Suitable stock for commercial egg production

For commercial production of eggs local native birds as well as pure breeds of exotic origin such as White Leg Horn, Rhode Island Red etc are not
Egg production of commercial hybrid layers are significantly higher than the pure breeds and hence are used for commercial egg
Some of such hybrid layers named below are recommended: (a) Babcock (b) B V 300 (c) B V 380 (d) H & N (e) Keystone golden
These hybrid layers are marketed by various agencies in Assam and are available as day-old-chicks.

Qualities of day old chicks

Chicks should be cleanly
Chicks should have well dried
Chicks should not have pasted up
They should have round bright eyes and should be alert and
Chicks should be free from unhealed
They should not have any kind of deformities such as crooked leg, defective head or eyes or cross

System of rearing

Intensive system of rearing poultry is of 2 types. They are deep litter system and cage rearing system of which later one is modern system of commercial layer

In deep litter system birds are reared on the floor by putting 3 to 4 inches of bedding material which is called litter. Paddy husk is generally used as litter material in Assam owing to its easy However, substances like wood shavings, straw, ground nut shell, pea shells etc can also be used as litter material.

MANAGEMENT OF CHICK (0-8 weeks)

Preparation of the house

At first the house should be completely depopulated. An approved insecticide like Malathion or Sevin to be used in accordance with the manufacturer’s direction and sprayed inside and at least 3 meters (10 ft) outside the house. This should be done within 24 hours after the bird’s removal and prior to the removal of litters and
After about 48 hours all the equipments and litter should be taken out. Litter should be removed in closed bags and should be taken away from farm premises. The entire house should be cleaned thoroughly. The cleaning process includes scrubbing with brushes until the surface are visibly clean and flushing with clean water. Entire floor and the lower parts of the walls should be soaked and brushed with a detergent powder and scrubbed with hot water. While cleaning, due care should be given to the cracks and crevices of the
When the building is completely dried the entire inside of the shed should be washed down with an effective disinfectant applied with high pressure sprayer. A solution containing 3-5 % cresol or 2-3% caustic soda or lime water can be used as a Disinfection of a shed implies the elimination from the house of all micro-organisms that are capable of causing disease.
All equipment like feeders, waterers etc should be soaked thoroughly, scrubbed free of all adhering matters with a stiff brush, rinsed and sprayed with disinfecting solution. After cleaning, the equipments should be sun dried for a whole
A fresh coat of white wash to the entire inside walls is also considered essential.
New litter should be sprayed over the house and all the cleaned equipments should be returned to the
A foot-bath containing a strong disinfectant should be provided at the entrance of the
The house thus prepared should be kept locked till 2 days prior to arrival of chicks. No other person except the workers of the shed should be allowed to enter the

Preparation for brooding

The floor of the house should be completely covered with new litter material to a depth of approximately 5 cm (2 inch).
Arrangement for brooding should be done in the middle of the area, of the pen, leaving the end of the house unused. The area should be first covered with clean dried gunny bags over which newspapers are to be This is done to prevent the chicks from eating the litter material.
The brooder is placed on the spreaded newspaper. Generally 6 numbers of 40 watt bulbs are used in the
The corners of the brooding room or pen should be rounded off with card board. This is done to prevent the birds from pilling up in the corners after the removal of the chick
To maintain the room temperature of the building, the nets of the sidewalls should be covered with curtains made of gunny bags or Hessian cloth hanged from During the coolest part of the year a plastic curtain may also be used from inside the house in addition to the curtains used from outside of the building. Curtains should be fixed in such a way that it can be rolled back whenever felt necessary.
At least 12 hours before the arrival of chicks all the switches of the brooder and the house should be put on to maintain the required temperature of 95⁰ F(35^o C). This can be measured by putting a thermometer at the edge of the brooder 5 cm (2 inches) above the
A few hours before the chicks arrival the waterers should be filled so that it will be of room temperature when the chicks arrive. The water should be boiled and cooled and mixed with glucose and vitamin. It is essential to provide 3 chick waterers for each 100 chicks for first 2

Providing first feed to chicks

Feeds should be provided at least 2 hours after the chicks are placed in the brooder. The feed should be sprinkled over the entire area covered by newspaper and encircled by the chick After a few hours, feed should be given in flat type feeder lids or clean egg trays.

