Penelitian ini bertujuan untuk mengetahui pengaruh penambahan pakan sumber protein terhadap konsumsi dan kecernaan nutrien kambing kacang betina. Penelitian dilaksanakan di Kelompok Wanita Tani Gama Sumber Rejeki Wonolagi, Ngleri, Playen, Gunungkidul. Penelitian menggunakan 8 ekor kambing kacang betina umur 2 � 3 tahun dengan berat badan rata-rata 22 kg. Perlakuan terbagi atas 2 kelompok (Po dan Ko), masing-masing kelompok terdiri atas 4 ekor ternak. Perlakuan Po adalah pemberian hijauan secara ad libitum dengan penambahan pakan sumber protein. Perlakuan Ko adalah pemberian pakan hijauan secara ad libitum tanpa penambahan pakan sumber protein. Fokus penelitian pada pengamatan konsumsi dan kecernaan kambing kacang betina menggunakan metode in vivo. Perlakuan pakan berlangsung selama 3 bulan termasuk total koleksi selama 17 hari. Desain penelitian menggunakan Independent T-test. Hasil penelitian menunjukkan pemberian pakan sumber protein dapat meningkatkan konsumsi bahan kering (BK), bahan organik (BO), protein kasar (PK), lemak kasar (LK), bahan esktrak tanpa nitrogen (BETN), dan total digestible nutrient (TDN) (P<0,001). Konsumsi nutrien BK, PK, dan TDN perlakuan Po masing-masing adalah 44,12±6,86; 5,74±0,86 dan 27,55±4,38 g/kg/BB0,75/hari. Konsumsi nutrien BK, PK, dan TDN perlakuan Ko masing-masing adalah 34,87±2,71; 2,15±0,13 dan 20,59±3,08 g/kg/BB0,75/hari. Hasil penelitian penambahan pakan tambahan sumber protein meningkatkan koefisien cerna PK dan LK (P<0,001). Koefisien cerna BK, PK, dan TDN perlakuan Po masing�masing adalah 59,11±12,5; 86,21±4,48 dan 58,56±12,35%. Koefisien cerna BK, PK, dan TDN perlakuan Ko masing-masing adalah 68,71±3,75; 80,90±2,66 dan 68,21±4,61%. Berdasarkan hasil penelitian penambahan pakan sumber protein pada kambing kacang betina dapat meningkatkan konsumsi nutrien dan meningkatkan koefisien cerna protein kasar.

This study aimed to determine the effect of the addition concentrate feed protein to the consumption and digestibility nutrient of female Kacang goat. The research was conducted in Kelompok Wanita Tani Gama Sumber Rejeki Wonolagi, Ngleri, Playen, Gunungkidul. The study used 8 female Kacang goats aged 2 - 3 years with an average weight of 22 kg. Treatment was divided into 2 groups (Po and Ko), each group consists of 4 goats. Po treatment was fed forage ad libitum with the addition of concentrate feed protein. Ko treatment was fed forage ad libitum without addition of concentrate feed protein. This study focused on the observation of consumption and digestibility nutrient of female Kacang goats using in vivo method. The treatment of feed was done for 3 months including 14 days total collection. The research was designed using a independent T-test. The results showed that feeding concentrate feed protein increased the consumption of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), nitrogen free extract (NFE), and total digestible nutrient (TDN) (P<0.001). Consumption of DM, CP, and TDN of Po treatment were 44.12±6.86; 5.74±0.86 and 27.55±4.38 g/kg/BB0,75/day, respectively. Consumption of DM, CP, and TDN Ko of treatment were 34.87±2.71; 2.15±0.13 dan 20.59±3.08 g/kg/BB0,75/day, respectively. The results of the study that additional concentrate feed protein increased the coefficient of digestibility CP and EE (P<0.001). The coefficients of digestibility of DM, CP, and TDN of Po treatment were 59.11±12.5; 86.21±4.48 and 58.56±12.35%. The coefficient of digestibility of DM, CP, and TDN of Ko treatment were 68.71±3.75; 80.90±2.66 and 68.21±4.61%. Based on the results of the study the addition of concentrate feed protein in female Kacang goats can increase nutrient consumption and increase the coefficient of crude protein digestibility.
