Constructing Poultry Pen House
Constructing Poultry Pen House is a free article for you. Actually, Constructing Poultry Pen House For your birds is a setup step for poultry business. Although, Nigerians are enthusiastic and excited about poultry (chicken) farming. Nevertheless, many starters do it with much ignorance of the basic details. There are several common error among some poultry farmers. More especially the backyard farmers. Contact us today lets help you out.
More On Constructing Poultry Pen House
Intuitively, most Nigerian wakes up one day and decides to rear a number of chickens. The first thing they do is to build a house or pen. Especially in their backyard. There are factors to take into account when constructing a chicken pen anywhere. Whether backyard or not.
The Need For A Poultry Pen
Firstly, protect birds from adverse climatic conditions
Secondly, toensure easy and economic operation
Thirdly, toensure scientific feeding in a controlled manner
To facilitate proper micro-climatic conditions in a near vicinity of bird
For effective disease control measures
To ensure proper supervision
Number Of Birds In A Construction Poultry House
The number of chickens to rear is determined by the floor space available for the chicken pen and also by the floor space requirements per chicken at various stages of development in the chicken. Many do not know the minimum floor space requirements per chicken especially in the brooding and laying stages. In error, they overstock or overcrowd the chicken pen. Overcrowding is a hazard with serious negative impact on the fortunes of the business.
Some Basic Guides On Constructing Poultry Pen House
- Firstly, Know the dimensions (length & breadth) of the floor space available
- Know the minimum floor space requirements per bird and work out the occupancy i.e. knowing the maximum number of chickens that the pen can conveniently accommodate.
- Likewise, Know the space requirement at various stages of development of the chicken. If you do not know, please consult a poultry or livestock consultant to advise you. Do not guess.
More On Pen Construction
Are you going to bring in battery cages? The number of chickens determine the number of cages to bring in. What are the dimensions (length & width) of the battery cages to be installed? How many battery cages can the floor space of the chicken house accommodate conveniently? You have to know all the above in before the construction.
Will the chicken pen have inbuilt waste management facilities? Will the land size accommodate the facility? You have to consider all these issues.
Layout Of Poultry Farm
A small size poultry farm doesn’t require any special layout as it involves construction of only one house. The medium and large size farms require special considerations for placement of building in the farm premises.
The Basic Principles To Be Observed For Layout Are;
- Layout should not allow visitors or outside vehicles near the birds.
- Also, the sheds should be so located that the fresh air first passes through the brooder shed, followed by grower and layer sheds. This prevents the spread of diseases from layer houses to brooder house
- There should be a minimum distance of 50-100 feet between chick and grower shed and the distance between grower and layer sheds should be of minimum 100 metre.
- Likewise, the egg store room, office room and the feed store room should be located near entrance to minimize the movement of people around the poultry sheds.
- Lastly, the disposal pit and sick room should be constructed only at the extreme end of the site.
Different Types Of Poultry Houses
- Firstly, Brooder / chick house-It is used to brood and rear egg-type chicks from 0 to 8 weeks of age.
- Secondly, Grower house-It is used to grow egg-type birds from 9 to 18 weeks of age.
- Thirdly, Brooders cum grower house-Here, the birds are reared from 0 to 18 weeks of age (entire brooding and growing period of egg-type chicken).
- Layer house-In which birds over 18 weeks of age are reared, usually up to 72 weeks of age.
- Broiler house-In which broilers are reared up to 6 weeks of age.
- Finally, Breeder house-In which both male and female breeders are maintained at appropriate sex ratio.
Note; Environmentally controlled (EC) house-In which, entire environment is manipulated in such a way that is optimum for the bird’s growth.
Optimal Environmental Conditions For Rearing Broilers
- Temperature – 22-300C (70-850F)
- Relative Humidity – 30-60 %
- Ammonia level – Less than 25 ppm
- Litter moisture – 15-25%
- Air flow – 10-30 metres/minute
House Orientation (Direction)
The poultry house should be located in such a way that long axis is in east-west direction. This will prevent the direct sunshine over the birds.
Each broiler require one square foot of floor space while a layer requires two square feet of floor space under deep-litter system of rearing. So the size of the house depends on the number of birds to be reared.
Furthermore, the length of the house can be of any extent. The number of birds reared and availability of the land determines the length of poultry house.
The open sided poultry houses in tropical countries should have a width not more than 22 to 25 feet in order to allow ample ventilation and aeration at the mid-portion. Sheds wider than this will not provide adequate ventilation during the hot weather.
If the width of the shed is more than 25 feet, ridge ventilation at the middle line of the roof top with proper overhang is a must. Hot air and obnoxious gases which are lighter than air move upward and escape through ridge ventilation. In environmentally controlled poultry houses, the width of the house may be even 40 feet or more since the ventilation is controlled with the help of exhaust fans.
