摘要
To study the effect of dietary supplementation of Problend, (a mixture of probiotics, enzymes and yeast) on the growth performance and economics of production;160 (3 wk) Vanaraja chicks were randomly distributed into 4 equal groups and fed on a standard diet supplemented with 200, 300 or 400 mg Problend kg(-1) diet. The body weight gain and feed conversion ratio improved (p<0.01) by supplementation of 400 mg per kg Problend. The retentions of dry matter, protein and fat increased (P<0.01) with Problend supplementation. However, the cost of meat production increased only at the highest level. It is concluded that 400 mg problend per kg diet improved performance and economics of production of Vanaraja chickens.
