The effects of three stocking rates on fat‐lamb production were examined. These stocking rates were imposed upon four grazing systems. The grazing managements had no significant 1 effects upon the rate of liveweight gain or the total liveweight of lamb produced per acre, nor were the ewes’ liveweights significantly affected. Reasons are suggested. The lambs’ rate of liveweight gain was related negatively and the total liveweight of lamb produced per acre was related positively to stocking rate. The ewes’ liveweights were similarly affected, there being the highest losses of liveweight under the high stocking rate. In all cases significant differences existed between the stocking rates and there was a significant linear relationship between them. It is concluded that high stocking rates are essential to obtain the maximum fat‐lamb production on a ‘per acre’ basis.
