Utilization of Nutrition and Performance of Local Male Goats Given Concentrate Containing Fermented Cow Rumen Content Waste

/in /by

The aim of the research was to determine the effect of feeding concentrates containing fermented cow rumen waste on the consumption and digestibility of dry matter, organic matter, nitrogen, NDF and ADF of local male goats. This research was conducted for 5 months using 20 local male goats aged 8-10 months with an average body weight of 11.71 kg and CV 12%. This experimental research used a completely randomized design with 4 treatments and 5 replications. The treatment is as follows P0: Kume grass 70% + concentrate 30% (without fermented cow rumen contents); P10: kume grass 70% + concentrate 30% (concentrate contains fermented cow rumen contents); P20: kume grass 70% + concentrate 30% (concentrate contains 20% contents of fermented cow  rumen); P30: kume grass 70% + concentrate 30% (concentrate contains 30% contents of fermented cow rumen). The results of the variance analysis showed that the treatment had no significant effect of p>0.05 on the consumption and digestibility of dry matter, organic matter, nitrogen, NDF and ADF in local male goats. The conclusion of this research is that concentrate supplementation containing fermented cow rumen waste up to a level of 30% gives relatively the same effect between each treatment on the consumption and digestibility of dry matter, organic matter, nitrogen, NDF and ADF of local male goats.

Evaluation of Dry Matter, Organic Matter and Crude Protein Digestibility in New Zealand White Rabbits with Different Sludge Percentages

/in /by

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.
