In conclusion,lacking for choline and methionine led to decrease growth performance decrease and tibia with short disease; Basal diet supplemented with 750 ppm – 1250 ppm Cholin improved Growth performance ,and prevented the occurrence of perosis. Higher dietary choline can alleviate the adverse effects of methionine and choline deficiency.

总结而论，缺乏胆碱与甲硫胺酸会导致生长性能下降和胫骨粗短症；饲粮中添加750~1250 ppm之胆碱可以改善生长性能及防止胫骨粗短症的发生；饲粮添加高剂量的胆碱，可以缓和甲硫胺酸和胆碱缺乏之不良影响。
