Abstract: In order to produce bezoar rapidly and improve output, the plastic web for special purpose, bacteria culture and so on were planted into the gall-bladder of Nanyang cattle by surgical operation, which had no effect on the growth, reproduction, field work, plumpness and health of the Nanyang cattle .In 12,18,24 and 36 months after the planting, average bezoar output of a cattle were 6.44g, 10.93g, 16.72g and 28.32g respectively .The new technique has the advantages of rapid formation and rich production of bezoar with high quality that is as good as natural .A statistical analysis shows that the yield of bezoar is closely direct related to the period of cultivation ,the regress equation about the yield per cattle and period of cultivation is y1 =-2.27+0.7819x ,the regress equation about a cattle’s yield per month and period of cultivation is y2 =0.4074+0.011x .In terms of the two equations ,we are able to calculate the yield of bezoar.
