An experiment was carried out with 100 broiler birds of the Leghorn breed, aged 20 days. The birds were divided into groups and were given various amounts of methionine--0,5, 2, and 3 per cent with the basic standard mixture. The clinical signs of methionine intoxication were followed up--drowsiness, weakness in the legs, opisthotonus, and twisting of the neck (torticollis) alons with the loss of equilibrium. It was found that with birds receiving 0.5 per cent methionine with the diet the amount of vitamins A, E, and B1 in the blood serum and the liver rose considerably, while with birds given 2 and 3 per cent methionine with the feed the amount of these vitamins dropped essentially. Therepeutic treatment with 3 mg of vitamin E and vitamin B1 each in the course of 4 to 6 days yielded a good effect. An improvement of the general condition and disappearance of the most typical symptoms of methionine intoxication were recorded.
用100只20日龄的来航鸡品种肉鸡进行了一项实验。将这些鸡分成几组，在基础标准混合料中分别添加0%、0.5%、2%和3%的蛋氨酸。对蛋氨酸中毒的临床症状进行了跟踪观察——嗜睡、腿部无力、角弓反张以及颈部扭曲（斜颈）并伴有平衡失调。结果发现，在日粮中添加0.5%蛋氨酸的鸡，其血清和肝脏中的维生素A、E和B1含量大幅上升，而在饲料中添加2%和3%蛋氨酸的鸡，这些维生素的含量则基本下降。在4至6天内每天用3毫克维生素E和维生素B1进行治疗产生了良好效果。记录到鸡的总体状况有所改善，蛋氨酸中毒最典型的症状也消失了。
