Effect of feeding fermented and non-fermented palm kernel cake on the performance of broiler chickens: a review

SUMMARYPalm kernel cake (PKC) is a by-product of oil extraction from palm fruits and has been included in poultry diets as an alternative to soybean meal yellow corn. Due its high content fibre, coarse texture gritty appearance, the use PKC nutrition limited. In order increase nutritive value PKC, there tendency nowadays create solid state fermentation (SSF) by using cellulolytic microbes. This paper reviews impact feeding fermented non-fermented on performance broiler chickens. Recent studies have reported that SSF microorganisms improved PKC. The nutrient digestibility increased significantly Paenibacillus polymyxya ATCC 842 or Weisella confusa SR-17b. availability valine, histidine, methionine arginine was 70.42%, 71.50%, 71.92% 81.15%, respectively, P. polymyxa 842. crude protein (CP) 61.83% 59.90% W. SR-17b, respectively. addition, body weight gain (BWG) feed conversion ratio (FCR) broilers fed 15% compared those (2000.43 g versus 1823.23 1.75 1.91, respectively). intestinal Enterobacteriaceae decreased (4.03 CFU/g) lactic acid bacteria (5.56 birds Therefore, can be diet up 15%, replacing part corn diet, leading decrease overall cost feeding.
