known for its antioxidant properties, which is associated with the prevention of cancer. Raw tomatoes and tomato?based products are important sources of dietary lycopene. This study aimed to evaluate the integration of diafiltration and reverse osmosis pro?cesses to concentrate tomato pulp and to obtain a lycopene?rich extract with a high antioxidant capacity and a low molecular weight. Diafiltration was efficient in desalting the tomato pulp, maintaining the lycopene concentration of the tomato at the same level as the whole tomato pulp. The permeate flux of the diafiltrated tomato pulp was 29.5 L·h?1·m?2 and the concentration factor of lycopene was 2.4. Additionally, it was found that the antioxidant capacity increased at the same rate than the lycopene content. |

Abstract: Under conditions of high temperature, humidity, and incidence of solar radiation, dairy cows use behavioral changes as a strategy to decrease the metabolic heat production at pasture. The objective of this study was to evaluate the behavioral and physiological responses of Gyr and Girolando (5/8 Holstein 3/8 Gyr, and 1 2 Holstein 1 2 Gyr) dairy cows submitted to environments with and without shade. The experiment was conducted at Embrapa Cerrados (Technology Center for Dairy Zebu breeds?CTZL), Brasilia, Distrito Federal?Brazil, with 48 Gyr and Girolando cows total in the lactation group, with low to medium milk production, in full sun or shade with Eucalyptus urograndis (267 plants/ha−1). The physiological and behavioral characteristics evaluated were panting score, superficial temperature, and time spent grazing, ruminating, and lying down. Other traits included skin and coat thickness, hair diameter, density and length, and predominant coat color. In addition, body measurements, such as body length, the height of withers, chest circumference, and shin circumference, were measured. Shaded cows had 34% longer rumination times than cows in full sun (p = 0.01). With a temperature-humidity index ranging from 79 to 83, the rumination time was 1.7 times higher in cows under shade (p = 0.01) during a 24-h period of observation. There were no significant differences in the grazing time between the environments, but lying time was 23% longer in cows under the sun (p = 0.01). The panting score was not influenced by the environment (p = 0.17). Girolando cows had a 35% higher panting score than Gyr cows (p = 0.01) regardless of the environment. The panting score increased two and a half times during the afternoon compared with the morning (p = 0.01). The surface and rectal core temperatures had significant differences between treatments and time of the day. Body measurements were not different between cows in both environments, but there was a difference between breeds. The use of trees in pastures with a silvopastoral system for dairy zebu cows is indicated to improve grazing behavior, as well as time spent ruminating and lying down.
