Improving hogget performance through efficient management of the spring surplus

Abstract

This paper examines how the spring management options of making silage or planting brassicas can change hogget performance. Research by Gore Research Station staff compared winter hogget growth on various winter forages including brassicas, Italian ryegrass, perennial pasture and silage from several pasture types over 5 years. Liveweight gains varied from 0 to 160 g/day for silage made from various pasture options. Specific brassicas or brassica plus Italian ryegrass combinations provided average gains of up to 146 g/day. The yields of forage turnips for summer and autumn use were also compared. An initial harvest of 90 days with two subsequent cuts of 30- day intervals maximised yields from the treatments examined. The combining of these spring forage management options is discussed and used to outline options which will help farmers to maximise hogget performance.
