【摘要】：本试验旨在研究饲粮中添加有机复合酸化剂(富乳酸)对肉鸡生产性能和消化功能的影响,为富乳酸的应用推广提供理论依据。试验选用600只1日龄AA肉公鸡,分为2个组,每组6个重复,每个重复50只。对照组饲喂基础饲粮,试验组饲喂在基础饲粮中添加0.1%富乳酸的试验饲粮。试验期42天。结果显示,富乳酸显著提高肉鸡22~42及1~42日龄平均日增重(P0.05),降低肉鸡22~42及1~42日龄料肉比(P0.05);显著提高肌胃相对重量(P0.05)及十二指肠、空肠绒毛高度(P0.05)和绒毛高度/隐窝深度(VH/CD)比值(P0.05),提高回肠VH/CD比值(P0.05);显著提高肌胃、腺胃中总酶、酶活性及激活度(P0.05)和十二指肠、空肠中胰蛋白酶、淀粉酶和脂肪酶活性(P0.05)。由此可见,饲粮中添加富乳酸促进消化系统的发育,提高消化酶活性及饲料转化率,进而加快肉鸡的生长。
[Abstract]:The purpose of this experiment was to study the effect of adding organic compound acidifier (lactic acid rich) in diet on the performance and digestibility of broilers, and to provide theoretical basis for the application and popularization of lactic acid. 600 1-day-old AA broiler cocks were divided into 2 groups, 6 replicates in each group and 50 in each group. The control group was fed with basic diet and the experimental group was fed with 0.1% lactic acid enriched diet. The trial period was 42 days. The results showed that lactic acid enrichment significantly increased the average daily gain (P 0.05), decreased the feed / meat ratio (P 0.05), significantly increased the relative weight of muscle stomach (P 0.05) and duodenum (P 0.05), decreased the feed / meat ratio (P 0.05), and significantly increased the relative weight of muscle stomach (P 0.05) and duodenum (P 0.05). Jejunum villus height (P0.05) and villi height / crypt depth (VH/CD) ratio (P0.05) increased the ratio of VH/CD in ileum (P0.05), and significantly increased the activities of total enzyme, enzyme activity and activation (P0.05) in muscle stomach and glandular stomach, and the activities of trypsin, amylase and lipase in duodenum and jejunum (P0.05). It can be seen that lactic acid rich in diet can promote the development of digestive system, increase the activity of digestive enzyme and feed conversion rate, and then accelerate the growth of broilers.
