  • Not only will the on-going dry period be knocking cow performance, but it will be having an effect on the young stock performance as well.  A lot of replacement heifers move to off-farm grazing in over the summer period and with that the opportunity to remain “hands on’ with their management is correspondingly diminished.

    Successful contract heifer growing arrangements are dependent upon effective communication and making sure that the relationship works well for each party.  Before entering into a contract grazing relationship, it is important that the expectations of both parties are well understood and there is an opportunity for regular communication on any issues that might arise.

    As well as protecting the interests of both parties, the process of going through the contract helps to identify and agree on the issues that are important to each party.  The responsibilities of all parties (including any other service providers) needs to be agreed on at the commencement of the grazing.  This does not replace the use of a grazing contract and may not be needed if a contract is used that clearly documents who is responsible for what.

    You’ll need to agree on what adverse events (droughts or floods are likely to be the most common) are that could put the desired outcome in jeopardy.  A plan needs to be created to minimise the impact the event may have on achieving liveweight targets.

    A lot of the communication will be focussing on the liveweight progress of the heifers in relation to their targets.  A simple summary that can be filled in during a phone conversation or farm visit as a monthly record of events can be useful. 

    If expectations are not being meet by either party then action needs to be taken to bring things back into line.  It can be hard to know when to start having these conversations, but it is important to address any problems before they escalate to a point where heifers are adversely affected or the relationship breaks down completely.

    The replacement stock are generally the highest genetic merit animals you own and are the foundation of the future production of your herd and farm business.  Putting some effective measures in place not only makes sense, it’s a good business practice.  For more information go to www.dairynz.co.nz/animal/heifers/contract-grazing/
