Abstract

The aim of the experiment was to evaluate the effect of increamental level portulaca flour (Portulaca oleracea L) inclusion into commercial ration on total cholesterol, omega 3 and omega 6 of broiler meat. One hundred DOC were used in this experiment. Method used was completely randomized design (CRD) four treatments withfive replicates. The treatments were Kr00= commercial ration without portulaca flour, Kr25= commercial ration + 2,5% portulaca flour, Kr50= commercial ration + 5%portulaca flour, and Kr75= commercial ration + 7,5% portulaca flour. The results showed that including portulaca flour into commercial ration inhibit cholesterol formation resulted in a lower total cholesterol concentration by 24% in the meat. Increasing level of portulaca flour in the ration did not have effect on omega 3 concentration, but significantly reduced omega 6 concentration from 410,44 mg/100 g meat to195,52 mg/100 g meat.It can be concluded that inclusion of portulaca flour in the ration can reduce total cholesterol concentration and improve the ratio of omega 6 : omega 3 in the meat of broiler chicken. ABSTRAK Suatu penelitian bertujuan untuk mengkaji pengaruh penambahan tepung krokot (Portulaca oleracea L) dalam ransum terhadap kandungan total kolesterol, omega 3 dan omega 6 dalam daging ayam broiler. Penelitian ini menggunakan 100 ekor ayam broiler. Metode yang digunakan adalah metode percobaan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dan 5 ulangan. Empat perlakuan tersebut Kr00= ransum komersial tanpa tepung krokot, Kr25= ransum komersial + 2,5% tepung krokot, Kr50= ransum komersial + 5% tapung krokot, dan Kr75= ransum komersial + 7,5% tepung krokot. Hasil penelitian menunjukan bahwa penambahan tepung krokot dalam ransum menghambat pembentukan kolesterol sehingga menurunkan total kolesterol sebesar 24%. Kandungan asam lemak omega 3 dalam daging tidak nyata dipengaruhi oleh level tepung krokot, sebaliknya asam lemak omega 6 menurun secara drastis dari 410, 44 mg/100 g daging ke 195,52 mg/100 g daging, sehingga terjadi penurunan rasio omega 6 : omega 3 dari 6,43 ke 3,77. Disimpulkan bahwa penambahan tapung krokot dalam ransum komersial untuk broiler dapat menurunkan kadar kolesterol daging dan menyebabkan rasio omega 6 : omega 3 menjadi lebih baik

Abstract

The main problem in preservation of protein source forages in silage making is spoilage due to high buffering characteristic of protein. This might relates to low carbon-nitrogen (C-N) ratio in these plants. This study aimed at determining the best level of C-N ratio in ensilage process of a grass-legume mixture. A 3x4 completely randomized design (CRD) was deployed to test three C-N ratio levels as treatments. The treatments were CN20 (Mucuna sp + kume grass + rice bran to reach C-N ratio of 20, or 30 (CN30) or 40 (CN40). Variables measured were dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), and crude fiber (CF) content of the silage. Data were analyzed using General Linear Model for CRD with an alfa value of 0.05. Treatment differences were determined using Duncan test. The results showed that C-N ratio had high significant effects on DM content (ranged from 22.5 to 32.0%), and CP content (ranged from 7.5 to 9.6%). Significant treatment effects were detected in OM content (ranged from 90.5 to 91.8%), and EE content (ranged from 2.82 to 3.66%). Meanwhile, CF was not effected by C-N ratio (ranged from 39.0 to 3.0%. 44.2%). It could be concluded that C-N the ratio of 30 is the best treatment in silage making using mixture of lelehanak-kume grass as it shows the highest OM content and had no significant difference with CN20 in CP content.
