LEVERAGE FACTORS OF ECOLOGICAL SUSTAINABILITY ON EPIDIDYMAL SPERMATOZOA UTILIZATION FROM INDONESIAN CATTLE IN RUMINANT SLAUGHTERHOUSES

Abstract

The utilization of epididymal spermatozoa of original Indonesian cattle in the ruminant slaughterhouse (Rumah Potong Hewan-Ruminansia or RPH-R) service business unit is still not widely carried out, and is partial, and has not described sustainability in a harmonization manner that includes environmental, social, economic, regulatory and technological dimensions. The utilization of epididymal spermatozoa in the management of the RPH-R service business unit produced is still limited in its sustainability in the ecological dimension. This paper is based on research that aims to analyse the leverage factors for the utilization of epididymal spermatozoa in the management of the RPH-R service business unit. Sustainability status of epididymal spermatozoa was analysed using the Rap-CattleSlaughterhouse method with the Multi Dimentional Scaling (MDS) technique, leverage analysis, dan Monte Carlo analysis, It was started with the preparation of diluent, testicular/epididymal collection, organ preparation, spermatozoa collection, semen evaluation, semen processing, freezing and spermatozoa quality testing after freezing. Epididymal samples were taken from RPH-R in Bogor, Yogyakarta, and Bali in 2019. The results showed that the sustainability of the epididymal spermatozoa in native Indonesian animals (cattle) at RPH-R in Indonesia includes ecological dimension. The sustainability index of the ecological dimension indicates a sustainable status (> 50%) which includes 9 attributes, namely testicular physique, fresh semen pH, semen color, semen consistency, spermatozoa motility, spermatozoa movement, spermatozoa concentration, spermatozoa viability, and spermatozoa morphology. Of the 9 attributes that function as leverage, the most important is the movement and concentration of epididymal spermatozoa.
