KANDUNGAN PROTEIN DAN SERAT KASAR AMPAS TEBU YANG DI AMONIASI MENGGUNAKAN UREA DENGAN DOSIS YANG BERBEDA

Abstract

This research was conducted to determine bagasse's crude protein and fibre content, which was
ammoniated using urea at different doses. This research method used a completely randomized
design (CRD) with four treatments and five replications totalling 20 trials consisting of (P0)
bagasse + 5% bran + 0% urea, (P1) bagasse + 5% bran + 2.5 % urea, (P2) bagasse + 5% rice bran
+ 5% urea and (P3) bagasse + 5% rice bran + 7.5% urea. Analysis of crude protein and crude fibre
was carried out for seven days. Data were analyzed whit by Analysis of Variance (ANOVA)
followed by Duncan's multiple range test assisted by IBM's SPSS Ver 26 software. The results
showed that the addition of urea at different doses had a significant effect (p<0.05) on increasing
crude protein content and decreasing crude fibre content. The use of 7.5% urea resulted in the
highest crude protein content of 22.53% and the lowest crude fibre content of 31.36%. This
research needs to be continued to determine in vitro digestibility before being applied to ruminants
as animal feed ingredients.
