Reduction of bird heat stress. M. Czarick (University of Georgia)

I totally agree, Mike! Sometimes I see people treating the water with no water analysis.

Dear Dr. Czarick

So many thanks for your presentation. I have a question for you relating to Grandparents:
Referring to a Broiler Breeders Grandparents male house, some growers argue that this type of heavy-weight birds are sensitive to increased air speed mainly for fear of early molting “considering the genetics issue” (the air speed does not exceed 1.7 m / s during production)!

We found panting birds, especially in the second half of the house out of the cooling area (closed system) when outside temperature rises to above 35 ° C. Is their argument considered a reasonable justification not to increase the speed of air above 1.7 m/s in houses of 14 meters wide with a length of 130 meters?

This house is newly constructed and well equipped in terms of cooling area, insulation and number of fans where the air speed reaches more than 2.5 m/s when all tunnel fans are running.

I agree with Dr. Czarick, producers add too many additives into the drinking water that may not be necessary and only increase production cost. I started with healthy hicks, gave vitamins in the water for the first week and just before and after vaccination to help them get over vaccine stress, made sure that the birds were comfortable, good ventilation, dry litter and other management steps that did not add unnecessary cost during the growing cycle.

Dear Dr. Czarick

Thank you very much for your presentation. I have 2 questions for you.
1- In a region with hot summer and cold winter, which methods of ventilation will be correct. As we need minimum ventilation in cold weather and tunnel ventilation in summer.
2- In a region with hot and humid summer, what kind of ventilation could help us?

Best Regards

We want to construct broiler tunnel houses 60 feet x 600 feet x 10 feet high at altitude 940m.
How much cooling pads and ventilation fan (54" 53000 m3/hr) should I use to obtain 2m/min air flow as mentioned in your video?

I cannot answer this but it could be helpful for whoever attempts to for a temperature profile throughout the year at the location planned to be supplied.

Also whether you plan to use electricity from the grid or solar electricity production.

1- What is the best dimensions for poultry house to get Homogeneity of temp. Inside the house?

2- Are there differences in dimensions between broiler, breeder, grandparent?
