Pengaruh Suplementasi Rumput Laut terhadap Kecernaan Bahan Kering dan Bahan Organik Ransum Sapi Potong
Abstract
This research aims to determine the effect of providing seaweed in the ration on the digestibility of dry matter and organic matter in beef cattle. This research was carried out in October-December 2023 at KPT Maju Sejahtera South Lampung and proximate analysis was carried out at the LabTIAP Serpong Nutrition Laboratory, National Research and Innovation Agency (BRIN). This research was carried out using a Randomized Block Design (RAK) consisting of 3 treatments and 6 replications, using 18 local beef cattle. The treatment given is P1; pakchong grass + concentrate (ratio 70%:30% DM feed), P2; pakchong grass + concentrate (ratio 70% : 30% DM feed) + seaweed Eucheuma cottonii (4% DM feed) and P3; pakchong grass + concentrate (ratio 70% : 30% DM feed) + seaweed Eucheuma cottonii (4% DW feed) + biochar (0.05% DM feed). The variables observed were Dry Matter Digestibility (KcBk) and Organic Matter Digestibility (KcBo). In treatment P3, the results showed no significant difference from P1 and P2 regarding the dry matter digestibility value. In treatment P3, the results showed no significant difference between P1 and P2 regarding organic material digestibility. Based on the research that has been carried out, it can be concluded that the addition of seaweed to beef cattle rations produces the highest average digestibility of dry matter, namely at P3 was 64,95%; P2 was 63.41%, and P1 was 61,34%, meanwhile for organic materials, the highest average digestibility is P3 was 65,94%; P2 was 63,62%, and P1 was 62,59%.
