| ABSTRACT The objective was to evaluate the influence of coffee husks as floor covering on the aspects of animal welfare such as behavioral characteristics, body surface temperature, and salivary cortisol levels of stabled boars. Sixteen boars were housed in individual stalls; eight were maintained in a conventional system with a concrete floor and eight were maintained on a concrete floor lined with coffee husks. The experimental period was 60 days. All animals were filmed two days prior to the start of the experiment, on both the 7th and 60th days after exposure to coffee husks, and finally two days after the removal of the material. During this period, the number of times that the animals ate, drank, stood, sat, lay down, and dug was recorded.... |

| Two experiments were conducted to evaluate the performance, the energy and nutrient balance and economic viability of production of growing pigs fed diets with reduced levels and phytase. In experiment 1, 60 barrows and gilts (initial weight 25 ± 1.72 kg) were housed in a randomized block design with three diets, ten replicates and two animals per experimental unit (one male and one female). One of the diets was formulated with a reduced level with phytase and evaluated in comparison to a positive-control diet that was formulated according to the nutritional recommendations for animals of this breed, and a negative-control diet without phytase. The different diets did not affect feed intake, but the diet with phytase promoted better final weight, daily... |

| This study aimed at evaluating the effect of ractopamine (RAC) on metabolism, zootechnical performance, body composition, and behavior in Wistar rats submitted to acute and chronic restrain stress. The oral dose of 5 mg/kg of RAC was administered in periods of 0, 7, 14, 21, and 28 days. The elevated plus-maze test (EPMT) was used for behavioral assessment. Blood, carcass and viscera characteristics were evaluated. Insulin-dependent glucose transporters (GLUT-4) were semi-quantified by Western Blot in epididymal adipocytes. RAC periods associated with chronic stress increased the GLUT-4 protein expression in adipose tissue in a time-dependent manner (P=0.01), i.e., the longer the RAC addition period, the higher the GLUT-4 concentration in chronically... |

| The aim of this article was to evaluate the in vivo mechanism of action through which ractopamine reduces the amount of adipose tissue in carcass of animals fed diets supplemented with this drug. Literature search was carried out, using the keywords Ractopamine, lipogenesis, lipolysis, fatty acid and adipose tissue. The scoring system was designed for the adequacy of the methodology. A total of eight papers were found - all published in the English language. The determination of lipolysis and lipogenesis was carried out using different methods - from the quantification of non-esterified fatty acids in the blood to molecular analyses of adipose tissue. The review analysis suggested that, at least in the pigs, the use of this drug reduced lipid deposition in... |

| ABSTRACT The aim of this study was to assess the sperm quality and testicular histomorphometry of Wistar rats supplemented with extract and fractions of fruits of Tribulus terrestris L. The ethanolic extract was obtained by dynamic maceration of spray-dried fruit. This extract was fractionated by liquid-liquid partition, using increasing polarity solvents. Twenty male rats were separated in four groups, with five rats in each group. The control was supplemented with distilled water, while the others were daily given the ethanolic extract, hexanic or aqueous fraction soluble in methanol in a dose of 42 mg.kg-1.day-1 for 70 days. Sperm was obtained from the right epididymal tail for the analysis of motility, count, morphology and viability. The testicular... |

| ABSTRACT: This study aimed to evaluate the effects of substituting wheat bran (WB) by corn gluten feed without steep water (CGF) in cats feeds regarding the nutritional value of the diet, stool characteristics, time of food passage through the gastrointestinal tract (GIT), intestinal gas production and concentrations of short chain fatty acids (SCFA) in blood and faeces. Twenty eight cats were distributed in a randomized block design with four treatments (0, 2.6, 5.3 or 8.0% CGF, based on dry matter, substituting for WB) and seven replicates. Substitution of WB by CGF decreased (P<0.01) the digestibility of acid detergent fibre without influencing (P>0.05) the digestibility of other nutrients and apparent metabolizable energy. There was also no... |

| The need for suitable diets in chickens, considering the ideal protein concept associated with phytase, is important in order to improve the productivity of birds. The aim of this study was to assess the need for the correction of amino acid levels in the diets of broilers, by using different combinations of crude protein (CP) supplemented with phytase. For performance, eight days old Cobb 875 broiler chicks, with initial body weights of 155 ± 1.4g were used. The birds were distributed in a completely randomised design with seven treatments (nutritional plans) and five replicates of 25 birds. For the metabolism trial, 300 birds were selected which were also distributed using the same design, but with five, four and three birds per experimental stage: 8-21... |
