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.
·
Control/Prevention:
best method of control is to control coccidiosis and nematodirosis.
