Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh berbagai level (tingkat) daun kaliandra kering pada pakan terhadap N-NH3 dan VFA kambing laktasi. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Duapuluh ekor kambing laktasi dibagi menjadi 4 kelompok perlakuan, yaitu: R1(0% daun kaliandra kering), R2 (10% kaliandra kering), R3 (20% kaliandra kering), dan R4 (30% kaliandra kering), dan masing-masing perlakuan terdiri dari 5 ekor kambing PE laktasi sebagai ulangan. Produksi NH3 rumen diukur dengan teknik Micro-Diffuse Conway dan konsentrasi VFA total menggunakan Chromatography gas-cair. Kajian menunjukkan bahwa konsentrasi N-NH3 rumen pada penelitian ini adalah: R1 92.37 mg/L, R2 99.98 mg/L, R3 102.68 mg/L , dan R4 117.64 mg/L, sedangkan konsentrasi VFA total adalah: R1 158.67 mM, R2 166.67 mM, R3 174.00 mM , dan R4 177.00 mM. Hasil analisis statistik menunjukkan bahwa level kaliandra kering di dalam pakan berpengaruh tidak nyata terhadap konsentrasi NH3 dan VFA rumen kambing laktasi. Disimpulkan bahwa penggunaan daun kaliandra kering sampai taraf 30% di dalam pakan tidak berpengaruh jelek (negatf) terhadap konsentrasi NH3 dan VFA rumen kambing laktasi.

Abstract

The objective of the study was to evaluate the effect of Sapindus rarak extract (SRE) with or without garlic extract (GE) on in vitro ruminal fementation. This research was conducted experimentally with a randomized block design, with 7 treatments and 5 blocks. The treatments were: R0:  dairy cow feed; R1: R0 + 1.5 ppm Cr + 0.3 ppm Se + 40 ppm Zn; R2: R1 + 1.8 g/kg methanol extract of lerak fruit  meal (SRE); R3: R2 + 0.25 ppm of garlic extract (GE); R4: R2 + 0.50 ppm of GE; R5: R2 + 0.75 ppm of GE; R6: R2 +1.0 ppm of GE. The results showed that the supplementation of SRE alone or without GE did not affect the pH, however, it decreased crude fiber digestibility. The supplementations of SRE and GE, decreased crude fibre digestibility as much as 13.01% up to 16.6%. The supplementation of 1.8 g/kg SRE + 0.25 ppm GE in the dairy cattle diet was able to decrease ace-tate, protozoal population and increase propionate. The supplementation of 1.8 g/kg SRE and 0.25 ppm garlic represents the best combination for dairy cattle feed in improving ruminal fermentation based on feed digestibility, fermentation products, and rumen bacterial population.
