So, combining postbiotics and other essential oil compound feed ingredients could have complementing modes of action delivering improved benefits in animals. EVALUATION OF DIA-V™ MBPRO IN BROILERS Dia-V™ MBPRO was developed with a unique combination of the postbiotic Saccharomyces cerevisiae fermentation product and a proprietary blend of seven different essential oil compounds. Four independent research trials were conducted in broilers to evaluate the benefits of Dia-V™ MBPRO with respect to performance and gut health. There were two treatments in each study, control (CON) or test (MBP), both receiving the same basal diet, with the latter receiving the on-top inclusion of 0.4kg/MT of Dia-V™ MBPRO (Diamond V Mills, Cedar Rapids, IA). All trials used commercial broiler strains with study designs containing 16 to 28 replicates/ treatment with 384 to 1440 birds/treatment. The birds were grown to 35/42d of age. Body weight, feed conversion ratio, and breast meat yield were collected from these birds. In addition to that, gut microbiome samples were collected and analyzed using Galleon™. Data were analyzed across the four trials to determine the overall benefits of this feed ingredient and the potential mode/s of action. PERFORMANCE BENEFITS OF UNIQUE FEED INGREDIENT COMBINATION IN BROILERS Body weight and feed conversion ratio of the birds fed basal diet with or without Dia-V™ MBPRO are shown in Figure 1 and 2. Overall, Dia-V™ MBPRO supported improved performance in broilers. Dia-V™ MBPRO fed birds had numerically (P>0.05) better body weight and feed conversion ratio at 35d. By 42d, the birds receiving Dia-V™ MBPRO had higher (P<0.05) magnitude of benefits in performance resulting in a significant improvement in body weight (2.45%) and feed conversion ratio (3.9 points) compared to control birds. In addition to that, there was numerical (P=0.1038) improvement in breast meat yield in Dia-V™ MBPRO (31.43%) birds compared to control (31.10%). GUT MICROBIOME MODULATION BY DIA-V™ MBPRO Cloacal samples were collected from these birds at 35 and 42d of age. The samples were analyzed Figure 1.
