Show Notes

Maximise Production with Smart Calf Rearing: ShaunBalemi sits down with lactation physiologist Dr Adam Geiger to break down the calf rearing decisions that drive future milk production, first lactation performance and lifetime cow productivity. They cover colostrum management for passive transfer, how to reduce bacterial contamination in calf feeding gear, and why the first 60–90 days are important for mammary gland development and genetic potential. You’ll also hear practical guidance on milk feeding rates(including higher volumes), a slower weaning plan (7–14 days), calf starter and calf meal formulation (starch, protein, fibre targets), and why water quality testing can make or break solid feed intake. Dr Geiger explains trace mineral reducing gaps when feeding whole milk, with a focus on manganese, zinc, copper and iodine, plus vitamins like D and E, and how iron in water can interfere with mineral availability.

Key takeaways: Colostrum management is crucial for calf health and future milk production. The first 60 to 90 days of a calf's life are critical for udder development. Higher feeding rates of milk lead to better growth and health in calves. Water quality significantly impacts calf health and feed intake. Manganese is essential for hormone production and mammary growth. Calf meal formulation should balance starch, protein, and fibre for optimal growth. Testing water quality can reveal issues that affect calf nutrition. Whole milk lacks essential trace minerals and vitamins needed for calf growth. Establishing a routine in feeding helps calves adapt better to solid feed. Investing in calf nutrition can lead to better lifetime productivity in dairy cows. Key terms: Calf rearing for milk production Colostrum management dairy calves Passive transfer colostrum Mammary development first 60 days High milk feeding rates calves Calf weaning programme 7–14 days Calf starter meal starch protein fibre Dairy calf water quality testing Trace minerals for calves zinc copper iodine manganese Iron in water blocks mineral absorption calves

In this episode of the myCOW podcast, Shaun Balemi looks at the visual cues springer cows, colostrum cows, and fresh cows can give farmers about stress, feed balance, metabolic health and recovery after calving. Shaun explains what to look for in the paddock, from rumen fill, appetite and manure consistency to unusual posture, jumpiness, isolation from the herd, dehydration and changes in feeding behaviour. He covers how hunger, feed access, weather, competition and mineral balance can affect cow behaviour and what these signs may suggest about what is happening before and after calving. He also discusses how visual observations can be used alongside blood results, milk data and cow wearable information to build a clearer picture of cow performance. Shaun explains what good recovery can look like in the colostrum mob, including strong appetite, good rumen fill, rumination, consistent manure and cows actively eating, drinking or resting comfortably. Takeaways: What visual signs can indicate stress in springer and colostrum cows How rumen fill and appetite can help assess feed intake What jumpiness, unusual posture and isolation from the herd may indicate How feed competition and water access can affect cow intake What condition loss and inconsistent manure can suggest about diet balance How tremors, pica and low energy may relate to mineral or metabolic imbalance What sunken eyes can tell you about dehydration What to look for in cows recovering well after calving How visual observations can be considered alongside blood, milk and wearable data

In this episode of the myCOW podcast, Shaun Balemi looks at how blood testing can help farmers understand what is happening in springer cows, colostrum cows and milkers through transition and early lactation. Shaun explains when to collect blood samples, which cows to test and what different blood markers can tell you about mineral balance, liver function, condition loss, oxidative capacity and inflammation. The episode covers calcium, magnesium, phosphorus, NEFA and BHB, along with other measures such as haptoglobin, albumin, cholesterol, GPX and vitamin E. He also discusses how blood results can be used to assess DCAD balance, mineral supplementation, condition loss and cow recovery after calving. Shaun explains why blood data is most useful when considered alongside cow numbers, rumination, body condition, wearable data and other information from the herd. Takeaways: When to blood test springer cows, colostrum cows and milkers How to select cows for representative blood testing What calcium, magnesium and phosphorus results can tell you How NEFA can indicate the amount of body condition cows are mobilising How BHB can help assess how the liver is handling mobilised fat What blood results can show about transition and early lactation nutrition How oxidative capacity and inflammation can be assessed through blood testing Why cow data should be considered alongside blood test results How blood testing can support discussions with vets, nutritionists and rural advisers

In this episode of the myCOW podcast, Shaun Balemi looks at how feed and herbage testing can help farmers plan springer cow diets and improve transition outcomes. Shaun explains what to test, when to collect samples and how to interpret results across energy, protein, fibre, DCAD, major minerals and trace minerals. The episode covers practical sampling methods, how weather and feed wastage affect actual intake and why test results need to be considered alongside cow appetite, rumination, behaviour and body condition. He also discusses using feed data to select springer paddocks, balance pasture and supplementary feeds, manage potassium and calcium levels and plan mineral supplementation before calving. Takeaways: What information farmers can gain from feed and herbage testing When to sample springer paddocks, silage and supplementary feeds How to collect and handle representative samples How energy, protein and fibre affect transition cow diets Why DCAD and mineral balance matter before calving How potassium levels can guide springer paddock selection Why feed data should be assessed alongside what cows are showing How feed testing can support discussions with vets, nutritionists and rural advisers Keywords: Springer cows, feed testing, herbage testing, transition cow nutrition, feed data, DCAD, mineral balance, pasture testing, metabolic disease, dairy cow performance.

What does a successful transition look like, and how can farm data help you see whether cows are on track? In the first episode of our new series about using springer and transition cow data, Shaun Balemi outlines six measures of transition success: Body condition Liver and rumen health Metabolic disease Immune function Early peak milk Reproductive performance Shaun also looks at the growing amount of information available from cow wearables, milk records, blood testing, pasture data, body condition scoring and walk-over weighing. He explains why individual figures rarely tell the full story, and how combining data can help farmers better understand changes in appetite, rumination, milk production, feed quality and cow recovery. The episode also sets up the coming series, covering: Herbage and feed data Blood testing and liver function Visual observation in the paddock Rumination data Sensor and camera technology Post-calving measures of transition success Feed conversion efficiency

In this episode of the myCOW podcast, Shaun Balemi and Ben Matthews talk with Baden from ProTag about how smart livestock wearables could change the way New Zealand dairy farmers understand their cows. ProTag is developing a lightweight smart ear tag that combines cow behaviour data with GPS location, giving farmers a clearer view of what is happening across the herd. The conversation covers rumination, grazing behaviour, heat detection, lameness signals, pasture use, cow movement, social behaviour and how location data can make wearable technology more useful on pasture-based farms. Baden shares how ProTag was developed, why the ear was chosen as the best place to collect data and how wearable technology could help farmers make better decisions around herd health, reproduction, feed use and farm management. Takeaways: Why GPS adds important context to cow behaviour data How smart ear tags can help track grazing, rumination, movement and resting What cow location can tell farmers about pasture use and mob behaviour How wearable data may support heat detection, lameness monitoring and drafting Why New Zealand-built farm technology matters for pasture-based systems How future data could help farmers better understand cow efficiency and feed intake Listen now to hear how livestock wearables are moving beyond activity tracking and opening up new possibilities for dairy farm management.
