【摘要】：本试验旨在研究饲粮中添加绿狐尾藻粉对芦花鸡生长性能、屠宰性能、血清生化指标及肌肉氨基酸含量的影响。选取30日龄健康芦花鸡240只,随机分为3组,每组4个重复,每个重复20只。对照组饲喂基础饲粮,试验组分别在基础日粮中添加7%和12%绿狐尾藻粉,试验期为42 d。结果表明:与对照组相比,在30~44日龄和59~72日龄,试验组芦花鸡的生长性能未发生明显改变(P0.05),但在45~58日龄,7%绿狐尾藻粉组芦花鸡的平均日采食量和平均日增重显著提高(P0.05),且有提高全期芦花鸡平均日增重的趋势(P=0.086);12%绿狐尾藻粉组芦花鸡的血清白蛋白含量显著降低(P0.05),7%绿狐尾藻粉组芦花鸡的血清谷丙转氨酶活性显著降低(P0.05);7%绿狐尾藻粉组芦花鸡胸肌中天冬氨酸与鲜味氨基酸含量分别提高了6.81%和3.83%(P0.05),腿肌中丙氨酸、精氨酸与鲜味氨基酸含量分别提高了14.30%、20.92%和10.00%(P0.05),12%绿狐尾藻粉组芦花鸡腿肌中赖氨酸含量显著降低(P0.05)。综上,饲粮中添加绿狐尾藻粉对30~72日龄芦花鸡的生长性能影响不明显,但添加7%绿狐尾藻粉可以改善芦花鸡的血清生化指标,并可增加肌肉鲜味氨基酸含量。
[Abstract]:The purpose of this experiment was to study the effects of algae-green fox powder on growth performance, slaughter performance, serum biochemical index and muscle amino acid content of Luhua chicken. 240 healthy 30-day-old Luhua chickens were randomly divided into 3 groups with 4 replicates in each group and 20 repeats in each group. The control group was fed with basic diet and the experimental group was fed with 7% and 12% green fox tail algae powder in the basal diet for 42 days. The results showed that, compared with the control group, the age of 30 days and 59 days was 44 days and 59 days, 72 days respectively. The growth performance of the experimental group did not change significantly (P0.05), but the average daily feed intake and average daily gain increased significantly (P0.05) at 45 ~ 58 days old (P0.086), and the average daily gain increased by 12% (P0. 086) in the experiment group (P0. 086). The serum albumin content of algae-green fox powder group decreased significantly (P0.05) the serum glutamate-pyruvic transaminase activity of 7% green fox tail algal powder group was significantly decreased (P0.05) aspartic acid and fresh amino acid content in breast muscle of 7% green foxtail alga powder group were significantly decreased (P0.05). The contents of alanine in leg muscle were increased by 6.81% and 3.83% (P0.05), respectively. The contents of arginine and fresh amino acid increased 14.30% and 10.00% (P0.05) respectively. In conclusion, the growth performance of 30 ~ 72 days old Luhua chickens was not affected obviously by adding green fox tail algae powder in diet, but 7% green fox tail algae powder could improve the serum biochemical index and increase the content of fresh amino acids in muscle.
