Important information for poultry exhibitors at 2019 fairs & exhibitions

There is a shortage of the pullorum antigen used to test all poultry (except turkeys) for Pullorum-Typhoid disease. If the birds you exhibit at the county Fair or Minnesota State Fair originated directly from an National Poultry Improvement Program (NPIP) classified Pullorum-Typhoid Free hatchery or flock, this issue will not affect you. 
If not, the Minnesota Board of Animal Health (MN BAH) exhibition rules require a test within 90 days of the exhibition. Because MN BAH does not plan to waive the testing requirements at this time, we are trying to preserve what antigen we do have and are encouraging the use of this Poultry Exhibition Statement of Origin form instead of pullorum testing birds if they originated from an NPIP flock or hatchery. 
Additional information on the poultry exhibition requirements can also be found on the Boards website using the links provided below.

Bedding source and stocking density affect turkey hen performance and footpad health

By: Gabriella Furo, Ph.D. student
Department of Animal Science, University of Minnesota

What is footpad dermatitis (FPD) and why should I care? Footpad dermatitis is a skin inflammation, and a frequently occurring problem in turkey production worldwide, which can affect the turkey performance, including body weight and feed intake. The signs of FPD include thickened scales (hyperkeratosis), discoloration, dark brown and black lesions, ulcers which develop on the footpads and toes of poultry. Footpad dermatitis is associated with potential pain, therefore it is an animal welfare issue, and FPD can affect turkeys at any age.

There are many contributing factors in the development of FPD, such as nutrition, past and existing diseases, but the most important factor is litter moisture. Research studies recommend to keep litter moisture under 30% in order to minimize the incidence of FPD. The lesion develops quickly with early signs seen 24-48 hr after exposing the birds to high litter moi…

Turkey Reoviral Arthritis/Tenosynovitis - Part 4

This is 4th article in a series of 4 By: Rob Porter DVM, PhD, Sunil Mor, DVM, PhD, and Sagar Goyal, DVM, PhD

Although many questions about turkey reoviral arthritis have been addressed in this four-part series, it is clear that despite several years of research and investigation there are many questions remaining to be answered. We are participating in a national effort to address industry concerns about reoviral arthritis.

Turkey reovirus subcommittee - A Reovirus Subcommittee of the National Turkey Federation has met during the last two years and seeks to organize both industry personnel and university researchers to address the TARV issue. The mission is to ensure transparency and collaboration to develop turkey-specific solutions to assist the industry in controlling turkey reoviral arthritis. This subcommittee met at the Minnesota Poultry Federation Convention meeting on March 13, 2019 to identify four focus area…

Turkey Reoviral Arthritis/Tenosynovitis -Part 3

Is TARV a seasonal problem?  The 719 submissions from March 2010 to May 2018 consisted of a total of 926 samples of tendon. There was no statistical evidence that TARV diagnostic submissions were seasonal, although positive submissions were higher in January, April, July, and December.
How is TARV transmitted?  Our studies have demonstrated that inoculated poults can transmit the infection laterally to pen mates, likely through manure. It is generally believed that TARV can be egg transmitted from breeders to offspring although no study is available that has tackled this issue. However, egg transmission of chicken arthritis reovirus (CARV) has been well documented and has been effectively controlled by vaccination of broiler breeder flocks. Our industry partners have shown that, in some instances, intramuscular vaccination with autogenous, killed TARV can reduce onset of lameness in offspring,…

2019 Winter Workshops for Backyard & Small Flock Poultry Production

UPDATED 3/4/19 University of Minnesota is holding a series of workshops around the state on Backyard & Small Flock Poultry Production. The audience is mainly for those who are new to poultry, but there is something in the workshop for experienced bird keepers as well.

Turkey Reoviral Arthritis/Tenosynovitis - Part 2

This is the 2nd of a 4 part series.

Has the presentation of TARV remained the same? Grossly, most legs have periarticular fibrosis and edema without gastrocnemius tendon rupture; however, there is also edema of the shank accompanied by rupture or laxity of one or more of the digital flexor tendons (Figure 1). In the last two years a greater percentage of the TARV cases are complicated by bacterial infections e.g., Escherichia coli, Ornithobacterium rhinotracheale, Pasteurella multocida and Staphylococcus aureus. In some of the hock joints, one might also observe marked erosion of the articular cartilage of the tibiotarsus (drumstick).

Turkey Reoviral Arthritis/Tenosynovitis

This is the 1st article in a series of 4.
What is turkey arthritis reovirus and where did it come from? Avian reoviruses (ARVs) are RNA viruses that are ubiquitous in domestic poultry with 80% of them being non-pathogenic. However, ARVs have also been associated with enteritis, hepatitis, neurological disease, myocarditis, respiratory distress and viral arthritis/tenosynovitis in chickens and turkeys. Clinical disease associated with ARV is mostly dependent on age, and immune status of the bird, virus pathotype, and route of exposure (oral, intratracheal, footpad, or subcutaneous). Reovirus was isolated from joints and ruptured tendons of turkeys with tenosynovitis/arthritis as early as 1980; however, experimental infection of turkey reoviruses failed to reproduce the disease. After, a hiatus of >20 years, the problem of reovirus-associated lameness in turkeys re-emerged in the Midwestern …
