A Research on the Determination of the Requirement Periods of A, D3 and Vitamins E Supplemented to Broiler Rations

Abstract

This research was conducted to determine the requirement periods of A, D3 and E vitamins supplemented broiler rations. The duration of the experiment was 7 weeks and it was carried out with 4 groups. These vitamins were added to the 1 st group's rations for whole experimental period, 2 nd group's rations for first 6 weeks of experimental period, 3 rd group's rations for first 4 weeks of experimental period and to 4 th group's rations for first 2 weeks ofexperimental period as a vitamin premix. According to the results obtained at the end of the research, the average live weights for the experimental groups' were 2158.4, 2161.1, 2125.5 and 2086.3 g P>0.05 ; the average live weight gains were 2111.8, 2115.0, 2079.2 and 2039.7 g P>0.05 ; the average feed consumptions were 3955.0, 3913.6, 3958.0 and 3806.0 g P>0.05 ; the feed conversions were 1.8746, 1.8507, 1.9014 and 1.8672 P>0.05 ; mortalities were 7.8, 5.6, 7.8 and 13.3 % for the 1., 2., 3. and 4. groups respectively. The differences among the experimental groups were insignificant for feed cost of one kg of live weight gain P>0.05
