| ABSTRACT: The aim of this study was to verify the activity of some digestive enzymes in four fish species with different feeding habits. Knowledge of these enzymatic activities can help us to understand the species' digestive processes. The species chosen for this study were Ctenopharyngodon idella (herbivore), Rhamdia quelen (omnivore), Leporinus obtusidens (omnivore) and Hoplias malabaricus (carnivore). The digestive tract of these species was divided into four portions to estimate enzymatic activity: stomach, anterior, mid and posterior intestine. Ctenopharyngodon idella had the highest amylase and maltase activities in all portions of the gut, followed by L. obtusidens . The highest trypsin activity was observed in all gut portions of H. malabaricus,... |

| Os experimentos foram conduzidos para avaliar a digestibilidade ileal (CDILEAL) e total (CDTOTAL) do amido e a atividade das enzimas amilase (ATAM) e maltase (ATMAL) em coelhos de 35 e 45 dias alimentados com amido proveniente do milho ou da raspa de mandioca. Em cada ensaio foram utilizados 20 coelhos da raça Nova Zelândia Branco, sendo dez machos e dez fêmeas, alojados individualmente em gaiolas de arame e distribuídos em um delineamento inteiramente casualizado. Ao final do período experimental, os animais foram abatidos para retirada de uma amostra do conteúdo digestivo de uma porção do jejuno e do íleo. Os CDILEAL e CDTOTAL do amido da raspa de mandioca (59,25±1,38% e 99,89±0,04%, respectivamente) foram superiores ao do milho (54,21±1,51% e... |

| Foram conduzidos dois experimentos para avaliar a digestibilidade do amido e a atividade específica das enzimas amilase (ATAM) e maltase (ATMAL), em duas porções do intestino delgado (jejuno e íleo), em coelhos com idades iniciais de 28 e 49 dias, alimentados com quatro fontes de amido (milho, sorgo, triticale e mandioca, processados ou não por extrusão). Em cada experimento, foram utilizados 64 coelhos da raça Nova Zelândia Branco, distribuídos em um delineamento inteiramente casualizado com oito tratamentos e oito repetições. Ao final do período experimental, os animais foram abatidos para retirada de amostra do conteúdo do jejuno e íleo, além da raspagem da mucosa do jejuno, para determinação da ATAM e ATMAL. O processamento melhorou o coeficiente de... |

| The sustainable composition of diets of high nutritional value is of the utmost importance for intensive aquaculture. Digestion and absorption of nutrients depends on the activity of the digestive enzymes, in particular those located in the brush border membrane of enterocytes, which are responsible for the final stages of breaking down and absorption of nutrients. In the present study, the substitution of fish meal by lupin or rapeseed meal in the diet was evaluated on gilthead sea bream (Sparus aurata) and goldfish (Carassius auratus). The objectives were to compare the activities of intestinal brush border enzymes in both species fed the control and experimental diets. When gilthead sea bream were fed the vegetable diets, significantly lower activities... |

| Twenty-four Holstein steer calves (88 ± 3kg) with abomasal catheters were randomly assigned within blocks to one of four treatments. The treatments consisted of four abomasal infusions: water (control), 4 g/kg BW.d-1 of partially hydrolyzed starch (SH), 0.6 g/kg BW.d-1 of casein, and a mix of SH + casein. The small intestine was collected and five equidistan, 1m sites were identified (duodenum, jejunum 1, jejunum 2 jejunum 3 and ileum). Maltase specific activity in mucosal homogenate and brush border membrane vesicles, SGLT1 protein abundance, and sodium-dependent glucose uptake in brush border membrane vesicles did not differ between the calves receiving different abomasal infusion treatments. However, maltase specific activity in homogenates and brush... |
