Penelitian ini bertujuan untuk mengevaluasi pengaruh level protein kasar berbeda terhadap kualitas fisik, kimia, dan respons konsumsi pelet pada tikus laboratorium (Rattus norvegicus) fase maintenance. Penelitian menggunakan rancangan acak lengkap dengan empat perlakuan level protein P0 = pakan komersial Rat-Bio, P1 = protein kasar 13%, P2 = 11,5%, P3 = 10%. Kualitas kimia, daya serap air, penampakan fisik, dan kenaikan bobot badan dianalisis secara deskriptif, sedangkan kualitas fisik, konsumsi, dan bobot badan dianalisis statistik dengan ANOVA dan uji lanjut Tukey HSD. Kadar PK menurun diikuti dengan kenaikan SK. Perlakuan berbeda nyata (P<0>pellet durability index (PDI), dan hardness, dengan PDI terendah pada P1 dan hardness tertinggi pada P2, tetapi tidak terhadap berat jenis dan modulus of uniformity serta modulus of fineness. Pada uji in vivo, konsumsi bahan kering P2 lebih tinggi dibandingkan P0 dan ADG P3 lebih rendah dibandingkan P0 (P<0>

This study aimed to evaluate the effect of different crude protein levels on the physical quality, chemical quality, and consumption response of pellets in maintenance-phase laboratory rats (Rattus norvegicus). The study used a completely randomized design with four protein level treatments (P0 = commercial Rat-Bio feed, P1 = 13% crude protein, P2 = 11.5%, P3 = 10%). Chemical quality, water absorption, physical appearance, and body weight gain were analyzed descriptively, whereas physical quality, feed intake, and body weight were statistically analyzed using ANOVA followed by Tukey's HSD test. Crude protein content decreased, accompanied by an increase in crude fiber. The treatments significantly affected (P<0>
