Abstract
It was investigated about extractability and biological property(ATPase activity) of actomyosin from skeletal muscle of chi(:ken differed feeding period. The extractabilities of actomyosin from pectoral muscle were increased from 184.5 to 1020.1 mg per 100g muscle as feeding period prolonged from 3 weeks to 8 weeks. In case of leg-muscles, extractability was revealed the similar tendency as pectoral muscles. EDTA ATPase activity of actomyosin in various chicken muscles for 3 weeks feeding was 0.6 Brmole Piimg Protein/min., 0.59 for 6 Iveeks feeding and 0.50 for 8 weeks. The
사양기간(飼養期間)이 서로 다른 닭의 골격근에서 actomyosin 을 추출하여 추출성과 생물 활성을 비교하였다. 가슴부위에서 추출한 actomyosin의 추출성은 사양기간(飼養期間)이 3,4,5,6,7주(週)의 순으로 각각 184.5, 364.0, 784.8, 926.1, 985.2, 1020.1 mg/100g 이었고 다리부위는 각각 28.6, 70.8, 137.9, 139.5, 608.3 그리고 646.2mg/100g 이었다. 사양기간(飼養期間)이 3,6,8주(週)인 경우 24시간 추출한 actomyosin의 EDTA-ATPpase활성은 각각 0.68, 0.59, 0.50
