The effect was studied of various concentrations of ammonia (5, 20, 50 and 100 ppm) on 20-day old chicken broilers for 120 min. The birds were killed in order to study the protein content in the liver, heart musculature, and blood serum as well as the content of the free amino acids and tryptophane. Followed up was also the transaminase activity of the liver and heart musculature and the activity of GOT and GPT. It was established that ammonia does not alter the content of proteins in the investigated organs and blood serum. A dependable increase in the concentration of the free amino acids in the blood serum observed. Under the effect of 50 and 100 ppm there was no decrease in the tryptophane content of the liver and the blood serum. High concentrations of ammonia decreased the transamimase activity of the liver and heart and raised the activity of the serum GPT.
研究了不同浓度的氨气（5、20、50和100 ppm）对20日龄肉鸡作用120分钟后的影响。为研究肝脏、心肌和血清中的蛋白质含量以及游离氨基酸和色氨酸的含量，将鸡宰杀。还跟踪了肝脏和心肌的转氨酶活性以及谷草转氨酶（GOT）和谷丙转氨酶（GPT）的活性。结果表明，氨气不会改变被研究器官和血清中的蛋白质含量。观察到血清中游离氨基酸浓度可靠增加。在50和100 ppm氨气作用下，肝脏和血清中的色氨酸含量没有降低。高浓度氨气降低了肝脏和心脏的转氨酶活性，并提高了血清GPT的活性。
