Abstract

This investigation evaluates the influence of Direct-Fed Microbials (DFM) on growth metrics, feed conversion efficiency, and economic parameters in Kankrej calves. Conducted at Gujarat’s Animal Nutrition Research Station over 98 days, the study involved 15 calves distributed into three groups, with two experimental groups receiving 2% and 3% DFM in their Total Mixed Ration (TMR). Biweekly assessments revealed a consistent yet non-significant trend towards increased weight in DFM-supplemented groups compared to controls. This pattern suggests a potential for DFM to positively affect growth over time. The DFM cohorts also demonstrated improved feed efficiency, with a marked reduction in Dry Matter Intake (DMI), indicative of enhanced nutrient assimilation and metabolic function. From an economic standpoint, DFM supplementation was associated with decreased feed costs and heightened feed efficiency, suggesting a cost-effective strategy for calf nutrition. Overall, the study provides evidence supporting the integration of DFM into calf-rearing practices, potentially contributing to more economically and environmentally sustainable livestock management

Conclusion

Our study demonstrates that direct-fed microbials (DFMs) at 2% and 3% concentrations significantly improve feed conversion efficiency and growth metrics in cattle calves, while also offering economic benefits through reduced feed costs. These findings suggest DFMs as a viable strategy for enhancing livestock productivity and profitability. Future research should further investigate the long-term effects of DFMs to solidify their role in sustainable cattle farming
