ABSTRAK. Penelitian ini bertujuan untuk mengetahui pengaruh Coleus amboinicus L. (daun bangun-bangun) dan Sauropus androgynus L. Merr (daun katuk) terhadap produksi susu kambing Peranakan Etawah. Enam belas ekor kambing Peranakan Etawah laktasi digunakan pada penelitian ini dengan rancangan acak kelompok 4 x 4. Perlakuan P0 = 30% konsentrat +70% hijauan, P1= P0+6 g/kg BK Coleus amboinicus L., P2 = P0+6 g/kg BK Sauropus androgynus L. Merr, dan P3 =3 g/kg BK Coleus amboinicus L. +3 g/kg BK Sauropus androgynus L. Merr. Peubah yang diamati adalah konsumsi ransum (bahan kering, protein kasar, lemak kasar, serat kasar, Ca dan P), produksi susu dan kualitas susu (bahan kering, bahan kering tanpa lemak, lemak, protein, casein dan berat jenis). Data dianalisis menggunakan ANOVA, jika berbeda nyata antar perlakuan dilakukan uji lanjut berganda Duncan. Perlakuan pemberian Coleus amboinicus L. dan Sauropus androgynus L. Merr tidak memengaruhi konsumsi bahan kering (BK) pakan, protein kasar (PK), lemak kasar (LK), serat kasar (SK), Ca dan P (P0,05). Perlakuan Coleus amboinicus L. dan Sauropus androgynus L. Merr dapat meningkatkan produksi susu (P0,05), namun tidak memengaruhi kualitas susu (bahan kering, bahan kering tanpa lemak, lemak, protein dan casein) (P0.05) dan sangat nyata memengaruhi berat jenis (BJ) susu kambing Peranakan Etawah (P0,01). Disimpulkan bahwa pemberian Coleus amboinicus L. dan Sauropus androgynus L. Merr dapat meningkatkan produksi susu, tetapi tidak memengaruhi konsumsi ransum dan kualitas susu. (Increased production of Etawah cross-breed goat milk by giving Coleus amboinicus Lour and Sauropus androgynus L. Merr) ABSTRACT. This study intended to determine the effect of Coleus amboinicus L. and Sauropus androgynus L. Mers on Etawah crossbreed goat milk production. Sixteen lactating Etawah crossbred goats were used in the 4 x 4 randomized block experiment consisted of four treatments, P0 = 30% concentrate + 70% forage, P1 = P0 + 6 g/kg Coleus amboinicus L., P2 = P0 + 6 g/kg Sauropus androgynus L. Merr and P3 = 3 g/kg Coleus amboinicus L. + 3 g/kg Sauropus androgynus L. Merr on dry matter basis. The variables measured were consumption (dry matter, crude protein, crude fat, crude fiber, Ca and P), milk production and milk quality (dry matter, milk solid non fat, protein, specific gravity). Data were analyzed by ANOVA, if there were differences between treatments, Duncan's multiple-test was carried out. The result showed that, the addition of Coleus amboinicus L. and Sauropus androgynus L. Merr in ration did not affect dry matter consumption, crude protein, crude fat, crude fiber, Ca and P (P0.05). Coleus amboinicus L and Sauropus androgynus L. Merr significantly increased milk production (P0.05), and highly affected specific gravity of Etawah crossbreed goat milk (P 0.01), but did not affect milk quality (dry matter, dry ingredients non fat, protein fat and casein) (P0.05). It could be concluded that the addition of Coleus amboinicus L. and Sauropus androgynus L. Merr increased milk production, but did not affect consumption and milk quality.

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 4-5th 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.
