摘要
[目的]研究双益素对蛋鸡盲肠微生态及蛋品质的影响。[方法]选择42周龄同一批次、健康的海兰褐商品蛋鸡3780只，随机分成试验组和对照组，对照组饲喂基础日粮，试验组在基础日粮中添加0．25‰双益素，研究双益素对蛋鸡盲肠微生态指标和蛋品质的影响。[结果]与对照组相比，试验组盲肠乳酸杆菌含量提高0．063×108 CFU／g，差异显著（P＜0．05），大肠杆菌含量降低0．184×108 CFU／g，差异显著（P＜0．05）；试验组鸡蛋蛋壳厚度和蛋壳强度分别提高0．03 mm和3．31 N，差异显著（P＜0．05）；试验组鸡蛋中蛋白质、钙和磷含量比对照组分别提高1．55％、0．012％和0．026％，差异显著（P＜0．05）。[结论]双益素能有效调控肠道微生态内环境，改善蛋品质，提高鸡蛋营养价值。
Abstract
Objective] The aim was to investigate the effect of Double Bioimmune on cecal microecology and egg equality of layers.[Meth-od] A total of 3 780 42-week-old healthy HY-Line Brown commercial laying hens were randomly divided into test group and control group.The control group were fed basal diet and the test group were fed basal diet supplemented with 0.25‰ Double Bioimmune.Effects of Double Bio-immune on cecal microecology and egg equality of layers were studied.[ Result] Compared with control group, the number of Bacillus acidi lactici in cecal of the test group were increased 0.063 ×108 CFU/g, significant difference (P<0.05), the number of E.coli were decreased 0.184 ×108 CFU/g, significant difference (P<0.05); eggshell thickness and eggshell strength of the test group were increased respectively by 0.03 mm and 3.31N (P <0.05), while protein, calcium and phosphorus content of egg in test group were significantly increased by 1.55%, 0.012%, 0.026%(P<0.05), remarkably.[Conclusion] Double Bioimmune could effectively regulate the intestinal micro ecolog-ical environment and improve egg quality, increase the nutritional value of eggs effectively.
