摘要

饲料通过综合征(FPS)是一种常见的疾病,包括排泄物潮湿、饲料未消化和饲料效率下降,涉及多种诱发因素。正在研究抗微生物药物的替代品,包括植物源性药物,以控制这一过程。本研究旨在评估在自然场FPS攻击下肉鸡的牛至精油(OEO)。四个出现FPS的肉鸡舍(两个雄性;两个雌性)被分为两组,每组并通过饮用水分配到对照组或OEO处理组,为期五天。FPS的特征在于>;30%的湿粪便,>;50%与未消化的饲料,<;5%的粘膜脱落,>;10%的鸟类患有肠炎,90%的鸟类患有回肠下部未消化的饲料,以及临床上呈菌群失调阳性的鸟类。经过五天的治疗,OEO治疗的鸟类表现出更少的异常粪便(P<;0.05),降低了菌群失调的患病率(P=0.0404),体重逐渐恢复。OEO治疗显示出对Gompertz生长曲线参数的影响(生长率,P=0.0165;拐点,P=0.0359),在0.8天内潜在地降低目标市场重量下的年龄。总之,研究结果表明,在饮用水中对患有饲料通道综合征的肉鸡进行OEO处理可以改善排泄物特性,并减轻该综合征对体重的负面影响。

The effect of oregano essential oil on Feed Passage Syndrome in broilers: 1. Assessment under field conditions

Feed Passage Syndrome (FPS) is a prevalent condition that includes wet excreta, with undigested feed, and loss of feed efficiency, with multiple predisposing factors involved. Alternatives to antimicrobials, including phytogenics, are being studied to control this process. This study aimed to assess oregano essential oil (OEO) in broilers subjected to a natural field FPS challenge. Four broiler houses (two males; two females) presenting FPS were divided into two groups per house and assigned to a control or OEO-treated group through drinking water for five days. The FPS was characterized by >30% wet droppings, >50% with undigested feed, <5% with desquamated mucosa, >10% birds with enteritis, and 90% with undigested feed in the lower ileum, and flocks clinically positive for dysbacteriosis. After a five-day treatment, OEO-treated birds showed fewer abnormal droppings (P < 0.05), reduced the prevalence of dysbacteriosis (P = 0.0404), and a progressively recovering BW. The OEO treatment showed to influence the Gompertz growth curve parameters (growth rate, P = 0.0165; inflection point, P = 0.0359), potentially reducing the age at the target market weight in 0.8 days. In conclusion, the results indicate that the OEO treatment in drinking water for broilers naturally challenged with the Feed Passage Syndrome may improve excreta characteristics and attenuate the negative impact of the syndrome on the BW.
