The present invention relates to use of a fat-enriched, solid feed combination composition comprising at least a first solid feed composition which is in the form of a pellet comprising one or more fermentable feed ingredients, and a second solid feed composition, wherein the first composition comprises between 20 and 90 wt.% of fat and wherein the second composition comprises one or more fermentable feed ingredients, and wherein the total fat content of the solid feed combination is in the range of 5-20 wt.%, for feeding a ruminant calf. The solid feed combination composition of the invention is particularly suitable for ingestion by a ruminant calf during and/or after the weaning period and can be advantageously used in methods carried out during and/or after the weaning period for: 1 ) for decreasing weaning stress in a ruminant calf, 2) for preventing a decrease in body weight and/or somatic growth of a ruminant calf, 3) for increasing solid feed intake of a ruminant calf, 4) for maturing the rumen of a ruminant calf, and 5) for improving the gut health and/or the gastrointestinal function of a ruminant calf.
