Rlean meat percentage is one of the most important economic traints in pig breeding programs. myostatin is a negative regulator of skeletal muscle growth. null or low activity of myostatin, individual muscle of mutant amimals would show a large and widespread increase in skeletal mass. myostatin null animals have significantly larger diameter or more quantity of fiber skeletal muscle. the phenotype was termed double muscling. in order to probe the relation between myostatin and high lean meat rate and plump - hipped trait, we sythesized the c ' 80 amino acids coding sequence of porcine myostatin and costructed the cloning and expressing vector of it
肌生成抑制素（ myostatin ，即mstn ）是近幾年來（ mcpherrona . c等， 1997 ）發現的骨骼肌生長的負調控因子，它主要在骨骼肌中表達。其活性的喪失，會引起動物肌肉的過度發育，肌纖維直徑變大或肌纖維數增加，表現為雙肌癥狀。肌生成抑制素研究的突破將對豬、肉雞、肉牛等畜禽生產性能的提高具有特別重要的意義。 -

「商業秘密」做為智慧資產的新成員，是隨著高新技術產業急速發展下應運而生的一種智慧財產權，不同於一般傳統知識產權如專利、著作權與商標，商業秘密是以保密性做為其最顯著的法律特徵，而其擁有的涵蓋面強、可擴充性與極大的彈性發展等特性，更是具備現代高新技術產業急速發展與成長的特殊要求，是以目前以高新技術產業見長的經濟發達國家均對商業秘密的保護有不同程度的法律規范，並不時強化商業秘密保護法規的力度，主要是在保護本國高新技術產業的同時，能得以維持國家經濟競爭力。 -
