| 摘要: |
| 选用1日龄银香肉仔鸡1000只,随机分成2组,每组500只,设2个重复,分别在基础日粮中添加0和0.1%的益生素,研究益生素对0~7周龄银香雏鸡生产性能和健康状况的影响。共饲养7周,每周统计耗料量、腹泻率、抽样测体重,并对49日龄雏鸡取样测定肠道微生物浓度。结果表明,试验组各周平均体重分别比对照组增加3.40%,3.52%,10.04%,9.08%,8.53%,11.65%,其中第3周、第4周、第5周和第6周差异极显著(P<0.01),第1周和第2周差异不显著(P>0.05)。从各周的增重率来看,第1周、第3周和第6周分别比对照组高19.31%、17.15%和21.56%(P<0.01);第4周比对照组高7.08%(P<0.05);第2周和第5周也高于对照组(P>0.05)。全期益生素组平均增重比对照组高12.81%(P<0.01)。试验组腹泻死亡总数及腹泻死亡率均低于对照组,且差异显著(P<0.05)。试验组空肠和盲肠的大肠杆菌浓度分别比对照组低26.16%和27.90%(P<0.05),沙门氏菌在两组中都很少,试验组空盲肠的乳酸菌浓度分别比对照组高20.96%和13.52%(P<0.05)。 |

| Abstract: |
| The effects of probiotics on performance and health of Yinxiang chickens were studied in the Grststage.1000 1day-old chickens were allotted randomly to two treatments, 500 chickens of each, with two replicates.The treatment encompassed of 0.1% probiotics in the basic diet and 0% probiotics in the diet as control.The probiotics used in the experiment consists of Lactobacillus and 3Bacilluses.The treated diets were fed for 7 weeks.Feed intake, average body weight, diarrhea rate were recorded weekly.At 49-day age, intestinal floras content was measured.The results showed that the body weight gain of birds fed with 0.1% probiotics diet was 10.04%, 9.08%, 8.53% and 11.65% higher than that of the controls (P<0.01) in the third, fourth, fifth and sixth week, respectively.No significant difference was observed in other weeks (P>0.05).Compared with the control group, the feed conversion rate of chickens fed with 0.1% probiotics diet increased by 19.31%, 17.15%, 7.08% and 21.56% in the first week (P<0.01), the third week (P<0.01), the fifth week (P<0.05), and the sixth week (P<0.01), respectively.There were no significant difference in other weeks (P>0.05).During the age from 0 to 6 weeks, the average body weight gain of birds gived 0.1% probiotics diet revealed 12.81% higher than that of the control ones (P<0.01).The contents of Eschericltia coli in jejunum and caecum decreased by 26.16% and 27.90% (P<0.05) in the probiotics group than those of the control one.The content of Lactic acidin entric increased 20.96% and 13.52% in the probiotics group (P<0.05).Both the diarrbea rate and the mortality of the probiotics group declined when compared with those of the control (P<0.05). |
