消除反刍家畜气胀病威胁，提高苜蓿草地生产力，是世界各国苜蓿育种家共同关注的问题。用无气胀病苜蓿品种取代目前生产上使用的老品种，这是未来发展的必然趋势。半个世纪以来，在气胀病机理和抗气胀病苜蓿育种研究领域，虽然不同学者从饲料角度对气胀病成因提出了几个重要观点和研究方法，尤其是加拿大著名苜蓿育种家Ｂ．Ｐ．Ｇｏｐｌｅｎ博士与其合作者在抗气胀病苜蓿育种方面已取得重要进展，但至今各国都没有解决苜蓿气胀病问题。
It is the common concern of alfalfa breeders all over the world to eliminate the threat of swine rumination and improve the productivity of alfalfa grassland. With no blight disease alfalfa varieties to replace the current production of the old varieties used, which is the inevitable trend of future development. For half a century, in the field of alfalfa breeding for the mechanism of the disease of blight and the disease of anti-bursal disease, several scholars have put forward several important views and research methods on the causes of the blight from the point of view of feed, especially the famous Canadian alfalfa breeder. P. Dr. Goplen and his collaborators have made important progress in alfalfa breeding of the anti-bursal disease disease, but none of the countries so far have solved the problem of alfalfa bursting disease.
