Having unexpected mortality in poultry is never a good thing. Valuable resources for producers are the four Alabama State Veterinary Diagnostic Laboratories. All poultry from Alabama submitted to one of these labs are examined free of charge. Lab services include diagnosis of diseases or other problems using the lab techniques of microscopy, culturing, serology, or molecular techniques.
After a diagnosis has been made, recommendations to prevent the problem may be provided. With this information, an effective plan can be devised to prevent or eliminate further losses.
Before submitting a sample, call the closest diagnostic lab to clarify what type of specimen is needed. If the lab is too far, overnight ship fresh dead birds that are properly chilled and packaged. Notify the lab in advance that the box is coming.
Basic procedures for submitting poultry samples to a diagnostic lab are as follows:
- For birds less than one week old, recent mortality (less than 24 hours) is preferred.
- For birds more than one week old, the best sample usually includes several very sick birds as well as recent mortality. Call the lab for recommendations
on the proper sample size.
- If there is a production problem, such as poor growth rate or egg laying, collect for submission a random sample of live birds and daily mortality.
- An accession number will be assigned when the sample has been received at the diagnostic lab. Test results will be mailed to the mailing address
provided on the submission. Not all submitted animals will be returned.
Samples to be submitted can be dropped off at one of the four labs. All birds should be placed in coops or cardboard boxes. Be sure that the bottom of the box is taped. If the box isn’t big enough, get another one. For live birds, it is better to have too much room than too little room.
Submission forms are available at each of the diagnostic labs or on the website at http://www.labs.alabama.gov/home/submission-forms. Fill out the form
completely including the flock history, sample size, symptoms, suspected diseases, size of flock, age, and county where the birds are located. Then take samples to one of the four diagnostic labs:
- Thompson-Bishop-Sparks State Veterinary
890 Simms Road
Auburn, AL 36831-2209
- Michem-Sparks State Diagnostic Laboratory
1833 Industrial Boulevard
Boaz, AL 35957
- J. B. Taylor State Veterinary Diagnostic Laboratory
495 State Road 203
Elba, AL 36323
- Hinton Michem Poultry Diagnostic Laboratory
1001 College Road
Hanceville, AL 35077-0409
Reminder: If mailing the samples, make sure that the lab is notified before shipping.
- Frozen poultry. DO NOT FREEZE dead poultry. Recent mortalities should be kept refrigerated or in a cooler with ice.
- Number of birds submitted. Call the lab first to discuss your problem and request a recommendation on the number and type of birds to submit.
- Flock history. It is important to maintain good record keeping with your flock. This includes the age of the birds, any new additions or subtractions to the flock, a change in egg laying, and the number of birds that have died each day.
- Sick birds. Select only birds that have symptoms typical of the primary problem. Birds that were easy to catch or have unusual lesions inconsistent with the typical mortality are not good choices to submit. Submitting all live or all dead birds can make determining a diagnosis more difficult. With all live birds, the submitted birds may not have been infected with the disease-causing agent. With all dead birds, the disease-causing organism may be difficult to isolate and identify.
