Flowers: Golden yellow, blue, white or pink. Fragrant and borne at the ends of branches.

TOXIC PRINCIPLE:
Cyclic hexapeptides. Phomopsin A – the principle toxin. Relatively stable toxin. |

SYNDROMES:
Hepatogenous photosensitivity primarily due to liver parenchymal damage. |
en |

SYSTEMS AFFECTED:
Liver. |

CLINICAL SIGNS:
Acute lupinosis:
• Sheep become sick in 2-3 days after lethal dose and die in 4-8 days.
• Anorexia
• Ruminal stasis• Constipation• Weakness• Icterus - Photosensitivity rare, but occurs
Chronic syndrome:
• Same as above, plus weight loss. |

NECROPSY:
Macroscopical findings:
1. Hepatosis
Acute: white (also orange-yellow) swollen, fatty liver
Chronic: markedly atrophic (especially left side, so-called boxing glove liver) fibrotic, nodular regeneration
2. Icterus
3. GI stasis. |

HISTOPATHOLOGY:
• Fatty degeneration, cholestasis
• Anisonucleosis, megalocytosis, multinucleation and nuclear vesiculation. |
