Runting-stunting syndrome in broilers
From Wikipedia, the free encyclopedia
Runting-stunting syndrome in broilers is a syndrome described in broilers since the 1940s, but often with specific etiological appellations (viral enteritis, malabsorption syndrome, brittle bone disease, infectious pro ventriculitis, helicopter disease and pale bird syndrome). It consists of stunted growth in birds, which is clearly visible in the second month of growth (30–42 days).
The mortality of the flock is unaffected, but a certain proportion of birds (1 to 10 percent) show decreased body weights ("runts") and elevated feed conversion. This leads to reduced uniformity of the flock.
