Implementation of Microcapsules of Noni Fruit Extract (Morinda citrifolia L) as a Feed Additive on Nutritional Digestibility and Performance of Sentul Chickens

Abstract

The continuous use of growth promoter (AGP) antibiotics in rearing chickens will cause residues in the meat. Finding a natural antibiotic derived from herbal plants that noni fruit is necessary. Microencapsulation of noni fruit extract (MNFE) was reported to positively affect poultry nutrition absorption. The research was conducted to determine the effect of MNFE with maltodextrin and its implementation as a feed additive to nutrient digestibility and the performance of Sentul chicken. The experiment used 100 Sentul chicks with a Completely Randomized Design (CRD), with five treatments and four replications. The treatment consisted of basal ration T0 (control), T1 (basal ration + 50 mg/kg Zinc-Bacitracin), T2 (basal ration + 125 mg/kg MNFE), T3 (basal ration + 125 mg/kg MNFE), and T4 (basal ration + 375 mg/kg MNFE). Variables observed were nutrient digestibility (crude protein digestibility, dry matter digestibility, organic matter digestibility, metabolic energy, nitrogen retention) and performance (feed consumption, body weight gain, feed efficiency). The results showed that Crude Protein Digestibility (CPD), Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), metabolic energy, nitrogen retention, and performance of Sentul chicken were significantly (p<0.05) different in the group when compared to controls. It was concluded that adding 250 mg/kg MNFE could improve Sentul chicken's best nutrient digestibility and growth performance. It is recommended to be used as a feed additive to replace AGP.
