The growing importance of nighttime air quality

1.ventilation.2.population density .3.to avoid water spillage use nipples n remove any wet litter replace with dry one.4.use of soya full fat with maize germ causes wet droppings.so avoid and your problem will be solved.i used to have problem with my broilers but now its no more.

Use nipples.avoid soya full fat and maize germ together in the feeds.

En resumen a la lectura de este informativo totalmente de acuerdo y muy provechoso, por la real importancia durante toda la vida de un ave, la buena cantidad y calidad del aire.

All the comments above are valuable. Ammonia is one of the problem . By doing a good management, it is possible to control the problem. One of the major criteria in poultry production is to provide a quality OXYGEN to the birds. We must get rid of excess carbon d'íoxide; carbon monoxide etc. Nowadays, we are talking a lot about air pollution. What about our birds? We are increasing the air speed for a better ventilation. But in industrial broiler farms, we still find birds gasping despite improved ventilation. It is a complex situation and the farmer needs to be very close to his flocks. Welfare is important but we should have a balance to keep our birds healthy and to give the customers a quality product.

Air exchange have a formula like everything we do. You must have 0.7 cubic metters /kg lw, optimum inlet opening and proper underpressure.Actualy we do not need speed of air ( except cooling situation). We need air, proper volume of air and underpressure.

Ing. Dragan Ionut: Why should a ventilation rate be based on bird weight? Mike Czarick

Dear Dr Mike In order to have a proper ventilation you must know at least a minimum ventilation . Usualy , for broiler we use 0.7 cubic meter per kg live weight. I do not know how is the weather in Georgia but in Romania in winter we have usualy -20 degree celsius . We must know how much is the minimum ventilation for a minimum gas consumption. And we have a formula.... And - a response for your question , because the diferent volume of co2 produce by the bird on different ages and the different need of O2 for different weights

Dear Dr Mike. This answer is a generally answer . Because you already study this situation ( I mean minimum ventilation and ammonia concentration in poultry houses- I read some of your articles on internet ) I am glad if you want to share your experiences with us . What is your opinion about minimum ventilation ( if we will exclude the humidity correction ) . I want to know your opinion about minimum ventilation at 55-60 % RH and without co2 and nh3 sensors Thank you

Mortality Effected due to low temperature at night time. Hi there, I have poultry of 7000 chick but the rapid death(30-40 per day) rate is make a big issue for me. i have a farm of 300 m but temperature is not maintain.I do lot for this but not able to got my target (Eg : 35'C). please suggest me particular method to maintain temperature at winter night eg:2 - 3'C out side temperature. If any suggestion pls mail me ( vineet4458@gmail.com ) Please Help its matter for me a lot.
