| dc.description.abstract | The objective of this experiment was to study the effect of feeding prognun of crossbreed kedu chicken and arab chicken base on different level of energy and protein in the diet Sixty day old chicken (DOC) were used in this experiment, This experiment consist of three treatment, there are 1'1= diet with energy-protein ratio 145 (EM = 2800kcal/kgandcrude protein ==19.62%(Rl) for1-8:weeksperiod offeeding,1'2= diet with energy-protein ratio 145 for first 4 weeks period of feeding and then continue to fed the diet with energy-protein ratio 150 (EM ='2600 kcal/kg and crude protein == 17.57% (R2» for the second 4 weeks and 1'3 == diet with energy-protein . ratio 145 for first 4 weeks period of feeding and then continue to fed the diet with energy-protein ratio 156 (EM == 2400 kcal/kg and crude protein 15,94% (R3». The .liets and water were given ad libitum. The experimental design used in this study was Completely Randomized Design with 3 treatment and.3 replicates. The data were analyzed by ANOVA (Analysis of Variance). If the result gave significant difference, analysis was continued by Orthogonal Contrast and Polynomial Orthogonal test. The results showed that body weightgain and feed conversion of treatment Pl significandy better than other treatments. Body weight gain of treatment PI, 1'2 and 1'3 were 81.9,72.4,68.9 gram/bird, respectively, Feed conversion of treatment PI, 1'2 and 1'3 were 2.9, 3.3, 3.5 respectively. In conclusion feeding program for crossbreed kcdu chicken and "tab chicken was not necessan' to change energy-protein ratio in 4-8 weeks period of feeding. | id |
