ABSTRAK
Penelitian ini telah dilaksanakan di Laboratorium Nutrisi Ternak Ruminansia dan Kimia Makanan Ternak, Fakultas Peternakan, Universitas Padjadjaran, Jatinangor, Sumedang. Bulan Februari 2013. Penelitian ini bertujuan untuk mengetahui Pengaruh Tingkat Penggunaan Kromium (Cr) Organik dalam Ransum Sapi Perah terhadap Kecernaan Bahan Kering dan Bahan Organik (in vitro). Metode penelitian yang digunakan adalah
eksperimental menggunakan rancangan acak lengkap (RAL) dengan empat macam perlakuan sebagai berikut : R0 = Kontrol, R1 = 1,5 ppm, R2 = 3,0 ppm, dan R3 = 4,5 ppm Kromium (Cr) organik. Setiap perlakuan diulang sebanyak lima kali. Data yang diperoleh diuji menggunakan metode uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa pemberian kromium organik sebanyak 1,5 ppm sudah menurunkan kecernaan bahan kering ransum, sedangkan kecernaan bahan organik menurun setelah pemberian kromium organik sebanyak 3,0 ppm ke dalam ransum.

ABSTRACT
This research was conducted on the Laboratory of Ruminant Nutrition and Feed Chemical, Faculty of Animal Husbandry, Padjadjaran University, Jatinangor, Sumedang. It was held on February 2013. The aim of this research is to find out the effect of level of chromuim (Cr) organic usage in dairy cattle’s ration towards the digestibility of dry and organic matter. This research used complete randomized design (CRD) as the experimental method. In this exeriment there are four treatment, they are : R0 = control, R1 = 1, 5 ppm, R2 = 3,0 ppm, and R3 = 4,5 ppm of chromium (Cr) organic. Each treatments were repeated in five times. The data was obtain by using
Duncan’s multiple range test. The result showed that the use level of 4,5 ppm
of organic chromium in dairy cattle rations low the dry matter digestibility, of the rations, but lower the organic matter digestibility of the rations. while the provision of 1.5 ppm can provide the highest organic matter digestibility.
