1. Effect of an Enzymatic Blend and Yeast on the Performance, Carcass Yield and Histomorphometry of the Small Intestine in Broilers from 21 to 42 Days of Age
ABSTRACT The present study was conducted to evaluate the performance, carcass yield, and histomorphometry of the small intestine of broilers fed yeast sugarcane supplemented with enzymatic blend from 22 to 42 days of age. Seven hundred broiler chicks were distributed in a completely randomized design in a factorial design (2x3+1), two levels of the enzyme bl

2. Feed additives can differentially modulate NF-κB (RelA/p65), IGF-1, GLUT2, and SGLT1 gene expression in porcine jejunal explants
ABSTRACT The intestinal gene expression of RelA/p65 (NF-κB), insulin growth factor 1 (IGF-1), glucose transporter 2 (GLUT2), and Na+/dependent glucose transporter 1 (SGLT1) were evaluated in response to benzoic acid, yeast culture, L-glutamine, and oregano essential oil, using an ex vivo model. Six piglets weighing approximately 20 kg each were sacrificed,

3. UtilizaÃÃo de promotores de crescimento em raÃÃo para frangos de corte / Use of growth promoters in feed for broiler
Two experiments were carried out to evaluate the effects of using distinct growth promoter over the energetic metabolism and performance of poultry farming. Two experimental diets (ND â normal diet according to nutritional requirements and RD â reduced diet, with 5% less of nutrients), supplemented or not with antibiotics and prebiotics from 1 to 10, 11 to

4. Effects of corn particle size and physical form of the diet on the gastrointestinal structures of broiler chickens
The objective of this experiment was to investigate the effects of different particle sizes, expressed as Geometric Mean Diameter (GMD) of corn (0.336mm, 0.585mm, 0.856mm and 1.12mm) of mash and pelleted broiler chicken diets on the weight of the gizzard, duodenum and jejunum+ileum; on the pH of the gizzard and small intestine and on the characteristics of t

5. Efeitos do plasma sangüíneo sobre o desempenho bacteriano e estrutura intestinal de leitões recém desmamados em diferentes idades / Effects of spray dried plasma on wall structure and on the microbiological colonization in the gut of piglets weaned at different ages
Aiming to determining whether the plasma has other effects on piglets weaned at different ages that are not only related to feed intake increased, three trials were conducted. In trial 1, sixteen piglets weaned at 21 days of age were used in an experiment with randomized blocks design with four treatments (diets with 0.0, 2.5, 5.0 and 7.5% of plasma), four r

6. Morphological repercutions of burn injury components of the myenteric plexus in the jejunum of adults rats. / Repercussões morfológicas da lesão térmica corporal nos componentes do plexo mioentérico do jejuno de ratos adultos.
Burn is a determinant factor to alter body structures as the striated muscle. It also determines gastrintestinal mucosal atrophy what produce loss of selective barrier. With histochemical, immunohistochemical and light microscopy methods the myenteric plexus (MP) of the jejunum was evaluated in rats submitted to burn injury. The scalding was performed in 30%

7. Aditivos fitogênicos e butirato de sódio como potenciais promotores de crescimento de leitões recém-desmamados / Phytobiotic additives and sodium butyrate as potential growth promoters of weanling pigs
The antimicrobials growth promoters in the animal feed have been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate the effect of phytobiotic additives, sodium butyrate and even colistina o

8. Efeito de prebiótico, probiótico e simbiótico sobre o desempenho, morfologia intestinal e imunidade de frangos de corte / Effect of Prebiotic, Probiotic and Symbiotic in broiler performance, intestinal morphology and immunity
The market pressures, since consumers require products with high quality, and the possible inducement for the bacterian resistance due to the inclusion of antibiotics as well, have caused the prohibition of the referred antibiotics in animal alimentation. Considering this event, alternatives like prebiotics, probiotics and symbiotics have been emphasized in

9. Anastomose término-terminal no jejuno de eqüinos coberta com retalhos mesentéricos pediculados / Endtoend anastomosis in the equine jejunum covered by pedunculated mesenteric flaps
Resection and anastomosis of the small intestine is commonly performed in horses to treat lesions produced by strangulated obstructions and other diseases. However this procedure is associated with several complications such as peritoneal adhesions, intestinal stenosis at the site of the anastomosis, necrosis of the preserved intestinal stumps, leakage of in

10. Determinação do tempo do trânsito gastrointestinal em Podocnemis expansa Schweigger, 1812 (Tartaruga-da-Amazônia) (Testudines, Podocnemididae) / Determination of the gastrointestinal transit time in Podocnemis expansa Schweigger, 1812 (Amazon turtle) (Testudines, Podocnemididae)
The amazon turtle hás herb-based diet, but it can be fed with a small quantity of animal-based food. Digestion speede of these animals is influenced by both temperature and nutricion status. To understand the digestion process of food in animal organisms, studies on the gastrointestinal tract transit are necessary. The objective of this study was to determi

11. Avaliação dos plexos mioentericos e do transito intestinal em ratos submetidos a lesão por isquemia e reperfusão do territorio da arteria mesenterica superior
Background/Purpose: Early histological changes induced by necrotizing enterocolitis have been extensively studied using animal models. However, infonnation regarding late effects on intestinal motility are lacking. The aim of this study was to investigate the late effects of ischemia-reperfusion on myenteric pIexus histology and intestinal motility.Materiais

12. Antimicrobial agents, probiotics, prebiotics and herbal extracts as growth promoters of weanling pigs / Utilização de agentes antimicrobianos, probióticos, prebióticos e extratos vegetais como promotores do crescimento de leitões recém-desmamados
The purpose of this work was to evaluate the probiotics, prebiotics and herbal extracts as alternatives to antimicrobial agents as growth promoters of weanling pigs, based on the morphometry of organs, fecal score, intestinal microbiology, intestinal histology, nutrient digestibility and performance. Two randomized complete block design experiments were carr
