Abstract

Indonesia imports feedstuffs such as corn and soybean meal to fulfill the requirement in the country. The volume of imports is increasing due to the increasing demand on livestock products. On the other hand, we have a huge amount of unconventional feedstuffs produced locally. Palm oil sludge is one of the unconventional feedstuffs that have not been utilized. The palm oil sludge production in 2001 was approximately 632,570 ton and is increasing following the increasing of palm oil productions in Indonesia. Some reports have shown that palm oil sludge could be included in the feed of cattle, sheep, pigs and poultry. The sludge is limited in use for poultry feed due to high fiber contents and low nutrient digestibility. Indonesian Research Institute for Animal Production conducted researches in order to improve nutritive values of palm oil sludge by fermentation method. The fermentation increased the protein, amino acids, metabolisable energy (TME) and reduced the fiber contents of the sludge. Feeding trials showed that the fermented products could be included as much as 10% in diets of broilers and native chickens, but 15% could be included in diet of growing ducks.   Key words: Palm oil sludge, nutritive values, poultry feed, fermentation

Abstract

Inclusion limit of palm oil sludge (POS) in poultry diet varies according to processing, and species or strain of the animal. Therefore, an experiment was conducted to study the utilization of fermented (FPOS) and non-fermented palm oil sludge (POS) for growing drakes. A number of 224 one week-old male ducklings were randomly distributed into 7 dietary treatments, with 4 replicates and 8 ducklings for each replicate. The dietary treatment consists of 2 kinds of feedstuffs (POS and FPOS) with 3 levels (5, 10, and 15%) and one control diet consisting neither POS nor FPOS. All diets were formulated with similar nutrient contents and meet the requirement of growing duckling and fed to 8 weeks old. The results showed that at the first week of the trial, feeding of POS or FPOS significantly (P<0.05) depressed growth of the ducklings, although the feed consumption was higher than the control. However, overall performances (body weight, feed consumption and feed conversion) of the ducklings, carcass yield, liver weight, gizzard weight and abdominal fat weight measured at the end of the trial were not significantly (P>0.05) affected by the dietary treatments. Therefore, it is concluded that it is safe to include POS or FPOS up to 15% in the diet of growing ducklings.   Key words: Palm oil sludge, fermentation, ducks, growth

Abstract

Screening for choosing the best bacterium and mold producing cellulase was carried out from eight xylanolytic bacteria and three cellulolytic molds isolated from termites. Each bacterium and mold was inoculated on the agar medium containing minerals and carboxymethylcellulose. The diameters of colony and clearing zones were measured after stained with Congo red. Four bacteria: Bacillus larvae XB 1-1, B. larvae XU 2-2, Bacillus PU 2-2, and B. pumilus PU 4-2 showing higher clearing zone ratio were further submerged cultured in PM medium containing 2% wheat pollard in the shaker incubator at room temperature, 150 rpm for 36 and 48 hours. The three molds: Aspergillus flavus S 13, MS 21, and Penicillium nalgiovense S 11 were also cultured in the same way as bacteria, but in Mandels medium containing 2% wheat pollard for three and five days incubation time. B. pumilus PU 4-2 and A. flavus S 13 produced the highest CMCase in each group respectively. All enzyme assays of A. flavus S 13 had higher activities than that of B. pumilus PU 4-2. The specific activity of CMCase, avicelase, FPase, and cellobiohidrolase were the highest on the enzyme of A. flavus S 13 produced from 3 days incubation time, while its β- glucosidase was the best for five days incubation. In term of activities, A. flavus S 13 had the highest ability to produce cellulase. The ability of B. pumilus PU 4-2 to produce cellulase and xylanase at the same time was an additional value.   Key words: Bacillus pumilus, Aspergillus flavus, cellulases
