This paper gives the effect of application of none
extruded corn meal (T1, T2) and extruded corn meal (T3, T4) in broiler
chicken nutrition. In meals the corn grain (C) was replaced by corn meal
in the amount of 50% (T2, T4) and 100 % (T1, T3). The experiment lasted
42 days in system 5 × 4 (5 treatments × 4 repetitions). In every
treatment 300 chickens were included. Feeding of chicken was ad libitum,
with three types of meals: starter with 23.30 % CP and 12.78 MJ/kg ME;
grower with 20.30 % CP and 13.10 MJ/kg ME, and finisher 17.70 % CP and
13.25 MJ/kg ME. The results of
investigation were body weight of chicken C – 2161 g, T1 – 2168 g, T2 –
2164 g, T3 – 2261 g, and T4 – 2244 g; daily growth C – 51.45 g, T1 –
51.62 g, T2 – 51.52 g, T3 – 53.84 g, and T4 – 53.43 g; mortality of
chicken C – 5.00 %, T1 – 5.71 %, T2 – 3.64 %, T3 – 3.81 %, and T4 – 6.36
%; feed conversion ratio C – 1.93 kg/kg, T1 – 1.84 kg/kg, T2 – 1.84
kg/kg, T3 – 1.86 kg/kg, and T4 – 1.84 kg/kg. Differences in production
parameters were not statistically significant, except differences in
body weights between the group T3 and T1, T2 and K groups which were
statistically significant (P < 0.001) and between T4 and T1, T2 and C
were statistically significant (P < 0.001). Processing percentages
were unified among groups with minimal differences in contents of
abdominal fat in carcass. There were only statistically significant (P
< 0.05) differences in the abdominal fat between the groups of males
and females T1 and T2 and all other groups.
