and most of them had the Dogiel type II morphology. The fully devel...

an experiment was conducted to study the effects of dietary levels of extruded full fat soybean (effsb) on performance, blood metabolites and intestinal morphology of broiler chickens. a batch of ffsb was wet extruded at 155 °c, 15 seconds to provide the extruded full fat soybean (effsb) sample. one hundred and forty four d-old ross 308 male broiler chicks were divided into 12 groups with 12 bi...
