ABSTRACT
Grapefruits are widely recognized by their extreme sensitivity to develop chilling injury (CI) during postharvest storage at low temperature. Moreover, many cultivars and mutants of grapefruits exhibit important differences in both external and internal coloration, from yellow to deep red, due to a distinctive accumulation of the red carotene lycopene. Thus, in this study the genetic variability in external peel coloration of grapefruits has been used to examine the potential relationship between carotenoid content and composition, and susceptibility to CI. CI increased progressively after 2 weeks storage at 2°C in fruit of the yellow grapefruit ?Marsh? (M) but in the fruits of red cultivar ?Star Ruby? (SR) CI symptoms were exclusively restricted to the yellow areas of the peel. Thus, CI was absent in red peel tissue, even after prolonged cold storage, in which lycopene content was about 14-times higher than in yellow tissue. In addition, SR grapefruits growing under shaded conditions developed an intense external red coloration and accumulated large amount of
lycopene, and were also highly resistant to CI upon subsequent postharvest cold storage. To further explore the mechanisms involved in the resistance to CI induced by lycopene, total antioxidant activity was determined in yellow and red peel tissue of grapefruit, and the potential relationship between carotenoids and the development of CI is discussed. |

Abstract:The goal of this study was to evaluate the rejection rates of Zebu bulls during behavioral assessment (libido and serving ability) and the importance of this step in bull breeding soundness evaluation (BBSE). A total of 1,534 bulls reared in the state of Rio Grande do Sul, Brazil, of Nelore (1,340), Brahman (76), Guzerá (98), and Tabapuã (210) breeds were evaluated. The evaluation consisted of four steps. Step I was the general physical examination, Step II genital tract examination, Step III semen evaluation, and Step IV behavioral assessment of libido and the ability to complete copulation. To evaluate the relationship between the binary variables of approved or rejected during different steps of the BBSE, and age groups (young and mature
bulls), chi-square tests and logistic regression were used. The general rejection rates in the BBSE were 5.64% and 15.20% for young and mature Zebu bulls, respectively. Problems with the sexual behavior (libido and/or serving ability) of bulls accounted for the rejection of 0.46% and 2.29% of young and mature Zebu bulls, respectively. The lack of libido and serving ability was shown to be an important problem concerning the total number of possible causes of Zebu bull rejection during the BBSE. This result suggests that the behavioral step should be performed regularly, rather than being complementary to the standard BBSE in Zebu cattle.

Foram avaliados 1.534 touros, criados no estado do Rio Grande do Sul, Brasil, das raças Nelore (1.340), Brahman (76), Guzerá (98) e Tabapuã (210). A avaliação constou de quatro etapas. Etapa I foi o exame físico geral, Etapa II o exame do trato genital, Etapa III a avaliação do sêmen, e a Etapa IV a avaliação comportamental de libido e habilidade física para completar a cópula. Para avaliar a relação entre a variável binária aprovado ou reprovado durante as diferentes etapas do exame andrológico e as faixas etárias (touros jovens e adultos), foram utilizados os testes de qui-quadrado e de regressão logística. As taxas gerais de reprovação no EAT foram de 5,64% e 15,20% para os touros Zebu jovens e adultos, respectivamente. Problemas no comportamento sexual (libido e/ou habilidade física) dos touros foram responsáveis pela

A falta de libido e de habilidade física mostrou-se um problema importante em relação ao número total de possíveis causas de reprovação de touros zebuínos no EAT. Esse resultado sugere que a etapa comportamental deve ser realizada regularmente, ao invés de ser apenas complementar ao EAT padrão em bovinos zebuínos MenosAbstract:The goal of this study was to evaluate the rejection rates of Zebu bulls during behavioral assessment (libido and serving ability) and the importance of this step in bull breeding soundness evaluation (BBSE).
