ABSTRACT
Protease as feed additive is being used in
poultry production as a partial replacement for protein sources for cost
efficiency and reducing nitrogen excretion. However, diverse proteases
may yield different responses under field conditions. A pellet diet study was conducted
in Cobb broilers to assess the impact of
coated compound (CC) and mono-component
(MC)
proteases
with 5% replacement of digestible amino acids and 0.9% crude protein. Birds fed
positive control diet had a better growth than those fed negative control
diet,
regardless of enzyme supplementation. However, CC
protease had shown feed conversion
ratio (FCR) like control in a
reformulated diet, whereas negative control and MC protease missed to gain the feed conversion. In measures of
nutritional efficiency, like energy efficiency, protein efficiency and
amino acids efficiency (lysine and methionine), the CC
protease proved to be better than MC
protease. In terms of European efficiency factor (EEF),
control and CC
protease
elicited
a closer response, whereas the other two groups showed a drop. In this study, CC
protease allowed partial
substitution of digestible amino acids and crude protein, while maintaining
feed efficiency and
animal performance. It could be concluded that incorporating CC
proteases is an efficient choice to maximize the utilization feed material
resources and efficiency in animal protein production.
