| This research was conducted to evaluate the agronomic characteristics and chemical composition of Gliricidia sepium (Jacq.) Steud grown under different residual heights in different seasons. The experimental design used was a complete randomized block in a split-plot. The plots consisted of three residual heights (70, 90 and 110 cm), and the subplots were four seasons (fall, winter, spring and summer) with four replicates. There was no (P>0.05) interaction between season and residual heights for agronomic characteristics. However, these features were influenced by the cutting season, with no significant effect (P>0.05) on residual height. Significant effects (P<0.05) were observed for dry matter, mineral matter, acid detergent fiber and... |

| ABSTRACT The apparent digestibility coefficients (ADC’s) of dry matter (DM), crude protein (CP), and gross energy (GE) of conventional feedstuffs (cottonseed meal-CSM, soybean meal-SBM, wheat bran-WHB, corn-COR) and regional alternative feedstuffs (common bean residue meal-CBR, mesquite meal-MES, pasta by-product meal-PBM) were determined for hybrid juvenile tambacu Colossoma macropomum × Piaractus mesopotamicus. The apparent DM and GE digestibility of feedstuffs decreased (p<0.05) as fiber content of the ingredients increased. No differences (p>0.05) were found among ADC’s of PBM and COR. The lowest CP ADC among energy sources was observed in MES; the lowest CP ADC among plant protein sources was observed in CBR. Information about the ADC’s of... |

| Abstract Fish consumption is low in Brazil and several factors justify this fact, among them the lack of practicality in preparation. Thus, this study aimed to investigate the relation between the price and the nutritional characteristics of the processed fish products. Correlations between price and nutritional value of 18 different processed fish products were established, comparing nutritional parameters between in natura and processed fish. The results showed that protein features moderate positive correlation to price. The processed fish products analyzed showed lower protein content and higher contents of energy, lipids and sodium compared to in natura fish. |

| The chemical composition, antioxidant potential and antimicrobial activity were studied in six walnuts (Juglans regia L.) cultivars (cv. Franquette, Lara, Marbot, Mayette, Mellanaise and Parisienne) produced in Portugal. Concerning their chemical composition the main constituent of fruits was fat ranging from 78.83% to 82.14%, being the nutritional value around 720 kcal per 100 g of fruits. Linoleic acid was the major fatty acid reaching the maximum value of 60.30% (cv. Lara) followed by oleic, linolenic and palmitic acids. The aqueous extracts of walnut cultivars were investigated by the reducing power assay, the scavenging effect on DPPH (2,2-diphenyl-1-picrylhydrazyl) radicals and b-carotene linoleate model system. All the walnut extracts exhibited... |

| This experiment was carried out to evaluate the effects of the row spacing between corn plants on silage quality. Different spacing between corn rows (40, 60, and 80 cm) was used, but the population of plants was maintained around 65,000/ha in all treatments. Analysis of variance was carried out and means were compared by Tukey's test at 5% of probability. A reduction in row spacing provided better spatial distribution of plants, but did not alter morphological composition or dry matter production. The corn with most equidistant spatial distribution (lowest row spacing) showed an increase in lignin concentration, neutral detergent fiber, and total carbohydrates, and showed a decrease in total digestible nutrients when compared with 80 cm row spacing.... |

| ABSTRACT The objective of this study was to determine the apparent digestibility coefficients of energy, protein, and amino acids in protein ingredients by pirarucu juveniles. A test was conducted with six protein ingredients: meat and bone meal, fish meal, hydrolyzed feather meal, poultry by-product meal, soybean meal, and corn gluten meal. Three repetitions were used for each tested ingredient. A reference feed was used with 430 g kg−1 crude protein and 19.63 kJ g−1 gross energy. The test feeds consisted of the replacement of 30% of the reference feeds with the test ingredients. Chromium oxide was added to the feeds at 1 g kg−1 as an external marker. Eighteen juveniles with an average weight of 235±36 g were used. The best apparent digestibility... |
