Ongole Crossbreed (Peranakan Ongole/PO) cattle is a mating product between Javanese Cattle (white local cattle) and Ongole cattle from India. PO cattle is a broiler and worker type thanks to its large body size, have a strong power, patient and able to adjust towards environmental differences. In addition, mother-cow's reproduction activity is quickly return to normal after childbirth, meanwhile its male cow has good sperm quality.

In order to improve quality of PO cattle's genetics and productivity, a lecturer at Faculty of Animal Husbandry of Kanjuruhan University of Malang, Enike Dwi Kusumawati, S.Pt., MP had a research in artificial insemination. The research is a prerequisite to grab doctorate degree. The student of doctoral program at Faculty of Animal Husbandry of Brawijaya University had an open dissertation examination, Wednesday (23/Aug/2017) in sixth floor of meeting room building V. In the event, the Unikama Rector Dr. Pieter Sahertian also attended the exam.

A research titled "Spermatozoa Fertility of Ongole Crossbreed Cattle after Sexing in Different Methods" used experimental methods in two stages. The first stage was sexing, dilution, cooling, freezing and the spermatozoa quality test. It aims to know spermatozoa quality produced by sexing when it was still in liquid form and already frozen. The cement sample derived from PO cattle in Centre of Cattle research, Grati-Pasuruan.

Meanwhile, the second stage was conducted to examine the fertility using artificial insemination in 135 cows at PT. Widodo Makmur Perkasa, Cianjur. The artificial insemination used different cement treatment, such as cement without sexing, SGDP (Sentrifugasi Gradien Densitas Percoll/Centrifugation of Percoll Density Gradient) and SPT (Sedimentasi Putih Telur/egg hite sedimentation). Each treatment was applied for 45 cows. Afterwards, observation on NRR (Non Return Rate) numbers in periods of 20-30 days and CR (conception rate) in 90 days after artificial insemination was accomplished.

In the stage indicated that examination of pregnancy in three-month ages obtained various results. Such as 21 pregnant cows were produced from artificial insemination using non sexing cement (control), 14 pregnant cows used cement sexing SPT and 18 pregnant cows used cement sexing SGDP.

A conclusion from the research was quality and structure of spermatozoa after sexing and post thawing process using SPT indicated a better result compared with SGDP methods. Meanwhile spermatozoa fertility indicated that results of SGDP sexing was better than sexing SPT based on products of artificial insemination by liquid cement using CR analysis. [dta/Humas UB/trans.
