Abstract

Solid substrate fermentation by Aspergillus niger has been carried out to improve the nutritive value of palm oil sludge (POS). POS was fermented aerobically for four days in a fermentor chambers (28°C, RH 80%), with 60% moisture content Some of the product was further incubated anaerobically for 2 days at 28°C. Both products from aerobic and anaerobic fermentation processes were dried by various methods, i.e. sunlight, oven at 60°C, oven with blower at 40°C, at the moisture content less than 11%. Results of the drying methods were also compared with the fresh fermented product. Statistic analysis using factorial design (2 x 4) showed that there was no interaction between kind of fermentation processes (aerobic and anaerobic) and drying methods (fresh, sunlight, oven 60°C, and blower 40°C) for almost all parameters except total a-amino acid content Significant results (p<0.05) were obtained on the drying methods for parameters of crude protein, true protein, in vitro dry matter and protein digestibilities, and mannanase and cellulase activities. There were no significant results between treatments in the crude fiber analysis and soluble nitrogen content Significant results also did not occur between treatment of aerob and anaerob fermentation processes for almost all parameters except for dry matter digestibilities. Results from true protein and in vitro digestibilities show that the fresh fermented product has the best nutritive value, while product dried by sunlight was best among other drying processes. Results from in vivo of protein and energy digestibilities show that there were better metabolizable energy and protein for product with aerobic process and dried with oven and blower treatments, while sunlight drying was best for product processed in anaerobic condition. Although fresh fermented product gave better result from in vitro digestibilities and enzyme activity analyses, for some reasons (easy handling and preservation) sunlight drying gave best results for products processed under anaerobic condition, especially when sunlight drying is cheap.   Key words: Palm oil sludge, fermentation product, Aspergillus niger, thermal drying

Abstract

An experiment was conducted to study the effect of fermented palm oil sludge (PaS) incubated with different ways towards metabolic digestibility on dry matter,true metabolizable energy (TME) and protein digestibilities. A completely randomized design was used. Treatments consisted of unfermented pas (control) and fermented pas with and without enzymatic incubation proces, two levels of incubation temperatures (28°C and 32°C) and three levels of incubation times (3, 4 and 5 days). The digestibility studies were carried out in 46 layer. The results showed that the dry matter digestibility of P_S was not significantly affected by fermentation process neither by incubation times. TME was not affected by fermentation process and incubation times, but it was significantly affected by incubation temperatures during fennentation (P<0,05). Incubation temperatures at 3rC more significant than 28°C. Enzimatic process was more significant than without enzimatic process. True metabolizable energy was highly significantly affected by enzimatic process (P<O,OI). Protein digestibility was highly significantly affected by time and incubation process (P<O,Ol), but not significantly affected by temperatures incubation. It was concluded that fermentation process could improve the digestibility of palm oil sludge (paS). The best result obtained from incubation at 32°C for 3 days and continued by enzimatic process.   Key words: Fennentation, nutritive value, palm oil sludge

Abstract

Palm oil sludge a by product of palm oil industry is not commonly used in poultry feed due to some limiting factors such as low protein and amino acids content and high fiber content. These limiting factors were expected to be reduced by fermentation technology. Therefore an experiment was conducted to study the use of fermented (FLS) and non-fermented palm oil sludge (LS) for broiler chicken feed. Two hundred and ten day-old broiler chicks were used for this study. The birds were allocated into 35 cages with 6 birds in each cage. Each 5 group of birds were fed with one of 7 experimental diets. All diets were formulated with similar nutrient contents containing either LS or FLS at 3 different levels (5, 10 and 15%) and a control diet with no LS or FLS. The experimental diets were fed for 6 weeks and the performances were observed. Carcass yield, abdominal fat, weight of liver and gizzard were also measured at the end of the trial. The results showed that LS or FLS can be included in broiler’s diet, since the mortality, carcass yield, abdominal fat, liver and gizzard were not significantly affected. Best level inclusion of LS was 5%. Although inclusion of 10-15% LS did not affect growth and feed conversion significantly, the feed intake was significantly depressed. The best level inclusion of FLS was 10%, since higher level (15%) caused growth depression.   Key words: Palm oil sludge, fermentation, broilers

Abstract

An experiment was conducted to evaluate the effect of supplementation effect of dried and fresh Aloe vera barbadens gels in broiler feed. 180 heads of one –day-old chickens were randomly allocated into 6 treatments, namely : (1) basal ration (BR) + 0,25 g dried gel of Aloe vera (DGAV)/kg ration, (2) BR + 0,50 g DGAV/kg ration, (3) BR + 1,00 g DGAV/kg ration, (4) BR + 25 g fresh gel of Aloe vera (FGAV)/kg ration, (5) BR + 50 g FGAV/kg ration, (6) BR + 100 g FGAV/kg ration. Each treatment was replicated 5 times and consisted of 6 chickens. Feed intake, weight gain, feed conversion ratio (FCR), percentage of carcass and abdominal fats, and mortality were examined. Data were analized by the complete randomized factorial design 2x3, except for data of FCR , which was descriptively analyzed. Result showed that feed intake and weight gain of broilers were not significantly affected by the physical form of A. vera gel. FCR based on live weight and the carcass of chickens feed by DGAV was better than chickens feed by FGAV. Dosses and physical form of A.Vera gel in ration did not significantly (P>0.05) affect the percentage of carcass and abdominal fat, and broiler’s  mortality, for 5 weeks of observation.
