Abstract

The experiment was conducted to investigate the effect of transfer of PUFA protected and carnitin precursor on the ration of chemical composition of milk dairy goat. In total, 10 female dairy goats of 2 - 4 years old Peranakan Etawah (PE) with body weight of 25 - 45 kg were used in this experiment. The feed material included a basal diet (control) based on yellow corn, rice bran, soya bean meal, coconut meal, tuna fish oil and lemuru fish oil. The method of the research was experimental in vivo using Randomized Completely Block Design (RCBD). There were 5 treatments in each experiment and 2 replications. The treatment consisted of P₀ = control ration, P₁ = P₀ + 200 ppm L-carnitine on the ration, P₂ = P₁ + soya bean oil, P₃ = P₁ + protected tuna fish oil 5 ml or equal with 4% in the ration, and P₄ = P₁ + protected lemuru fish oil 5 ml or equal with 4% in the ration. The measured variable is chemical composition of milk dairy goat. The results of variance analysis showed that the effect of transfer of PUFA fatty acid in the rations contained 200 ppm L-carnitine significantly (P < 0.01) affecting the chemical composition of milk dairy goat. This research concluded that the transfer of PUFA fatty acid protected in the ration containing 200 ppm L-carnitine can decrease milk cholesterol from 0.19% to 0.12%, LDL from 33.34 to 23.13 mg/dl, lipid from 4.53% to 3.76% then to increase omega-3 fatty acid from 1.00% to 3.94%, omega-6 fatty acid from 1.46% to 18.80%.
