ABSTRAK Penelitian ini bertujuan untuk mengekplorasi karakteristik fisik dan hubungan antara karakteristik fisik feses dengan kecernaan pakan pada kambing perah Peranakan Etawah (PE). Enam belas ekor kambing PE laktasi 2 dan periode laktasi bulan 4-5 digunakan sebagai materi penelitian, dengan rancangan acak kelompok berdasarkan produksi susu sebagai ulangan. Ransum yang diberikan mengandung protein kasar 16% dan total digestible nutrients (TDN) 65% dengan perlakuan T 0 : pakan tanpa urea; T 1

Parameter yang diamati adalah kecernaan bahan kering pakan, kadar air feses, perluasan feses pipih (PFP) dan proporsi partikel kasar feses (PPKF). Data dianalisis dengan ragam dan uji korelasi-regresi untuk mengetahui hubungan antar parameter. Hasil penelitian menunjukkan bahwa level urea dalam pakan sebesar 0 -1,2% bahan kering pakan tidak menyebabkan perbedaan kecernaan bahan kering, kadar air, tingkat PFP dan PPKF. Terdapat hubungan negatif kuat antara tingkat kecernaan bahan kering dengan kadar air feses (r = -0,665) dan tingkat PFP (r = -0,553), serta terdapat hubungan positif kuat antara tingkat kecernaan bahan kering pakan dengan tingkat PPKF (r = 0,608). Simpulan penelitian ini adalah kadar air feses, tingkat PFP dan PPKF dapat digunakan untuk mengetahui kualitas pakan yang diberikan. Apabila feses memiliki tekstur lebih halus, kering dan partikel kecil maka kecernaan pakannya lebih tinggi, sebaliknya apabila feses bertekstur kasar, basah, partikel besar maka kecernaan pakan lebih rendah. ABSTRACT This study aimed to explore physical characteristics and its correlation to feed digestibility in goat. Sixteen Ettawah Grade goats in the second milk production periods and in the 4-5 th month of lactation were used in this study. The study was arranged with completely randomized block block design based on milk production as replications. The goats were fed ration containing 16% of crude protein and 65% of total digestible nutrients (TDN). Some of crude protein content were supplied by urea. The treatments were control ration (without urea; T0), ration with 0.4% urea (T1), ration with 0.8% urea (T2), and ration with 1.2% urea (T3). Parameters observed were feed digestibility, fecal extended level (FEL), and fecal rough particle distribution (FRPD). Data were analyzed using correlation-regression to find the correlation between fecal characteristics and feed digestibility. The results showed that urea content in the rations up to 1.2% of dry matter did not affect dry mater digestibility, water content and fecal characteristics (FEL and FRPD). There were highly negative correlation (r= -0.665) between feed digestibility and water content of feces as well as feed digestibility and FEL (r= -0.553), while correlation between digestibility and FRDP was positive (r=0.608). The conclusion of this study was water content, degree of FEL and FRPD can be used to determine the quality of feed. If feces composed of finer texture, dried and small particles indicated having better digestibility, while if feces composed of rough texture, wet, and large particles indicated having low digestibility.
