UNASSIGNED: The aim of the study was to determine the effects of two different fat sources ( @entity1460 oil (SO) and beef tallow (BT)) in dry extruded @entity235 diets on the intake of food and metabolizable energy (ME), on faecal characteristics and apparent total tract digestibility (ATTD) of nutrients and energy. Ten adult @entity235 of different breeds were used in a Latin square design. Five experimental diets were designed from a basal diet. A Control diet was coated with 1% SO and four other diets were obtained by coating the basal diet with 6.5% and 13% of SO or BT. The Control, 6.5% and 13% coated diets contained approximately 8.5%, 15% and 20% fat, respectively. The @entity235 had similar @entity62 ( @entity62 ) intakes and, consequently, higher ME intakes with an increased fat content for both sources (p  <  0.05). Fat digestibility was highest for Diet SO13% (p  <  0.05). The ATTD of @entity62 and organic matter was highest (p  <  0.05) for Diets SO13% and BT13%. Fat coating improved the faecal score, especially for Diet BT13%. The dietary ratios of protein:fat: @entity1735 [% of ME] were close to AAFCO's estimates. For SO a higher ATTD (99.1%) and ME content (38.88  MJ/kg) was estimated than for BT (ATTD 92.9% and 36.37 MJ ME/kg). Both SO and BT can comprise up to 13% of the diet. However, SO was more susceptible to leaking from the kibbles with the coating method applied.
