The studies were carried out on the chickens given the diet containing 19% and 11% of protein. On the 7th day of their life one part of the chickens were infected with different doses (125-500) of invasive eggs of Ascaridia galli. The other part of the birds were infected with 500 eggs of A. galli and the invasion lasted from 5 to 49 days. In the extracts from pancreas the activities of trypsin and alpha-amylase were measured. No differences were observed between trypsin activity of control and infected chickens fed with diet containing 11% of protein. The activity of trypsin was lower in infected chickens fed with diet containing 19% of protein, when the invasion lasted over 15 days. The activity of alpha-amylase in both groups decreased after infection with more than 100 invasive eggs of A. galli. The intensity and the extensiveness of invasion were lower in the chickens given the diet of 19% of protein.
这些研究是在喂食含19%和11%蛋白质日粮的鸡身上进行的。在它们出生后的第7天，一部分鸡被感染了不同剂量（125 - 500个）的鸡蛔虫侵袭性虫卵。另一部分鸡被感染了500个鸡蛔虫卵，感染持续5至49天。测定了胰腺提取物中胰蛋白酶和α -淀粉酶的活性。在喂食含11%蛋白质日粮的对照组和感染组鸡之间，未观察到胰蛋白酶活性有差异。当感染持续超过15天时，喂食含19%蛋白质日粮的感染组鸡的胰蛋白酶活性较低。在用超过100个鸡蛔虫侵袭性虫卵感染后，两组中α -淀粉酶的活性均下降。喂食含19%蛋白质日粮的鸡的感染强度和范围较低。
