Cholesterol and Malondialdehyde Contents of Broiler-Chicken Meat Supplemented with Indigofera zolingeriana Top Leaf Meal
Abstract: This research aimed
to increase functional value of broiler-chicken meat containing high
antioxidant and low cholesterol through substitution of soybean meal (SBM) with
Indigofera zollingeriana top leaf meal (ILM). The experiment used 160 day old
broiler chicken (Cobb strain). The experimental chicken were provided dietary
treatments when they were 15-days old (initial body weight of 460.5±1.56
g/bird) and terminated on day 35. A completely randomized design (CRD) with
four treatments and four replications and ten birds in each replication was
used in this experiment. Dietary treatments were: R1= diet containing 20%
soybean meal (SBM) without I. zollingeriana top leaf meal (ILM); R2= diet containing
16% SBM and 5.9% ILM; R3= diet containing 12% SBM and 11.8% ILM; R4= diet
containing 8% SBM and 17.74% ILM. Variables measured were performances (feed
consumption, body weight gain, and feed conversion) and the quality of broiler
meat (cholesterol, fat content, and malondialdehyde [MDA] concentration). The
results showed that supplementation of 17.74%
ILM (R4) as the substitution of 60% soybean meal protein produced the
same performances of broilers as those of control diet (R1). Supplementation of
11.8% ILM as the substitution of 40% soybean meal protein (R3) decreased meat
cholesterol by 34.70%, meat fat content by 52.93%, and MDA concentration by
62.52%. The conclusion of this study was that supplementation of 17.74% ILM
produced the same performances as that of control diet, increased antioxidant
content of the meat, indicated by a lower MDA concentration, and decreased
cholesterol, as well as fat content of broiler-chicken meat.
