Nutrient absorption and changes in blood plasma of stunted broilers

M D Ruff

    Avian Diseases
    |October 1, 1982
    PubMed
    Summary

    Stunted broiler chickens exhibit paleness and poor feathering, with altered plasma protein and decreased pigment. Pancreas bleaching was observed in nearly half of affected birds, indicating a complex physiological impact.

    Area of Science:

    • Avian pathology
    • Poultry science
    • Veterinary medicine

    Background:

    • Broiler chickens can suffer from conditions with various names like infectious stunting syndrome, pale bird syndrome, malabsorption syndrome, and helicopter disease.
    • These syndromes are characterized by high mortality, stunting, and leg weakness in affected birds.
    • A control group of healthy broilers from a separate farm was used for comparison.

    Purpose of the Study:

    • To investigate the clinical and pathological characteristics of a stunting syndrome in broilers.
    • To identify physiological and biochemical differences between stunted and normal-sized broilers.

    Main Methods:

    • Broilers exhibiting stunting syndrome were collected from three affected farms.
    • A fourth farm with healthy broilers served as a control group.
    • Clinical signs, gross lesions, and biochemical parameters (plasma protein, pigment, glucose, liver glycogen) were analyzed.

    Main Results:

    • Stunted broilers showed paleness, poor feather development, and broken feather shafts.
    • Pancreas bleaching occurred in 47% of stunted broilers.
    • Stunted birds had increased plasma protein (specifically alpha, beta 1, gamma 1, and gamma 2 globulins) and decreased plasma pigment compared to controls.

    Conclusions:

    • The stunting syndrome in broilers is associated with specific clinical signs and pathological findings, including pancreas bleaching.
    • Significant alterations in plasma protein and pigment levels suggest systemic physiological disturbances.
    • Further research is needed to elucidate the exact causes and mechanisms underlying this syndrome.
