Yeast and fungi are microorganisms commonly used in
feedstuff fermentation processes. In previous studies, the
fermentation of cassava with Saccharomyces cerevisiae and
Aspergillus niger (A. niger) was found to increase the protein
content from 44 to 109 g/kg, and 44 to 122 g/kg, respectively(Oboh et al., 2002; Oboh and Akindahunsi, 2003). Thongratok
et al. (2010) evaluated the optimal conditions for improving
the protein content of cassava pulp and found that
treating this waste product with Aspergillus oryzae (A.
oryzae) and 7.5 g/kg urea for 4 days can improve the protein
and amino nitrogen content from 25.9 and 8.9 g/kg (unfermented)
to 174 and 151.3 g/kg, respectively.
Accordingly this experiment aimed to study the effect of
fermented cassava pulp (FCP) in broiler diets on the nutrient
digestibility and retention, growth performance and carcass
quality of broilers. In addition, the alanine aminotransferase
(ALT) and aspartate aminotransferase (AST) enzymes were
also measured to be used as an indicator of the toxicity of
urea, which is used as a nitrogen source during the fermentation
of cassava pulp.
