Abstract

Inclusion of palm kernel cake (PKC) in poultry feed is limited due to shell contamination and its low nutritive values, despite the increase of PKC production. Therefore, a series of experiment was conducted in order to improve nutritive values of palm kernel cake (PKC) by sieving and enzyme supplementation. First experiment was designed to reduce shell content using shiever with different diameters (1, 2 and 4 mm). Shell content was measured manually to determine the effect of the sieving. The second experiment was carried out by blowing the after sieving at 2 mm shieve PKC, to produced heavy, medium and light fractions. The shell content and nutrient contents of the medium and light fractions were compared to those of unsieved PKC. In the third experiment, the sieved PKC was supplemented with 2 enzymes with different concentrations, i.e., BS4 at 10, 15 and 20 ml/kg PKC and a commercial multi enzymes at 0.5, 1.0 and 2.0 g/kg PKC. Digestibility of nutrients (dry matter, crude protein and TME) were measured by force feeding method with six replications for each sample. Results of the study showed that sieving with 2 mm diameter siever without blowing was effective in reducing  about 50% of PKC shell and improved crude protein, ether extract and amino acids, contents and reduced the crude fiber content of the PKC. Supplementation of enzymes improved the digestibility of dry matter, crude protein and the true metabolisable energy (TME) of the PKC. Optimum improvement was obtained when PKC was supplemented with 20 ml BS4 enzymes/kg PKC. Similar improvement was obtained by supplementation of commercial multi enzymes at 2 g/kg PKC. Therefore, in order to improve the nutritive values of PKC, it is suggested  to sieve the PKC followed by supplementation of enzyme prior to feeding.

Abstract

Cassava peel which is not used during cassava starch extraction is one of potential resources for animal feed. However, cassava peel has low level protein content, high level crude fiber, and high level of toxic cyanogenic compound. These problems limit the utilization of cassava peel as feed. Solid substrate fermentation using mold may be a solution process to increase its nutritional value and decrease toxic level of cassava peel. In this paper, matters that related with cassava peel fermentation process are subsequently described, namely: (i) problems of cassava peel; (ii) biodegradation and detoxification process; (iii) solid state fermentation methods on cassava peel; (iv) nutritional quality of fermented cassava peel; and (v) application of fermented cassava peel in poultry feed. The fermented cassava peel application is compared with those of cassava root and waste (onggok). Addition of nitrogen inorganic in the fermentation process increases the mold growth and protein content of the product, while fiber and cyanogenic contents are decreased due to mold degradation activity. The fermentation process may be carried out using only the cassava peel as the substrate or mixed with wheat flour, using indigenous microbes, Aspergillus niger or a white rot fungus, Panus tigrinus as inoculum. As well as fermented cassava root and waste, fermented cassava peel can be used to substitute maize as poultry feed, although it is reported that the optimum substitution in broiler ration is only 10%.
