| The objective of this study was evaluate the influence of feeding bullfrog tadpoles on commercial feed containing 28% crude protein (CP), on their digestive enzyme performance and activities. The experiment lasted 60 days, at the density of one tadpole/L in boxes containing 30 L water. A hundred and twenty tadpoles at the 25 Gosner stage averaging weight and length was 0.046 g and 6.22 mm, respectively, were used. Survival rate, length, final weight, weight gain, feed consumption, apparent food conversion, specific growth rate and activities of chime, amylase, lipase and trypisin were the parameters evaluated, biweekly, in five biometries. Quadratic effect was observed for the length and the weight. There was larger growth of the tadpoles from the 15th to... |

| ABSTRACT We evaluated the effects of a protease supplementation on the growth performance and intestinal health of broilers. Cobb chicks (392; 1-42 d) were divided into four treatments (seven replicates of 14 birds each). There were two feed formulations: a standard diet (SD) and a low crude protein and digestible amino acids diet (Low CP&AA). The two diets were either supplemented (+P) or not (−P) with a protease (Jefo Protease; 1.25 g kg−1). Performance was evaluated by feeding phases (1-7, 8-21, 21-35, and 35-42 d). On day 28, ileum samples were analyzed by a morphometric index for histological alterations (I See Inside Scoring System – ISI). Broilers fed the Low CP&AA had a poor feed conversion ratio (FCR); however, the addition of the protease... |

| ABSTRACT To assess the ability of the collared peccary ( Pecari tajacu ) to digest dietary fiber, four adult male collared peccaries were randomly assigned to a 4 × 4 Latin square design to determine the effects of feeding non-traditional feed ingredients, taken from palm trees with different levels of dietary fiber, on intake and coefficient of total tract apparent digestibility (CTTAD) and mean retention time. Four experimental diets were provided ad libitum: corn and soybean meal-based control diet; corn and palm kernel cake-based diet; corn and peach palm byproduct-based diet; and hay, palm kernel cake, and peach palm byproduct-based diet. The CTTAD of neutral detergent fiber and acid detergent fiber (ADF) were 0.80±0.09 and 0.61±0.21, respectively.... |

| ABSTRACT The objective of this study was to evaluate the alterations in blood biochemical profiles and body condition of dogs after intake of the diet without soybean hull (0%SH) and with soybean hull (16%SH) replacing corn. Twelve Beagle dogs with ideal body condition score (BCS) (average: 5) were distributed in a completely randomized design (six animals per treatment) and received the daily amount of food according to the energy needs for maintenance (g/kg weight0.75). The animals were evaluated on days 0 and 28 in relation to the blood biochemical profiles and body measurements, such as: total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low density lipoprotein (VLDL), triglyceride (TAG), glucose, body weight (BW),... |

| Phenotypic plasticity comprises a central concept in the understanding of how organisms interact with their environment, and thus, is a central topic in ecology and evolution. A particular case of phenotypic plasticity is phenotypic flexibility, which refers to reversible change in organism traits due to changes in internal or external environmental conditions. Flexibility of digestive features has been analyzed for more than a century in a myriad of different species and contexts. Studies in rodents on gut size flexibility have been developed mainly from two different áreas of the biological sciences, physiology and ecology. However, as for several other topics related with physiological ecology, both kinds of studies largely developed along sepárate... |
