| 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... |

| Podisus nigrispinus is a generalist predator naturally occurring in agricultural and forestry systems that effectively contributes to the population balance of phytophagous insects, especially defoliating caterpillars. Histological changes were evaluated in the salivary glands and midgut of P. nigrispinus caused by ingestion of systemic herbicide isoxaflutole. These predator females were fed with leaves of eucalyptus plants, Tenebrio molitor pupae or water, contaminated or not by herbicide. Salivary glands and midguts were dissected, processed and analyzed under a light microscope. Activity level and cell morphology of the salivary glands and midgut showed differences among insects fed on plants, contaminated water or pupae. The epithelia of the salivary... |

| ABSTRACT This study explores the differences of appearance and the digestive systems of two birds (Lonchura striata and Copsychus saularis), which have the same eating pattern in staple ingredients. Each bird was caught naturally and euthanized in appropriate manner, followed by morphology survey on bill, duodenum, jejunum, ileum and appearance of the body parts such as Culmen, Claw, Wing, Tarsus, Toe and Tail. The results showed that the appearance feature between them presented significant differences in the beak length, wing length and tail length, which were correlated to their staple feeding habits. In addition, in the digestive system, the length of duodenum and duodenal indexes showed significant differences (p<0.05 or p<0.01), which was... |

| This study aimed at evaluating the effect of the use of different growth promoters on the morphometry and ultra-structure of the intestinal mucosa of 42-day-old broilers. A total number of 36 male Cobb broilers was distributed in a randomized experimental design with a 3 x 3 factorial arrangement, with 3 prebiotic and 3 probiotic sources in the feed, summing up 9 treatments, with 4 replicates each. There was a significant interaction (P<0.01) among the studied factor for villi height (VH) in all intestinal segments, and for crypt depth (CD) in the duodenum and the ileum. In the duodenum, higher villi were obtained in the control group, with the combination of B. subtilis and prebiotics, and with the single use of MOS+OA. No VH differences were observed... |

| This study aimed to evaluate the effects of probiotics and prebiotics of bacterial and yeast origin on the performance, development of the digestive system, carcass yield and meat quality of free-range broiler chickens. Five hundred and sixty male chicks of the strain ISA S757-N were reared from one to 84 days old. The birds were distributed in four treatments according to a completely randomized block design: T1 = Control, T2 = Probiotics and Prebiotics of bacterial origin, T3 = Probiotics and prebiotics of yeast origin, T4 = Probiotics and prebiotics of bacterial origin + probiotics and prebiotics of yeast origin. There were four repetitions with 35 birds per repetition, and the birds had access to a pasture area after 35 days of age. Characteristics... |

| This study characterized the morphology of the digestive tube of five species of sea turtles. We used specimens found dead along the coast of the state Rio Grande do Norte, as well as specimens accidentally killed as a result of pelagic longline fishing. Nineteen animals of the following species were analyzed: Chelonia mydas (Linnaeus, 1758) (n = 9), Lepidochelys olivacea (Eschscholtz, 1829) (n = 6), Caretta caretta (Linnaeus, 1758) (n = 2), Eretmochelys imbricata (Linnaeus, 1766) (n = 1) and Dermochelys coriacea (Vandelli, 1761) (n = 1). After opening the plastron, we removed the digestive organs and described the external and internal morphology of each organ. The esophagus of all species had pointed papillae on the mucosa. The stomach varied in shape... |

| The blood supply in the small intestine of seven Tamandua tetradactyla (Linnaeus, 1758), was studied. The method included preparation of the macroscopic collection report, perfusion of the arterial network with water (40ºC), injection of colored latex (Neoprene 650®, 2350-0003 Suvinil® dye), fixation in formaldehyde (10%), and preservation in ethanol (50%). For description and analyzes, dissection under mesoscopic light and photo documentation were performed. The small intestine of T. tetradactyla is irrigated by the cranial mesenteric artery, the ventral visceral branch of the abdominal aorta. The artery emerges from the retroperitoneum and disperses between the layers of the common mesentery, parallel to the caudal mesenteric artery. The primary cranial... |

| In eusocial bees, workers and queens are diploid (2n), whereas males are haploid (n). However, in some species, including the stingless bee Melipona quadrifasciata anthidioides Lepeletier, 1836, 2n males arise from fertilized eggs resulting from the crossing between a queen and her brother. In the present study, we provide a comparative analysis of the digestive and regenerative cells in n and 2n pupae and adult males of M. quadrifasciata anthidioides. In n and 2n pupae and adult males, the number of regenerative cells/nest was similar. In n and 2n pupae, the mean number of digestive cells/midgut area was 2076 ± 0.60, whereas in adults it was 1234 ± 1.42 digestive cells/midgut area. The nuclear area of the digestive cells was also similar in both n and 2n... |

| Feeding is an important factor for the successful rearing of larvae of the crab species. Further information on the morphological features of the foregut may to reveal larval feeding behaviour and or/whether there is a lecithotrophy in some or even in all stages of the larval cycle. In the present study, the structural development of the foregut and their digestive functions were examined in larvae of two brachyurans, Uca vocator and Panopeus occidentalis, reared in the laboratory. During larval development, the foreguts of the larvae in the first and last zoeal stages and in the megalopa stage were microscopically examined, described and illustrated. The zoeal foreguts of both species were well developed, showing specialization with a functional... |

| This study sought to morphometrically analyze the jejunal wall of protein-malnourished rats administered a probiotic supplement. The sample consisted of recently weaned Wistar rats (Rattus norvegicus) distributed among four groups: animals given a commercial diet (G1, n = 4); animals given the same ration as G1 plus a probiotic supplement (G2, n = 4); animals given a 4% protein diet (G3, n = 4); and animals given the same ration as G3 plus a probiotic supplement (G4, n = 4). After 12 weeks, part of the jejunum was harvested and subjected to routine histological processing. Transverse sections with a thickness of 3 µm were stained with HE, and histochemical techniques were used to assay for glycoconjugates, including staining with periodic acid-Schiff (PAS)... |

| In the latest years more attention has been given to mechanisms for bird adaptation at post-hatching period by management of environmental conditions and formulations of diets offered during this period when digestive, immune, and thermo-regulating systems suffer slight changes. In post-hatching period, digestive system is anatomically complete, but its functionality is still immature in relation to adult birds. The chick immunity depends on maternal antibodies transferred to egg just before laying. In addition, variations within thermal comfort zone might affect initial development of chick. For example, high temperatures may induce hyperthermia with dehydration, while low temperatures may lead to hypothermia responsible by pulmonary hypertension... |
