Blood Spot in Egg Albumin

Correct Answer: Haemorrhage in magnum

When a blood spot is found in the albumin (egg white), it indicates haemorrhage that occurred in the magnum — the part of the oviduct where albumin is secreted.

Blood Spot Diagnosis Summary

• Blood in yolk → Ovary or infundibulum haemorrhage
• Blood in albumin → Magnum haemorrhage

Oviduct Sequence (for Reference)

1. Infundibulum: collects yolk (15 min)
2. Magnum: secretes albumin (3 hours) ← blood here → blood in albumin
3. Isthmus: shell membranes (1h 15 min)
4. Uterus: shell & pigment (21 hours)
