Protein Kasar Plasma Seminalis Sapi Menurunkan Kejadian Nekrosis Spermatozoa Kambing yang Disimpan pada Suhu Dingin (BULL SEMINAL PLASMACRUDE PROTEIN DECREASING THE PERCENTAGE OF NECROSISIN GOATSPERMATOZOA THAT KEPT IN COLD TEMPARATURE)

The aim of this study was to determine the benefits of bullseminal plasma crude proteinin goat spermatozoa diluent to improve of frozen semen quality.This study consists of three treatments: (i)treatment control (P0,goat semen + diluents ; (ii) treatment I(PI, diluent + goat semen + bull seminal plasmacrude protein (1:1);and (iii)treatment II (PII, diluent + goat semen+ bull seminal plasma crude protein (1:2). All treatments were kept in arefrigerator (5oC) andobserved for necrosis of goatspermatozoa, daily. The highest spermatozoa necrosis was observed in the diluter without the bull seminal plasma crude protein eitheratday 1, 2, 3, 4orday 5. The necrosis was statistically significant different (p<0,05) between P0, PI and PII. withthe lowest percentagenecrosis at PI. In conclusion, the addition of bull seminal plasma crude protein in skim milk diluentwill decrease theincidenceof necrosis ingoat spermatozoa which were kept in cold temperature.
