15 Friesian and 9 Ayrshire bull calves were fed 1 of the following 3 diets ad lib. after each had received 7 kg whole colostrum: (i) fresh liquid skim-milk (SM) containing 0.1% milk fat; (ii) reconstituted spray-dried SM containing 2.8% margarine fat; and (iii) as (ii) for 14 days from birth, followed by (i). (Fat content of DM in (i) and (ii) was 1.3 and 20.5% respectively). Tabulated data include values for apparent digestibility of lactose, DM, protein and fat from diets (i)-(iii). Apparent digestibility of lactose and apparent absorption of ash and Ca were greater with (ii) than with (i). Friesian calves were less susceptible to the adverse effects of (i) (having a lower incidence of diarrhoea) compared with the Ayrshires.
