ABSTRAK Penelitian ini bertujuan untuk menguji pengaruh suplementasi minyak ikan lemuru terproteksi dan L-carnitine dalam ransum terhadap kecernaan bahan kering dan bahan organic pada pakan sapi perah laktasi.. Penelitian menggunakan 12 ekor sapi perah betna berumur 3-4 tahun dengan bobot badan rata-rata 400 ±5 kg . Penelitian menggunakan bahan pakan yang terdiri atas rumput gajah dan ransum basal (jagung kuning, bekatul, bungkil kedele, bungkil kelapa, mineral)/ L-karnitin, minyak ikan

Perlakuan terdiri atas:45% jerami padi + 55% konsentrat; P1 = 15% jerami padi + 30% jerami padi fermentasi + 55% konsentrat; P2 = 15% jerami padi + 30% jerami padi fermentasi + 55% konsentrat + 1000 ppm L-carnitin; dan P3 = 15% jerami padi + 30% jerami padi fermentasi + 55% konsentrat + 1000 ppm L-carnitin + 4% minyak ikan lemuru terproteksi. Hasil analisis variansi menunjukkan bahwa suplementasi minyak ikan lemuru terproteksi dan L-carnitin dalam ransum yang menggunakan jerami padi fermentasi berpengaruh sangat nyata (P<0,01) terhadap nilai konsumsi bahan kering dan konsumsi bahan organik serta nilai kecernaan bahan kering dan kecernaan bahan organik..Kesimpulan yang di dapat yaitu suplementasi minyak ikan lemuru terproteksi dan L-Carnitin mampu menurunkan konsumsi bahan kering dan bahan organik serta meningkatkan nilai kecernaan bahan kering dan kecernaan bahan organik.

The materials used were 12 lactating dairy cows with average body weight 400 ± 5 kg. The study design was a randomized block design with 4 treatments and each treatment consisting of 3 blocks, each block contains one period of lactation dairy cows. Treatments were P0 = 45% rice straw + 55% concentrate; P1 = 15% rice straw + 30% fermented rice straw + 55% concentrate; P2 = 15% rice straw + 30% fermented rice straw + 55% concentrate + 1000 ppm L-carnitine; and P3 = 15% rice straw + 30% rice straw fermented rice straw + 55% concentrate + 1000 ppm L-carnitine + 4% protected lemuru fish oil. . The results of variance analysis showed that supplementation protected lemuru fish oil and Lcarnitine in the diet rice straw fermentation was high significantly increased (P <0.01) on dry matter intake, consumption as well as dry matter digestibility and digestibility of organic matter in lactating dairy cows. It could be concluded that supplementation protected lemuru fish oil and L-carnitine in the diet of rice straw fermented able to reduce the consumption of dry matter and organic matter and increase the value of dry matter and organic matter digestibility.
