Poultry Pointers (Continued from Page C 2) high early mortality in Pennsylva nia guinea fowl. Control of these viral enteritis suspect conditions is at present limited to attempts to drastically reduce the numbers of viral parti cles in the birds’ environment Stringent cleaning and disinfec tion procedures, increasing “down time” of facilities between flocks, single-age flocks, and in some cases, raising birds on wire have all been tried to break the cycle of infection. Feed factors implicated in altered structure or function of the GI tract are many. Inclusion of copper sulfate in the feed at higher levels is asso ciated with so-called “proventricu litis” in broilers. In this condition, proventriculi are enlarged, flaccid, and tend to rupture easily during processing. Erosions on the gizzard lining are also present Other factors such as infectious agents (viruses) and genetic predisposition are also being researched as components of this syndrome. Compounds known as biogenic amines can be found in poultry feed ingredients such as fishmeal, soybean meal, com screenings, fat and vitamin mixes. Experimentally, these histamine and histamine-like compounds can cause damage to the gizzard lining with erosions and hemorrhage, as ll 9?ißßawa»n 9P«Hanram fPiiaaaraia ywawm 32MMBBH g i g I i s R | C ¥?mmwmE | Loop Stalls Are Constructed Of; I ji *2 3/8” Outside Diameter High Yield Steel Tubing B y With Al 2 Gal.

Mycotoxins such as tri chothecenes and cyclopiazonic acid can cause similar changes. Other mycotoxins can directly or indirectly cause symptoms of malnutrition. Aflatoxin has many systemic effects on the chicken that result in decreased ability to digest nutrients and increased eli mination of nutrients. For example, the synthesis of several pancreatic digestive enzymes are repressed by aflatoxin leading to a dramatically decreased digestive ability com pared to that of a normal bird. Fewer vitamins, proteins and fats are available to the bird, and decreased growth, poor skin pig mentation, and suboptimal feath ering result. In this limited space we have described but a few of the possible causes of GI dysfunction in poultry. On a practical level, any and all practices aimed at using high qual ity feed ingredients and preserving that quality through processing and storage of feed will impact on what finally reaches Ihe bird’s GI tract. Consistency of the feeding program, especially as it relates to avoiding abrupt changes of feed or feeding schedules, is also important Clinical signs of suspected GI disease in the flock should be investigated promptly. Many GI tract symptoms are non-specific and confusing. A thorough diagnostic laboratory work-up of affected birds is essen tial to find the cause or causes of • Chip Resistant • Resists Acid & Chemicals • Smoother Finish Stays Cleaner Venango County Fair The 1994 Venango County Fair Premium List and Program is available at the agricultural exten sion office located on the Fair grounds near Franklin.

A $35 first prize will be given to the win ner in the cake contest and the cake will be eligible to be entered the problem. A longer term inves tigation of multiple flocks may be necessary to sort out confounding factors that may be present in the field. Remember, an accurate diagno sis is essential to take the guess work out of pro-active control of GI problems in future flocks.
