The estimation of semen production based on body weight and scrotal circumference on PO Bull at Singosari National Artificial Insemination Center

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.

Correlations between age of Bali bull and semen production at National Artificial Insemination Center, Singosari - Indonesia

“…In Cholistani Bull Pakistan, Mahmood et al (2014) reported that age of bull had significantly correlatation with semen volume (r = 0.93), negative correlation with sperm concentration (r = -0.94), and with sperm viability (r = -0.87). In Indonesian Ongole Grade cattle, Muthiapriani et al (2019) reported no significant correlation between body weight with semen volume, sperm concentration and sperm motility (r = 0.48, 0.33 and 0.65, respectively) might be due to limited number of sample (n = 9).…”

Hubungan Antara Umur, Bobot Badan, Lingkar Skrotum Dengan Produksi Spermatozoa Sapi Peranakan Ongole

“…Dari segi performa, sapi PO mampu beradaptasi dengan baik terhadap berbagai lingkungan (Standar Nasional Indonesia-SNI, 2015) dan beradaptasi dengan baik pada iklim tropis yang sangat panas (Nursita et al, 2015) dan pakan berkualitas rendah (Muthiapriani et al, 2019;. Berdasarkan hal diatas, sapi Ongole (PO) memiliki potensi besar untuk dikembangkan sebagai sapi potong yang dapat dimanfaatkan untuk memenuhi kebutuhan daging sapi dalam negeri.…”

“…Produksi dan kualitas semen dipengaruhi oleh banyak faktor, meliputi umur , bobot badan (Kumar and Srivastava, 2017), lingkar skrotum (Muthiapriani et al, 2019), Musim (Suyadi et al, 2020) (SNI, 2015). Penimbangan bobot badan dilakukan menggunakan timbangan digital.…”

Hubungan antara Konsentrasi Testosteron, Lingkar Skrotum, Libido dan Kuantitas Sperma Pejantan Sapi Pasundan

“…Pengukuran lingkar skrotum sapi pasundan diperoleh rataan 30,10±1,39 cm. Hasil ini lebih rendah jika dibandingkan dengan sapi PO (36-72 bulan) sebesar 40,11 cm (Muthiapriani et al, 2019). Perbedaan lingkar skrotum dimungkinkan akibat adanya perbedaan umur (Perumal, 2014) dan bangsa (Menegassi et al, 2011;Eriksson et al, 2012).…”

“…Hasil korelasi rendah (P>0,05) ditunjukkan antara lingkar skrotum dengan libido (-0,353; 0,029; -0,231), volume semen (0,452), dan konsentrasi sperma (0,018). Muthiapriani et al (2019) menyatakan bahwa lingkar skrotum tidak dapat digunakan untuk memprediksi volume semen dan konsentrasi pada sapi PO. Lingkar skrotum juga tidak memiliki korelasi terhadap konsentrasi sapi lLimousin dan sSimmental dengan nilai koefisien korelasi sebesar 0,36 (Prayogo et al, 2013).…”
