A total of 333 Mia x Luong Phuong roosters were randomlyassigned to 3 lots: control without supplementation, experiments 1 and 2 supplemented with 10 and20mg of product/1kg of feed, respectively. Experiments were carried out from 1 week to 12 weeksof age.

body weightsat 12 weeks of age, respectively 18.30 and 19.90%
reduced in FCR by 0.13 and 0.27kg, respectively.Supplementing JKN product at 20 mg/kg of feed level achieved the highest efficiency in terms ofFCR, reduced the rate of processed dehydration in thigh meat and increased the yellow color ofbreast meat.
