Penelitian ini bertujuan untuk mengetahui efek penambahan undegraded protein pellet terhadap konsumsi dan kecernaan nutrien kambing perah laktasi. Undegraded protein pellet merupakan pakan suplemen sumber protein yang terproteksi dalam bentuk pellet untuk melindungi protein dari degradasi mikroba rumen, sehingga dapat meningkatkan jumlah protein yang masuk ke dalam intestinum. Penelitian dilakukan secara in vivo dengan 2 perlakuan dan 5 ulangan. Penelitian ini menggunakan 10 ekor induk kambing Peranakan Ettawa (PE) dengan periode laktasi ke-1 sampai ke-2, rata- rata bobot tubuh 46,8±5,6 kg, dan nilai body condition score (BCS) berkisar 2,75 sampai 3. Kambing dibagi menjadi 2 kelompok, yaitu kelompok kontrol (P0) (ransum basal tanpa penambahan undegraded protein pellet) dan kelompok perlakuan (P1) (ransum basal dengan penambahan 20% undegraded protein pellet dari sumber protein). Bahan pakan yang digunakan yaitu hijauan (tebon jagung dan kaliandra) dan konsentrat (Nufeed®, ampas tahu, dan pollard). Sampling pakan dilakukan satu kali sehari selama penelitian, koleksi feses dilakukan satu kali sehari selama 7 hari pada minggu ke empat selama penelitian. Variabel yang diamati komposisi kimia, konsumsi nutrien, dan kecernaan nutrien. Data yang diperoleh diantara dua kelompok perlakuan akan dianalisis dengan uji Independent Sampel T-test. Hasil penelitian menunjukkan bahwa konsumsi bahan kering (BK), bahan organik (BO), protein kasar (PK), acid detergent fiber (ADF), neutral detergent fiber (NDF), non-fiber carbhydrate (NFC), dan kecernaan PK (KcPK) antara kelompok P0 dengan kelompok P1 menunjukkan perbedaan (P<0,05). Namun, konsumsi lemak kasar (LK), kecernaan BK, BO, LK, NDF, ADF, dan NFC tidak menunjukkan perbedaan. Hasil penelitian ini dapat disimpulkan bahwa penambahan undegraded protein pellet pada ransum kambing perah laktasi dapat meningkatkan konsumsi BK, BO, PK, NDF, ADF, NFC, dan KcPK. Namun, tidak meningkatkan konsumsi LK, kecernaan BK, BO, LK, NDF, ADF, dan NFC.

The aim of this study to determine the effect of addition undegraded protein pellets on consumption and nutritional digestibility of lactating dairy goats. Undegraded protein pellet is a protein source supplement that is protected in the form of pellets to protect protein from degradation of rumen microbes, it can increase the amount of protein that enters the intestine. The study was conducted in vivo with 2 treatments and 5 replications. This study used 10 Ettawa Crossbreed (PE) goats with 1 to 2 lactation periods, 46,8±5,6 kg average body weight, and body condition score (BCS) ranging from 2.75 to 3. The goats were divided into 2 groups, the control group P0 (diet without the addition undegraded protein pellets) and the P1 group (diet with the addition 20% undegraded protein pellets from the protein source). The feed ingredients used are forage (corn stover and calliandra) and concentrates (Nufeed®, tofu waste, and pollard). Feed sampling was carried out once a day during the study, sampling was carried out once a day for 7 days in the fourth week of the study. The observed variables included chemical composition, nutrient consumption and digestibility. The data obtained from the two treatment groups will be analyzed by using the Independent Sample T-test. The results showed that the consumption of dry matter (DM), organic matter (OM), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), non-fiber carbhydrate (NFC), and CP digestibility between the control group and the treatment showed significant effect (P<0.05). However, the consumption of ether extract (EE), the digestibility of DM, OM, EE, ADF, NDF, and NFC showed not significant effect. The results of this study can be concluded that giving undegraded protein pellets to lactation dairy goat feed can increase consumption of DM, OM, CP, NDF, ADF, NFC, and CP digestibility. However, it does not increase EE consumption, DM, OM, EE, NDF, ADF, and NFC digestibility.
