Abstract

The aim of this work was to establish the standard for goat milk somatic cell counts. The data were obtained from MGEN, which were collected from Dec. 2006 to Nov. 2007. A total of three hundred and forty somatic cell counts from 12 goat milk farms were analyzed. A goat milk grading system by somatic cell count is proposed; less than 1,000,000/mL, 1,000,000-1,500,000/mL, 1,500,000-2,000,000/mL, 2,000,000/mL-2,500,000/mL, and over 2,500,000/mL. Under the grading system, the ratio of first grade goat milk would be 26.2%, and that of the fifth grade would be 11.8%. The first grade ratio is low and the fifth grade ratio is high compared to the cow milk grading system. It is expected that somatic cell counts of domestic goat milk will be improved by the proposed grading system.

본 연구는 최근 웰빙식품으로 소비가 증가하고 있는 산양유의 체세포수 등급제정을 위해 (주)엠젠에 납유하고 있는 12개 목장에서 2006년 12월부터 2007년 11월까지 납유한 산양유의 체세포수를 분석하였다. 프랑스와 노르웨이의 체세포 등급체계 및 우리나라 원유의 체세포 등급체계를 고려할 때, 산양유의 체세포수 등급체계는 1급이 mL당 100만 미만, 2급이 100-150만 미만, 3급이 150-200만 미만, 4급이 200-250만 미만, 5급이 250만 초과로 규정하는 것이 바람직할 것으로 생각된다. 이러한 체계를 가정할 때 우리나라 산양유의 1등급 비율이 26.2%로 다소 낮고, 5등급 비율이 11.8%로 다소 높으나 이를 통해 산양유의 체세포수가 개선될 것으로 기대된다.
