Correlation between heart muscle damage and high-nutrient feed in broiler chickens

Area of Science:

• Animal Science
• Veterinary Pathology
• Poultry Nutrition

Background:

• Broiler chickens are a significant agricultural commodity.
• Optimizing broiler growth and health is crucial for the poultry industry.
• Sudden death syndrome (SDS) is a concern in broiler production.

Purpose of the Study:

• To investigate the effects of a high-nutrient broiler finisher feed on broiler chicken growth and cardiac health.
• To compare the impact of broiler finisher feed versus control feed on physiological and pathological parameters.

Main Methods:

• Broiler chickens were fed either commercial intensive growers (control) or commercial broiler finishers (high-nutrient feed) for 4 weeks.
• Body weights were monitored weekly.
• At 8 weeks, blood samples and heart tissues were collected for analysis of serum creatine kinase (CK) and histopathology.

Main Results:

• Chickens fed the high-nutrient broiler finisher feed exhibited significantly increased body weight.
• Elevated serum CK levels and significant pathological findings in heart muscle were observed in the broiler finisher group.
• Histopathological examination revealed heart muscle changes consistent with sudden death syndrome.

Conclusions:

• High-nutrient broiler finisher feed promotes increased body weight in broiler chickens.
• This feed formulation may contribute to cardiac damage and elevated CK levels, potentially leading to conditions resembling sudden death syndrome.
• Further research is warranted to understand the specific mechanisms linking broiler finisher diets to cardiac pathology.
