CONSISTENT MILK TEMP IS KEY
When healthy calves are fed fresh milk, ensuring a consistent temperature from day-to-day is more important than the actual temperature, says Dr Andrews.
Although fresh milk fed at blood temperature is ideal, it is not essential, he claims. But milk temperatures below 10C (50F) would reduce intakes.
He warns against increasing the temperature quickly with hot water, as that can prevent milk clotting in the stomach.
Milk stored for up to two days contains more lactic acid, he says, and lactobacilli bacteria (found in pro-biotics), which have a beneficial effect. This is useful because bugs in the gut find it more difficult to multiply when conditions are more acidic.
Makers instructions must be followed when offering milk substitute.
