【摘要】：研究旨在观察核苷酸-甜菜碱、核苷酸-大豆异黄酮、甜菜碱-大豆异黄酮三种添加剂组合对苏邮2号麻鸭生长性能、屠宰性能及肉品质的影响。选用体重1日龄的苏邮2号麻鸭160只,按试验要求随机分为4组,每组4个重复,每个重复10只,公、母各半,分别饲喂含呈味核苷酸0.3%、甜菜碱0.1%和大豆异黄酮0.003%三种添加剂组合的日粮,饲养试验时间为70 d。结果表明,核苷酸-大豆异黄酮添加组麻鸭的70日龄平均体重、平均日增重显著高于对照组(P0.05);核苷酸-大豆异黄酮组合添加组胸肌系水率显著高于对照组(P0.05);3种添加剂组合对肉鸭肌肉中的肌苷酸含量都有显著提高(P0.05),肌苷酸含量分别比对照组提高12.12%、11.52%和9.70%,3种添加剂组合对麻鸭肌肉中的氨基酸总量及必需氨基酸含量、鲜味氨基酸含量等都有所提高。该结果表明,甜菜碱-大豆异黄酮复合添加剂和核苷酸-大豆异黄酮复合添加剂对麻鸭生产性能有一定的促进作用,并可提高肌肉中风味物质的含量。
[Abstract]:The aim of this study was to observe the growth performance of Suyou 2 Ma Duck with three additives: nucleotide-betaine, nucleotide-soybean isoflavone, betaine and soybean isoflavone. The effects of slaughter performance and meat quality on the performance of slaughtering and meat quality. 160 suyou 2 ducks weighing 1 day were randomly divided into 4 groups according to the requirements of the experiment, 4 replicates in each group, 10 in each group, half in male and half in female. The diets containing flavor nucleotides 0.3%, betaine 0.1% and soybean isoflavone 0.003% were fed with diets for 70 days. The results showed that the average body weight of the ducks fed with nucleotide-soybean isoflavones was 70 days old. The average daily gain was significantly higher than that of the control group (P 0.05A), and the water rate of pectoralis in the nucleotide-soybean isoflavone group was significantly higher than that in the control group (P 0.05). The inosine acid content and inosine acid content in the muscle of the meat duck were significantly increased by the combination of three additives. Compared with the control group, the contents of amino acids and essential amino acids in muscle were increased by 12.12% 11.52% and 9.70%, respectively. The results showed that betaine-soybean isoflavone compound additive and nucleotide-soybean isoflavone compound additive could promote the production performance of Ma duck. It can increase the content of flavor substance in muscle.
