Background: Antibiotic Growth Promoter (AGP) as a growth
promoter has been banned in Indonesia since 2017. This has prompted the search
for alternative antibiotics to support poultry products' health, productivity,
and safety. This makes probiotics, prebiotics, and synbiotics potential
alternatives to replace AGP.
Aim of the Study: This study aims to test the effect of
adding encapsulated dahlia tuber extract as a prebiotic and Bacillus subtilis as a probiotic on
blood lipid profiles and live weight of broiler chicken.
Methodology: The research was conducted from October to
December 2023, at the Poultry Cage and the Laboratory of Nutrition and Feed
Science, Faculty of Animal and Agricultural Sciences, Diponegoro University,
Semarang, Indonesia. In this investigation, 200 unsexed Ross strain broilers
aged 8 days with an average body weight of 194.53 ± 3.46 g were used. The
treatment feed was administered at the age of 8-35 days, containing
encapsulated dahlia tuber extract as a prebiotic and Bacillus subtilis as a probiotic (EDTEBs). Dahlia tuber extract and
Bacillus subtilis were mixed in a
50:50 ratio. The study used a completely randomised design (CRD) with 4
treatments and 5 replications, each consisting of 10 broilers. The treatment
given was T0: basal ration, T1: basal ration + 0.1% EDTEBs, T2: basal ration +
0.2% EDTEBs, T3: basal ration + 0.3% EDTEBs. The parameters measured were blood
cholesterol, triglyceride, high-density lipoprotein (HDL), low-density
lipoprotein (LDL) levels, and live weight. Data were analysed using the JASP
program.
Results: The results showed that the addition of dahlia
tuber extract encapsulation and Bacillus
subtilis encapsulation had a significant effect on cholesterol levels (P
< 0.001), triglycerides (P<0.001), HDL (P = 0.002), LDL (P = 0.001), and
live weight (P < 0.001) in broilers. The addition of EDTEBs at a
concentration of 0.1% yielded optimal results in reducing cholesterol,
triglycerides, and LDL levels, while also increasing HDL levels and live weight
in broilers.
Conclusion: The effectiveness of the combination of Dahlia
tuber extract and Bacillus subtilis can
be reduced in the digestive tract, as the bioactive compounds and probiotic
bacteria may be damaged by acidic gastrointestinal conditions. The addition of
encapsulated dahlia tuber extract and Bacillus
subtilis at a 0.1% level improved the blood lipid profile of broiler
chickens by reducing cholesterol, triglyceride, and LDL levels while increasing
HDL levels and live weight. The best results were obtained in the 3% addition
treatment.
