    STUDIES ON EVALUATION AND PRESERVATION OF BOAR SEMEN
    (Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2006) KANSHI, SHIVANAND; Singh, M.P.
    In neat semen significant (P<0.01) effect of breeds on the extracellular activity of AST and ALT was recorded which was lower in T&D boar. The effect of breed on LDH and AKP activity was found to be nonsignificant. The mean extracellular level of AST, ALT & LDH did not vary significantly in any dilutors and breeds at any hour of preservation. However the level of AKP varied Significantly (P<0.01) between dilutors and breeds at 72 and 96 hours of preservation. Irrespective of breeds the extracellular levels of AST, ALT and LDH were significantly lower in Lactose egg yolk followed by Kiev and Modena dilutors at 24, 48, 72 and 96 hours of preservation. The level of AKP was significantly higher in Lactose egg yolk. Irrespective of dilutors the extracellular levels of AST, ALT and LDH were higher in Large White Yorkshire at 0 hour and at rest of the hours of preservation the difference was nonsignificant. The level of AKP was significantly higher in T & D at 48 and 96 hours and at rest of the hours of preservation the difference was nonsignificant.
