In three experiments broiler chickens were inoculated with sporulated Eimeria acervulina oocysts at 18 d of age. Feed intake, body-weight gain, brush-border enzyme activities, fat digestion, protein digestion and protein retention were measured. Body-weight gain was reduced during the acute phase of the infection and increased during the recovery phase of the infection. Feed intake was decreased on day 4 and day 5 postinfection (PI) and increased from day 7 to day 11 PI. Maltase (EC 3.2.1.20) and sucrase (EC 3.2.1.48) activities were decreased on day 5 PI in all intestinal segments. In Expts 2 and 3, however, maltase activity was increased in the ileum. Fat digestion was decreased from day 2 to day 11 PI. N digestion and retention were decreased from day 2 to day 11 PI.
在三项实验中，18日龄的肉鸡接种了孢子化的堆型艾美耳球虫卵囊。测量了采食量、体重增加、刷状缘酶活性、脂肪消化、蛋白质消化和蛋白质潴留情况。感染急性期体重增加减少，感染恢复期体重增加增加。感染后第4天和第5天采食量下降，感染后第7天至第11天采食量增加。感染后第5天，所有肠段的麦芽糖酶（EC 3.2.1.20）和蔗糖酶（EC 3.2.1.48）活性均下降。然而，在实验2和3中，回肠中的麦芽糖酶活性增加。感染后第2天至第11天脂肪消化减少。感染后第2天至第11天氮消化和潴留减少。
