摘      要：This experiment was conducted to investigate growth performance,carcass traits and meat quality of finishing pigs with dietary β-glucan supplementation.A total of 96 healthy pigs(Duroc x Landrace x Yorkshire;initial average BW=25 kg) were randomly allocated into 4 dietary treatments with 6 replicates per treatment and 4 pigs per *** control group was fed a basal diet,and the experimental diets were supplemented with 50,100 and 200 mg/kg Agrobacterium ***09β-glucan,*** experiment lasted 103 *** basal diet supplemented with 100 mg/kg β-glucan significantly increased average daily gain and feed conversion ratio,probably due to the improved digestibility of dry matter,gross energy and crude protein(P 0.05).Beta-glucan supplementation from100 to 200 mg/kg of diet significantly increased carcass length(P 0.05).The basal diet supplemented with 100 mg/kg β-glucan supplementation also significantly(P 0.05) increased muscle pH,reduced drip losses and increased a~**** basal diet supplemented with 100 mg/kg β-glucan increased the content of intramuscular fat and changed the proportion of saturated fatty acid and unsaturated fatty acid,thereby improved the flavor of *** conclusion,the basal diet supplemented with 100 mg/kg Agrobacterium ***09 β-glucan improves growth performance,nutrient digestibility,carcass length,and pork quality of finishing pigs.
