1. QUERCETIN SUPPLEMENTATION PREVENTS CHANGES IN THE SEROTONIN AND CASPASE-3 IMMUNOREACTIVE CELLS OF THE JEJUNUM OF DIABETIC RATS
RESUMO CONTEXTO: A serotonina (5-HT) está presente nas células epiteliais enterocromafins (CE), nos mastócitos da lâmina própria e nos neurônios entéricos. A 5-HT está envolvida na regulação da motilidade, secreção, nocepção intestinal, sistema imunológico e inflamação. Objetivo: Avaliar os efeitos do diabetes e da suplementação de que

2. Gut microflora and intestinal morphology changes of broiler chickens fed reducing dietary protein supplemented with lysine, methionine, and threonine in tropical environment
ABSTRACT This experiment aimed to discover the effect of reducing dietary protein supplemented with lysine, methionine, and threonine on growth performance, volatile fatty acid profile, and intestinal villus height and crypt depth of broilers, as well as the microflora counts isolated from broiler chicken faeces. A total of 288-day-old broilers were allocate

3. Effect of probiotic Lactobacillus reuteri XC1 coexpressing endoglucanase and phytase on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens
ABSTRACT This study investigated the effect of transformed Lactobacillys reuteri on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens. A total of 480 broilers were assigned to six treatment groups and fed a phosphorus-adequate diet, a phosphorus-deficient diet, or a phosphorus-deficient die

4. Crude glycerol in diets for Nile tilapia in the fattening stage
Resumo: O objetivo deste trabalho foi avaliar o uso de glicerol bruto como fonte de energia em substituição ao milho, em dietas para tilápia-do-nilo (Oreochromis niloticus) em fase de engorda. Duzentas tilápias-do-nilo (190±4,5 g) foram distribuídas em 20 tanques, em delineamento inteiramente casualizado. Os tratamentos consistiram de 0, 60, 120, 180 e

6. Gut: Key Element on Immune System Regulation
Abstract The gut is the main organ that mediates the contact between antigens with our organism, controlling the immune response against environmental factors, such as microbiota and food. Innate lymphoid cells participate in the gut-associated lymphoid tissue (GALT) maturation during the prenatal and early postnatal periods. After birth, breast milk provide

7. Xylanase for meat-type quails from 15 to 35 days old
ABSTRACT The objective of this study was to evaluate the effect of the supplementation of two xylanases in the diet of meat-type quail on performance, morphology of the intestinal mucosa, metabolization of nutrients, and carcass yield. The experimental design was a completely randomized 2×3+1 factorial arrangement [two metabolisable energy reductions (70 an

8. Histopathological and ultrastructural findings induced by heat-inactivated Lactobacillus plantarum and the culture supernatant on the intestinal mucosa of piglets: an ex vivo approach
RESUMO No presente estudo, foram realizadas análises histológica, morfométrica e ultraestrutural para investigar as alterações da mucosa intestinal em explantes jejunais de leitões expostos a duas cepas e concentrações de Lactobacillus plantarum inativado pelo calor e seus sobrenadantes de cultura. Os explantes jejunais foram incubados durante quatro

9. Imunodetecção de Toxoplasma gondii em tecido placentário de cabras naturalmente infectadas
RESUMO A imuno-histoquímica (IHQ) é considerada uma ferramenta rápida e precisa para a identificação de protozoários, como Toxoplasma gondii, em tecidos fetais e placentários. Neste estudo foi avaliada a imunodetecção de Toxoplasma gondii em tecido placentário de cabras naturalmente infectadas. Foram coletadas e analisadas 80 amostras de placentas

10. Morphological study of the gastrointestinal tract of Larimichthys crocea (Acanthopterygii: Perciformes)
ABSTRACT The present study aimed to investigate the macroscopic and histological structure of the gastrointestinal tract (GIT) of Larimichthys crocea (Richardson, 1846). It consists of esophagus, stomach regions, pyloric caeca, intestinal regions, and rectum. Sixteen tubular light yellowish pyloric caeca of similar sizes were observed in all individuals. The

12. Effects of in ovo injection of lysine and methionine into fertile broiler (parent stock) eggs on hatchability, growth performance, caecum microbiota, and ileum histomorphology
ABSTRACT We investigated the effect of in ovo injection of lysine, methionine, or their mixture into fertile broiler eggs on hatchability, chick weight, growth performance, inner organ development, caecum total aerobic bacteria, E. coli, coliforms, Enterobactericaea, and ileal histomorphology of broilers. Three hundred fertile eggs obtained from 60-week-old
