The secretion of β-carotene in milk was related to intake, but at a very low mean efficiency of 0.07%. The difference in vitamin A contents among the two feeding variants was of low significance. Havemose et al. (2006) calculated the transfer of β-carotene to milk at 6.8% and 1.8%–2.2% from grass–clover silage and hay, respectively.
