Abstract :

This study aims to determine the effect of the addition of sludge with different percentages in the ration of New Zealand White rabbits on the digestibility of dry matter, organic matter and crude protein produced. sludge used comes from dairy cow feces which are then dried and ground before finally added to the ration. The research design used a group randomized design with five treatments and two groups. The groups used were rabbit body weight groups, namely small and large groups, while the treatments used included P0 (control), P1 (basal feed + 5% sludge), P2 (basal feed + 10% sludge), P3 (basal feed + 15% sludge) and P4 (basal feed + 20% sludge). This study was conducted for 7 weeks, of which the first week was the adaptation stage and the next 6 weeks was maintenance. Collection of feces to measure digestibility was carried out in the fifth week. The data obtained were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) if there were significant differences. The results showed a significant difference between treatments on dry matter digestibility, organic matter digestibility and crude protein digestibility. Based on the results obtained, it is concluded that the best percentage that can increase digestibility is P1 or the addition of sludge as much as 5% in the ration.
