Abstract

In livestock production, the crucial goal is to minimize the production cost, especially feeding cost, without compromising the farm and animal performances. Empty fruit bunch (EFB) is one of the abundant agricultural by-products from oil palm plantation, that locally available. The EFB has been used the farmers as one of the feedstuffs in their farms, but still, studies on assessing its effects on ruminal degradability are scarce. Thus, this study was performed to determine in vitro rumen degradability of formulated Napier grass (Pennisetum purpureum) and empty fruit bunch (Elaeis guineensis) as goats feed. Rumen fluid from two 2-year-old Boer crossbreed goats were collected and mixed with buffer and substrate. Total mixed ration diet that was used is 60% roughage (e.g. Napier grass and EFB) and 40% concentrate. Four level of treatments were compared namely: 0% of EFB, 25% of EFB, 50% of EFB and 75% of EFB. In vitro incubation using syringes was carried out at 39°C ± 1°C for 72 hours. Total gas production was recorded at 1, 2, 4, 6, 9, 24, 33, 48 and 72 hours of incubation. The pH of fermented rumen fluid, total short chain fatty acids (SCFA) and in vitro organic matter digestibility (IVOMD) were determined at the end of 72h incubation. The results revealed that the total gas production for 25% EFB is the highest followed by 50% EFB, 75% EFB and CON but there is no significant between all of the treatment groups. The treatment of 25% EFB shows the optimal pH (6.44) for rumen microbial fermentation and produce higher SCFA production (28.4784 mmol/g) (p>0.05) while other groups did not differ significantly. The IVOMD showed that 25% EFB (1.7733%) also had a significantly digestibility as compared to 50% EFB (1.7600%), 75% EFB (1.2666%) and CON group (0.9600%). In conclusion, feed with 25% EFB shows an improvement in in vitro rumen degradability and could be considered as optimum inclusion in ruminants feed.
