Background: Antioxidants of natural origin can be used to improve cryopreservation of semen. Objective: To evaluate the effect of dietary supplementation with Erythrina americana on the seminal characteristics of rams. Methods: Ten rams were randomly distributed in two treatments: l) Group supplemented with E. americana (20% dry matter basis; AEA, n=5), and 2) Control group not supplemented (SEA, n=5). Both diets were iso-proteic and iso-energetic. The feeding period was eleven weeks. Ejaculates were obtained through an artificial vagina and were evaluated fresh (37 °C) and refrigerated (5 °C). Semen volume (VOL) was assessed by visual examination in a calibrated (mm) tube; sperm concentration (CON x106) with a photometer; and mass motility (MM, 1-5), individual motility (IM), normality (N), and live sperm (L) were assessed by microscopic observation. Results: Feeding E. americana did not affect (p>0.05) VOL, CON, MM, and N in fresh semen, but decreased (p<0.05) IM and L. The L and N variables did not differ (p>0.05) among treatment groups in the refrigerated semen; however, IM improved in the AEA group (p<0.05) compared to the SEA group. Conclusion: Dietary supplementation of rams with E. americana reduces sperm quality in fresh semen but is beneficial for the cooling process of refrigerated semen. ; Antecedentes: La suplementación dietaria con antioxidantes de origen natural es una alternativa para mejorar la criopreservación del semen. Objetivo: Evaluar el efecto de la suplementación dietaria de carneros con Erythrina americana sobre algunas características seminales. Métodos: Diez carneros fueron distribuidos al azar en dos tratamientos: 1) Grupo suplementado con E. americana (20%, con base en materia seca; AEA, n=5); y 2) Grupo testigo, sin suplementación de E. americana (SEA, n=5). Ambas dietas fueron balanceadas isoprotéica e isoenergéticamente. El periodo de alimentación de los sementales fue de once semanas. Los eyaculados se obtuvieron mediante vagina artificial y se evaluaron en fresco (37 ... |
