Potential of Flamboyant Flower (Delonix regia (Boj. ex Hook) Raf) Extract to Maintain Post-Dilution Quality of Aceh Cattle (Bos taurus indicus) Spermatozoa

Abstract

The objective of this research was to investigate the effect of flamboyant flower extract as a natural antioxidant on sperm quality of Aceh cattle after dilution and equilibration. Fresh semen was collected from 2 healthy bull aged 3.5-4 years old. The research took place in BIB Laboratory. The method used was CRD (Completed Randomized Design), with 6 treatments and 5 replications each The treatments (m/v) were 0%, 0.05%, 0.10%, 0.15% and 0.20% of flamboyant flower extracts. The method used was CRD (Completed Randomized Design), with 6 treatments and 5 replications each. The treatments (m/v) were 0%, 0.05%, 0.10%, 0.15% and 0.20% of flamboyant flower extracts. The data obtained were analyzed by analysis of variance (ANOVA). Parameters evaluated in this study were motility, viability, plasma membrane integrity, and abnormality. Results showed that there was an insignificant effect (p>0.05) of flamboyant flower extract on the quality of Aceh cattle spermatozoa. The best percentage of motility and viability, 80.0% and 88.4%, respectively, were found at P3 (0.15% flamboyant flower extract). In can be concluded from the research that the addition of 0.15% (m/v) D. regia flower extract was able to maintain sperm quality of Aceh cattle to be used in the artificial insemination program.
