Heifer Weighing and Animal Health Program

As heifers are grazing further and further from home adequate monitoring of weights and animal health treatments is becoming increasingly difficult to fit into busy farm schedules. As seen in recent studies;18% of heifers monitored were more than 20% behind target at 15 months of age, in a recent LIC study.

             ·         73% of the population were more than 5% below target at 22 months and by that age, on average, all heifers were

                       11% below target  (McNaughton and Lopdell).

             ·         Close to 18% of these heifers did not re-calve as 3yr olds.

             ·         At a $4 payout, each additional kg of LW at 22 months between 80-90% of mature liveweight will return around $1 in

                        the first lactation. (Dairy NZ)

             ·         Achieving the 15 month liveweight target will help minimise the incidence of non-cycling heifers at mating. (Dairy NZ)


In light of this, Selwyn Rakaia Vet Services Ltd now offers heifer weighing as a standalone service or in conjunction with an animal health program. 


The program is customised to each group of heifers, and each group is monitored on a monthly basis. 

Some key points of the program are:

             ·         An 18 month fully managed program (Shorter term programs available if


             ·         Weighing and reporting against “MINDA weights” or agreed target weights

             ·         Supply of all animal health products and co-ordinating of application including

                       the provision of qualified applicators where required.
