| Determinou-se a composição química dos farelos de algodão 28,0; 38,0 e 46,0% de proteína bruta e os coeficientes de digestibilidade aparente (CDA) pela tilápia do Nilo da matéria seca, proteína, aminoácidos, energia, lipídeo e minerais. Os CDA foram determinados, usando-se dieta-referência purificada, contendo 0,1% do indicador óxido de crômio-III. As rações-teste continham 60,0% da dieta-referência e 40,0% dos alimentos em estudo. Os resultados mostraram diferença (p < 0,05) entre os CDA dos nutrientes dos farelos de algodão. Os CDA dos três farelos de algodão foram: matéria seca = 53,45 a 54,32%; proteína = 71,56 a 74,81%; energia = 53,80 a 58,60%; lipídeo = 85,37 a 89,11%; fósforo = 33,75 a 34,50%; cálcio = 41,21 a 43,75%; ferro = 62,02 a 79,85%;... |

| High energy extruded diets were formulated to contain the same level of protein supplied either by soy protein concentrate (SPC) or fish meal. Three experiments were performed in order to measure voluntary feed intake and feed waste, faecal losses and soluble losses of nitrogen and phosphorus in rainbow trout (average body weight: 100 g). Voluntary feed intake and growth performance of fish fed with demand feeders were not different when diets contained 0, 50 or 75 % SPC instead of fish meal. Total replacement of fish meal by SPC led to a significant decrease in feed intake and resulted in poor growth. This was partly due to methionine deficiency in the SPC based diet. With the addition of crystalline DL-methionine in the diets, an improvement of feed... |

| The objective of this study was to evaluate the processing of millet grain provided at two supplementation frequencies for grazing beef cattle during the dry season on nutritional parameters. Five rumen-cannulated crossbred steers, with 24 to 26 months of age and average body weight of 428.6±26.06 kg, were assigned to a Latin square design (5 × 5) in a 2 × 2 + 1 factorial arrangement, as follows: two forms of millet grain (whole grains - or ground; WG - GG), two strategies of concentrate supplementation (daily distribution - 7X; or three times a week - 3X) and a control treatment (mineral mixture - MM). Animals were kept in five paddocks of 0.24 ha each with Marandu grass pastures. Concentrate supplements were supplied at 2.00 and 4.66 kg/animal/day for... |

| Hemicellulosic agricultural by-products such as corn stover (CS) are highly available materials which represent an opportunity to develop value added products. Native Aspergillus niger GS1 was used for solid-state fermentation (SSF) on alkali pre-treated CS (ACS) aimed to optimize xylanolytic enzymes production, and their effect on in vitro ruminal and true digestibility of ACS. Enzyme production was empirically modelled using a fractional factorial design 2(9-5), and the resulting significant factors were glucose, yeast extract and two mineral salts, which were arranged in a Draper-Lin optimization design at two levels. Predicted optimum xylanolytic activity of 33.6 U (mg protein)-1 was achieved at 48 hrs of SSF, and was validated by confirmatory... |
