CORN MEAL IN BROILER CHICKEN NUTRITION

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 -53.84g, 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.
