Abstract
The study was conducted to determine the effects of different energy and
protein levels on performance of native chickens in the starter (0-8 weeks) and grower
phase (9-12 weeks). A total of 396 eggs were collected from backyard rearing farmers
and incubated in commercial incubator, 81.5 % fertility, 63.8% TES hatchability and
78.5% FES hatchability was recorded. A total of 200 day old straight run healthy
native chicks were randomly divided into 4 treatment groups and 5 replicates in each
treatment which contained 10 birds each. The experimental diet during starter phase
and grower phase were as per BIS (2007) recommendation for layer which was
control T1, T2 10% less than T1, T3 15% less than T1 and T4 20% less than T1. The
results showed that there was significant (P<0.01) difference in feed intake, body
weight gain and FCR. Final body weight and average daily gain was significantly
(P<0.01) higher in T1 and T2. There was no significant difference in digestibility,
survivability and carcass traits except giblet weight yield. It was concluded that
during starter phase from 0-4 weeks T2 diet (18 % CP; 2520 ME Kcal/kg), from 5-8
weeks T1 diet (20 % CP; 2800 ME Kcal/kg) and during grower phase T1 diet (16 %
CP; 2500 ME Kcal/kg) was optimum for higher performance and economical in
native birds chicken.
