The Role Of Direct-Fed Microbials In Livestock Production

Supplementation directly fed microbial (DFM) as a means to improve the health and performance of livestock has been generating significant interest over the last 15+ years. 

The great interest in DFM is to eliminate or decrease the use of low-dose antibiotics in livestock production. This increased attention to direct fed microbial resources has produced a vast body of research.

These efforts have resulted in conflicting reports. Although there have been variations in the design of this study, one of the main causes of the lack of consistency may be due to variations in experimental immune challenges included to evaluate DFM supplementation. 

Noting the experimental immunity challenge, there is strong evidence to suggest that supplementation DFM may have an impact on the immune response, overall health, and performance of livestock

Recent years have seen a significant increase in marketing direct fed microbials (DFMs) for all sectors of livestock farming (cattle, pigs and poultry). The main reason for this expansion in DFMs is to substitute low-dose antibiotics (LDAs).

Use of LDAs to improve animal health in agriculture, animal husbandry has become a common practice for more than 30 years. LDAs are used to improve the overall health of livestock. This enhanced health benefit is an increase in body weight (BW) and increased feed efficiency.
