Dietary Jerusalem artichoke polysaccharide supplementation alters the growth performance, ruminal microbes and metabolites, muscle fatty acid and amino acid profiles in fattening lambs.

ABSTRACT: The Jerusalem artichoke polysaccharide (JAP) acts as a prebiotic in ruminants. This study investigated the effects of dietary JAP supplementation on growth performance, meat traits, rumen microbes, and metabolome of fattening lambs. A total of 72 healthy crossbred ram lambs (Small Tail Han sheep × Black Bone sheep), aged three months (body weight = 26.21 ± 2.14 kg), were randomly assigned to 12 pens. The pens were evenly divided into two groups: one receiving a basal diet (the CON group) and the other receiving a basal diet supplemented with 0.5% JAP (the JAP group). Compared to the CON group, the JAP group exhibited higher final body weight (P = 0.028), average daily gain (ADG) (P = 0.013), and carcass weight (P = 0.004), as well as a significantly lower feed conversion ratio (FCR) (P = 0
