Abstract

Ongole Grade cattle is one of local cattle in Indonesia.This study was aimed to analyze the effect of bull age and season on semen quality of Ongole Grade cattles macroscopically (sperm motility, and sperm concentration) and microscopically (semen ejaculate volume) to support the policy and management on improvement of semen production. Data were collected from 533 ejaculates of 10 bulls aged 3, 4, and 5 yr at Singosari National Artificial Insemination Center(SNAIC). The 4-year-old bulls hadhighestsperm motiliy and semen ejaculate volume. The lowest ejaculate volume was reported in Ongole Gradecattlesaged 3 yr. Sperm motility and concentrationweresignificantly higher (P<0.01) in wet season than dry season. In conclusion, the bull age and season should be considered by Singosari National Artificial Insemination Centerwhen collecting the semen, especially on bulls aged 3 yr old and in dry season.

Abstract

The aim of this research was to analyze the correlation of age of Bali bull to the body weight and semen qualities. The materials were 50 Balibulls data collected from 2012 to 2018. Therecordeddatawere consisted ofsemen productions (n = 1304) and body weight (n = 1544). The observation was conducted to analysis the interrelationship between the Bali bulls age and body weight (BW), to the semen volume (SV), individual motility (IM) and sperm concentration (SC). The obtained data was analyzed with One-Way ANOVA analysisby using SPSS 24 and followed with Duncan’s Multiple Range Test to determine any significant differences. The correlation between Bali bulls age (the independent variable) and semen quality (the dependent variable) was computed by using Pearson correlation method and presented in linear regression models. The results showed that the Bali bulls agesignificantly affect (P<0.05) the BW from the age of 1 to 10 years old. The age also showed a significant effect (P<0.05) on the semen qualities. The age correlated significantly (P<0.05) with BW, SV, IM, SC were 0.658, 0.386, 0.134 and 0.086, respectively. Inconclusion,the age of Bali bull could be used as an indicator todetermineits BWand semenqualities.
