Methods: Ninety-six cobb race chickens were equally divided in 4 groups and randomly assigned to receive a standard treatment feed + homeopathic concentrations of Symphytum (S.) officinalis (9CH), or standard treatment feed + homeopathic concentrations of Tricalcarea (4CH), or standard treatment feed + homeopathic concentrations of Calcarea (C.) carbonica (30CH) or a placebo (the same feed but without any homeopathic compound) in order to assess the ability of the homeopathic compounds to increase the concentration of calcium hydroxyapatite in the sternal spongy bone tissue. We measured the concentration of calcium hydroxyapatite in the sternal spongy bone tissue of all chickens by means of a computed tomography (CT).
Results: 30%, 36% and 63% increase of sternum spongy-bone mineralization was observed after a 2 years period in the treatment groups with S. officinalis (9CH), Tricalcarea (4CH) (*P < 0.05) and C. carbonica (30CH) (***P < 0.001) respectively.
Conclusion: Bone mineralization is usually low in battery chickens reared in commercial poultry-sheds, creating a weakness of the whole animal supporting apparatus. Homeopathic preparations with bone-tissue tropism may improve their health quality.
