A study was conducted to evaluate the effect of Mentha piperita and Cymbopogon citratus essential oils on feed intake and nutrient digestibility in crossbred calves. 18 healthy calves aged 15 to 90 days, were randomly allotted to 3 treatment groups in a completely randomized design. The treatments included a control diet (T₀) and diets supplemented with M. piperita essential oil @ 0.2% of calf starter (T₁), C. citratus essential oil @ 0.2% of calf starter (T₂), Feed intake and digestibility coefficients of nutrients were determined through a digestion trial at the end of 90 days. Results indicated that supplementation with M. piperita and C. citratus essential oils significantly (P<0.01) improved digestibility percentage of dry matter compared to the control. No adverse effects were observed on palatability or health status of the calves. The findings suggest that M. piperita and C. citratus essential oils may serve as effective natural feed additives to enhance nutrient utilization efficiency in crossbred calves.

In conclusion, supplementation with MPEO and CCEO at 0.2% inclusion levels showed no adverse effect on feed intake, indicating good palatability and tolerance in crossbred calves. The improved dry matter digestibility suggests enhanced rumen fermentation efficiency and microbial activity, contributing to better nutrient utilization and overall feed efficiency.
