Abstract：This experiment aimed to investigate the effects of the Camellia oleifera-alfalfa farming model on the growth performance and meat quality of Anyi Gray chickens.Twelve plots of equal size(300 m² each)were randomly selected in a 3-year-old Camellia oleifera forest and divided into two groups:A clean tillage grazing group and a Camellia oleifera-alfalfa grassland grazing group.Each group had three replicates,with one rotational grazing plot per replicate.The stocking density was 115 birds per 667 m²,and rotational grazing occurred every 30 days.The Camellia oleifera-alfalfa group received 80%of the concentrate feed provided to the clean tillage group daily.The trial lasted 90 days.Results showed that compared to the clean tillage group,the Camellia oleifera-alfalfa group exhibited significant increases in breast depth,live weight,slaughter weight,and weights of the spleen and duodenum(P<0.05).The pH of breast muscle significantly decreased(P<0.05),while leg muscle pH significantly increased(P<0.05).Crude fat content in both breast and leg muscles decreased significantly(P<0.05),whereas crude protein content in leg muscle increased(P<0.05).Breast muscle showed a significant reduction in saturated fatty acid decanoic acid(P<0.05),and leg muscle displayed significantly lower copper and calcium levels(P<0.05)but higher selenium content(P<0.05).The study demonstrates that the Camellia oleifera-alfalfa farming model enhances slaughter performance and meat quality in Anyi Gray chickens,providing valuable guidance for forest-based broiler farming.
