| The internal quality of conventional and ω-3 enriched commercial eggs stored at different temperatures was evaluated. Eggs derived from Isa Brown layers fed two different diets. In Group 1, 432 hens were fed throughout their productive life with a diet based on corn and soybean meal (production of conventional eggs). In Group 2, starting at 22 weeks of age, other 432 hens were fed a diet containing 1.5% of marine algae substrate and 1.8% of fish oil (production of ω-3 enriched eggs). The following parameters were evaluated: Haugh unit, yolk index, albumen pH, and yolk pH. There were no significant differences between conventional and enriched with ω-3 eggs as to internal quality parameters. Only the interaction between storage time and temperature was... |

| ABSTRACT Rice (Oryza spp.), the most important cereal in the world, is grown and consumed in all continents. Brazil is among the top ten producing countries. Stored grains can be attacked by pests (rodents, insects, fungi and mites) that cause serious qualitative and quantitative losses. Because of these losses, one way to alleviate the problem caused by insects during rice storage is the use of resistant materials (grains). Thus, the aim of this study was to evaluate grains from nine different genotypes of rice, in order to identify the existence of materials less susceptible to the attack of Sitophilus zeamais, during 180 days of storage. The mean time of biological cycle (days), susceptibility index (IS) and the number of weevils emerged were evaluated.... |

| ABSTRACT Main stem pruning and fruit thinning are cultivation practices that can influence the yield and quality of the fruit. This study aimed to evaluate the effects of main stem pruning and fruit thinning on the postharvest conservation of Charentais Banzai melons. In the field, the plants were subjected to main stem pruning and fruit thinning, with harvesting done 74 days after sowing (DAS). The fruits were transported to the laboratory where they were cleaned, characterized, and stored in a cold chamber (5 °C and 90 ± 2% RH). In the field, the experiment was designed as a split-plot using a 2 × 4 + 1 factorial design, with two levels of main stem pruning (pruned and unpruned), four levels of thinning times (42, 45, 48, and 51 DAS), and a control... |
