Abstract

Mild infections of Eimeria maxima, E. acervulina, E. mivati, E. brunetti, E. necatrix, or E. tenella that did not affect weight gain significantly (P greater than .05) caused significant (P less than .05) shank depigmentation in 6-week-old broilers fed a broiler diet. Infections of E. maxima, E. mivati, or E. acervulina caused numerically more depigmentation than did infections by E. tenella, E. brunetti, or E. necatrix. Significant depigmentation was first detected at 4 days postinoculation (pi) with some species, prior to other gross evidence of infection, and infected birds regained little lost pigment by 14 days pi. Pigmentation among the infections by different species from the time of innoculation to 14 days pi was not significantly different (P greater than .05) amongst the treatments.

摘要

对饲喂肉鸡日粮的6周龄肉鸡而言，感染巨型艾美耳球虫、堆型艾美耳球虫、米氏艾美耳球虫、布氏艾美耳球虫、毒害艾美耳球虫或柔嫩艾美耳球虫后，若体重增加未受到显著影响（P＞0.05），则会导致明显的（P＜0.05）胫部色素脱失。巨型艾美耳球虫、米氏艾美耳球虫或堆型艾美耳球虫感染所致的色素脱失在数量上比毒害艾美耳球虫、布氏艾美耳球虫或柔嫩艾美耳球虫感染更多。在接种后4天（pi），部分虫种首次检测到明显的色素脱失，此时尚无其他明显的感染迹象，且感染鸡只在接种后14天色素损失几乎未恢复。在各处理组中，从接种到接种后14天，不同虫种感染后的色素沉着无显著差异（P＞0.05）。
