Singletary Department of Veterinary Science Crop mycosis might be consid ered die forgotten disease. Why? Because many of the original reports on the disease are from the 1920 s and the most “cur rent” reports are from the 19605. This common health problem does not receive as much attention as it should from poultry producers and researchers. One author states that mycosis of the digestive tract probably occurs rather frequendy, but in many cases does not appear to be of sufficient significance to be considered seriously. Unfortunately, poultry diagnos tic laboratories may not report crop mycosis as a primary disease prob lem, too often considering it to be a minor or secondary condition. As its name indicates, crop mycosis is a fungal infection affecting primarily the crop and caused by the organism Candida Albicans. The mouth, esophagus, proventriculus, and the small intestine may also be affected. Young turkeys are particularly susceptible, but chickens, both broilers and layers, can experience the disease too.

These conditions along with the use of high levels of broad spectrum anti biotics have been implicated in mycosis problems. The poor man agement conditions allow the fun gus to proliferate while the antibio tics reduce the growth of competi tive bacteria. The reason crop mycosis may be overlooked and not easily recog nized in a flock is that affected birds do not have any specific characteristic symptoms. In fact, the symptoms of crop mycosis are seen with many poultry health problems and, in general, may be of little help in making a diagnosis. Symptoms include ruffled feath ers, unthrifty appearance, listless ness, and paleness. Severely infected birds may be stunted and undersized. As one would expect, the prim ary lesion is found in the crop. Normally the crop is thin walled and transparent. When infected with C. Albicans, it becomes thick ened and covered with white raised areas of mold growth. The dis eased areas should not be confused with feed or mucus in the crop. S.G.

Andrew Stair, a registered Angus breeder from Sunbright, Tenn., is the new president of the 24,000-member American Angus Association with headquarters here. Stair, who served six years as a member of the board of directors of the American Angus Associa tion and a seventh last year as vice president, was elected by a unani mous vote of the 229 delegates which can be flushed out with water, whereas the mold growth adheres to the lining of the crop. When the mold growth is scraped off, a sore, irritated area is evident. Although its effectiveness has been questioned, the most com mon and popular treatment for crop mycosis is the use of copper sulfate in the drinking water. A number of commercial products are available. However, medicat ing directions must be carefully followed to avoid toxicity prob lems. We have seen turkey poults killed because of overdosing with this drug. For feed treatment, the most effective drug is nystatin (mycostatin). A seven to ten day treatment at 100 gm per ton is recommended to control crop mycosis. Crop mycosis is a disease which seems to get little respect. Although it can be a primary health problem, it can also be a warning of other health and management problems. Therefore, whenever it is a problem in a flock, a close examination of management prac tices and other flock health prob lems should be made.
