Important Information

  • FEEDING GUIDELINES

    Always use clean and disinfected compartment type feeder systems.
    Do not mix and store made-up milk. Use immediately and discard unused milk.

    Always provide clean and fresh water in low to the ground troughs.

    Feeding Rates

    Feeding rates detailed below are provided as a guide and are based on a calf with a birth weight of 40kg. For larger calves or higher target growth rates the amount of liquid milk replacer fed each day may be increased. Always feed a minimum of 10% of calf bodyweight per day. Calves may be fed up to 15% of bodyweight as liquid milk replacer.

    Based on the required mixing rate, mix 150g or 250g of Ravensdown
    CMR with water to make up 1L.
    • Add the required amount of powder to half the volume of hot water
    (45°C - 55°C) and mix vigorously. Top up with cold water to the
    required final volume and temperature.
    • Milk replacer should be fed at 38°C – 42°C for optimum results.

  • VAT MILK VS CMR

     

    Whey based CMR

    Milk from the vat

    Encourages
    early hard feed
    intake

    Non-curding milk replacers encourage early feed intake, rumen development and eases the transition at weaning

    Hard feed intake is slower and
    rumen development starts later in
    milk fed calves

    Consistency

    Consistent nutrient profile ensures calves receive the correct amount of energy and protein to support early growth and development

    Fat and protein content can vary
    from day to day.

    Microbial
    quality

    Quality control at point of manufacture
    ensures low risk of microbiological
    contamination

    Somatic cell count and bacterial
    loading can vary from day to day.

    Risk of disease
    transmission

    Pasteurisation, quality control and MPI
    regulatory controls remove the risk of
    disease transmission.

    Without heat treatment there is a
    risk of vertical transmission of
    diseases within or between herds

    Cost effective

    International pricing and demand means
    whey based CMR is cost-effective.

  • WHAT YOU NEED TO KNOW

    Ensure calves receive 4 – 6L of high quality colostrum within the first 12 hours after birth.

    • Feed colostrum from day 0 – 4, at a minimum of 10% of calf body weight.
    • Introduce change slowly when altering feeding patterns.
    • Provide ad lib access to a high quality grain based calf starter feed from day five, with small amounts of good quality fibre, to help support rumen development.
    • Ensure a supply of clean, fresh water is available at all times.
    • Calves can be weaned when they consistently consume 1kg of calf meal each day over a three day period.
  • STORAGE

    Clean, dry, 10-20 °C, 60% relative humidity, away from strongly odorous materials.
