| Aflatoxin* | Hepatic size
enlargement Increase in proto-combining time Pro-ventricle size enlargement Laying reduction Embryo development delay Sericeous protein reduction |
Increase in
coagulation time Corporal size reduction Gizzard size enlargement Testicle atrophia Embryo malformations Antibody absorption reduction |
| Ochratoxin A* | Kidney weight increase Increased Urate deposits biliary conducts multiplication Immunization defenses reduction |
Corporal Weight loss Sexual maturity delay Laying reduction |

| Diacetoxycirpernol* | Lymphatic tissue necropsy Biliary vesicle necropsy |
Spinal cord necropsy |
| T-2* | Mouth necropsy VII factor and proto-combining reduction |
Hepatic hypertrophy Subcutaneous edema |
| Zearalenone* | Liver weight increase Kidney weight increase Testicle intestinal fibrosis Testicle weight reduction |
Heart weight increase Estrogenic effect Crest size reduction |
| Citrinin* | Renal size enlargement Urine production increase |
Increase in water Consumption |
| Penicilloic* Acid Sterigmata-cystine | Heart muscle alteration Hepatic necropsy |
Renal necropsy |
| Penitrem A and B* | Neurotoxic | |
| Patulin | Hepatic alteration | |
| Note: The combination of two or more mycotoxins, even at LOW levels can be more toxic than one toxin at a high level and might NOT show the same symptoms as one mycotoxin. | ||

Clinical Effect
|
| Aflatoxin |
Development / grow-out
|
* Growth and feed conversion
reduction. * Liver microscopic lesions, colangio-hepatitis, hepatic serological enzymes enlargement * Feed consumption reduction, hardened hair, hypertony. * Coagulation apathy, depression, anorexia. * Acute hepatitis, and mortality in 3 to 10 days. |
| Sow / Reproductive
Stage |
* No conception effect, normal slow growing suckling pigs because of aflatoxin in the milk. | |
| Ochratoxin and Citrinin
|
Grow-out |
* Moderate renal lesions.
reduction in weight gain. * Polydypsia, reduced growth, glycosuria and polyuria |
| Sows / Reproductive Stage

when feeding * 1-3 weeks post-service. |
|
| Fumonisin |
Swine |