Requirements of brooding

Temperature: For the first few weeks chicks require artificial warmth until they are well

Temperature requirements for brooding chicks

Age in days/weeks	Brooding temperature
0-7 days/1^st week	95 ^o F(35.0 ⁰ C)
8-14 days/2^nd week	90 ^o F(32.2 ⁰C)
15-21 days/3^rd week	85 ^o F(29.4 ⁰ C)
22-28 days/4^th week	80 ^o F(25.6 ⁰C)
29-35 days/5^th week	75 ^o F(23.9 ⁰C)

Ventilation: Good ventilation is needed to bring in fresh air and to remove carbon-di-oxide, ammonia fumes and other harmful gases, to control the moisture level in the house, to regulate temperature and to help in controlling various diseases.
Litter: The litter is used as a bedding material which is needed mainly to give comfort to the birds. A good quality litter serves as an insulator in maintaining uniform temperature and also acts as a kind of buffer during the summer or winter. Litter also act as a blotter by absorbing the liquid portion of the faeces and at the same time allows evaporative loss of moisture to the air. Further litter acts as a cushion and bird can pick up some vitamins and unidentified growth factors from the

Feeding

Feeding of chicks:

The chicks are provided with a type of feed called chick feed from day-old age to the end of 8^th week of age. It contains about 22 percent crude protein and about 2700 kilocalorie metabolizable
During the first few weeks, it is advisable to put feed in the feeders at least 4 times a Feeders should be cleaned from litter materials before filling it and while placing new feed in the feeders, it should be mixed up thoroughly with the left over feed. At the start, the feeders must be kept full so as to encourage the chicks to eat. Subsequently, the level of feed in the feeder must not be more than half full.
During this 8 week period each chick should be provided with 5 cm (2 inch) feeder space and 5 cm (1 inch) water space.
Placement of feeders at proper height is essential for the chicks to eat properly.
Feeders should be distributed uniformly so that whatever the position of the bird in the house it is not far away from the source of feed. This is especially important during the early days of chick’s
During the brooding period feeders should not be arranged directly under the heat After the removal of the brooder the feeders should be arranged parallel to the rays of natural light falling in the house to avoid producing shadows.
Before putting new feed in a feeder, one end of the feeder should be lifted, preferably the end far away from light so that all the left over feeds goes to the end near the
Inadequate number of feeders in a chick house may cause crowding and spillage of feed. It is also essential to maintain the feeder height, throughout the raising

Watering chicks

The following are some important points, which farmers should remember while watering chicks

Mortality of chicks can be reduced by using boiled and cooled water throughout their brooding period or at least up to first 4 weeks of their
At no stage waterers should be allowed to become dry. Lack of water in a shed for a few hours can slow down the growth rate of the
Availability of drinking surface is more important than amount of water in Hence, several small waterers are better than a few large ones.
Waterers should be changed to bigger ones as the birds
Waterers should be placed in such a way that at no stage birds have to walk more than 3 meters (10 ft) to a waterer. The maximum distance between two waterers should be 2,5 meter (8 ft)
Placing waterer at the same site cause wet spots around the waterers and may result disease outbreak. Hence, waterers should be placed daily at different
Fresh water should be used always. Left over in waterers should be discarded.
All the waterers must be washed nicely with a detergent powder daily in the morning before filling Waterers should be refilled in the afternoon.

Light management for chicks

For better growth and survivability chicks require adequate amount of
The word light implies to both the natural sunlight and artificial electric
Proper management of light in a flock of chicks ensures the following:
Chicks learn to eat and drink
Helps in maintaining the proper growth
Increases feed conversion
Cannibalism can be
Mortality of chicks particularly during the first week of brooding can be kept at minimum.
For the first 48 hours after receiving the chicks all night continuous light of bright intensity should be provided to the
From 3^rd day onwards chicks should be provided with 23 hours of continuous light with one hour of
One hour of darkness will favour better growth and give the bird an experience of darkness to avoid panic during power failure. This one hour of darkness is given generally after the During this period all the lights of inside and outside the sheds must be put off. The lights are turned on one hour after total darkness and kept until dawn.

