Quail is a collective name for several genera of mid-sized birds in the pheasant family Phasianidae, or in the family Odontophoridae. The quails are small, plump terrestrial birds. They are seed eaters, but will also take insects and similar small prey. They nest on the ground.
Japanese quail and Bobwhite quails are the domesticated varieties of quail. Japanese quails are hardy, grows faster, has a short generation interval and is precocious. The meat is a delicacy. Specific lines developed for egg production as well as meat production are available.
CARE & MANAGEMENT
Japanese quails are hardier. They seldom have disease problems. Therefore, there is no need for routine immunization programme as with other poultry species. One major disease that affects Japanese quail is quail enteritis. This disease can be treated using appropriate antibiotics under Veterinarian’s advice.
Care of Adult Quails
The males and females can be separated based on physical appearance at about 4-5 weeks of age. The males have an even coloured rusty brown breast feathers with only few speckles of white. Where as the females have grey and black speckled breast feathers. The males also have a cloacal gland, which secretes a white foamy material. In contrast to most poultry, females are slightly heavier than males Quails reach sexual maturity at about six weeks of age and weigh 120 g. Adults require 150-180 cm 2 per quail in laying cage. A feeder space of 2-3 cm per quail and water space of 2 cm has to be provided. For laying flock a photoperiod of 16 hours is desirable for good egg production. Layer quails may be provided with a mash containing 22% protein and 2650 K cal/kg of ME. Japanese quails reproduce well in all seasons. The eggs are laid from evening, the peak being between 6.30 – 7.30 p.m. The eggs laid during second year of lay are very much fewer than first year. Quail egg weighs around 10 g and is characterised by a variety of colour pattern ranging from dark brown, blue and white to buff each mottled with black, brown and blue. The egg shell is very thin and therefore breaks easily.
Care of quail chicks
The hatch weight of quail chicks is 6-7 g. They can be brooded either on deep litter or in battery brooders. However brooding the quail chicks in cages up to end of 3 weeks of age reduces initial mortality considerably. The floor space suggested is 75 cm2/chick under the hover and 75 cm2/chick as run space. The brooder temperature recommended is 37oC at the beginning and this should be reduced at 2.7oC per week until the chicks are 4 weeks of age, by which time the quails would have grown their feathers very well. During brooding, water should be given in shallow dishes filled with marbles or pebbles to prevent quail chicks from drowning. The marbles or pebbles can be removed when the chicks are about 2 weeks of age. The feeder space and water space recommendations are 2 and 1 linear cm per quail chick respectively. Quail chicks can be fed with a mash containing 27% protein and 2750 K cal / kg of ME up to end of 3 weeks of age and a mash containing 24% protein and 2750 K cal/kg of ME from 4th week of age. Maximum care has to bestow during the first two weeks of life of quail chicks.
Care of Breeding Quails
Good fertility can be obtained with a male-female ratio of 1:2. After introduction of male to a female flock, fertile eggs can be collected from 4th day onwards. Optimum fertility is obtained when the age of breeding flock is 8 months or less. Hatchability of fertile eggs rapidly declines when eggs are collected from older females. However, this effect is not observed with males.
Feed ration for Japanese Quails
Ingredients-Starter (0-3 weeks) -Grower (4-6 weeks) -Layer (above 6 weeks)
(a) Yellow maize -43.25- 44.25-46.25
(b) Groundnut cake-20.00-20.00-20.00
(c) Soyabean meal-22.00-14.00-10.00
(d) Rice polish-3.00-10.00-8.00
(e) Unsalted dried fish-10.00-10.00-10.00
(f) Mineral mixture-1.50-1.50-1.50
(h) Shell grit-0-0-4.00
For every 100 kg of feed, commercially available vitamin mixture may be added at the rate recommended by the manufacturer
Care of hatching eggs
Shell of quail eggs are comparatively thinner and therefore should be handled carefully. Eggs should be held in an atmosphere free of dust and having a temperature of 14 to 16’C with a relative humidity of 70 to 80%. Eggs held even under these conditions should be used for hatching within 7 days of holding. The incubation period of quail egg is 18 days. Quail eggs can be incubated artificially using forced draft incubator at a temperature of 36.9 – 37.2’C with a relative humidity of 60 to 70%. Eggs should be turned 4 to 6 times daily upto 14 days of incubation.
