Abstract: The invention relates to a nutritional composition comprising carbohydrates, protein and a fat composition, wherein: (a) the nutritional composition has a total calcium content on dry matter of at least 3.5 g/kg; (b) the protein comprises casein; (c) the nutritional composition has a content of protein-bound calcium of 7.5 mmoles or less per 10 grams of casein; and (d) the ratio NPN to TN is 0.7 or less, with:—NPN meaning non-protein nitrogen in the nutritional composition in grams per 100 grams of nutritional composition (g/100 g); and—TN meaning total nitrogen (TN) in the nutritional composition in g/100 g.

Abstract: The present invention relates to bovine milk fat comprising, based on total fatty acid content, 8.9-29.0 wt % linoleic acid (C18:2 cis, 9,12), 0.9-2.4 wt % alpha-linolenic acid (C18:3 cis 9,12,15), and 3-5 wt % butyric acid (C4:0). The present invention further relates to a bovine milk comprising said milk fat and to a method for producing said milk by feeding a lactating bovine mammal with a rumen-protected linoleic acid source and a rumen-protected alpha-linolenic acid source, followed by milking the lactating bovine animal.
