The objective of the current study was to evaluate the effects of garlic extract (GE) supplementation on growth performance, nutrient digestibility, carcass characteristics and meat composition in broilers. Dietary treatment were control (corn-soy based diet, 0 ppm), and diets added with 100 or 200 ppm GE. Starter and finisher diets were fed from 0 to 3 wk and 4 to 5 wk, respectively. Supplementation of GE had no effect on weight gain, but there was trend towards improvement in growth rate in birds fed diets containing 100 ppm GE during overall period, while birds fed 100 ppm GE had better feed efficiency (p less than 0.05) than birds fed control diet during finisher period. Birds fed GE had greater (p less than 0.05) nutrient digestibility of dry matter than birds fed control diet. The TBARS values of breast muscle obtained from birds fed 100 and 200 ppm GE were lower than breast muscle of control birds on day 8 and 12 of storage. The breast muscle of birds fed 200 ppm GE had higher (p less than 0.05) L* values than breast muscle of birds fed control and 100 ppm GE diets. The carcass characteristics, meat and bone composition, CIE a* and b* values did not differ among the dietary treatments. In conclusion, supplementation of GE enhanced feed efficiency and nutrient digestibility in broilers.
