Table 8. Poisson regression for days with abnormal appearance (≥2)¹, frequency and duration of diarrhea (≥3)² and pneumonia, and days with medication before weaning (d 1 to 60) as influenced by feeding pasteurized waste milk (WM) and a blend of WM with milk replacer powder (WM+MR) or transition milk (WM+TM) as liquid feeds to cold-stressed newborn Holstein calves (n = 17 per treatment).

¹1 = normal and alert; 2 = ears drooped; 3 = head and ears drooped, dull eyes, and slightly lethargic; 4 = head and ears drooped, dull eyes, and lethargic; and 5 = severely lethargic; based on the scoring system described by [56].

²1 = normal; 2 = soft to loose; 3 = loose to watery; 4 = watery, mucous, and slightly bloody; and 5 = watery, mucous, and bloody; based on the scoring system described by [56].

³Contrasts: C1 = WM vs. the average of WM+TM and WM+MR; C2 = WM+TM vs. WM+MR.
