“…Crypt depth was also influenced by particle size (p ≤ 0.038); larger particles promoted deeper crypts. These data are in accordance with the studies that show that the type and the size of the food that is ingested may change the characteristics of the intestinal mucosa, causing ulcerations, haemorrhages or affecting villus height and crypt depth (Franti et al, 1972;Harry et al, 1975); Dibner et al, 1996).…”

The objective of this experiment was to investigate the effects of different particle sizes, expressed as Geometric Mean Diameter (GMD) of corn (0.336mm, 0.585mm, 0.856mm and 1.12mm) of mash and pelleted broiler chicken diets on the weight of the gizzard, duodenum and jejunum+ileum; on the pH of the gizzard and small intestine and on the characteristics of the duodenal mucous layer (number and height of villi and crypt depth) in 42-day-old broilers. The physical form and the particle size of the diet had no significant effect on gizzard and intestine pH (p > 0.05). A greater gizzard weight was seen in the birds receiving pelleted diet and particle size of 0.336mm (p ≤ 0.008). However, for the particle sizes of 0.856 and 1.12 mm, a greater weight was found in birds that received mash diet (p ≤ 0.039 and p ≤ 0.006, respectively). Also, gizzard weight was greater with increasing corn GMD independent of the physical form of the diet. In the mash diet, the increase in particle size promoted a quadratic response in the weight of duodenum and jejunum + ileum. The pelleted diet promoted a greater number of villi per transverse duodenum cut (p ≤ 0.007) and greater crypt depth (p < 0.05). As the particle size increased, there was a linear increase of villus height and crypt depth in the duodenum, irrespective of the physical form of the diet.

“…Spontaneous gizzard erosions are common in broiler chickens, but the cause is difficult to pinpoint because of the many potential causes, including histamine, 11,12 fish meal, 15 gizzerosine, 19 mycotoxins (T-2, 27 cyclopiazonic acid, 3 tenuazonic acid 5 ), vitamin deficiencies, 2 and bacterial complications. 4 A low concentration of deoxynivalenol (DON, vomitoxin) was identified in poultry feed used in this study but was considered insignificant because no lesions developed in the control chickens fed the same feed.…”

Abstract. Adenoviruses and reoviruses isolated from commercial broiler chickens were evaluated for gastrointestinal pathogenicity in specific-pathogen-free Leghorn chickens. The viruses were originally isolated from either the proventriculus or a gastrointestinal pool of tissues of broiler chickens with proventriculitis or enteritis. Isolates were cloned by terminal dilution. Day-old chickens were inoculated by oral and ocular routes with undiluted tissue culture fluids (titers of 10 2 -10 4 TCID 50 /ml) and then examined at necropsy on days 5, 10, and 15 postinoculation. Chickens in all virus groups (but not the control group) developed wet, unformed fecal droppings that persisted for the duration of the study. Mild lesions occurred in reovirus-inoculated chickens and included hyperplasia of lymphocyte aggregates in various organs and mild gizzard erosions. Chickens inoculated with adenovirus isolates developed marked gizzard erosions and necrotizing pancreatitis as well as mild proventriculitis. Intranuclear viral inclusion bodies occurred in gizzard epithelium and pancreatic acinar cells at the sites of lesions. Lymphocytic atrophy occurred in the bursa of Fabricius. Respective viruses were reisolated from proventriculus and duodenum collected from chickens of each group; no viruses were isolated from controls. Under the conditions of this study, adenovirus isolates were more pathogenic than the reovirus isolates in the digestive system.Digestive system signs and lesions often are observed in broiler chickens submitted for laboratory evaluation because of impaired weight gain and feed conversion, feed passage, and watery feces. Various lesions have been identified in the proventriculus, gizzard, intestines, pancreas, and liver in the course of these investigations. Adenoviruses and reoviruses are commonly isolated from the affected viscera, particularly from the proventriculus and duodenum in birds with lesions in these organs.Digestive tract disease in broiler chickens in the southeastern United States has several causes and clinical and pathologic expressions. 7 Reoviruses have a causative link with digestive syndromes, but mainly these syndromes are caused by certain reovirus strains of high pathogenicity. 23 The role of adenoviruses in digestive disease of chickens is equivocal, 18 which has made it difficult to interpret virus isolation results from chickens with digestive system signs and lesions.The purpose of this study was to extend routine diagnostic investigation of digestive tract disease by attempting to assess the pathogenic potential of viral isolates in susceptible chickens.

“…In broiler chicks occurrence of gizzard erosions has usually been associated with high levels (7 to 25%) offish meal in the feed (Janssen, 1971;Johnson and Pinedo, 1971;Halama, 1973;Harry and Tucker, 1975;Kubena et al, 1976;Lu et al, 1982;Umemura, 1982;Okazaki et al, 1983). Umemura (1982) induced gizzard erosions experimentally in broiler chicks by feeding them mackerel rrieal heated at 135 C C for 3 hours.…”

“…In broilers the condition may lead to increased mortality or to depression of growth (Janssen, 1971 ;Johnson and Pinedo, 1971 ;Halama, 1973;Lu et al, 1982), but occasionally the only effect is an increased number of gizzards found to be unfit for human consumption at meat inspection (Janssen, 1971). In most field outbreaks in broilers the gizzard erosions have been associated with the inclusion of fish meal of presumed inferior quality in the diets (Janssen, 1971-Johnson andPinedo, 1971;Halama, 1973;Harry and Tucker, 1975).…”
