The effect of liquid tumeric extract supplementation on carcass production and chemical quality of broiler meat
The purpose of this research was to find out the effects of liquid turmeric extract (LTE) supplementation as a phytobiotic on carcass production and chemical quality of broiler chicken meat. The research is conducted with a directional pattern completely randomized design. Eighty-four broiler chickens were raised from day old (DOC) to 42 days old chick. From DOC to 14 days old chicks were fed with commercial feed (ME 3,100 kcal/kg; CP 22%; Ca 1%; P 0.75%). During 15-21 days of age given a commercial feed mixture and basal feed (ME 3,201.77 kcal/kg; CP 20.21%; Ca 0.90%; and P 0.43%). At 22-42 days old given treatments. Seven treatments were replicated 3 times consisted of 4 broiler chickens for each replication. The treatments were positive control (P1), negative control (P2), water + LTE 2% (P3), water + LTE 4% (P4), water + LTE 6% (P5), water + LTE 8% (P6), and water + LTE 10% (P7). The results showed that LTE 10% significantly decreased (P<0.05) on the slaughter weight and 8% until 10% dossage had a significant decrease (P<0.05) on the meat water content. However, it did not show a significant influence (P>0.05) on the carcass weight, carcass percentage, meat protein and fat content.
