A NEW GRAZING SYSTEM FOR BEEF CATTLE—THE TWO FIELD SYSTEM

A new simplified grazing management system has been devized for spring- or antumn-born calves scbednled for beef production at 18 months of age on a grass/cereal system. The new system which can be conveniently described as the two-field system obviates the need for paddock fencing and paddock water installations, is simple to operate and is giving results in terms of liveweight gain performance and stocking rates per acre which are comparable with those from paddock systems. The new system employs the old practice of set-stocking. Two fields are used, however, and these are alternately set-stocked and cut for silage, or vice-versa. It has been found that by using N fertilizer to the same extent as in intensive paddock systems, i.e. around 250–350 units N/ac, it has been possible to achieve similar stocking rates/ac and performance has been unimpaired. No bealth upsets have occurred as a result of applying fertilizers on fields in the presence of grazing cattle over a period of four years at two centres, Jealott's Hill and The Leaths, in trials involving hundreds of beef cattle and dairy cows. This new system of grazing management for beef cattle is now well proven and can now be recommended to farmers as an alternative to paddock grazing.
