Performance of crossbred calves with dietary supplementation of garlic extract

Twelve crossbred calves (Holstein cross) in their pre-ruminant stage were used to study the effect of garlic extract feeding on their performance and they were randomly allotted into treatment and control groups in equal number. Performance was evaluated by measuring average body weight (BW) gain, feed intake dry matter (DM); total digestible nutrient (TDN) and crude protein (CP)], feed conversion efficiency (DM, TDN and CP), fecal score and fecal coliform count. Diets were same for both groups. In addition, treatment group received garlic extract supplementation at 250 mg/kg BW/day/calf. BW measured weekly, feed intake measured twice daily, proximate analysis of feeds and fodders analysed weekly, fecal scores monitored daily and fecal coliform count done weekly. There was a significant (p < 0.01) increase in mean BW gain and feed intake and a significant (p < 0.01) decrease in severity of scours as measured by fecal score in the treatment group compared to the control group. The results suggest that garlic extract can be supplemented to the calves for better performance.
