SABUN KALSIUM DARI PALM FATTY ACID DISTILLATE SEBAGAI SUPLEMEN PAKAN SAPI PERAH

Abstract

Penelitian ini bertujuan menguji karakteristik sabun kalsium yang berasal dari palm fatty acid distillate (PFAD) sebagai suplemen pakan sapi perah dan pengaruhnya terhadap fermentabilitas dan kecernaan secara in vitro. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 4 ulangan. Perlakuan tersebut adalah P1 = Ransum kontrol berupa rumput gajah 45,73% + konsentrat 54,27%, P2 = P1+ 2% sabun kalsium, P3 = P1+ 4% sabun kalsium, dan P4 = P1+ 6% sabun kalsium. Parameter yang diamati meliputi pH, populasi protozoa, populasi bakteri total, konsentrasi VFA total, konsentrasi NH3, KcBK dan KcBO, kecernaan NDF, ADF dan hemiselulosa. Data yang diperoleh dianalisis dengan Analysis of Variance (ANOVA) dan perlakuan yang berbeda nyata akan diuji lanjut dengan Uji Duncan. Hasil penelitian menunjukkan sabun kalsium dari PFAD memiliki karakteristik fisik yang baik dan suplementasinya hingga 6% berpengaruh nyata terhadap total populasi protozoa dan konsentrasi VFA. Suplementasi pada taraf 2–2,2% efektif digunakan karena tidak memengaruhi fermentabilitas rumen dan kecernaan bahan kering dan organik serta kecernaan serat.

palm fatty acid distillate (PFAD) as a dairy cattle feed supplement and its effect on in vitro fermentability and digestibility. The study employed a Randomized Block Design (RBD) with 4 treatments and 4 replications. The treatments were as follows: P1 = control diet consisting of 45,73% napier grass + 54,27% concentrate, P2 = P1 + 2% calcium soap, P3 = P1 + 4% calcium soap, and P4 = P1 + 6% calcium soap. The parameters observed included pH, , protozoa population, total bacteria, VFA concentration, NH3 concentration, dry matter and organic digestibility, NDF, ADF and hemicellulose digestibility, Data were analyzed using Analysis of Variance (ANOVA), and significant differences were further tested using Duncan's Multiple Range Test. The results showed that calcium soap from PFAD had good physical characteristics and, at levels up to 6%, did not affect rumen pH, bacterial population, NH3 concentration, or the digestibility of dry matter, organic matter, and fiber. Supplementation at 2–2.2% was most suitable as it maintained rumen fermentability and nutrient digestibility
