SUMMARY This study was performed to evaluate the effect of the inclusion of paprika and marigold extracts in sorghum-based rations on the productivity and egg quality of laying hens. One hundred sixty laying hens were distributed in a completely randomized design in five treatments and in a factorial arrangement (2 × 2 + 1), one control ration based on corn, two levels of paprika extract (0 and 6 g/kg diet), and two levels of marigold extract (0 and 1 g/kg diet) in sorghum-based rations. There was no effect (P > 0.05) of the treatments on the weight, specific weight, and Haugh unit of the eggs and productive performance, but the inclusion of paprika extract resulted in eggs with lower egg pH. The interaction between the control group and the factorial was significant (P < 0.05) to the laying rate, egg mass, and yolk color, whose values were lower with sorghum-based diets with no pigment compared to control treatment. The interaction between the paprika and marigold extracts was significant increasing the height (P < 0.03) and color (P < 0.0001) of the yolk when paprika extract was used, with or without marigold extract. Marigold extract inclusion reduced the percentage (P < 0.02) and thickness (P < 0.01) of the eggshell. As conclusion, the inclusion of paprika extract in sorghum-based diets for laying hens is viable for improving the egg quality.

The method and temperature of storage of a product are the basic agents that make it possible to prolong the post-harvest life of strawberries. In this context, this study aimed to evaluate the use of different packages with the passive modified atmosphere in the post-harvest quality of strawberry (cv. Camarosa). The strawberries were harvested and subsequently transported to the Laboratory of Drying and Post-harvest Storage of Agricultural Products, where they were stored in BOD, at 0ºC, and 90±5% relative air humidity. A completely randomized design was used, in a 3 x 5 factorial scheme (three packages: expanded polystyrene (EPS) packaging + polyvinyl chloride (PVC) film at 0 °C; polyethylene terephthalate (PET) packaging at 0 °C; and without packaging at 0 °C (control) x five analysis: at 0, 2, 4, 6, and 8 days of storage), with four replications per day for each treatment. Averages were compared by Tukey test at 5% probability. The variables, fresh mass loss, pulp firmness, pH, soluble solids (SS), titratable acidity (TA) and SS/TA ratio were analyzed. The tested packages had better results when compared to the control treatment. The use of polyethylene terephthalate (PET) packages at 0ºC had a less fresh mass loss during storage days, lower acidity reduction, and no significant decrease in pulp firmness.
