发酵棕榈粕替代部分玉米和豆粕对肉鸡生产性能、血液生化指标及肉品质的影响OA

[Objectives]The effects of adding different proportions of fermented palm meal(FPKC)as a substitute for maize and soybean meal in the diet on the growth of broiler chickens were studied to provide ref-erence for the rational application of fermented palm meal in the production of farming broilers.[Methods]360 healthy 1-day-old male Cobb 500 broiler chicks with uniform body weight(43.2±2.16 g)were randomly di-vided into 3 treatment groups including the control group,the experimental group I with 5%FPKC replace-ment,and the experimental group Ⅱ with 10%FPKC replacement group,with 8 replicates in each group and 15 chicks per replicate.The experimental period was 42 days.The growth performance,biochemical indexes in blood,meat quality and organ-related parameters of broilers were measured at different stages of growth.[Re-sults]Groups Ⅰ and Ⅱ had no negative effects on growth performance and biochemical indexes in plasma of broilers during the whole period(P＞0.05)compared with the control group.The feed-to-gain ratio of broilers aged 1-21 days in Group Ⅱ was significantly higher than that in Group Ⅰ by 8.89%(P＜0.05).Groups Ⅰ andⅡ significantly improved the color and tenderness of meat(P＜0.05),and the development of liver and cecum(P＜0.05),with no negative effects on the development of organs in broilers(P＞0.05).[Conclusions]Replacing 5%and 10%of the total amount of maize and soybean meal in the diet with FPKC had no negative effect on the growth performance,biochemical indexes in blood and meat quality of broilers.It is indicated that the re-placement of FPKC for maize and soybean meal in the diet can save costs of feed without affecting the growth performance of broilers.It is recommended to use a 5%FPKC replacement at the early stage of growth and a 5%to 10%FPKC replacement at the later stage of growth of broilers.
