Abstract
A biological trail was carried out to optimize the dietary crude protein and energy requirements in TANUVAS Aseel x Nandanam Chicken-4 (ANC4) from day old to 12 weeks of age. A total of 360 day old ANC4 chicks were wing banded, weighed individually and distributed randomly into six treatment groups with three replicates of 20 chicks each per group. The experimental birds were fed with three levels of crude protein (16, 18 and 20 per cent) and two levels of metabolizable energy (2700 and 2800 Kcal/Kg) with ad libitum feeding and watering. Standard managemental practices were adopted throughout the experimental period in deep litter system. Weekly data on body weight, body weight gain, feed consumption, feed conversion ratio, livability, slaughter studies, cut-up-parts, litter pH, moisture, proximate analysis of meat, HI titre and economics were recorded and calculated.
The birds fed with 18 per cent CP and 2800 ME (T5) had higher body weight of 1227.34 ± 24.77 (g) followed by T4 (16:2800) and T1 (16:2700), respectively. Similarly, birds received higher ME of 2800 Kcal/kg had recorded higher body weight of 1205.42 ± 13.46 g followed by 2700 ME group (1145.42 ± 13.46 g). At 12th week the birds received 2700 Kcal ME/kg had less feed consumption (3810.31g) than 2800 Kcal ME/Kg (4183.56 g) fed groups. Whereas, different levels of crude protein had no significant difference in feed consumption. Similarly, the birds received lower CP and lower ME (T1 and T2) had shown numerically better feed conversion ratio (3.21 ± 0.06 and 3.31 ± 0.18). The overall livability was highest (97.10 per cent) in birds fed with 20 per cent CP and 2700 Kcal ME/Kg.
