Dr. Michael Hulet Associate Professor Poultry Science With the onset of summer, poul try producers should be keenly aware of the environment in which they grow poultry. Poultry can tolerate a wide range of environmental condi tions, but most of these conditions are not conducive to optimum growth or efficiency. Poultry perform best when the environment around them minim izes stress and allows all nutrients to be used for growth and repro duction. If we evaluate summer time production and the natural stressors that inhibit optimum growth, we must be aware of cer tain management factors that will Get The THE ONLY * OUT front ZERO P TURNING RADIUS MOWER MADE IN 30” /J I TO 50” CUTTING WIDTH U AT AFFORDABLE PRICES Increase production with a new Spirit.

Among these factors are temperature (ventilation) and water quality. Ventilation Young poultry will seek an environment where they feel com fortable. Early in their life, chicks and poults are susceptible to drafts and changes in temperature of one or two degrees Fahrenheit There fore, in the brooding stage, grow ers must be careful to observe the birds’ behavior and keep the temp erature constant If the chicks are huddled together, determine whether the behavior is caused by a low ambient temperature or if a drafty condition exists. Air direction is important for young birds the inlet air should be directed toward the ceiling to temper and mix the air coming into die house. Con versely, air for older birds (greater than 4 weeks) is a means of cooling the birds during the summer. LANCASTER CO.

Peachy And Sons Rt 1 Box 172 Route 304 Winfield, PA 17889 717-968-0465 Air rushing over the heads of the birds by directed vents or circulat ing fans within the house helps to moderate the environment at the level of the bird. Turkeys which have more featherless area on the head and neck and naked neck chickens are better able to utilize this method of heat dissipation in hot weather than are commercial broilers. At very high temperatures, or if a hot spell starts quickly and doesn’t allow a time for acclima tion, mortality as well as tremend ous decreases in growth can occur in poultry flocks. Under such situ ations, circulation of air within the house as well as the addition of moisture by fogging can help “cool” the birds and prevent losses and poor performance. Ventilation equipment should also be checked and cleaned to allow for maximum air flow. Dur ing the winter, the combination of condensation and poultry dust coats belts, motors, wire mesh around fans and air vents, fan blades, fan levers, etc. and restricts air flow to the birds. “Spring clean ing” or “preventive maintenance” is, therefore, needed and shouldn’t be delayed until the hot weather occurs. Alarm systems should also be routinely checked to prevent a dis aster that can occur when power outages eliminate mechanical ven tilation, which can suffocate a flock. Other ventilation systems (automatic vents, thermostats, etc.) should also be maintained.

Water Quality Fresh, clean, and cool water is the desire of most poultry produc ers. Between flocks of birds, water systems should be cleaned with a line cleaner and drained. Prior to placement of birds, the line should be flushed so that fresh, cool water is available for young chicks or poults. Frequently, chlorine treatments are used to help decrease contami nation of waterers. Routine clean ing and disinfection is also very important The waterers arc ideal places for the replication of bacteria. Dr. Eric Gonder, a poultry veterinarian from Goldsboro Milling, Inc., has reported that water in a trough with nutrients from feed residue held at 68-70 degrees Fahrenheit is an ide al incubator for bacteria. He prop- osed that if two bacteria were added to a feed-contaminated watej trough environment, after 10 hours you would have the bacterial equivalent of raw sewage. There fore, consistent cleaning of water troughs followed by the use of an effective disinfectant can help decrease the amount of coliform bacteria consumed by the flock. This fact also helps explain the Dryer Line Includes 63 Models ASSUMPTION, 111. Air stream Dryer division of Grain Systems, Inc. (GSI) has introduc ed an innovative, more efficient line of dryers.

Nipple waterers have no common water bath for growth and accumulation of bacteria, not to mention the decrease in water spil lage and drier litter that occurs as a result of using these drinkers. Unfortunately, no nipple watereis have yet been developed to adequ ately supply the water demands of finishing turkeys. Water level (trough, bell) or water pressure (nipple) need to be adjusted during high ambient temperatures to allow for. increased water consumption by the flock. When adequate water volume is not supplied, feed con sumption is decreased and growth is lowered. Your management is the envir onmental protection agency (EPA) for your flocks. By protecting against unhealthy environments, you will produce healthier and more productive birds. Fresh air and water are basic to good production practices.
