Abstract :
The study was conducted to find the effect of tamarind kernel powder (TKP) as a prebiotics and lactobacillus reuteri as a probiotics on productive performance,carcas percentage and percentage of abdominal fat on broilers. The observed parameters of this study are productive performance (feed intake,average daily gain,mortality,and feed conversion ratio) carcass percentage and percentage of abdominal fat. 360 Arbor acres broilers were used (10 days of age), the experimental design was used completely randomized design (CRD) factorial, divided into 4 treatment combination and two factors with 5 replications each treatment. There are 20 experiment with both factors as control,the 2nd treatment is treatment is supplemented with 106 CFU/g of probiotics in the feed intake, the 3rd treatment are supplement with 3% of TKP in the feed intake, the 4th treatment is supplemented with 3% of TKP and 106 CFU/g probiotics in the feed intake. The result revealed that the supplement with probiotics are significantly increasing the growth of chickens (P<0.05) in the 106 CFU/g levels, the others observation parameters had no significant effect those levels. Prebiotics had no significant effect on the performance parameters also carcass percentage and percentage of abdominal fat (P<0.05) in the levels 3% of tamarind kernel powder.