Similarly, the height of the sides from foundation to the roof line should be 6 to 7 feet (eaves height) and at the centre 10 to 12 feet. In case of cage houses, the height is decided by the type of cage arrangements (3 tier or 4 tier).
Good foundation is essential to prevent seepage of water into the poultry sheds. The foundation of the house should of concrete with 1 to 1.5 feet below the surface and 1 to 1.5 feet above the ground level.
Also, the floor should be made of concrete with rat proof device and free from dampness. The floor of the house should be extended 1.5 feet outside the wall on all sides to prevent rat and snake problems.
The door must be open outside in case of deep-litter poultry houses. The size of door is preferably 6 x 2.5 feet. At the entry, a foot bath should be constructed to fill with a disinfectant.
Also, the side wall should be of 1-1.5 feet height, and generally at the level of bird’s back height. This side wall protects the bird during rainy days or chill climate and also provides sufficient ventilation. In case of cage houses, no side wall is needed.
Roof of the poultry house may be thatched, tiled, asbestos or concrete one depending upon the cost involvement. Different types of roofs are Shed, Gable, half-monitor, full-monitor (Monitor), Flat concrete, Gambrel, Gothic etc. Gable type is mostly preferred in tropical countries like India.
The overhang of the roof should not be less than 3.5 feet in order to prevent the entry of rain water into the shed.
Light should be provided at 7-8 feet above the ground level and must be hanged from ceiling. If incandescent bulbs are used, the interval between two bulbs is 10 feet. In case of fluorescent lights (tube lights) the interval is 15 feet.
Systems of Poultry Housing
Poultry can be housed under different systems based on following factors,
Firstly, Availability of land
Secondly, Cost of land
Thirdly, Type of farming activity
Fourthly, Climatic condition
Lastly, Labour availability
Broadly, poultry housing systems are classified into three systems:
- Free range or extensive system
- Semi-intensive system
- Intensive system
Firstly, Deep-litter system
Secondly, Slatted floor system
Thirdly, Slat cum litter system
Lastly, Cage system
1) Free range system
This system is adopted only when adequate land is available to ensure desired stocking density by avoiding overcrowding. We can rear about 250 adult birds per hectare. A range provides shelter, greens, feed, water and shade. Also, Foraging is the major source of feeding for birds. Shelter is usually provided by temporary roofing supported by ordinary poles. The fields are generally used on rotational basis after harvesting of crops by moving of birds from one field to another depending on cropping programme. Lastly, all categories of birds can be reared in this system. This system is most preferred for organic egg production.
- Less capital investment
- Cost of housing is least.
- Also, Feed requirements are less since birds can consume fairly good amount of feed from grass land.
- Fertility of soil can be maintained.
- The scientific management practices cannot be adopted.
- Also, Eggs are lost when laid inside the dense grasses unless special nests are provided.
- Losses due to predatory animals are more.
- lastly, Wild birds may bring diseases unless proper care is taken.
2) Semi-intensive system
As the name indicates birds are half-way reared in houses and half-way on ground or range, i.e. birds are confined to houses in night or as per need and they are also given access to runs. The houses are with solid floors while runs are fields only. Furthermore, the success of rearing depends on maintenance of condition of runs to reduce the contamination. Runs can also be used on turn basis. The stocking density rate on an average for adult birds is 750 per hectare. Also, this system is usually adopted for duck rearing. The feeding and watering facilities are provided in the pen.
- More economical use of land compared to free range system
- Also, Protection of birds from extreme climatic conditions
- Similarly, Control over scientific operation is some extent possible
- High cost for fencing.
- Need for routine cleaning and removal of litter material from the pen.
3) Intensive system
Birds are totally confined to houses either on ground / floor or on wire-netting floor in cages or on slats. It is the most efficient, convenient and economical system for modern poultry production with huge numbers.
- Firstly, Minimum land is required for farming.
- Farms can be located near market area.
- Also, Day-to-day management is easier.
- The production performance is higher as more energy is saved due to restricted movements.
- Scientific management practices like breeding, feeding, medication, culling etc. can be applied easily and accurately.
- Lastly, the sick birds can be detected, isolated and treated easily.
- Birds’ welfare is affected. They cannot perform the natural behaviour like roosting, spreading wings, scratching the floor with legs etc.
- Since they are not exposed to outside sunlight and feed sources, all the nutrients should be provided in balanced manner to avoid nutritionally deficient diseases.
- Lastly, chances for spreading of diseases are more.
