Abstract

The study was aimed to evaluate the increasing levels of ration energy, with fat-rich unsaturated fatty acids from sunflower oil on the nutrient intake, rumen fermentability and performance of ewes. The experiment used fifteen ewes of 1.5 years old, primiparous, caged individually with their lambs and conducted three treatments and five replications from a completely randomized designed. Those treatments included R1= ration with 0% sunflower oil addition, R2= ration with 4%sunflower oil addition, R3= ration with 6% sunflower oil addition. The variables consisted of dry matter intake, nutrients, ewes performances (birth weight, weaning weight, decreased of body weight), total and partial VFA, the ratio of acetate: propionate, methane production, protozoa and bacterial population. Data were analyzed statistically and descriptively. The results showed that the treatments did not influence dry matter intake and nutrients,. rumen fermentability and ewes performances. Although the treatments increased (P<0.01) fatconsumption and reduced shrinkage of body weight. It can be concluded that the adding sunflower oil as the resource of unsaturated fatty acids up to 6% of the ration was not negatively affected the fermentability of rumen, moreover can improve ewes body condition and, accelerated body weight recovery

Abstract

The PUFA (polyunsaturated fatty acid)-concentrates containing fatty acid sources (roasted corn grain,roasted soy bean meal, and corn oil) was designated as PUFA- concentrate for dairy goat. There werefour PUFA-concentrates, no supplement (PC0), 0.5% or 5 g yeast (PCY), 2% or 20 g curcuma powder(PCC), and 0.5% or 5g yeast with 2% or 20g curcuma powder (PCM). These PUFA-concentrates wereevaluated for nutrients and fatty acid contents during 2, 4, and 6 weeks of storage. The application oftreatments utilized in this research was completely randomized design with repeated measurement andsplit plot statistical analysis. Results showed that the contents of dry matter, organic matter, ether extract,crude protein, N-free extract, gross energy, acid detergent fiber, Ca, P, and Saccharomyces cereviseaewere significantly (P<0.05) remained stable as caused by unchained moisture of PUFA-concentrate withcombined supplements (Y5C20) in the 6 weeks of storage. The total PUFA (P), P/S, monounsaturatedfatty acid (MUFA), and long chained fatty acid contents tended to be high in PUFA-concentrate with 2%or 20 g curcuma powder. Whereas, the PUFA-concentrate with a combination of 0.5% or 5 g yeast and2% or 20 g curcuma powder was higher in unsaturated (U) fat and the ratio of U/S. In conclusion, combining all nutrient performances during the storage of 2 to 6 weeks, the PUFA-concentrate with0.5% or 5 g yeast and 2% or 20 g curcuma powder was considered nutritionally good.

Abstract

Eceng gondok (Eichhornia crassipes) adalah tanaman air yang melimpah namun sering dianggap sebagai gulma dan potensi sebagai pakan alternatif untuk unggas karena kandungan nutrisinya yang baik.Namun, tingginya kandungan serat kasar menjadi kendala utama dalam pemanfaatannya. Penelitian ini bertujuan untuk mengetahui pengaruh variasi dosis inokulum dan lama inkubasi terhadap kandungan energi, bahan organik (BO) dan pH eceng gondok yang difermentasi menggunakan Neurospora crassa. Penelitian ini menggunakan rancangan acak lengkap pola faktorial dengan variasi dosis inokulum (1%, 2%, 3%) dan lama inkubasi (5 dan 7 hari). Hasil penelitian menunjukkan bahwa fermentasi eceng gondok pada dosis 1% dan lama fermentasi 7 hari  dapat menurunkan kandungan serat kasar. Kesimpulan dari penelitan ini adalah dosis inokulum 1% dengan lama fermentasi 5 hari dapat menurunkan kandungan  serat kasar 23,57%, dengan kandungan energi 3753,38 Kkal/kg, kandungan bahan organik 89,77% dan pH 7,47.
