FEED and water shortages are likely as we move into summer, so consider weaning your beef calves early to save on requirements.
Agriculture Victoria livestock industry development officer Dr. Hannah Manning highlights the benefits of early weaning for both cows and calves. Early weaning can help cows maintain condition and fertility while setting up the calves to receive the nutrition they need to thrive.
“Lactating cows require a large amount of energy. It’s more efficient to convert feed directly into calf weight than milk for a cow and calf unit,” Dr. Manning explains.
She further emphasizes, “Providing the appropriate diet to a mob of dry cows and weaned calves, rather than cows with calves at foot, can significantly reduce feeding costs.”
Dr. Manning also points out the water consumption difference between lactating cows and dry cows. “Cows making milk need up to 100 litres of water a day, and those not feeding a calf require less. Weaning early not only benefits the calves but also reduces the cow’s water requirements.”
She advises, “In most cases, calves should be weaned at around 120 kg for easier feeding. The younger the weaning age, the higher the energy and protein requirements of the calves.”
“Setting your calves up for success is crucial,” Dr. Manning stresses. “Exposing them to post-weaning supplements while they are still on the cow is recommended for optimal growth and development.”
She adds, “Post-weaning supplements should be introduced gradually via creep-feeding, and calves should be vaccinated two weeks before weaning to protect against clostridial diseases.”
Dr. Manning cautions against combining stressful procedures like castration and dehorning with early weaning. “Weaners can be challenging to manage, so ensuring proper nutrition and supervision is essential for their well-being and growth,” she advises.
