Help and AdviceCalf rearing hints, research and best practice
When a delegation from Ireland’s Bonanza Calf Nutrition visited New Zealand to learn more about dairy and calf rearing there, one was thing immediately clear.
Choosing a rearing system for orphan and multiple lambs that matches labour availability and numbers in combination with providing the right nutrition is key to success.
Calf milk replacers (CMRs) are typically formulated from a range of lower-value milk products and may have reduced curding
ability when casein proteins are absent or denatured. Whilst there are industry claims that vealer calves in Europe can be reared on
such CMRs, there is no NZ data to substantiate these claims.
Calf-rearing systems on dairy farms and specialist calf rearing units: results of a New Zealand survey
Calf-rearing practices were surveyed on 297 dairy farms with an average of 82 heifer and 24 bull calves reared. Only 21% of
the properties fed colostrum immediately on arrival at the dairy shed, and 30% did not feed their calves for at least 8 hours after

Calves fed hay in conjunction with a high-quality milk replacer have achieved higher weight gains than those offered straw.
Last year Northern Irish farmers Chris Catherwood and Jason Rankin won the All Ireland calf rearer of the year award and received a computerised machine as a prize. For the last two years the calves on the Cannon farm had been reared using teated feeders and were fed a skim and buttermilk based milk replacer once a day (OAD).

Transition milk is the milk cows produce after colostrum and before what we consider ‘whole milk’.
Good colostrum management is vital to ensure the health and well-being of your lambs Colostrum contains high levels of antibodies, and has much greater total solids content than whole milk.
Although it may not seem so, the perinatal period is the most risky period in the life of a calf. Getting a live calf on the ground is crucial in all our books, however ensuring the calf doesn’t contract disease when it gets there is another imperative battle to be fought.
In our guide to milk feeding lambs we explore the best milk feeding option for your system, advantages and disadvantages of bottle feeding and more.
Colostrum management for newborn calves remains a problem on many farms. The modern dairy cow doesn’t share the same level of maternal instinct as her predecessor. She may produce a greater volume of colostrum but it is more dilute.
Possible ways to advance survival of the newborn lamb is to maximise lamb vigour, encourage maternal bonding, enhance colostrum production, select on behaviour traits, and improved feed management during late pregnancy.
