GILT REARING FOR LIFE-LONG PERFORMANCE:
W.H. Close and P. Toplis

Abstract
The young gilt is the future of any pig production enterprise and, like any other business investment, must be treated with great care and attention. She must be fed and managed properly to help her achieve her full breeding potential of five to six litters per lifetime. It is well established that the premature culling of breeding females and lifetime productivity impact heavily on the cost of production. Indeed, the way producers rear and manage their gilts is of utmost importance to sow herd productivity. This paper looks at some of the latest thinking on the relative importance of lean and backfat thickness at the commencement of breeding. Targets are suggested for body weight and age at mating and nutrient requirements to achieve these are given. Some feeding strategies and management requirements are outlined.
