| O objetivo deste trabalho foi avaliar o efeito do piruvato e trolox (forma solúvel da vitamina E) sobre a qualidade espermática pós-descongelamento. Assim, com o intuito de proteger as células espermáticas dos efeitos deletérios da criopreservação,foram considerados os seguintes tratamentos: T1 (Controle)= INRA82-HEPES sem antioxidantes; T2= INRA82-HEPES + 2mM de piruvato e T3= INRA82-HEPES + 120mM de trolox. As amostras de sêmen descongeladas foram avaliadas quanto à motilidade total (MT) e progressiva (MP),a integridades de membrana plasmática e acrossômica, integridade do DNA, à estabilidade de membrana e ao potencial de membrana mitocondrial (Δψm). A adiηγo de piruvato proporcionou resultados superiores (P<0,05) àqueles obtidos com trolox na... |

| ABSTRACT This study aimed to evaluate the addition of Vitamin C, reduced Glutathione and trolox on sperm characteristics of pork refrigerated semen. Six pigs were collected through the technique of gloved hand (10 ejaculates/animals). The semen was diluted in MR-A®. After the previous evaluations, the treatments were added: Control group: diluent only; Vitamin C Group: 200μM/mL Vitamin C; Trolox Group: 200μM/mL Trolox; Glutathione group: 2.5mM/ml Reduced glutathione. The semen was stored in thermal boxes and placed inside the refrigerator at 15oC and evaluated at D0, 12, 48, 72 hours. After 30 hours of incubation, each treatment was divided into two equal fractions and the same concentration of antioxidants was added in one of the parts. The results show... |

| The objective of the present study was to determine the nutritive value, the presence of antioxidant compounds, and the antioxidant capacity of coffee pulp ensiled or non-ensiled. Dry matter (DM), crude protein (CP), ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), and lignin, as well as the antioxidant compounds present in coffee pulp and their antioxidant capacity, were determined. A completely randomized design was used. Data were analyzed by analysis of variance. Ensiling of coffee pulp increased the CP content from 98.6 to 111.6 g kg−1 DM, NDF from 414.6 to 519.5 g kg−1 DM, ADF from 383.9 to 439.3 g kg−1 DM, and lignin from 122.9 to 133.6 g kg−1 DM. Caffeine decreased from 5.72 to 5.02 mg g−1 DM. Three antioxidant compounds were... |
