Could you re­peat that?

Dairy News Australia - - OPINION -

Would you like a guide to trans­late what your cows mean when they bel­low? Or do you reckon you’ve got the gist? PhD can­di­date at the Univer­sity of Syd­ney, Alexan­dra Green, is study­ing cat­tle bioa­cous­tics, or as she says, “cow-moo-nica­tion”. Alexan­dra is record­ing the vo­cal­i­sa­tions of dairy heifers and try­ing to work out what they are say­ing in re­sponse to dif­fer­ent farm­ing con­texts. Es­sen­tially, early work shows cows will be­come more vo­cal when they are stressed or ex­cited, but there is much more to learn. We’d be sur­prised if the study turns up any­thing that Aus­tralian dairy farm­ers don’t al­ready know but it prom­ises to be an in­ter­est­ing jour­ney.
