Nephrosis in Lambs
Occurs sporadically in young lambs between 2 – 4 weeks old and in growing lambs between 2 – 4 months old; cases in the latter age group often appear after an outbreak of coccidiosis and/or nematodirosis. The cause has not been resolved although a toxic insult is considered the probable cause.
Clinical signs: are recognised as lambs being depressed, not nursing and appear thirsty as they frequently stand with their heads over a water trough but do not drink a lot. Also, a gaunt appearance with little abdominal content and rapid emaciation is seen. Rectal temperature is normal. Often evidence of faecal staining of the perineum. Faeces are soft and malodorous.
Differential Diagnosis: coccidiosis, nematodirosis, starvation, hepatic necrobacillosis, chronic suppurative pneumonia or chronic peritonitis.
· Diagnosis: based on clinical findings and results of tests may by vets. Necropsy will reveal very pale swollen kidneys. Lambs unresponsive to anthelmintic/anticoccodial/antibiotic therapy should be culled.
