Histopathological changes in ewe lambs exposed to prolonged diet on lucerne.

Histopathological changes were observed in 10 ewe lambs reared during nine months on lucerne as compared with 10 controls reared on ryegrass. These changes consisted of periglandular oedema and subacute endometritis in the uterus, secretory-cell hyperplasia with prevalence of neutral mucopolysaccharides in the cervix and hyperkeratinisation and colpitis in the vagina. The mammary glands of lambs reared on lucerne were significantly heavier and showed secretory activity.
