Arkansas Turkey Growers Face Variety of Challenges - By G.T. Tabler, Poultry Science Department at the University of Arkansas's Avian Advice - The increasing urban expansion into rural areas creates numerous challenges for livestock producers to various types of farming operations. A strong livestock industry is essential to the nation’s economic stability, the viability of many small rural communities, and the sustainability of a healthful, plentiful and high quality food supply for the American public.


Arkansas turkey growers produced 29.5 million turkeys in 2002 ( USDA, 2003), making the state third in turkey production behind North Carolina and Minnesota. As any grower can verify, raising commercial turkeys is no easy task. In comparison to broiler chickens, turkeys are extremely difficult to start, the brooding period is a much more stressful time for both poult and grower, and turkeys remain on the farm for a much longer period increasing the likelihood that something may go wrong before the flock sells. Let’s look at some of the challenges faced by Arkansas turkey growers and how to meet these challenges.

Summertime Temperatures

Turkeys are generally most comfortable when temperatures range from 70-79° F (Anonymous, 2003). Feed intake and growth may be affected as temperatures rise above 80° F and temperatures exceeding 90° F, can result in heat exhaustion or heat prostration. High temperatures are particularly stressful when coupled with high humidity levels.

Heat stress is always a concern of Arkansas turkey producers during summer months and can produce significant losses if growers are not properly prepared. Several factors affect heat production and the turkey’s ability to deal with heat. The digestion of food, the growth process and bird activity all create heat, which the turkey must dissipate (Nixey, ND). As the temperature increases, feed consumption decreases and turkeys begin to pant which negatively affects the performance and profitability of the flock.

A turkey’s first objective is simply to stay alive. Turkeys are warm-blooded and must maintain a relatively uniform body temperature of 105-107°F over a wide range of environmental conditions. If heat produced by the bird is greater than heat that is lost, the bird’s body temperature rises; if it rises 9-11°F and reaches 116° F the turkey dies from heat prostration. Several methods exist for the turkey to lose heat (Cereno, 1998):

  1. Radiation - body surface temperature is cooler than air surrounding it
  2. Conduction - bird comes in contact with and loses heat to a cooler surface (litter)
  3. Convection - cool air contacting body surface is warmed and rises, carrying away heat
  4. Water vaporization - a bird’s nasal cavity is a heat exchanger and helps rid the body of excess heat through evaporative cooling
  5. Fecal excretion
  6. Egg production

How efficiently turkeys can lose heat will depend on air temperature, humidity, air movement over the bird, and stocking density. Turkeys pant to increase the rate of heat loss by evaporative cooling. However, older, heavier birds produce more internal heat and are less able to cool themselves through convection and evaporation. The extra weight might be why higher temperatures are more stressful on toms than hens (Anonymous, 2003). Also, be aware that birds suffering respiratory problems will have a reduced ability to cool themselves through panting. In addition, the more birds in the house, the more heat they generate and they will tend to absorb each other’s radiant heat load.

Air movement (ventilation) is critical if turkeys are to survive summer conditions. Maximize natural ventilation by keeping grass and weeds cut around buildings. Do not park tractors or equipment alongside houses as this restricts air movement through the buildings. You are better off with grass around your houses to absorb heat (if you keep it cut) instead of bare ground because bare ground will reflect heat back into the houses. Make sure your fans are properly maintained.

Keep blades, shutters and safety grills free of dirt and debris. Change fan belts at least once per year. Worn or loose belts can reduce fan efficiency by 20-30 %. Turn fan thermostats down low enough that the fans will run late enough after sundown to give the birds a chance to cool off. Flush water lines regularly to provide cool water to the turkeys; cool water allows the turkey to transfer body heat to the water they drink.

If you have a generator, make sure it is maintained and ready in event of a power failure. If you don’t have a generator, seriously consider purchasing one. They are a somewhat expensive investment if the power stays on, but a generator can pay for itself in one afternoon if the power goes off for an extended period.

Some growers supplement the drinking water with vitamins and electrolytes to reduce heat stress. Vitamins in the water are a good way to insure turkeys are getting what they need during hot weather when feed intake may be reduced. Electrolytes help maintain adequate blood pH which becomes elevated when turkeys pant for extended periods. Always talk to your service technician before starting any supplementation program since they know what works and what doesn’t.

Turkeys normally decrease their activity level and stay away from feeder pans to avoid creating additional internal body heat when the weather is hot. Thus, keeping birds as quiet as possible during the heat of the day and considering an intermittent lighting program to encourage nighttime feeding may help. However, turkeys must be offered a period of complete darkness because it is during this time that the tibia (leg bone) grows at its optimal rate (Monk, 1998). Sprinkling turkeys with water can help fight heat stress when temperatures exceed 80-85°F. However, the amount of water used will vary greatly with condition of the house and the birds and producers should avoid using too much water since it can increase humidity to dangerous levels. Again, consult your service technician before changing your lighting program or starting a sprinkling program.

