| Summary | Amaferm resulted in a 12% increase in 4% FCM in early lactation and a 3.7% increase in 4% FCM for the total experimental period (0-120 DIM), with similar feed intakes as controls. Greatest response was when the ambient temperature was above 32.2°C, Amaferm increased (P < .05) respiration rate and rectal temperature in early lactation and overall. However, respiration rate and rectal temperature were not different in later lactation (61-120 DIM). |
