Pengaruh Penambahan Plasma Seminalis Sapi Simmental terhadap Motilitas dan Viabilitas Spermatozoa Domba Ekor Gemuk setelah Ekuilibrasi pada Proses Pembekuan

Abstract

The aims of this research was to determine effect of addition Seminal Plasm of simmental bull to motility and viability of ram’s spermatozoa after equilibration on freezing process. This research consists of three treatments. Control treatment (PO) were diluter + ram’s spermatozoa (without seminal plasma). Treatment I (PI) were diluter + ram’s spermatozoa + bull’s seminal plasma (1:1), treatment II (P2) were diluter + ram’s spermatozoa + bull’s seminal plasma (1:2). All of treatments was observed of motility and viability of ram’s spermatozoa after equilibration. The motility’s result was (PO) 55,8 + 3,7, (P1) 64,1 + 3,7, and (P2) 70,0 + 3,1. The viability’s result was (PO) 64,4 + 3,2, (P1) 71,5 + 4,1, and (P2) 83,9 + 3,4. The results showed that highest rate in maintaining motility and viability of ram’s spermatozoa among all of treatments was P2. It can be concluded that addition of seminal plasm of simmental bull with the ratio 1: 2 is effective in maintaining motility and ‘viability of ram’s spermatozoa after equilibration.