Pathogen Load

Management programs that will allow turkeys to perform to their genetic potential should be the goal of all producers. Obviously, pathogens can reduce turkey performance and should be controlled. Unfortunately, with the technologies currently available to the industry, complete eradication of the pathogen load in live production is not possible. We can, however, make every attempt to reduce the microbial population through Best Management Practices that include a strict biosecurity program.

Be aware of comings and goings on your farm and make it a rule that no one gets on your farm who doesn’t belong. Feed truck drivers and technical service personnel must have access, but after these folks are accounted for, the list becomes extremely short. Friends, neighbors or other visitors have no vital purpose around your operation and should be excluded. It is up to you to enforce this. You may politely make visitors aware that it is not that you are antisocial, but you have thousand dollars and many hours of “sweat equity” invested in your operation and you cannot afford to have a disease challenge on your farm. Each farm has its own unique microbial population that the turkeys “become accustomed to,” but visitors tend to introduce organisms that are not common to your operation and lead to production or disease troubles. You must minimize traffic flow on your farm, the risk is simply too great to do otherwise. Therefore, take necessary steps to ensure that the only visitors to your farm have a good reason to be there.

The live production process in the turkey industry is a combination of management practices, bird health, the nutrition program and the unique farm environment (Figure 1). Nutrition, like management, must be focused on insuring that the turkey can perform to its genetic potential. Proper bone development is vital in insuring that turkeys achieve their full genetic potential. Any factor that negatively influences bone development will result in stress when the turkey attempts to walk, leading to decreased activity, reduced feed intake, and diminished growth rates (Monk, 1998).

The farm environment directly impacts bird performance. A favorable environment optimizes growth and strengthens the bird’s ability to resist disease. The environment also influences the microbial population unique to each farm. Published research has demonstrated that birds in “clean” environments grew 15% better than those in dirty environments (Fernandez, 1998a). If bird health is compromised, the turkey will likely never reach its genetic potential regardless of your management program. Fernandez (1998b) indicated a vector control program and a clean water supply are also critical to reducing pathogen loads.

Effective rodent control programs involve a rational, systematic baiting procedure, preventive facilities management and constant monitoring. Rodents are often vectors that transmit disease organisms from one flock to the next. Even if facilities are cleaned and disinfected, the presence of rodents can jeopardize sanitation efforts. Darkling beetles are another vector which has been implicated in many poultry diseases.

Beetles have been found to be a source of transmission for Salmonella, Marek’s Disease, E. coli, Infectious Bursal Disease, Newcastle Disease, Clostridium and numerous other diseases (Watkins, 2001). Approved insecticides are available for use after house cleanout for beetle control.

The role of water is certainly underestimated in both turkey and broiler production. High quality drinking water is critical for a healthy environment in both turkey and broiler facilities. Fernandez (1998b) indicated that 45 of 95 (47%) of untreated water samples from various turkey farms were contaminated with bacteria. The most common bacteria found were Pseudomonas, followed by E. coli. Bordetella (which causes turkey coryza). Bordetella has also been isolated from the inside of nipple drinkers and from the rubber seal in the water line regulator in houses with Bordetella-positive turkey flocks (Watkins, 2002). Thus, it is important to reduce the microbial load in the water system by treat water lines during house cleanout, and sanitizing watering equipment during house preparation (Fernandez, 1998b).

Other Challenges

Pathogen load and heat stress are only two of numerous challenges faced by Arkansas turkey growers. Producers must also be alert for coccidiosis which causes economic loss through poor performance and secondary infections. Coccidiosis in turkeys is difficult to diagnose compared to chickens since , in turkeys, visible lesions are rarely seen and an accurate diagnosis requires the use of a microscope. Clinical signs include, weight loss, decreased rate of gain, listlessness, and loose droppings (possibly with blood or mucus), but these are the same symptoms that a variety of other diseases or ailments may exhibit.

The proper house environment during winter is also a major challenge. Houses are usually closed tightly and ventilation is at a minimum during cold weather to conserve fuel. Be aware, however, that adequate ventilation is necessary to guarantee sufficient air exchange, provide needed oxygen, and prevent carbon dioxide (CO2) buildup in the house. Carbon dioxide levels are always a concern in turkey production facilities. In research trials, seven times the normal level of CO2 did not significantly affect livability at 14 days, but average body weights were up to 15% poorer in non-ventilated houses (Fernandez, 1998b). Equally important was the deterioration of bird uniformity that accompanied the depression in weight. Proper winter ventilation is critical if the flock is to perform up to its genetic potential.


Turkey growers must be constantly vigilant of conditions within the turkey house. High summertime temperatures are always a threat, especially when accompanied with dangerous humidity levels.

Significant costs in lost performance and/or mortality can be expected if measures are not taken to reduce heat stress. Proper winter ventilation is also important to provide an environment that will allow the turkey to perform at its best. Steps must also be taken to control the pathogen load in turkey production facilities. Practice stringent biosecurity and do not allow anyone on your farm unless they have a reason to be there. Monitor bird health and contact your service technician at the first sign of a possible disease outbreak. Turkey production requires that numerous challenges be met along the way to producing a healthy, profitable flock. To be successful, Arkansas turkey producers must meet and overcome these challenges on a daily basis.
