Production Performance
Results on feed intake, BW gain (BWG), and FCR
are given in Table 5. Feed conversion ratio in birds
supplemented with 5 mg/kg of organic zinc was significantly
higher (P < 0.05) compared with all other
dietary treatments and was caused by a numerical increase
in feed intake. Feed intake and BWG were not
significantly affected (P > 0.05) by dietary zinc source
and dose level. Feed intake from d 3 to 21 varied between
1,215 to 1,281 g/bird and BWG varied between
847 and 878 among dietary treatments. The unsupplemented
control group performed relatively well. Only
