Item Changes in composition, antioxidant content, and antioxidant capacity of coffee pulp during the ensiling process(Sociedade Brasileira de Zootecnia, 2014-09) Rios, Teodulo Salinas; Torres, Teresa Sánchez; Cerrilla, María Esther Ortega; Hernández, Marcos Soto; Cruz, Antonio Díaz; Bautista, Jorge Hernández; Cuéllar, Cuauhtémoc Nava; Huerta, Humberto VaqueraThe 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 detected. Caffeic acid decreased due to ensiling (16.49 vs 14.69 mg g −1 DM). Gallic acid (2.88 vs 2.58 mg g −1 DM) and chlorogenic acid (62.12 vs 56.00 mg g −1 DM) did not differ, and there was similar antioxidant capacity of non-ensiled (215.66 μmol trolox g −1 DM) and ensiled coffee pulp (206.59 μmol trolox g −1 DM). Despite the decrease in the caffeic acid content due to the ensiling process, it is possible to use either ensiled or non-ensiled coffee pulp for animal feeding because of its high antioxidant capacity.Item Semen quality and reproductive performance of boars kept in pens containing conventional coffee husk as a floor covering(Sociedade Brasileira de Zootecnia, 2016-07) Teles, Mariele Cristina; Pereira, Bárbara Azevedo; Rocha, Luiz Gustavo Pessoa; Resende, Carla Oliveira; Rodrigues, Valéria Vânia; Pereira, Luciano José; Gil, Joan Enric Rodríguez-; Zangeronimo, Márcio GilbertoThe objective of this study was to evaluate the putative effects of the use of coffee husk as floor covering on boar semen quality. Sixteen boars were divided into two groups. The first group was held in a conventional system with a compact floor. The second group was kept on a compact floor covered with coffee pods. The experimental period was 60 days. Levels of caffeine and chlorogenic acid in the insemination doses (ID) before and after 96 h of storage at 15 °C and the reproductive performance (litter size and rate of return to estrus) of these doses after their utilization in a standard artificial insemination protocol were evaluated. The ID from the animals kept in pens containing the coffee pods contained 25.4±8.7 μg/mL of caffeine, whereas no significant amounts of chlorogenic acid were detected. Semen from boars housed with coffee husk showed a significant increase in malondialdehyde levels, which indicates a significant increase in cell membrane peroxidation, after 96 h of storage. There were no significant differences in the other evaluated semen quality parameters when analyzed among groups. Likewise, there was no significant influence of coffee hulls on either the rate of return to estrus or the litter size of inseminated females. The use of coffee husks as floor covering worsens the quality of fresh semen and that of insemination doses stored for 96 h but not the quality of semen immediately diluted; therefore, coffee husks may be used only on farms that use semen immediately processed after collection without affecting the reproductive parameters of breeding stock.
