Abstract
The results showed that 0.5% phytase enzyme supplementation did not affect the production performance significantly (P>0.05) resulted to the lowest cholesterol, triglyceride, Economic Loss Index values and the best Product Index value. For experiment 2, the effect of the level of probiotic supplementation with Bacillus sp. on the performance and cost of small and medium-sized grower-finisher pigs were used 3 small crossbred breeds of pigs with 36 fattening periods. The different pigs as in the first experiment revealed their initial average weight was 58 kilograms. The results showed that 1.0% supplementation with probiotics did not significantly affect the production performance (P>0.05) to produce pork with the greatest tenderness and juiciness, product index, economic loss index, and saleable head return. In addition, the return of investment was significantly better for the 1% supplementation group than both in the control group and the 0.5% supplementation group (P <0.05)
