Abstract

ABSTRACTThe aim of this experiment is to utilize the liquor of rumen cattle from abattoir as feed additive, assource of phytase enryme, to increase the quality of broiler ration based on local feed materials. Thisexperiment was conducted in two stages. First stage was to identify enzymes in rumen liquor of cattle.The second stage was to characterize and stabilize enzyme which include determination of optimumtemperature and pH of enzyme, examination enzyme resistance to heating at optimum temperature,and studying effect of metal ions and chemical substances. The results of the experiment show 1)optimum precipitation of rumen liquor enzymes from local cattle is reached at the concentration levelof 60 % of ammonium sulphate, meanwhile from imported cattle is obtained at the level of 70 % ofammonium sulphate; 2) general characteristics of phytase enzyme from rumen liquor of local cattlediffers from that of imported cattle; those from the rumen liquor of local cattle has optimumtemperature at 50 cC, optimum pH at 6, resistance to heating up to 180 minutes at optimumtemperature, and needs mostly methal ions as activator; on the other hand, the enzyme from the rumenliquor of imported cattie has optimum temperature at 39°C, optimum pH at 6, resistance to heating upto 180 minutes at optimum temperature; the phytase enzyme needs mostly methal ions as activator,some compounds inhibiting the enzyme activity are EDTA and ~-mercaptoethanol; and 3) activity ofthe phytase
