Vegetables Waste Utilization as Feed Beef Cattle

Market Waste is mostly composed of vegetables waste which has the potential to become animal feed but constrained by the condition that easily become rotten and can not be stored for long time. So that, before it can be used as animal feed, it is better that it first made into silage. In line with that, Jakarta Assessment Institute for Agricultural Technology (Jakarta AIAT) had conducted a study that aimed to find an appropriate formula of feed beef cattle with silage using waste materials from market in Jakarta.

Assessment used a completely randomized design (CRD) with 4 kinds of treatment that P1 (60% mixture of vegetables waste + 20% stack (pile) + 20% bran), P2 (60% mixture of vegetables waste + 20% stack + 20% concentrate), P3 (60 % mixture of vegetables waste + 20% cassava flour + 20% bran) and P4 (60% mixture of vegetables waste + 20% cassava flour + 20% concentrate).

The results showed that treatments that were close to the water content of silage in the initial conditions were P1 and P3. Protein levels in P1 (16.32%) did not differ with P3 (16.38%) but significantly different from P2 treatment (5.92% ) and P4 (5.48%). Meanwhile, weight decrease value of P1 (456 g) was not different from the P3 (445 g) but significantly different from P2 (299 gr) and P4 (308 g), as same as the pH of the silage of P1 (3, 80) did not differ by treatment P3 (4.10) but significantly different from treatment P2 (5.00) and P4 (5.00). Overall, the most good quality silage gave by P1 and P2 which characterized by fragrant smells like tape, green and yellow colour, and dry with a soft texture. The storage time of those silage could be up to 1.5 months. Application of silage-making from market waste at the farm level gave result that waste silage could be consumed by cattle, goats and cattle. So that the farmers were excited to continue to make silage as the main forage which can overcome scarcity of forage in the dry season.
