UNASSIGNED: One-day-old female @entity233 were randomly assigned to five dietary treatments and were fed for 15  weeks diets containing 5% of cellulose (control, C) or 5% of dried fruit pomaces (apple, black currant, strawberry, seedless strawberry; AP, BCP, SP, SSP respectively). In weeks 11-15 of feeding, all diets were supplemented with 2.5% of linseed oil. The crude fibre content of fruit pomaces ranged from 56.5% in AP to 62.9% in SP. In comparison with AP, berry fruit pomaces (BCP, SP and SSP) were characterised by a higher content of neutral detergent fibre - NDF (41.2% vs. 52.7-59.3%) and lignin (13.24% vs. 21.80-25.56%). A monomer analysis revealed that cellulose was the main non-starch polysaccharide (NSP) in fruit pomaces, whereas their pectin content was low. @entity3978 content was determined at below 6  g/kg in AP, at approximately 12  g/kg in BCP and SP, and at 32.8  g/kg in SSP. There were no significant differences (p  >  0.05) in final body weight of birds. After 15  weeks of feeding fruit pomaces to @entity233 , the relative weight of the small intestine with digesta was higher in group AP, and lower in group SSP, as compared to controls. Dietary fruit pomaces decreased the @entity62 ( @entity62 ) concentration and lowered the pH of the small intestinal digesta, except the AP and SSP treatments respectively. In the caeca, significantly reduced concentrations of @entity3265 or putrefactive short-chain @entity1718 (SCFA) upon dietary fruit pomaces were observed. Fruit pomaces did not influence the concentrations or the total pool of short-chain @entity1718 , but led to a significant increase in butyric proportion in the SCFA profile at the expense @entity4919 .
