The effect of different energy-protein ratio in diets on feed digestibility and performance of native chickens in the starter phase
Author(s): Desak Putu Mas Ari Candrawati
Abstract: The present study was conducted to determine the effects of different energy-protein ratio in diets on feed digestibility and performance of native chickens in the starter phase. A total of 128, 1-d-old healthy male native chickens were randomly divided into four treatment diet groups: A) diets containing metabolic energy (ME) 3100 kcal/kg with crude protein (CP) 22%; B): diet containing 3000 kcal/kg ME with CP 20%; C): diets containing ME 2900 kcal/kg with 18% CP (C); and D): diet containing ME 2800 kcal/kg with 16% CP, respectively. There were four replications, resulting in 16pens, which contained 8 birds each. The results showed that there was no significant difference (P>0.05)in feed consumption andfeed digestibility between group treatments. Final body weight and live weight gains, the highest (P<0.05) obtained in birdsGroup A and B, conversely, the lowest was found in Group C and D. FCR between treatments showed significant differences (P<0.05). The highest feed efficiency was found in Groups A and B, on the contrary, the lowest was found in Groups C and D.It can be concluded the decrease of metabolic energy content and protein content in the ration resulted in higher performance of native chickens, but did not affect feed digestibility.
