The quil met nd egg re preferred over oer species due to its etter nutritionl nd medicinl vlue. Quil met is delicious nd tender wi unique tste hving mouwtering deliccy. Importnce of quil production incresed dy-to-dy due to its erly sexul mturity, rpid grow rte, short genertion intervl nd smller ody size, which results in lower spce nd feed requirement. NRC [2] recommended 24% CP nd 2900 kcl ME/kg for growing Jpnese quils. Quils fed on diets wi 27 nd 24% CP t constnt level of energy (2800 Kcl ME/kg) during strter nd grower phses hd more ody weight (BW) t 5 weeks of ge compred to diet wi 20% CP [3]. Hynkov et l [4] lso reported t Jpnese quil fed on diets wi 26 nd 21% CP hd performed well during 1-21 dys nd dys of ge. Higher feed conversion nd grow rte were otined y feeding 23.23% CP wi MJ ME/kg during 0-5 weeks of ge [5]. During e recent yers, e met production performnce of Jpnese quil ws improved y genetic selection. The white strin of Runjun Dowrh nd A. P. S.

Mterils nd Meods: Jpnese quils were fed wi nine diets consisting of ree levels of energy (2600, 2800 nd 3000; 2800, 2900 nd 3000 Kcl ME/kg) nd protein (23, 25 nd 27; 18, 20 nd 22% CP) during strter nd finisher phses, respectively, in 3 3 fctoril design. Results: Protein nd energy individully hd no influence on finl ody weight (FBW) nd weight gin, while feed efficiency ws significntly incresed. The protein energy interction hd significnt effect on grow nd nutrient utiliztion during o strter nd finisher phses. Conclusion: The grow performnce ws higher in quils fed on high protein-high energy (HP- HE) comintion (27% CP nd 3000 Kcl ME/kg) nd medium protein-high energy (MP-HE) comintion (20% CP nd 3000 Kcl ME/kg) during strter nd finisher phse, respectively in utumn seson.

Experimentl design: A totl of 350 dy old chicks were rered under ttery rooder up to one weeks of ge y feeding stndrd (27% CP wi 2900 ME Kcl/kg) chick rtion. Chicks were wing nded for identifiction on 5 dy. On 7 dy, chicks were weighed individully nd distriuted rndomly into 9 groups hving ree replictes of 10 in ech, fter discrding too light nd too hevy chicks. The irds were rered on 3-tier colony cges until 5 weeks of ge. Proper ventiltion nd light were provided roughout e dy. Fresh feed nd clen wter were offered d liitum roughout e experimentl period.

Discussion Improper level of energy leds to restriction of feed intke which lso lower protein intke t might induce mino cid deficiencies cusing negtive effect on performnce. Agin protein hs e highest het increment mongst dietry nutrients, erefore, low protein diet recommended on het stressed roilers [11]. Effect of different levels of protein nd energy on grow performnce nd nutrient utiliztion were studied in roiler quils. Effect of protein: Jpnese quil required dietry protein level of 26 to 27% CP during initil phse of grow (5-27 dys of ge) for optimum weight gin nd feed efficiency [12, 13]. Similrly, Rjini nd Nrhri [14] lso recommended t dietry protein level of 28% nd 20% irrespective of energy level during strter nd finisher phse hd etter < grow rte nd feed efficiency.the positive effect of higher dietry level of protein on grow performnce of quil ws otined only up to strter phse [15, 16, 17]. FCR significntly etter t high protein level which remined sttisticlly similr t medium (22% CP) nd low (20% CP) protein level during 0-28 dys of ge [18]. Wheres, non-significnt differences were oserved on gin in weight, feed intke nd feed efficiency t different (23 nd 25% CP) levels of protein t 5 weeks of ge [19, 20]. Krlp et l. [21] lso reported t PER decresed wi higher levels of crude protein in e diet (20-24% CP). Effect of energy: The improvement of gin in weight nd FCR t highest level of energy could e due to e use of ft to increse e energy level nd e increment of digestiility of nutrients. Wi decrese of dietry energy e feed intke increses due to compenste energy intke [22]. Elngovn et l [23, 24] reported t ody weight gin ws significntly higher in e diet wi 2900 nd 2700 Kcl ME/kg n 2500 Kcl ME/kg diet. While, CCR remined sme t vrious level of energy during 4-7 weeks of ge [25]. Protein Energy interction: An interction existed in weight gin etween energy nd protein s lest weight gin oserved in o ME (12.13 nd 13.39) fed groups wi low CP diet [26]. Significntly 0.01) higher gin in weight nd etter FCR ws oserved y supplementing highest level of protein nd energy comintion (27% CP wi 3200 Kcl ME/kg) [13, 27]. Wheres, Shrivstv et l. [28] recommended 27% crude protein nd 2800 kcl ME/kg for e quil up to 2 weeks of ge nd 24% CP wi e sme energy level from 3 to 5 weeks of ge in dry tropicl climte. Better utiliztion of dietry protein wi respect to energy intke results highest 0.01) N-retention t MP-HE ws in greement of results otined y Kur et l. [5] in quils fed different energy nd protein or EAA comintion.wi increse of live weight gin might e incresed minerl lnce s most of e enzymes relted to protein nd energy metolism re minerl dependent [29]. Conclusion The results of e present study indicted t white plumge Jpnese quils performed well t 27 nd 20% CP wi 3000 Kcl ME/kg diet during strter nd finisher phse, respectively in utumn seson. The digestiility of proximte constituents nd mjor minerls (C nd P) lnce were higher t 20% CPnd 3000 Kcl ME/kg during e finisher phse.
