As spring calving progresses and labour demands increase, it becomes more challenging to maintain close observation of young calves. However, this is precisely when attention to detail matters most. Early identification of sick calves is critical — not only to safeguard the individual animal’s performance, but to prevent disease spread across the shed.
At Terra NutriTECH, we work alongside farmers to strengthen calf health protocols, improve early-life nutrition, and support on-farm systems that reduce labour pressure while protecting performance.
Early Identification: The Foundation of Calf Performance
Calves should be monitored multiple times daily, with morning and evening feeds serving as key health checkpoints.
Healthy calves should:
- Be bright, alert and responsive
- Have perky ears and a strong suck reflex
- Rise quickly at feeding
- Show consistent appetite and activity
Warning signs that require immediate attention include:
- Slow or reluctant rising at feeding
- Sunken eyes (dehydration)
- Elevated heart rate
- Heavy or laboured breathing
- Swollen or inflamed navel
- Nasal discharge
- Loose or inconsistent faeces
- Isolation from the group
Calves often separate themselves when unwell, lying in corners or away from pen-mates. Prompt action is essential.
Isolation and Immediate Intervention
Any calf showing symptoms should be moved immediately to a designated isolation or recovery pen.
Best practice includes:
- A clean, dry, well-bedded pen
- Access to fresh water and appropriate nutrition
- An infra-red heat lamp to reduce energy loss
Providing supplemental heat prevents the calf from expending energy maintaining body temperature while fighting infection. This supports faster recovery, encourages feed intake, and reduces long-term setbacks in growth and performance.
The Labour Challenge During Peak Calving
During peak calving, calf health can unintentionally slip due to:
- Larger group housing
- Batch feeding systems
- Increased focus on milking herd health
- Less experienced relief staff managing calf care
While automatic calf feeders can monitor milk intake, drinking speed, and visit frequency, technology should complement — not replace — physical inspection.
At Terra NutriTECH, we help farms implement structured calf health protocols and nutritional programmes that reduce reliance on reactive treatment and instead promote proactive health management.
Colostrum: The First and Most Important Investment
Calf immunity begins at birth. Calves are born without natural immunity and depend entirely on antibodies absorbed from colostrum.
To maximise immunity transfer, we strongly advocate the 1-2-3 Colostrum Rule:
- 1 – Feed within 1 hour of birth
- 2 – Feed 2 litres minimum at first feeding
- 3 – Deliver at least 3 litres within the first 6 hours
Absorption efficiency declines rapidly:
- Maximum absorption occurs within 2 hours
- Reduced by 50% at 6 hours
- Significantly limited after 24 hours
Excess high-quality colostrum should be frozen and stored to ensure availability later in the season when quality may decline.
