“…In the literature GEU appears mainly as a problem in chickens (Fossum et al, 1988;Pfeiffer, 1992), and above all in broilers (Johnson & Pinedo, 1971;Janssen & Germs, 1973;Okuda et al, 2004;Novoa-Garrido et al, 2006). GEU in young turkeys has very rarely been described in the scientific literature (Sherwood & Sloan, 1954;Fletcher & Abdul-Aziz, 2008), although it is well recognized as sub-lethal lesions, as a cause of sporadic increase in mortality, and as a cause of gizzard condemnation at slaughter in Norway (unpublished data from our laboratory and from the Norwegian Food Safety Authority).…”

“…Studies on the effect of experimental vitamin B 12 deficiency on GEU have produced contradictory results (Mushett & Ott, 1949;Sherwood & Sloan, 1954;Daghir & Haddad, 1981). Sherwood & Sloan (1954) found a protective effect against GEU in turkeys of choline, and Daghir & Haddad (1981) detected a significant increase in GEU severity among vitamin B 6 -deficient chickens. The severity of GEU among vitamin B 6 -deficient chickens was reduced by adding taurocholic acid to the diet.…”

Gizzard erosion and ulceration syndrome (GEU) was described for the first time in the 1930s. The main focus of early studies was on nutritional deficiencies and peroxidation of highly polyunsaturated fatty acids as causative factors. During the 1970s and 1980s the focus was moved towards toxic substances in the feed. Scott's review in 1985 concluded that overproduction of gastric acid induced by gizzerosine was a major cause of GEU. During the last decades, serotype 1 of fowl adenovirus A and Clostridium perfringens have been implicated as important pathogenic agents in the development of GEU in chickens. Although GEU is globally distributed and its subclinical form appears to be common in commercial poultry flocks, the condition is rarely mentioned in standard textbooks on poultry health. This regrettable fact is probably due in part to the lack of one definitive cause of the syndrome.

“…A level of 2.5 meg vitamin B12 per kilogram of ration almost completely prevented the gizzard disorder in chicks from hens fed a commercial breeder ration, while 10 meg were required for a similar effect in chicks from hens fed an all-vegetable ration. Sherwood and Sloan (1954) studied the effect of vitamin B12» choline and methionine on gizzard erosion in Broad Breast ed Bronze poults. Vitamin B12 did not have a consistent ef fect on gizzard erosion, but choline reduced gizzard erosion when added to the ration and also produced relatively smaller gizzards.…”

Six experiments have been completed on day-old male cross-bred chicks for periods of up to 2 and 4 weeks to learn more about the role of pyridoxine in the etiology of gizzard erosion. At the end of each experiment, chicks were sacrificed and their gizzards removed and scored for the severity and incidence of erosion. The results of these experiments confirm the previous finding that the severity and incidence of gizzard erosion is increased by B6 deficiency. They further show that taurocholic acid, at 1% of the diet, had a protective effect against this erosion. Feeding B6-adequate rations to chicks that previously had been fed a B6-deficient diet led to partial healing of gizzard erosions. Results also indicate that the feeding of purified diets to growing chickens produces a higher incidence of erosion than that of practical-type diets. Texture of the diet did nt influence the incidence of the erosion, because grinding a practical diet to the same fineness as a purified diet did not increase gizzard erosion. Pair-feeding experiments showed that gizzard erosion in partially starved chicks was not a specific result of anorexia but of deficiencies in certain nutrients, one of which is vitamin B6.
