Abstract

A study was carried out to determine the effect of Moringa oleifera powder (MO) and Guava leaves powder (GU) supplementations in diets on growth performances and carcass quality of local chicken (Tre). A total of 360 Tre chickens at the 4 weeks of age were randomly distributed in a completely randomized design experiment, with 3 treatments and 4 replicates (2 male and 2 female pens), each replicate consisted of a pen with 30 chickens/pen, the experimental data was collected during 10 weeks. Treatments used: (1) Control (Cont): Basal diet (B) without any supplementation; (2) MOP: B + 2% MO in the diet; (3) GUP: B+ 2% GU in the diet. The results showed the use of MOP had significant higher (p0.05). All treatments did not affect the carcass yield of the birds, but little improvement of yellow (b) color of breast (b=9.84) and thigh (b=9.61) meat of chickens in MOP compared to that in control group (b=8.32 (breast) and b =9.40 (thigh). The EE content of breast and thigh meat also reduced in MOP (0.65% and 2.94%) and GUP (0.68 %and 3.00%) compare with Cont group (0.75% and 3.11%), respectively. In general, adding Moringa oleifera and Guava leaf powders at the level of 2% in the diets could be better for improving ADG and FCR compare with control group; and increased yellow color but not with EE content of breast and thigh meat of Tre chickens.
