Abstract: This research aimed to determine the effect of adding garlic peel antioxidant supplementation and organic minerals to rations prepared with an RDP: RUP ratio of 60:40, on digestibility, rumen fermentation characteristics, microbial protein synthesis, protozoa population, and methane gas production.This research used an in vitro method, which used goat rumen fluid, with a completely randomized design with 4 treatments and 4 replications.Treatment consisted of P0=no supplementation; P1=3% organic mineral supplementation; P2=Supplementation 3% garlic peel; P4=Supplementation 1.5% organic minerals + 1.5% garlic peel.The results show that feed supplementation using garlic peel antioxidants and organic minerals significantly affects (P<0.05) on dry matter digestibility, organic matter digestibility, crude fiber digestibility, and crude fat digestibility.However, there was no significant (P>0.05)effect on pH values, VFA and NH3 concentrations.Furthermore, has a real effect on reducing protozoa populations and methane gas.This research concluded that rations with the addition of 3% garlic peel antioxidant supplementation and the addition of 1.5% garlic peel supplementation and 1.5% organic minerals can improve rumen fermentation characteristics and nutrient digestibility.However, further research needs to be done on in vivo methods directly on livestock.
