I would suggest you use the male broiler breeders from another brand/line. Using male broilers ( hybrid cross between a female dual purpose synthetic female type and a meat type male) will produce a chicks with a scattered range of uniformity and an…
Sajid,
In order to obtain the accurate calculations for your ventilation requirements you would need to calculate the cross section of the house and this includes calculating the space below the roof ridge to the eaves as well. I would suggest you g…
Dr Anju,
I have seen the same situation in one of the breeding farms I visited. The birds were 31 weeks old and on postmortem I saw the same "regressed ovaries." Actually the ovaries have not regressed, they were still in the process of development…
In dealing with Marek's one should start after depopulating the house. All debris and feathers from the previous occupants should have to be removed from within and around the house and the house cleaned thoroughly before disinfection. I am more con…
Just read your message since I,m still new in this group. Have you had any success in your hiring? if not, I could probably help you. My email is sansigar@yahoo.com
Thanks Dr. Babatunde. Yes I guess my query wasn't well phrased. The question was in reference to the Industry preference for the use of White egg layers for the production of what is commonly termed as "Clean Eggs" but which I prefer to call Vaccine…
Hello Nina , Another way to sex Day old Chicks is through color sexing. This is the common way to sex brown egg hybrids. The commercial pullets come out brown and the cockerels are white. Color patterns on the head of barred feather birds are also u…
Hello Everybody! I just joined your group. I wonder if anybody can explain why the preference for "Clean Egg" production in on White Egg Layers? In a country where the common Layer types are all Brown Eggers couldn't Brown egg Layers also fulfill th…
Ok rekesh,
What type of housing system (dimensions and facilities) are you referring to and what poultry are housed therein. I think these are relevant questions you would have to provide in order to compute for the minimum ventilation you require. In general you should keep in mind the basic functions of the ventilation system as outlined by Mr. Robert Barnwell of Cobb-Vantres as follows:
1. Create an air exchange in the house.
2. Provide Oxygen (air volume) demand for the birds.
3. Allow control of relative humidity.
4. Insure good air quality at all times.
5. Remove negative gasses from the environment.
6. Obtain necessary pressure drop inside the house.
7. Accomplish an acceptable effective temperature.
8. Manage the environment for best results.
9. Improve overall production efficiencies.
I have never experienced winter here so I cannot answer your question, but I can refer you the expert in ventilation, Mr. Robert Barnwell, from Cobb_Vantress. You can get in touch with him via the Cobb-Vantress websiteor through his email - Rbarnwell-ESI@worldnet.att.net or barnwellr@cobb-vantress.com. What would be most important in a winter situation is that you would need to maintain the house temperature within the zone of comfort while at the same time keeping the air exchange sufficient enough to have good air quality defined as follows:
Oxygen > 19%
CO2 < 0.3%
Carbon Monoxide < 10ppm
Ammonia < 10 ppm
also as outlined by Mr. Barnwell.
