The objectives of the present study were to examine the effects of repeated or chronic ochratoxin A (OA) and citrinin exposure, and to determine if severe ochratoxicosis permanently alters renal function in pullets. The OA-treated birds were injected intramuscularly (breast muscle) with a 1 mg/mL solution of OA at a dose of .25 mg/kg BW or .5 mg/kg BW. Citrinin-treated birds were injected with a 6 mg/mL solution of citrinin at a dose of 6 mg/kg BW. Control birds received an equal volume injection of the citrinin and OA solvent, 100% ethanol, at a dose of 1 mL/kg BW. Kidney function was evaluated after 10 consecutive days of OA, citrinin, or ethanol injection, and 2 wk following the final injections. Venous blood gas measurements were taken after the seventh day of injection. The OA increased urine flow rate, decreased urine osmolality, increased ion excretion (Na, K, Ca, P), increased water consumption, increased manure moisture, and caused a relative alkalosis when measured immediately after 10 days of OA injection. These effects of OA were not detected 2 wk later. Citrinin increased manure moisture, decreased plasma P, increased the clearance of para-aminohippuric acid, and had no consistent effect on blood acid-base parameters. The results suggest that OA may cause an osmotic diuresis by inhibiting tubular reabsorption of electrolytes. The data also suggests that the effects of OA may be reversible simply by discontinuing toxin administration. Although the citrinin-induced increase in manure moisture indicates that citrinin had an effect on renal function, renal function analysis suggests that even repeated exposure to high doses of citrinin may only have a short duration of diuretic action on the kidneys.

The toxic effects of citrinin in turkeys and ducklings was studied in four trials. Citrinin dissolved in dimethyl sulfoxide-70% ethanol solution (3:1, volume/volume) was administered by gavage to male turkey poults and male white Pekin ducklings. When seven-day-old ducklings were given doses of citrinin between 30 to 110 mg/kg body weight, most of the treated ducklings which died (49/80) did so within four to 12 hours. Blood samples were collected sequentially at 3, 6, 12, and 24 hours after administration from seven-day-old ducklings given the single lethal dose (LD50). The alterations included hyperkalemia (P less than or equal to 0.01) and metabolic acidosis characterized by reduced blood pH (P less than or equal to 0.01) and base excess (P less than or equal to 0.01). Fourteen-day-old turkeys and ducklings given 56 or 57 mg/kg, respectively, were killed at 1, 3, 6, 12, 24, 48, and 72 hours after treatment. The principal alteration in both species was nephrosis that was more severe in turkeys than in ducklings. Tubular necrosis was the dominant lesion at three to 72 hours in turkeys and at six to 24 hours in ducklings. Hepatic and lymphoid lesions occurred in both turkeys and ducklings treated with citrinin.

Citrinin fed to mature laying hens at levels of 0, 50, and 250 mug/g. of diet for three weeks had no effect on body weight, feed consumption, egg production, egg weight or egg shell quality. A moderate diarrhea occurring about three days after feeding 250 mug. citrinin/g. of diet was observed. However, the diarrhea subsided once the birds were returned to a normal diet. Young broiler chicks were fed a diet containing either 0, 62.5, 125, 250, or 500 mug. citrinin/g. of diet from hatching to three weeks of age. Body weight was decreased by the 500 mug/g. level whereas all levels of citrinin resulted in enlarged kidneys and an improvement in feed conversion when compared to control values. There was also a slight dose-related increase in liver size. The 250 and 500 mug./g. levels resulted in a dose-related increase in water consumption accompanied by an acute diarrhea. Dietary citrinin had no effect on serum protein, glucose, cholesterol, uric acid, calcium, potassium and sodium concentrations or packed cell volume.

Dietary levels of citrinin of 62.5, 125 and 500 mug./g. diet or aflatoxin at a dietary level of 2.5 mug./g. of diet fed from 1-21 days of age did not inccrease the incidence of leg problems compared to control groups receiving no dietary nycotoxins. These data indicate that dietary contamination with these toxins does not account for the incidence of occasionally observed leg probelms in younger broiler chicks.
