Grading performance of three-year-old Etawa Grade Buck based on semen quality at The Central Java Artificial Insemination Center, Ungaran

Abstract

This research aimed to evaluate and rank (grading) individual Etawa Grade buck with the best semen quality at three years of age based on volume, odor, color, viscosity, potential of hydrogen (pH), mass motility, individual motility, abnormality and concentration. The materials used were the semen of six three-year-old Etawa Grade buck at the Central Java Artificial Insemination Center, Ungaran. Semen collection equipment, as well as tools and substances for macroscopic and microscopic evaluation, were used in this research. Artificial vagina techniques were used for semen collection. Data analysis used the One Way ANOVA method and the Kruskal-Wallis method, then the grading of superior buck is determined by breeding value. The results of the semen quality evaluation namely, the average volume, pH and motility were significantly different (P<0.05), whereas color, viscosity, odor, mass motility, abnormality and concentration were not significantly different (P>0.05). The total breeding value based on the semen quality of each buck from the highest are Garjito (45), Luhung (44), Ardhani (44), Sahasika (44), Bayanaka (43), and Adinata (42). The most superior and best performing three-years-old Etawa Grade buck based on breeding value assessment judged by semen quality is Garjito.
