Calf Milk Replacer

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.

  Twice-A-Day

  Calf age in days	Liquid per feed	Feeds per day	Mixing rate/L	Milk replacer intake per day
  Days 5 - 14	2.0L	2	150g/L	600g
  Days 15 - 28	2.5L	2	150g/L	750g
  Days 29 - 42	3.0L	2	150g/L	900g
  Days 43 - 56	2.5L	2	150g/L	750g
  Days 57+	2.5L	1	150g/L	375g

  Once-A-Day

  Calf age in days	Liquid per feed	Feeds per day	Mixing rate/L	Milk replacer intake per day
  Days 5 - 14	2.0L	2	150g/L	600g
  Days 15 - 28	3.0L	1	250g/L	750g
  Days 29 - 42	3.5L	1	250g/L	875g
  Days 43 - 56	3.0L	1	250g/L	750g
  Days 57+	1.5L	1	250g/L	375g

  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.	Vat milk used to feed calves could be sold

• 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.
