This study was conducted for five months, in CV. Susu Abadi, Tegal Regency, Central Java at the Animal Science Feed Stuff Laboratory, Faculty of Animal Science, Jenderal Soedirman University. In all, 16 Sapera goats (first lactation), with an average weight of 39.47 ± 3.80 kg, were studied and the feed given was 3.25% DM/kg BW. The research method was in vivo, using a completely randomized design, involving four treatments. The treatments tested were R0 as basal feed (70% forage + 30% concentrate), R1 (basal feed + rumensin 30 mg/kg DM), R2 (basal feed + 250 ppm garlic), and R3 (R2 + organic minerals; 0.3 ppm Se + 1.5 ppm Cr + 40 ppm Zn lysinate). The data obtained were analyzed, using analysis of variance and correlation analysis. The best value of nutrient utilization was seen for (R3) DMI/Milk Yield of 1.02 ± 0.22, (R2) OMI/Milk Yield of: 0.94 ± 0.13. (R2) OMI/Production of Total Solid: 7.23 ± 1.04, (R2) OMI/Production of Lactose: 25.26 ± 3.36, and (R2) OMI/Production of Casein: 29.93 ± 3.96. The best value of lactation performance was for (R3) 1210.26 ± 273.50 ml. The lowest Methane Production value was indicated by (R3) 1.11 ± 0.13. The highest correlation value was seen in the consumption of crude fiber and crude protein of milk fat production (R2 = 0.28). The digestibility values of CP and CF showed significant differences (P &lt; 0.05), while the digestibility values of DM and OM did not show any significant differences (P &gt; 0.0.5). The consumption values of DM, OM, CP, and CF had no significant differences (P &gt; 0.0.5) when observed in the experimental treatments. It can be concluded that the supplementation of 250 ppm garlic flour in goat feed lactation milk results in lower methane production than in the case of all other treatments that were tested. Supplementation of garlic flour and organic minerals (Cr, Se, and Zn) increase the efficiency of milk production, nutrient utilization, and lactation performance in dairy goats.</p&gt;}, number={1}, journal={Revista Electronica de Veterinaria}, author={Azwar, Fajar Daya Winasis and Munasik, Munasik and Prayitno, Caribu Hadi}, year={2023}, month={Mar.}, pages={42 - 53} }
