Coccidiosis is the major parasitic disease of poultry. In this study, the role of the commercial probiotic MitoMax which contains Pediococcus acidilactici and Saccharomyces boulardii was evaluated by measuring body weight gain, fecal oocyst shedding, and serum antibody responses as an alternative control method of prophylactic drug against coccidiosis. Day-old broiler chicks were fed regular or probiotic diets supplemented with MitoMax at 0.01%, 0.1%, or 1.0% of diet, and challenged 2 weeks later with 5000 oocysts of either Eimeria acervulina (EA) or Eimeria tenella (ET). Birds fed 1.0% or 0.1% MitoMax-supplemented diets in EA- or ET-infected groups shed less (P<0.05) oocysts than control-infected chickens. Also, chickens fed 0.1% MitoMax-supplemented diet and infected with EA exhibited higher (P<0.001) serum Eimeria-specific antibodies than other groups. These results demonstrate that MitoMax may enhance the resistance of birds against coccidiosis by enhancing humoral immunity when included at > or = 0.1% of the broiler diet.
球虫病是家禽的主要寄生虫病。在本研究中,通过测量体重增加、粪便卵囊排出量和血清抗体反应,评估了含有嗜酸乳杆菌和布拉酵母菌的商业益生菌MitoMax作为预防球虫病的预防性药物替代控制方法的作用。将1日龄的肉鸡雏鸡饲喂添加0.01%、0.1%或1.0% MitoMax的常规或益生菌日粮,2周后用5000个堆型艾美耳球虫(EA)或柔嫩艾美耳球虫(ET)卵囊进行攻毒。在EA或ET感染组中,饲喂添加1.0%或0.1% MitoMax日粮的鸡比未感染的对照鸡排出的卵囊更少(P<0.05)。此外,饲喂添加0.1% MitoMax日粮并感染EA的鸡比其他组表现出更高(P<0.001)的血清艾美耳球虫特异性抗体。这些结果表明,当MitoMax在肉鸡日粮中的添加量≥0.1%时,可能通过增强体液免疫来提高鸡对球虫病的抵抗力。
