Abstract: Using 2-3 weeks kid abomasa as material, the ultrasound intensity, extraction time, NaCl concentration and pH value in extracting solution and ratio abomasum to extracting solution were studied by ultrasounic method. The results showed that the main factor affecting kid rennet activity during extraction was ultrasound intensity / then NaCl concentration, extraction time and ratio absomasum to extracting solution in order. Kid rennet activity reached peak with ultrasound intensity 30 W·cm-2, extraction time 40 min, NaCl concentration 8%, pH value 3, ratio abomasum to extracting solution.1:15.

Key words: Ultrasound extraction, Kid rennet, Rennet activity, Influencing factors
