At the b eginning of the

depression of the early thirt i e s , th e Federat ion and the C entral Executive real ised that sp ecial effort s would be ne cessary to prevent herd reoordine

go ing

into decl ine at a t ime when its expansion could b e most b eneficial. The b est methods f'armers could use

to offs et

low dairy produce prices were to reduce their costs of product ion and increas e their output s,

It

was thought that herd rocordine, by idcnt ifyine lovJ producers and serving

as a guid e t o b ot t er f'nrm manugement could b e an important factor

in

at�uining the s e ends. Sp ecial steps were therefore

taken to induce

more farmers to record. They included:

1. Reducing the cost of' recording to the �armer. For this
