Production of livestock species with short generation interval could be a viable option in ameliorating shortage of protein among the populace in developing countries like India. Japanese quail is one of the poultry species with very short generation interval, comparatively more resistant to infectious diseases than chicken and it does not require vaccination and relatively low medication required for rearing. Livability is high in Japanese quail compared to other species of poultry. Japanese quail has the advantage of quick returns as they are marketed from 4 weeks of age itself and before attaining sexual maturity i.e., the sixth week. They have high fecundity with a high rate of egg production. Feed conversion ratio in Japanese quail though not equivalent to the commercial broiler, better than other species of poultry. They can be reared with high stocking density. Considering the above benefits and in the current paper we have discussed existing practices in management, production performance of Japanese quail.

Management of Japanese quail
Incubation period for quail eggs is 18 days. Incubation requirement are as follows:
Both floor and battery types of brooding followed in Japanese quail rearing. In floor type of brooding has high mortality due to spraddled legs. Battery type brooding can be done to 3weeks of old. At most care should be taken in the brooding period.
Deep litter system
Six quails can be reared in sq feet of floor space after two weeks, quails can be reared in cages. This will help to gain good body weight.
No wet spots
Animal protein factor supplies to the birds
Litter act as valuable insulating agents.
Battery system rearing
Each unit is about 6 feet in length and one foot in width and subdivided into six subunits. For saving the space, the cages can be arranged up to six tiers in height. There should be 4 to 5 cages in a row. The bottom of the cage is fixed with removable wooden plates to clean the bird droppings. Long narrow feed troughs are placed in front of the cages. Water troughs are placed at the back of the cages. Commercial egg layers are usually housed in colonies of 10-12 birds per cage. For breeding purposes, male quails have introduced in the cages in the ratio of 1:3 females.
Most intensive type and a greater number of birds reared per unit area
Facilitate correct maintenance of records.
Control feed utilization and Production of clean eggs
Control of parasitic infections
Helps in identifying poor yielders or diseased which promote culling
Reproduction in quails
One male to three females for commercial utilization and 1:1 up to 1:3 for research and development
Vent Sexing in quails can be done at the age of 3rd week.
A condition of the abdomen and the distance between pelvic bones gives a fair indication. 1½ finger space between pelvic is an indicator of good layers
Layer quail management
Japanese quail start laying at 6thweek of age. The quail used for the breeding purpose should be reared under restricted feeding and lighting during the growing period to avoid early sexual maturity. Also, it is advisable to rear males and females separately from 3rdweek onwards and are to be fed with separate diets. During laying, the quail layers are provided with 16 hrs total light and hence a minimum of 4 hours extra artificial light is required for maximum egg production.
24 hrs light is required up to 2 wks of age, it may be reduced to 12hrs at the end of 3wk and thereafter 12hrs photoperiod is adequate up to 5wks of age. After about 14-16hrs photoperiod required for layers. Quails lay 75% of daily egg production between 3-6 P.M. 20% of the eggs are laid during night hours. The female starts laying at about 6 wks of age, reach 50% production by 8 wks and peak 80% production is attained by the 10 wks of age. The high yielding quails lay about 260-300 eggs in a year with a total feed intake of about 8 to 12kg. The rate of lay reduces sharply after 26 wks of age.
Japanese quails require about 400 g feed for the production of 12 eggs
Prospects of quail farming
This business is a very lucrative business. Quail bird farming is five times better than chicken and turkey rearing, and a person with 400 quail laying birds is better off than a person with a person with 2000 laying chickens. The demand for commercial quail production is increasing day by day in the country. The following are the reasons.
Quails are the smaller sized bird, so they can be raised within the small place. Minimum floor space requirement i.e, 8-10 quails can be housed in a space required to house one broiler/ layer chick
Quails grow very fast and gain maturity faster than any other poultry birds.Quails need only 40-50 days to become mature and come in production from 45 days of age. On the other hand, chicken needs average 6 months to be mature.
Early marketing age for table delicacy: 5-6 wks.Quail are less susceptible to common diseases.
Low feed requirement 25-30 gm per quail/day.Feed conversion for egg production in Japanese quail is better than in laying hens. Quail hens need less than 2 kg of feed to produce 1 kg of egg while laying hens need between 1.9 to 2.5 kg of feed to make the same amount of egg.
Very prolific because of short generation interval and completes 3-4 generation per year
Quail farming requires less investment to start and provide a quick return from it and also provide higher cost-benefit ration compare to chicken layer farming.
Japanese quail as a laboratory animal
The interest in the Japanese quail as a research animal was greatly increased after 1957 due to groups at the University of California and Auburn University who proposed its value in biomedical research. Fields in which quail is widely utilized include genetics, nutrition, physiology, pathology, embryology, cancer, behavior, and the toxicity of pesticides. Quails are used for laboratory animal for many reasons like require little space and maintenance, adaptable to laboratory conditions, short generation intervals and high fecundity, many specialized strains.
Quail eggs are much richer in vitamin B2, iron, potassium, calcium, and phosphorus than chicken eggs. Quail eggs are rich in HDL cholesterol, (the ‘good' cholesterol), so e
