Modern poultry production relies on an ability to prevent and mitigate challenges to bird health, while maintaining a productive bird. A number of different classes of biologics-based feed additives exist, and many have been tested individually for their impacts on poultry health and performance. Fewer studies have examined the combinations of different classes of products. In this study, we examined the use of a well-established postbiotic feed additive (Original XPC, Diamond V) on turkey performance, with and without the addition of a proprietary saponin-based feed additive. This was accomplished in an 18-wk pen trial utilizing 22 pen replicates per treatment across 3 treatments (control, postbiotic, and postbiotic plus saponin). Significant differences in body weight were identified at wk 12 and 15 of age, with the postbiotic plus saponin treatment group resulting in heavier birds at both timepoints. Significant differences in feed conversion ratio were observed from 0 to 18 wk of age, with the postbiotic alone having improved FCR compared with the control group. No significant differences were observed for livability or feed intake. This study demonstrates that a combination of a postbiotic plus saponin may exert additive effects on the growth of the turkey.
现代家禽生产依赖于预防和减轻鸟类健康挑战的能力，同时保持禽类的生产性能。有许多不同类别的基于生物制品的饲料添加剂，其中许多已经单独测试了它们对家禽健康和性能的影响。较少的研究检查了不同类别产品的组合。在这项研究中，我们研究了使用一种成熟的后生元饲料添加剂（Original XPC，Diamond V）对火鸡生产性能的影响，同时添加和不添加专有的皂素基饲料添加剂。这是通过在 3 种处理（对照、后生元和后生元加皂素）中，每处理使用 22 个栏重复进行 18 周的栏试验来完成的。在 12 周和 15 周龄时，体重有显著差异，后生元和皂素处理组在这两个时间点的体重都更重。从 0 到 18 周龄时，饲料转化率有显著差异，单独使用后生元与对照组相比，FCR 得到改善。成活率和采食量没有显著差异。本研究表明，后生元和皂素的组合可能对火鸡的生长有相加作用。
