If the heifer looks nearly finished, it is too fat. We all want 1st-calf heifers in very good condition at calving but not too fat. We would be better restricting the gain the last month cutting them back. If fat globules are visible and the chest (brisket) is fatty wide looking we may have put too much fat. Too much fat during development (rates of gain above 1.5 lb/day) in British breeds tend to overfatten the udder which goes against alveolar development. Fatty udders at early stages do no develop the gandular function properly and will produce less milk in the future. Excesive energy in the las two months of pregnancy highly correlates with calf size which can resultin calving problems. Cut back on feed the last months. You also need t trigger endogenous calcium movilization (from bone tissue) for calcium homeostasis during early lactation. Cutting back in total feed prior to calving helps.
