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.

Abstract

Ongole Crossbred cattle or more popular known as Peranakan Ongole (PO) cattle is one of local breeds cattle in Indonesia. For improving the population and genetic quality, superior bull with high capacity to produce semen is seriously required. This study aimed to find out the estimation value of semen production of PO bull based on body weight and scrotal circumference. A total sampling of 9 bull candidates of PO cattle available at National Artificial Center (NAIC) Singosari, Malang, Indonesia were used in this study. The method used was case study. Scrotal circumference was directly measured as a primary data. While body weight, semen volume, semen concentration and sperm motility were collected from BBIB Singosari from secondary data. Data was analyzed using simple linear regression. The results showed that with the limited number of samples, there is no significant correlation (P>0.05) between body weight and scrotal circumference on semen volume, semen concentration, and sperm motility.  It was concluded that with limited number of samples involved in this study, there was no significantly on semen production based on body weight and scrotal circumference on PO bull. The suggestion was to improve the correlation value and significant result. The number of samples should be increased.