Deep Litter System
In this system the birds are kept inside the house all the time. Arrangement for feed, water and nest are made inside the house. Also, the birds are kept on suitable litter material of about 3” to 5” depth. The word litter is used for fresh litter material spread on the floor. Usually paddy husk, saw dust, ground nut hulls, chopped paddy straw or wood shavings are used as litter materials. This arrangement saves labour involved in frequent cleaning of faecal matter (droppings), however it needs periodical stirring. Likewise, the litter is spread on the floor in layers of 2” height every fortnightly till the required is achieved.
- Vit B2 and Vit B12 are made available to birds from the litter material by the bacterial action.
- The welfare of birds is maintained to some extend
- Likewise, the deep litter manure is a useful fertilizer.
- Lesser nuisance from flies when compared to cage system.
- Because of the direct contact between bird and litter, bacterial and parasitic disease may be a problem.
- Also, Respiratory problems may emerge due to dust from the litter.
- The cost of litter is an additional expenditure on production cost.
- Lastly, Faults in ventilation can have more serious consequences than in the cage system
The built up litter
Similarly, Deep litter or built up litter is accumulation and decomposition of litter material and excreta until it reaches a depth of 8” to 12”, after an original start of 3” to 5” depth. Bacterial action decomposes litter and excreta into crumble form and heat is produced during decomposition which keeps litter dry and warm. If the amount of droppings exceeds the litter, fresh litter will be added to lower the amount of droppings. Periodical stirring of the litter should be carried out for an effective functioning of built-up litter. After one year, the litter is changed and the decomposed litter is used as good quality manure. The best built-up litter should be dry, friable and free from obnoxious odour.
Slatted (Slotted) Floor System
Furthermore, in a slatted floor, iron rods or wood reapers are used as floor, usually 2-3 feet above the ground level to facilitate fall of droppings through slats. Wooden reapers or iron rods of 2” diameter can be used on lengthwise of the house with interspaces of 1” between rods.
Firstly, Less floor space per bird is needed when compared to solid floor system.
Secondly, Bedding is eliminated
Thirdly, Manure handling is avoided
Fourthly, Increased sanitation
Also, Saving in labour
Finally, Soil borne infection is controlled
- Higher initial cost than conventional solid floors
- Less flexibility in the use of the building
- Any spilled feed is lost through the slots
- More fly problem.
Slat (Slot) Cum Litter System
This system is commonly practiced for rearing birds for hatching eggs production, particularly meat-type breeders. Here, a part of the floor area is covered with slats. Usually, 60% of the floor area is covered with slats and rest with litter. Feeders and waterers are arranged in both slat and litter area. In case of breeder flock, nest boxes are usually kept on litter area.
- More eggs can be produced per unit of floor space than all solid floors.
- Fertility is better with the slat cum litter house than with the all-slat house.
- Housing investment is higher with the slat cum litter house than with the all-litter house.
- The separation of birds from the manure beneath the slats commonly results in fly problems.
This system involves rearing of poultry on raised wire netting floor in smaller compartments, called cages, either fitted with stands on floor of house or hanged from the roof. It has been proved very efficient for laying operations, right from day-old to till disposal. At present, 75% of commercial layers in the world are kept in cages. Feeders and waterers are attached to cages from outside except nipple waterers, for which pipeline is installed through or above cages. Auto-operated feeding trolleys and egg collection belts can also be used in this rearing system. The droppings are either collected in trays underneath cages or on belts or on the floor or deep pit under cages, depending on type of cages.
- Firstly, Minimum floor space is needed
- Secondly, More number of eggs per hen can be received
- Less feed wastage
- Better feed efficiency
- Also, Protection from internal parasites and soil borne illnesses
- Sick and unproductive birds can be easily identified and eliminated.
- Clean eggs production
- Vices like egg eating, pecking is minimal.
- Broodiness is minimal
- No need of litter material
- Artificial Insemination (AI) can be adopted.
- High initial investment cost.
- Similarly, handling of manure may be problem. Generally, flies become a greater nuisance.
- Also, the incidence of blood spots in egg is more
- Problem of cage layer fatigue. (It is a condition, in which laying birds in cages develop lameness. It may be due to Ca and P deficiency but the exact reason is not known)
- In case of broilers, incidence of breast blisters is more, especially when the broilers weight is more than 1.5 kg.
Types of cages
Based on the number of birds in a cage, it is classified as;
- Single or individual bird cage (Only one bird in a cage)
- Multiple bird cage (From 2 to 10 birds, usually 3 or 4 birds per cage)
- Colony cages (Holding birds more than 11 per cage)
Based on the number of rows
Based on arrangement of cages
1) Stair-step cages
- a) M-type cages
- b) L-type cages
2) Battery cages (Vertical cages)
Based on the type of bird reared
Firstly, Brooder / chick cages
Secondly, Grower cages
Thirdly, Layer cages
Lastly, Breeder cages
