Brown beef cattle

BOVAMINE® Defend

Performance

From a summary of 14 trials conducted on commercial cattle feed lots in the US, cattle fed BOVAMINE® Defend yielded heavier carcasses, had better average daily gains, and tended to have better feed-to-gain conversions (see Figures 1a and 1b below).

Reduced shedding of pathogenic E. coli

Across 15 studies, cattle fed BOVAMINE® Defend were 45% less likely to shed E. coli O157:H7 in their manure compared to control animals – a significant reduction in prevalence (see Figure 2a). More importantly, among the fewer cattle that were shedding E. coli O157, there was a >90% reduction in the concentration of that pathogenic organism in their manure compared to samples from control animals – a significant reduction in concentration (see Figure 2b).

Reduced shedding of pathogenic Salmonella

In a well-controlled study, cattle fed BOVAMINE® Defend were 48% less likely (p<0.10) than control animals to shed salmonella in their feces. Likewise, salmonella was 68% less likely (p<0.10) to be shed in the feces or isolated the hides of cattle fed BOVAMINE® Defend compared to control animals. Not only was there a reduced shedding of Salmonella, but the incidence of animals that had peripheral lymph nodes that were positive for Salmonella was also significantly reduced in the field and in a well-controlled trial (see Figures 3, 4 and 5). This reduces the risk of contamination of ground beef with this food-borne pathogen.
