| ABSTRACT The study has been conducted over a period of 4 years, on a total number of 133 dogs, all of those expressing gastrointestinal disorders. Ultrasound and endoscopic examinations were performed in all dogs in order to assess any significant correlations between ultrasonographic and endoscopic findings. The results confirm a significant correlation between the presence of diarrhoea and increased thickness of the large bowel wall, with P<0.5. Another extremely significant correlation we observed is the one between increased thickness of large bowel wall and loss of layering at this level, with P<0.5. Upper GI endoscopy revealed that dilated lacteals in the duodenum are significantly associated with the presence of diarrhoea, P<0.5 and, more... |

| O objetivo neste estudo foi avaliar os componentes não-integrantes da carcaça de novilhos superjovem e jovem terminados em confinamento. Foram utilizados 24 novilhos castrados, 12 com idade média inicial de 8,1 meses e 12 com 20 meses, pertencentes às categorias superjovem e jovem, respectivamente, e abatidos com idade média de 13,1 e 22 meses. O peso de carcaça estipulado foi de 180 kg e a espessura de gordura subcutânea mínima pretendida foi de 3 mm. O peso de carcaça e a espessura de gordura subcutânea reais foram de 180,30 kg e 3,08 mm e 187,39 kg e 2,94 mm, respectivamente, para novilhos jovens e superjovens. Os animais jovens apresentaram maior peso absoluto e relativo dos pulmões (p < 0,05) em comparação aos superjovens (3,96 e 3,37 kg; 1,31 e... |

| 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 digestive wall consists of mucosa, submucosa, muscularis, and adventitia. No major differences appeared in the structure of the tunica, epithelial cell types, connective tissues and musculature glands of L. crocea GIT. The mucosal epithelia in the oesophagus has longitudinal branched folds with frontward and hindmost zones. The gastric tunica mucosa has a characteristic folded structure and can be... |

| ABSTRACT This study described anatomical, histological and histochemical features of the mucosal layer of the digestive tract of Tilapia sparrmanii Smith, 1840, an omnivorous freshwater fish endemic to Southern Africa. This species exhibited a short thick oesophagus with long deep longitudinal folds (466.68 ± 16.91 µm), and a thick (173.50 ± 10.92 µm) muscular layer that allow the passage of large food items. The mucosa was lined with stratified secretory epithelium rich in goblet cells that secreted neutral and acid mucins. The stomach was a sac-like structure with simple tubular glands surrounded by connective tissue. The mucosa was lined with simple columnar epithelium and the lamina propria exhibited a well-developed layer of gastric glands that... |

| The present study compared some morphometric parameters of the digestive tract of four teleosts with different feeding habits: traira (Hoplias malabaricus, carnivore), silver catfish (Rhamdia quelen, omnivore), hassar (Hoplosternum littorale, omnivore), and grass carp (Ctenopharyngodon idella, herbivore). The digestive tract was removed from fish collected from nature and fixed for some morphometric analyses, such as: intestinal quotient, intestinal area quotient, vilosity height, digestive somatic index, and hepatosomatic index. Grass carp showed the highest values of intestinal quotient and height vilosity. On the other hand, the intestinal area quotient was higher in traira than in the other species. The intestinal quotient can be used to estimate the... |

| ABSTRACT Cost and environmental restrictions limit the use of fishmeal (FM) in aquafeeds and plant protein (PP) sources. Soybean by-products are important alternative; however, their antinutritional factors may reduce fish growth. This study evaluates the effect of FM substitution for PP (soybean meal and soy protein concentrate) in diets of dourado (Salminus brasiliensis), a promising species for fish farming and empirically considered highly tolerant to PP-based diets. A control diet was formulated to contain 20 % of fishmeal and 61 % of plant protein (SBM) and other five diets with decreasing FM graded levels (16 %, 12 %, 8 %, 4 %, 0 %), which were replaced by soybean protein concentrate (SPC), comprising six treatments and four replicates. Fifteen... |

| The objective was to evaluate the performance, relative organ weight, morphometry, intestinal length and pancreatic enzyme activity of broilers receiving neonatal supplementation. A total of 900 Cobb 500 broiler chicks was housed in 30 boxes of 2.5 m². The treatments were divided in a completely randomized design with six replications, and consisted of five inclusion levels (0.0, 2.5, 5.0, 7.5 and 10 grams per bird). The supplement used was based of amino acids, vitamins and minerals, which was provided on the ration on the first day in the housing. Statistical analysis was performed using SAS (2008) and when significant broken down using a polynomial regression. Due to the inclusion of the neonatal supplement in the period from one to seven and one to 21... |

| O uso de probiótico na alimentação animal tem sido indicado, por reduzir a mortalidade resultante da colonização intestinal por micro-organismos patógenos, melhorar o desempenho e as características de produção sem deixar resíduos na carne. O experimento teve como objetivo isolar, a partir de amostras de fezes de suínos na fase de aleitamento, cepas de lactobacilos visando sua identificação como probióticos. Foram isoladas 92 colônias, posteriormente submetidas à prova de catalase e 60 tiveram resultados negativos. Estas colônias negativas foram submetidas à coloração de Gram foi avaliada sua morfologia. Destas, 16 apresentaram formas de bacilos. Esses isolados foram comparados pela sua habilidade de resistência em pH 3,0, crescimento na presença de sais... |

| The aerobic bacterial flora in the gut of turbot larvae and their influence on larval survival was examined. Two turbot experiments were run with six replicates each time. Large variation, from 0% up to 44%, was observed in the survival percentage of turbot larvae. There was no correlation between the number of bacteria present in the gut of turbot larvae and the larval survival rate. During both experiments, all replicates followed nearly the same rate of bacterial development in the gut of turbot larvae going from circa 10<sup>2</sup> CFU larva<sup>-1</sup> just before first feeding at day 3 post hatch to 10<sup>5</sup> CFU larva<sup>-1</sup> at day 9 post hatch.In total, 127 bacterial isolates from 12... |

| ABSTRACT The present study evaluated the effects of early post-hatch feeding on the growth and development of the gastrointestinal tract (GIT) of mule ducks reared in the humid tropics to five days of age. A total of 120 newly hatched mule ducklings were selected and randomly assigned to four treatment groups. Each with 30 birds, (T1, T2, T3, and T4) is based on four feeding regimes (feed accessed at 3, 24, 36, and 48 hours post-hatch) for five days. The ducklings were euthanized each day and the parameters: small intestinal samples were processed for histological analysis and histometrical parameters including villi length and width, crypt width and depth, and the number of goblet cells per villus was measured, statistically analyzed using ANOVA and... |

| The ultrastructure of the gastrointestinal tract of Nile perch was described using Transmission Electron Microscopy standard procedures. Investigations revealed the presence of mucous cells, blood vessels and oil droplets plus several nerve cells and muscle bundles in the oral cavity. Further observations revealed columnar epithelial cells in the oesophagus, with a ragged surface, high electron dense cytoplasm, intercellular spaces, mitochondria and mucus granules. The lamina propria of the oesophagus was composed of loose connective tissue, blood vessels, nerve cells and several leucocytes, while the muscularis externa was composed of striated muscle bundles with the a Z line, A band and I band. The stomach was characterized by mucosal glandular cells... |
