Suplementasi Trigliserida Terproteksi dalam Ransum Sapi Perah terhadap Fermentabilitas dan Kecernaan In Vitro

Abstract

Penelitian ini bertujuan menguji karakteristik trigliserida terproteksi sebagai suplemen ransum sapi perah dan pengaruhnya terhadap fermentabilitas dan kecernaan in vitro. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 4 perlakuan dan 4 kelompok. Perlakuan terdiri dari P0 = ransum kontrol berupa rumput gajah 45,73% + konsentrat 54,27%, P1 = P0 + 2% trigliserida terproteksi, P2 = P0 + 4% trigliserida terproteksi, P3 = P0 + 6% trigliserida terproteksi. Data yang diperoleh dianalisis dengan Analysis of Varian (ANOVA) dan untuk hasil perlakuan yang berbeda akan diuji lanjut dengan Uji Duncan. Penambahan trigliserida terproteksi berpengaruh nyata (P<0,05) terhadap total populasi protozoa, KcBK, KcBO, kecernaan NDF dan ADF. Berdasarkan penelitian ini, dapat disimpulkan bahwa suplementasi trigliserida terproteksi hingga taraf 6% tidak memengaruhi kondisi pH rumen, meningkatkan konsentrasi NH3 dan VFA total, tetapi secara signifikan menurunkan populasi protozoa, kecernaan bahan kering dan bahan organik serta kecernaan fraksi serat.

This study was aimed to examine the characteristics of protectedtriglycerides as a ration supplement for dairy cows and its effect on fermentabilityand in vitro digestibility. This study used a Randomized Group Design with4treatments and 4 groups. The treatments consisted of P0 = control rationof elephant grass 45.73% + concentrate 54.27%, P1 = P0 + 2%protectedtriglycerides, P2 = P0 + 4% protected triglycerides, P3 = P0 + 6%protectedtriglycerides. The data obtained were analyzed by Analysis of Variance (ANOVA) and for different treatment results will be further tested by Duncan's Test. Theaddition of protected triglycerides had a significant effect (P<0.05) on the total protozoa population, KcBK, KcBO, NDF and ADF digestibility. Based onthisstudy, it can be concluded that supplementation of protected triglycerides upto6% level did not affect rumen pH condition, increased NH3 and total VFAconcentrations, but significantly decreased protozoa population, dry matter andorganic matter digestibility and fiber fraction digestibility.
