Abstract

Digestibility is a description of the ability of feed material that can be utilized by livestock. Higher digestibility of feed material means the total amount of feed content that can be digested in the digestive tract. This study aimed to obtain the proportion of the use of fermentation concentrate in rumen fermentation based on in vitro. The feed used consisted of 7 treatments as follows P1 (20% Pennisetum purpureum: 80% concentrate), P2 (30% P.purpureum : 70% concentrate), P3 (40% P.purpureum : 60% concentrate), P4 (50% P.purpureum : 50% concentrate), P5 (20% concentrate: 80% P.purpureum), P6 (30% concentrate: 70% P.purpureum) and P7 (40% concentrate: 60% P.purpureum). Dry matter digestibility (DMD) and organic matter digestibility (OMD) were done using Theodorou method. Gas production was measured when the samples were incubated at 39oC in the waterbath incubator at hours 2, 4, 6, 8, 10, 12, 24, and 48. Approximately 0.75 g of feed formulation was mixed with 75 mL of rumen fluid buffer. The rumen fluid is taken from 3 fistulated cattles prior to morning feeding. A complete randomized design with three replicates was used. Asymptotic gas production and kinetics were estimated by the Orskov’s model. The results of this study showed that P2 and P3 treatment showed the best digestibility among others treatment with 71.63% ; 71.06% of DMD and 76.42% ; 71.65% of OMD. In conclusion, P2 and P3 treatment can be used as feed for beef cattle.

Abstract

Parboiled rice product has been widely produced by industry in the developing countries. The increasing of parboiled rice product will consequently increased rice bran waste. Therefore, the objective of the study was to analyze the effect of parboiling processes on nutritional value of rice bran and evaluate nutritional value of parboiled rice bran in the rumen fermentation using in vitro digestibility method. The experiment was arranged in completely randomized factorial design with 2 factors and 3 replications. The first factor is types of rice bran from different rice plant variety consisted of LIPI GO1, LIPI GO2, LIPI GO4, and Sintanur. The second factor is soaking time consist of 0 minute (control), 30 minutes and 60 minutes. Data were analyzed by using ANOVA and significant effects of each treatment were further analyzed by using the least significant difference by Duncan multiple range test (P<0.05). Kinetic parameters of Ørskov’s equation were obtained by non-linear regression procedure. Results showed that the quality of parboiled rice bran was significantly affected by the parboiling process such as soaking periods and rice variety. Chemical composition, rumen gas production, and digestibility of rice bran differ depends on rice variety. Soaking for 30 minutes and 60 minutes decreased organic matter, crude protein, and increased crude fiber (P<0.05). Moreover, soaking rice grain for 60 minutes increased crude fat. The longer of soaking periods decreased of total gas, potential gas production, gas production rate and total organic matter digestibility (P<0.05).

Abstract

Male Kamang ducks are one of the local ducks in West Sumatran germplasm originating from Tilatang Kamang and Kamang Magek Districts, Agam Regency, West Sumatera. The balance of metabolizable energy and crude protein (EM/P) in preparing the ration for Kamang ducks must be considered because it is closely related to the efficiency and growth of the ducks. Preparing the feed formulation for Kamang ducks with the right energy and protein balance will support their productivity. The research used male Kamang ducks in the grower phase, which is 3 to 7 weeks of age. Feed Treatment was metabolizable energy of 2800 kcal/kg with 17%, 18%, and 19% crude protein levels. The design used was completely randomized, with 3 treatments and 6 replications. The research showed no significant effect of treatments on feed consumption, body weight gain, or conversion ratio of male Kamang ducks in the grower phase; however, from the treatments, the highest income based on the IOFC value was ration B. In male Kamang ducks, good performance in balance of ME/P are 147.37 to 164.71 with the highest Income Over Feed and Cost (IOFC) value and lower fat abdominal at ME/P 155.55.
