The experiment was conducted at The Experimental Station of Tra Vinh University from August to October 2014 on 270 quail from 11-39 days of age to evaluate the effects of the additional premix in diets on the growth of quail meat. The experiment was designed completely random with 3 treatments and 3 repetitions: Treatment control: basal diet of farm; treatment ML: basal diet plus 1 kg premix ML/200 kg feed and treatment Plastin: basal diet plus 1 kg premix Plastin/300 kg feed. The results showed that additional premix ML in quail diet was highest weight gain and carcass ratio. Because the ingredients ML vitamin supplementation increases the resistance and nutrient absorption. Feed intake was no statistical significance (P0.05). However, feed conversion ratio is lowest in treatment ML (3.45), followed by Plastin (3.62) and the control (3.83) with P=0.03. It is suggested that pemix ML could be used in quail diets without any deleterious effects on the birds.
