This study compared a novel non-formaldehyde combination product developed for pathogen control in animal feed Finio (A), with a panel of three commonly used organic acid feed additive products: Fysal (B), SalCURB K2 (C) and Salgard (D). Products were evaluated for their ability to reduce Typhimurium DT104 and avian pathogenic in poultry feed. A commercial layer-hen mash was treated with each product and then mixed with feed previously contaminated (via inoculated meat and bone meal) with either or After 24 hours at room temperature, 10 replicate samples were taken from each preparation and plate counts were performed using a selective agar. All concentrations of product A (0.5, 1.0, 1.5, 2.0 and 2.5 kg per metric tonne (MT)) plus the higher concentration of products B and D (6.0 kg MT) significantly reduced counts compared with those in the untreated control group ( < 0.05). Product C did not significantly reduce levels of under these conditions. Because of the poor recovery of , statistical comparisons for this organism were limited in scope, but only product A at the highest concentration appeared to have eliminated it.
本研究将一种为控制动物饲料中的病原体而开发的新型无甲醛复合产品Finio(A)与一组三种常用的有机酸饲料添加剂产品进行了比较:Fysal(B)、SalCURB K2(C)和Salgard(D)。评估了这些产品在降低家禽饲料中鼠伤寒沙门氏菌DT104和禽致病性方面的能力。用每种产品处理一种商品蛋鸡混合料,然后与先前(通过接种肉骨粉)被[具体病原体1]或[具体病原体2]污染的饲料混合。在室温下放置24小时后,从每种制剂中取10个重复样品,并使用选择性琼脂进行平板计数。与未处理的对照组相比,产品A的所有浓度(每公吨0.5、1.0、1.5、2.0和2.5千克)以及产品B和D的较高浓度(6.0千克/公吨)均显著降低了[具体病原体1]的计数(P<0.05)。在这些条件下,产品C没有显著降低[具体病原体1]的水平。由于[具体病原体2]的回收率较低,对该病原体的统计比较范围有限,但只有最高浓度的产品A似乎消除了它。
