MANAGERIAL AND NUTRITIONAL STRATEGIES TO IMPROVE PRODUCTION EFFICIENCY OF HEAVY BROILER CHICKENS
2010 Annual Report
1a.Objectives (from AD-416)
The objectives of this research are to evaluate energy usage patterns in modern broiler housing throughout the production cycle and to determine the effects of energy saving measures on thermal conditions and production efficiency in broiler chickens during the brooding phase.
1b.Approach (from AD-416)
Effects of reduced energy usage regimens and measures to improve energy efficiency in modern broiler housing on the thermal environment and subsequent production efficiency will be evaluated.
A mobile broiler house simulator was designed and constructed to quantify the ranges of evaporative cooling system cooling efficiency in typical Mississippi weather conditions. Multiple fan stages allow for testing the effects of different air velocities and the effect on water removal from the pad material. Preliminary results show that new evaporative pads with the suggested 350-400 ft/min air velocity through the pad typically achieves 70% cooling efficiency, which is less than the 75% cooling efficiency used in design calculations. This project is monitored via phone calls, emails and direct visits.
