Weighting factors for each clinical observation^a

Parameter	Clinical sign(s) of respiratory disease at rectal temp of:
	<39.5°C	39.5-40.5°C	>40.5°C
Ocular discharge or runny eyes	None	Serous or mucous	Purulent or hemorragic
Nasal discharge	None	Serous or mucous	Purulent
Coughing	None	Spontaneous	Spontaneous and productive
RR (breaths/min)	≤60	60-100	>100
Respiratory distress	None	Dyspnea
	Costoabdominal	Exaggerated intercostal and/or abdominal effort
	Regular breathing	Irregular breathing
Respiratory noise	None	Abnormal or intense respiratory sound (stridor)
Trachea sensitivity	No induced cough after moderate pressure on trachea	Induced cough after moderate pressure on trachea at one particular place	Induced cough after moderate pressure on trachea on more than one place
Lung auscultation	No abnormalities	Abnormal left or right lungs	Abnormal both right and left lungs
		Increased intensity	Vesicular lung sounds
Scoringb	0	1	2

^aThe severity of the clinical disease was expressed by allocating a weighting factor (0, 1, or 2) for each mentioned observation (first column). For example: if the rectal temperature is <39°C, the weighting factor is 0; if the rectal temperature is >39°C but ≤40.5°C, the weighting factor is 1; if the rectal temperature is >40.5°C, the weighting factor is 2.

^bScoring values per observed observation. The total score was calculated by editing the weighting factors for each observation.
