摘要: This study investigated the effects of partially replacing corn with elephant grass dry matter (air drass) on growth performance, serum parameters, carcass traits, and nutrient digestibility in geese. A total of 360 one -day -old Hortobagyi geese were randomly divided into three groups: control (basic diet), 12 % elephant grass, and 24 % elephant grass. The geese were raised for 70 days. The results showed that compared to the control, 12 % elephant grass had no adverse effects on final body weight, feed/gain ratio, mortality, serum liver and kidney function markers. However, 24 % elephant grass significantly reduced the final body weight ( P < 0.001) and feed/ gain ratio ( P = 0.026) compared to the control group. Both experiment groups had decreased serum aspartate aminotransferase ( P < 0.001), alanine aminotransferase ( P < 0.001), alkaline phosphatase ( P < 0.001), triglycerides ( P < 0.001), and total cholesterol ( P < 0.001). The addition of 12 % and 24 % elephant grass reduced abdominal fat ( P = 0.002), but it had no significant effect on slaughter rate, half -bore rate, full -bore rate, breast muscle rate and leg muscle rate. For nutrient digestibility, 12 % elephant grass improved neutral detergent fiber digestibility compared to the control group ( P = 0.026). The 24 % grass group had reduced Ca absorption ( P = 0.020). Overall, the findings suggest that partially replacing corn with 12 % elephant grass in goose diet can maintain growth performance and carcass traits.It also has no negative effect on nutrient digestibility while improving serum parameters.
