1 Must not only meet the basic needs of the birds but must also be finely tuned to fully optimize the breed s potential. Some of the guidelines may need to be adapted according to your local conditions with assistance from our technical Cobb Broiler Management Guide is part of our technical information library, which includes Hatchery, Grand Parent, Breeder, Vaccination & Nutrition Guides, Technical Bulletins and a full range of performance charts. Our recommendations are based on current scientific knowledge and practical experience from around the world. You should always be aware of local legislation, which may influence the management practices that you choose to Cobb Broiler Management Guide is intended as a reference source and supplement to your own flock management skills so that you can obtain consistent good results from the Cobb family of Cobb commitment to genetic improvement continues to increase the performance potential in all areas of broiler and broiler breeder production.

2 However, to attain both genetic potential and consistent flock production, it is important that the flock manager has a good management program in place. The worldwide success of Cobb has provided knowledge and experience over a wide range of climatic conditions, controlled environment and open housing. The Cobb Broiler Management Guide is designed to assist you in developing your management program no matter your housing or environmental pointsLook for this symbol throughout the guide that highlights Key Points that emphasize important aspects of husbandry and critical Welfare TipsLook for this CobbCares symbol throughout the guide that highlights Animal Welfare Tips and important aspects for management to improve welfare outcomes of the broiler.

4 A roof that is well Heating system with sufficient capacity in accordance with the Ventilation system designed to provide sufficient oxygen, maintain litter moisture conditions, and provide optimal cooling capability for the A lighting system that provides even distribution of light at bird Energy efficient choice of the above components: insulation, fans, heating and Energy Efficient House Design RequirementsWhen planning the construction of a broiler house, one should first select a well-drained site that has plenty of natural air movement. The house should be oriented on an east-west axis to reduce the effect of direct sunlight on the sidewalls during the hottest part of the day.

5 The main objective of this orientation of the broiler house is to reduce the temperature fluctuation during any 24-hour period. Good temperature control always enhances feed conversion, bird comfort, and efficient growth are many things to consider when selecting the most suitable type of broiler housing and related equipment. Though economic constraints are generally foremost, factors such as equipment availability, post-installation service and expected useful life of the equipment are also critical. Housing should be cost and energy efficient, durable and provide a controllable Design and InsulationThe most important insulation requirements are in the roof.

6 A well-insulated roof will reduce solar heat penetrating the house on warm days, thus decreasing the heat load on the birds. In cold weather, a well-insulated roof will reduce heat loss and energy consumption needed to maintain the correct environment for the chick during the brooding phase, the most important time in the development of the broilers. The insulating ability of materials is measured in R or U-values. The higher the R-value the greater the insulating properties of the material. When selecting any insulation material, cost per R-value rather than cost per thickness of material is the most important roof should be insulated to a minimum R-value of 20-25 (climate dependant).

7 U value - coefficient of heat transmission, is a measure of the rate of non-solar heat loss or gain through a material. U-values gauge how well a material allows heat to pass through. The lower the U-value, the greater a product s resistance to heat flow and the better its insulating value. The inverse of the U-value is the required roof U-value - (climate dependent).Following are some insulating materials and their respective to maximizing bird performance is the provision of a consistent house environment. Roof design and insulation will not only assist with a consistent environment for the flock, but will also help conserve heating costs, reduce solar energy penetration, and prevent condensation inside the chicken house.

8 Large fluctuations in house temperature will cause stress on the birds and affect feed consumption. Furthermore, these fluctuations will result in additional energy expenditure to maintain body roof overhang should be m (4 ft).

9 A 25 cm (10 ) mini curtain installed on the outside of the curtain will further prevent air leaks over the top of the curtain height. The curtains should fit into an envelope which is a 25 cm (10 ) mini curtain that seals the curtain vertically on both ends. Curtains need to be sealed at the base to prevent air leaks at floor level. All holes and tears in sidewall and/or inlet curtains must be repaired. Curtains work most efficiently if operating automatically using both temperature and wind speed as criteria for opening and closing. The optimum stem wall height is m ( ft). cm (10 ) mini curtain25 cm (10 ) curtain Installation Inlets in tunnel housing should be installed as close to the ceiling as possible about 30 cm (12 ) below the sidewall eaves.

10 If the ceiling has structural obstructions such as beams, a directional flap can be used on the top of the inlet and a solid air ramp should be installed to aid the air in passing the obstruction see image above. All inlets require wind proofing covers on the outside of the house to help prevent outside wind from opening the inlets. The inlet cover should be at least 30% more than the cross sectional area of the inlet to minimize air ramp over the top of the obstructions to aid the incoming air to the top center of the air jetsThe result is cold air at bird levelAdjust height/opening of inletAnimal Welfare TipAdd a solid air ramp to avoid obstructions that will result in cold air dropping to the floor.
