Electrocardiograms (EKGs) can help predict ascites in broilers raised at high altitudes. Significant EKG changes, like increased S wave amplitude, were observed in affected birds by day 14.

Area of Science:

  • Veterinary Medicine
  • Animal Physiology
  • Avian Health

Background:

  • Ascites syndrome is a significant concern in broiler production, particularly under high-altitude conditions.
  • Early detection of ascites is crucial for effective management and reducing economic losses in poultry farming.

Purpose of the Study:

  • To investigate the potential of electrocardiograms (EKGs) for predicting ascites in broilers reared at simulated high altitude.
  • To identify specific EKG parameters that correlate with the development of ascites.

Main Methods:

  • Three replicate experiments were conducted with 100 broilers each, reared at 3000 meters simulated altitude or ambient pressure.
  • EKGs (Leads I, II, III) were recorded on days 0, 14, 28, and 42.
  • Packed cell volume and body weight were also measured.

Main Results:

  • On days 14 and 28, broilers developing ascites showed significantly higher S wave amplitude and QRS complex amplitude compared to controls.
  • Birds at simulated high altitude consistently had higher packed cell volumes.
  • Ascites group birds exhibited significantly lower body weight from day 14 onwards.

Conclusions:

  • EKG parameters, specifically increased S wave and QRS complex amplitudes, show promise for early prediction of ascites in high-altitude reared broilers.
  • Elevated packed cell volume and reduced body weight are also indicators associated with ascites development under these conditions.
