Tour Japan some facilities of Mitsui and Co., Ltd. Recent earthquake damage will curtail visits to some of the agricultural businesses and his torical landmarks in Kyoto and Hiroshima. While in Tokyo, they will visit the corporate headquar ters of Toyota. The officers will meet with their Japanese counterparts members of the Future Farmers of Japan (FFJ) to further extend contacts between the next genera tion of agricultural leaders for both countries. Despite the disas ter in their country, FFJ has man aged to reassign each officer with a Japanese host family for one weekend to learn more about the culture and traditions of one of the United States’ most important trading partners. The international program is sponsored by Mitsui & Co. (USA).

Many different variations of vaccination progrtfhs are in use. Proper scheduling of vaccination requires knowledge of the specific type of disease to be protected against, age of the birds, concurrent management procedures, disease status of the flock, and the duration of immunity that can be expected from the vaccine. Poultry veterinarians and other poultry health specialists can recommend sound vaccination prog rams tailored to specific situations. Most commercial vaccines have been stringently tested and quality controlled for purity and efficacy. Vaccine com panies make very specific recommendations on how their products should be handled and applied. These instructions should be followed closely in order to ensure that the flock will be properly protected. Improvements and innovations in poultry vaccines are occurring constantly in response to industry need. Responsible use of quality vaccines is an extremely valu able tool in controlling disease. However, it will not make up for the gross deficiencies in management of some of the other control methods. Sound biosecurity and stress reduction measures are important adjuncts in making vaccination work for your flock. 111 • All-new 16-speed Power Shift, transmission: Minimal gear meshes ensure maximum power flow.

Although medication is the strategy most often thought of as traditional disease control, it is arguably the least important to total flock health. Medication, when instituted in response to a disease problem is considered “damage control” rather than disease control. The disease is often out of control by that point. Medication certainly can help reduce sickness and mortality significandy, especially if instituted early in the disease course. It can, however, be a waste of time, effort and money if not done properly. Antibacterial and anticoccidial drugs can be used at both treatment and preventive levels. Anticoccidials are invaluable in preventing losses due to coccidiosis. Their use is considered a necessity of modem poultry production. Antibacterial drugs (antibiotics) are not effective against viral diseases. However, they are used in some situations in which a viral problem has been implicated in order to prevent or reduce secondary bacterial infections that inevitably follow. Proper use of chemotherapeutic agents should be based on a correct diagnosis of the disease at hand, and specific target ing of a drug to the disease agent. If a bacterial disease has been diagnosed by culture, a laboratory test to determine the best drug to use against the bacteria found in the birds is in order. In the meantime, a “best guess” may be employed to start the birds on a treatment that is likely to help. For exam ple, Staphylococcal infections are likely to be helped by peni cillin, especially if the drug had not been extensively used on that farm previously. Poultry drug lists and guides are available from many sour ces. Advice from poultry health specialists can be useful in guiding drug use in specific situations. Poultry drags are usually mass applied by inclusion in feed or drinking water. Mixing and dilution must be done careful ly in order to avoid dosing mistakes. Both overdosing and underdosing can have adverse effects. Overdosing can cause drag toxicides and disruption of normal gastrointestinal flo ra. Underdosing leads to ineffective treatment (and therefore wasted dollars), and may promote the development of anti biotic resistance in bacterial populations. Drag residues in animal and poultry meat and products is an important public health issue. Drug withdrawal times before slaughter or marketing of eggs must be strictly fol lowed. Most poultry companies have stringent in-house programs to prevent any violations of drag use, and often check bird tissues for residues before slaughter to ensure that no traces of drags are present A recent issue of theFDA Vet erinarian, Nov/Dec 1994, Vol. IX, No. VI, contains a sum mary of illegal drag residues in meat for the 1993 fiscal year. The incidence of detected violative tissue drug residues listed by class of food animal shows that turkeys and chickens made up the lowest number of cases. Poultry species (7 total cases) were significantly lower than any other major food animal category including cattle (3,373), swine (345), and sheep (17). Continued responsible use by poultry producers of drags for treating poultry will help continue this enviable record. Responsible chemotherapy can be summed up this way: Use the correct drug at the correct time for the correct dura tion. Above all, don’t use a drug if you don’t need it. 5. ERADICATE. The most drastic control measure is eradication. This is a strategy to eliminate the disease from the host population. Complete eradication schemes are reserved for highly contagious and virulent diseases such as highly pathogenic avian influenza and velogenic Newcastle Disease. The highly pathogenic avian influenza (AI) virus responsible for the 1983-1984 outbreak in Pennsylvania and surrounding states was eradicated from the area by an intense and costly effort Monitoring programs involving testing of birds, environments, blood and eggs are still in place. These are considered necessary to prevent reintroduction or spread of similar Al viruses, which still persist in migrating water fowl and live bird markets, into our commercial poultry populations. Partial eradication programs, such as those included in the National Poultry Improvement Plan (NPEP), involve elimi nating certain vertically transmitted diseases from the breed er bird populations. Pullorum disease and MYCOPLASMA GALLISEPTICUM (MG) infections have been drastically reduced in our country due to the collective efforts of the poultry industry. Other nations look to these programs as models of poultry health improvement. Partial eradication requires constant disease monitoring (usually by serologic tests) and follow-up on any suspected positive birds. Depo pulation (or at least quarantine and discontinued use of hatch ing eggs) is necessary when disease breaks occur. Commer cial level birds may have sporadic problems with these con trolled diseases. Pullorum is extremely rare in most U.S. poultry, but MG is fairly common in multi-age layer flocks. Backyard flocks serve as reservoirs for most diseases. For this reason, strict biosecurity around known positive com mercial flocks and backyard flocks is necessary in order to prevent spread of the agents back to breeders. As you can see, all five control strategies Pathogen Reduction, Stress Reduction. Medication, Vaccination and Eradication are very different from each other in details and scope, but the goal remains the same. It is necessary to combine various elements of the five methods to build a sound, total health program tha) works on your poultry farm. Everyone benefits from disease control efforts including your birds, you, and the industry.
