Abstract
This chapter presents the details about clinical history, causative agent, clinical signs and lesions, transmission route, diagnostic tests, differential diagnosis, and prevention and control of cardiovascular diseases that include dilated cardiomyopathy, pulmonary hypertension syndrome, aortic rupture/dissecting aneurysm, round heart disease, nutritional and toxic cardiopathies, and infectious cardiopathies. There are a number of differences between the avian and the mammalian heart, some of which have clinical implications in the pathophysiology and diagnosis of poultry cardiovascular diseases. Electrocardiography (ECG) is invaluable to investigate conduction disorders and arrhythmia. Common ECG abnormalities in chickens include mean QRS axis deviation, ventricular premature contractions, and atrioventricular blocks. Ascites/pulmonary hypertension syndrome is one of the most common causes of mortality in commercial flocks of broilers, with an average prevalence of approximately 4.7%, which can go as high as 15-20% in certain roaster chicken flocks. Younger poultry birds are more commonly affected by nutritional deficiencies and excess.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