Debeaking

The trimming of the upper beak of a chicken is known as debeaking which is done to contain cannibalism in a
It is done by cutting and cauterizing the upper beak of the bird at the point half way between the tip of the beak and the nasal
To debeak a bird electrically operated equipment named debeaker is
First debeaking is done at 7 to 10 days of
This is to be repeated at the age between 12 to 14 weeks of age

MANAGEMENT OF GROWERS (9-20 weeks)

Feeding and watering:

During this period they are given a special kind of feed known as grower feed which have about 16 percent crude
The floor space requirement for each bird ranges from 0.111 to 0.139 sq meter (1.2 to 1.5 sq ft) during the grower
Longitudinal/ hanging feeders of large size should be used for providing feed to grower birds.
During this period the feeder space for each bird should be 5 cm 92.6 inch.
For the initial few weeks growers should be provided water with automatic or pan and grill type of

Deworming:

The growers need to be dewormed once in every month with drugs like Piperzine, Albomar, Levamisole, In this regard expert opinion for the local veterinarian should be taken.

Litter management:

In the management of litter, the objective should be to maintain a moisture content of 20 to 30 per
Dampness causes wet litter, soiled plumage, breast blisters and excessive liberation of ammonia
Stirring of litter everyday prevents caking This is done generally after the 2 week of age. Caked litter if noticed should be removed immediately.
When the litter gets moist due to humidity in the rainy season, super phosphate may be mixed at the rate of 1 kg per 3 sq meters (100 sq ft).

Selection of pullets:

The best of the pullets should be selected for egg

The pullets should be uniform in size and
Pullets with morphological defects such as lameness, blindness, emaciated etc should not be selected for transferring them to layer

Transfer of pullets to the layer house:

Pullets should be transferred to layer house before
Birds should be transferred at the age of 16-17^th weeks, so that the stress period will be over by the time they start producing eggs at 20^th weeks of

MANAGEMENT OF LAYERS (21 -72 weeks)

Chickens at the point of laying is known as pullet.
Present day hybrid chicks starts laying from 19-20 weeks of age and continue laying for a period of one year or
For each bird 2.5 sq ft of floor space is

Preparation of the house:

The house should be cleaned and disinfected before and should be made ready well ahead of pullets
The feeders and waterers should be placed well before the arrival of pullets. In case of laying flock hanging feeders are
For every 25 birds there should be one large size hanging
The laying nest should be placed 7-10 days before the onset of egg production.
For every 4-5 birds there should be one laying nest. The nests should be placed by the side of the walls at about 30cm (1ft) above the floor
Litter material or paddy husks should be placed inside the box, so that eggs do not break while being

Feeding and watering of layers:

Pullets should not be given layer feed till they attain 5 % egg
The birds should be give feed twice a
Each bird requires about 110 to 115 gms of feed per day in case of whiter For brown eggers the feed requirement is 120-125 gms per day per layer.
Birds should be provided with fresh drinking water every
It may be noted that layers drink 3-4 times more water than the feed they consume per

Lighting:

There exists positive relation between light hours provided to bird and their egg
Lighting should be increased gradually from 20^th week i.e. on set of egg production till it reaches 16 hours per day and maintained at that level thereafter.
The bulb should be fixed at 8 feet above the floor and good reflectors should be used to direct all light to the bird areas. The bulbs should be checked and cleaned

Collection of eggs:

Eggs should be collected 4 times in a
The first collection to be done at 9 AM followed by 12 AM, 2 PM and lastly at 4
Eggs should be collected in egg trays or bamboo made

Culling of poor layers:

Culling is the procedure of selection and rejection of unproductive and poor producers.
Poor layers should be culled to minimize the cost of production. By doing so farmer can save some amount of money for not needing to buy feed for the non-layers
The characters that should be taken into consideration for distinguishing good and poor layers are as
Appearance: The healthy bird is more active, more alert, vigorous, well fleshed but not fatty, tight feathering with tail and wings carried up. Deviation of any of these characteristics is the indication of poor layers
Moulting: Moulting provides an indication about the laying capacity of a

It is natural and physiological process to renew old feathers at the end of first year of laying. Early moulters are usually poor layers, whereas late moulters are usually good layers.

Broodiness: There may be a few broody birds in a A broody bird will sit in the nest box but will not come out unless forced. They are non-layers and thus cullable.
