This study
investigated the effect of fermented protein supplementary feed (FPS; 630 g CP/
kg DM, Integro®) as a protein source in broiler diets on performance and relative
weight of carcass and non-carcass components. A total of 600 one-day-old
broiler chickens (ROSS308) were randomly divided into six groups of five
replicates of 20 chicks each in a completely randomized design. During the
experiment (40 days), animals in the control group were fed standard broiler
starter and grower diets (C), while the diets of the other groups were
supplemented with 20 (FPS20), 40 (FPS40), 60 (FPS60), 80 (FPS80) or 100
(FPS100) g/kg FPS. The FPS20 birds had the highest body weight. Both the C and
FPS20 groups had higher feed intake than the other groups. The FCR values of
the FPS20 and FPS40 groups were better than those of the FPS60 and C group,
followed by the FPS80 and FPS100 groups, respectively. The carcass yield and pectoralis major were lower in the FPS80
and FPS100 groups compared to the other groups. The neck weight was higher in
FPS60 and FPS100 than in FPS80 birds. The tail weight was higher in FPS40 and
FPS80 birds than in the group C. The liver weight was higher in the FPS100
group compared to the group C. The whole gut-weight was higher in the FPS40,
FPS80, and FPS100 groups compared to the other groups. These results provide
clear evidence of the benefits of adding 40 g/kg FPS to broiler diets without
any negative impact on growth performance.
