Experiment (TN) was conducted to evaluate the effect of turmeric supplementation (after curcumin extraction) at 2 different levels on meat production and jaundice of JA-DABACO chickens. The experiment was divided into 3 groups of 30 heads each. The control group (DC) only uses complete mixed foods according to age stages. Lot TN1 has turmeric supplement at 3%. Lot TN2 added turmeric extract at 5%. The results showed that the addition of turmeric in the diet increased the survival rate (the control lot was 94.73%, that of TN1 was 99.78% and that of TN2 was 99.88%. ), increase in body weight (body weight of chickens at 10 weeks of age in the control group, batch of TN1 and batch of TN2 are 1173,3
1273,3 and 1356,72g / head respectively), while increasing color The color of chicken skin was significantly (from 2.67 in the control lot to 3.2 and 3.9 Roche units in batch TN1, 2). The results of this study open up the potential of using turmeric extracted from curcumin extraction in chicken diets to increase growth rate, as well as improve the color of chicken skin.Thí nghiệm (TN) được tiến hành để đánh giá ảnh hưởng của việc bổ sung bã nghệ (sau tách chiết curcumin) ở 2 mức khác nhau đến sức sản xuất thịt và độ vàng da của gà JA-DABACO.
