A total of 900 recently hatched chicks from prior incubated eggs were randomly divided into 5 Patio strategies i.e., Treatment 0 included chicks without any feed and water in hatcher, Treatment 1 included offering feed and water during the last three days in hatcher, Treatment 3 included birds kept for extra 3 days in hatcher with feed and water, Treatment 5 included keeping chicks for extra 5 days in hatcher with feed and water and Treatment 7 included birds kept for extra 7 days in hatcher and offered feed and water at same place. Chicks hatched in each tray were further subdivided into 3 groups and subjected to three dietary treatments including (0.3 g/kg Neomycin, 0.1 g/kg Protexin and Control group) with 3 replicates of 20 birds each. At the age of five and seven weeks six birds (3 males and 3 females) from each replicate; hence a total of 90 birds were slaughtered to study different parameters pertaining to morphometric measurements, carcass and slaughter characteristics. At the end of the experiment, the data were analyzed according to Completely Randomized Design (CRD) under factorial arrangement using GLM (General Linear Model) procedures (Steel et al. 1997). Comparison of means was worked out through Duncan’s Multiple Range test with the help of SAS 9.1. (2002-2004). Result of present study showed significant differences among different patio strategies and growth promoters in different parameters at 5 and 7 week of age. Breast width, drumstick circumference, liver % Heart%, Bursa% and pancreas% were found to be significantly higher in birds kept under patio system for 0 days at the age of 5th week. Keel length, Breast %, neck %, head% and ovary % were found to be higher in birds kept under patio system for 1 day at the age of 5th week. Shank circumference and testes % were found to be higher in birds kept under patio system for 5 day at the age of 5th week. However Body length, drumstick length, shank length, wing spread, fillets%, thymus%, and spleen%, were found to be higher in birds kept under patio system for 7 day. The most promising result in terms of growth performance and carcass characteristic were observed in birds kept under patio system for 3 days at the age of 5th week. Under patio system 3 highest body weight, carcass % Wing %, back%, drumstick %, shank %, and gizzard % were observed. Breast width, breast %,drumstick circumference, shank length, shank circumference, keel length, wing spread, thigh %, back %,head % ,heart %,% thymus% ,spleen %, and pancreas % were found to be higher in male birds. Body length, body weight Carcass %, Shank %, shank circumference, drumstick length, wing %, fillets%, drumstick %, neck%, liver %, and bursa % were found to be higher in female birds. Body weight, Fillets%, breast %, liver %, shank % and heart % were found to be higher in birds supplemented with probiotic diet. Breast width, drumstick length, keel length, shank length, wingspread, drumstick %, back %, head %, gizzard%, spleen%, and bursa%, were found to be higher in birds supplemented with antibiotic diet. Body length, Drumstick circumference, shank circumference, wing%, neck%, carcass%, thymus%, bursa % and pancreas % were found to be higher in birds fed Control diet. Body length, Shank Circumference, Wing spread, and liver % were found to be significantly higher in birds kept under patio system for 0 days at the age of 7th week. Fillets, bursa %, ovary % and testes were found to be higher in birds kept under patio system for 1 day. Breast width, Keel length, thigh %, back%, neck %and spleen % testes were found to be higher in birds kept under patio system for 5 day. However breast %,Head % ,shank %,Heart %,Gizzard % and pancreas % were found to be higher in birds kept under patio system for 7 day. Body weights, carcass %, Drumstick circumference, Drumstick length, shank length, wing %, Drumstick % and thymus % werefound to be higherin birds kept under patio system for 3 days. Breast width, breast %,drumstick circumference, drumstick length, keel length, wing spread, fillets %, thigh %, back %,head % shank %,heart %gizzard% thymus% and pancreas % were found to be higher in male birds. Body length, body weight, Carcass %, Shank length, shank circumference, wing %, drumstick %, neck% liver %, spleen %and bursa % were found to be higher in female birds. Body length, body weight, Wing %, Back %, neck % and ovary % were found to be higher in birds supplemented with probiotic diet.Shank circumference, Shank length, wingspread, Breast %,Head %,liver %,heart %,thymus %,bursa%, pancreas % and tested % were found to be higher in birds supplemented with antibiotic diet.Breast width, Drumstick circumference, drumstick length, keel length, thigh %,drumstick %,carcass %,shank %,gizzard % and spleen % were found to be higher in birds fed Control diet. Conclusions Based upon findings of the present study it can be concluded that: 1. Patio system helped improving body measurement (body weight, breast width, body length, drumstick length, keel length, shank length, drumstick and shank circumference and wing spread) in Japanese quail at different week of age. 2. Patio system also had positive effect on carcass %. 3. The use of probiotic at different week of age helped improving body weight and body length in Japanese quail. Suggestions and recommendations No doubt the results of present study are very promising regarding the use of patio systems. However, This is an entirely new approach and unique in the sense that a little work is documented , hence needs to be studied very thoroughly. 1. It is suggested that the use of different probiotics and antibiotics needs to be studied in as much details as possible to draw some solid conclusions and guidelines for the quail industry regarding the use of these products. 2. In addition, females quail produced superior mean values in live body weight, body length and carcass % than males. So, more female quails be raised and produced by using these strategies.

2. Patio system also had positive effect on carcass %.
3. The use of probiotic at different week of age helped improving body weight and body length in Japanese quail.
Suggestions and recommendations
No doubt the results of present study are very promising regarding the use of patio systems. However, This is an entirely new approach and unique in the sense that a little work is documented , hence needs to be studied very thoroughly.
1. It is suggested that the use of different probiotics and antibiotics needs to be studied in as much details as possible to draw some solid conclusions and guidelines for the quail industry regarding the use of these products.
2. In addition, females quail produced superior mean values in live body weight, body length and carcass % than males. So, more female quails be raised and produced by using these strategies.
