By definition, early weaning is weaning calves at an age younger than ‘normal’ practice. In Queensland, the normal range of weaning is at 5–8 months though the range does extend either way by a couple of months.

In extreme cases, ‘early weaning’ (without milk replacer) can be performed safely and effectively down to 4–6 weeks of age, though calves that have reached 3–4 months are considerably easier to feed and manage.

Why wean early?

The main purpose of early weaning is the proactive management of breeding herds in times of feed scarcity or drought. During these times, late pregnancy and lactation can have a drastic effect on the body condition of cows, particularly first calf cows. The resulting severe weight loss causes low subsequent pregnancy rate, poor long term calf performance and possibly significant breeder deaths. Importantly, the latter could render producers liable for prosecution for welfare concerns under the Animal Care and Protection Act 2001.

Producers should also consider the additional damage that is being done to pastures.

In times of drought or dry years, graziers are left with the following management options:

• feed very large amounts of fodder to keep cows and calves going
• wean early and sell bobby calves
• wean early and feed calves separately to the cows.

Note: Calves weaned early must be fed and managed well.
