	abstract = {Plasma carotenoid (PC) concentrations were measured at 2-5 month  intervals in 20 Hereford x Jersey (HJ) and 20 Hereford x Friesian (HF) once  bred heifers from 10-35 months-of-age. Half of the heifers were slaughtered  at 31 months-of-age and the rest at 35 months-of-age. The colour of the  subcutaneous and intermuscular fat was measured using a chromameter and  c* values were calculated. Subcutaneous and intermuscular fats in HJ  heifers were yellower (i.e. they had higher c* values) than in HF heifers.  Regression equations that included breed, date of slaughter and PC  concentrations at 10-12 months-of-age, accounted for 56\% of the variation  in c* values for subcutaneous fat and 40\% of the variation in c* values for  intermuscular fat (P<0.001). },
