The influence of Phyllanthus niruri L. powder and Zn-bacitracin antibiotics on the relative weight of carcasses and intestines of broiler

Abstract

Phyllanthus niruri L (meniran) is included in Euphorbiaceae which is easy to grow in various geographies and has active compounds such as terpenoids, alkaloids, flavonoids, saponins, tannins, and phyllanthin. The purpose of this study was to evaluate the administration of Phyllanthus niruri L powder to the relative carcass weight, upper thighs, lower thighs, back, breast, wings and weights and the relative length of the intestine, duodenum, jejunum, and ileum of broiler chickens. The study used a Completely Randomized Design with 5 treatments, 4 replications, each replication consisted of 10 DOC with the following treatments: T1 (without antibiotics and P. niruri L powder (Control); T2 (Zn-bacitracin 0.05%) ; T3 (Phylanthus niruri L. powder 0.0157%); T4 (Phylanthus niruri L. powder 0.0313%); T5 (Phylanthus niruri L. powder 0.0470%). The results showed that life weight and relative weight of carcass, back, breast, upper thighs, lower thighs, wings, back, head + neck, legs, and abdominal fat were not significantly different (P>0.05) between treatments T1, T2, T3, T4, and T5. But the real breast relative weight (P<0.05) was higher in the T5 treatment compared to T2, T3, and T4. Likewise, the relative weight and length of the small intestine, duodenum, jejunum, and ileum were not significant (P>0.05) between all treatments. It was concluded that the treatment of P. niruri L. powder up to 0.0470% was not significant with the Zn-bacitracin treatment on live weight and relative weight of carcass , back, breast, upper thighs, lower thighs, wings, back, hackle + neck, legs, and abdominal fat. Also the relative weight and length of the small intestine, duodenum, jejunum, and ileum. Except for the P. niruri L. powder 0.0470% treatment that the relative weight of the breast was significantly higher than the Zn-bacitracin treatment, P. niruri L. powder 0.0157% and 0.0131%.
