Karakteristik Fisik, Fermentabilitas, dan Kecernaan In Vitro Ransum Sapi Perah yang Disuplementasi Prill Fat Terhidrogenasi

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh suplementasi prill fat terhidrogenasi terhadap karakteristik fisik, fermentabilitas, dan kecernaan in vitro dari ransum sapi perah. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 4 kelompok berupa frekuensi pengambilan cairan rumen. Adapun perlakuan tersebut adalah P0 = Ransum kontrol berupa rumput gajah 45,73% + konsentrat 54,27%, P1 = P0+ 2% prill fat terhidrogenasi, P2 = P0+ 4% prill fat terhidrogenasi, dan P3 = P0+ 6% prill fat terhidrogenasi. Parameter yang diamati meliputi pH, total VFA, konsentrasi NH3, populasi protozoa, total bakteri, KCBK, dan KCBO, kecernaan NDF, ADF, dan hemiselulosa. Data yang diperoleh dianalisis dengan Analysis of Variance (ANOVA) dan untuk hasil perlakuan yang berbeda akan diuji lebih lanjut dengan Uji Duncan. Hasil penelitian menunjukkan bahwa suplementasi prill fat terhidrogenasi berpengaruh nyata (P<0,05) terhadap total populasi protozoa, KCBK dan KCBO. Dapat disimpulkan penggunaan hingga taraf 2% efektif, karena tidak memengaruhi fermentabilitas rumen, kecernaan bahan kering dan organik serta kecernaan serat.

This study aimed to evaluate the effect of hydrogenated prill fat supplementation on the physical characteristics, fermentability, and in vitro digestibility of dairy cow rations. This study used a Randomized Group Design (RBD) with 4 treatments and 4 groups in the form of rumen fluid collection frequency. Treatments included P0: control diet (45.73% elephant grass + 54.27% concentrate), P1: P0 + 2% hydrogenated prill fat, P2: P0 + 4% hydrogenated prill fat, and P3: P0 + 6% hydrogenated prill fat. Parameters observed included pH, total volatile fatty acids (VFA), ammonia nitrogen (NH3) concentration, protozoa and bacteria population, neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose digestibility. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's test for further comparison. The results showed that supplementation of hydrogenated prill fat had a significant effect (P<0.05) on the total protozoa population, KCBK and KCBO. It can be concluded that the use of up to 2% level is effective, because it does not affect rumen fermentability, dry and organic matter digestibility and fiber digestibility.
