【摘要】：巴尔麦氏是一种具有高效功能性、碱性离子化、免疫增强剂的生物饲料添加剂,它含有Si、Ge、Ag、Au、Ti、Zn2+、Fe2+等,增强机体免疫力和生物细胞组织再生能力,提高机体非特异性免疫机能;加强体质、提高动物的抗应激、改善消化吸收功能、增加饲料利用率。作为饲料添加剂在育肥牛、断乳仔猪、肉鸡等应用较多,在畜牧生产中有较高的应用价值。本研究拟用添加三种不同水平的巴尔麦氏的饲粮饲喂15周龄至45周龄的罗曼父母代蛋种鸡,来探究日粮中不同水平的巴尔麦氏对蛋鸡生产性能及抗病能力的影响。试验开始于2013年3月2日,9月29日结束,在伊犁州奶牛场蛋种鸡场进行,试验期210天。试验选用15周龄的罗曼父母代蛋种鸡400羽,随机分为4个组,每组100羽。4个组均在同一栋鸡舍,采用3层阶梯式笼养,每笼3羽,各组鸡笼上下位置均等。对照组的饲喂采用基础日粮,分别在试验1组、2组和试验3组饲喂基础日粮的基础上添加巴尔麦氏1‰、2‰、3‰的量。试验过程中,记录统计对照组、试验组产蛋率分别达到5%和50%时,蛋鸡的平均日龄、蛋重及体重。并每周统计计算产蛋率、平均蛋率、采食量、料蛋比等。当各组达到产蛋高峰期以后(约27周龄后)连续收集4周种蛋,3d孵化1次,21d出雏,计算出各组种蛋的受精率、受精蛋孵化率和健雏率,并在各组产蛋率达到50%时,运用鸡全血平板凝集试验对各组鸡群进行沙门氏菌感染检测,每月监测一次,计算阳性率、阴性率。得到下列几种主要的试验结果。通过试验结果表明:18~22周龄,试验组各组产蛋率均高于对照组(P㧐0.05),而试验1、2组略高于试验3组及对照组;平均蛋重试验3组增加,差异显著(P㩳0.05),在对照组与试验1组、2组中料蛋比有所下降,而试验3组的料蛋比显著增高(P㩳0.05)。23~26周龄时,在产蛋率、平均蛋重、料蛋比上对照组与试验组各组之间并差异不显著(P㧐0.05),试验2组产蛋率有所提高,而料蛋比下降;日采食量试验3组与其他各组相比,明显增加(P㩳0.05)。27~30周龄时,试验2组的产蛋率显著提高,料蛋比明显降低(P㩳0.05),而试验3组的产蛋率与其他各组相比,显著降低(P㩳0.05),料蛋比升高,但差异不显著(P㧐0.05);平均蛋重试验3组明显高于对照组,差异显著(P㩳0.05),但开产日龄试验组与对照组相比较晚;在繁殖性能的指标上,试验组与对照组相比,差异不显著。通过在罗曼父母代蛋种鸡日粮中添加不同水平巴尔麦氏,试验得出巴尔麦氏可以提高采食量,提高饲料报酬,从而改善其增重。试验各组随着鸡沙门氏菌检测净化技术的应用,阳性检出率总体呈现下降的趋势。且日粮中添加2‰巴尔麦氏能够提高鸡群整齐度,促进生长。还可以降低料蛋比,提高产蛋率,提高鸡的抗病性。
[Abstract]:Balmac's is a kind of biological feed additive with high efficiency, alkaline ionization and immune enhancer. It contains SiGe Ge Agna Agna TiTiZN Zn 2 + Fe 2, etc. It can enhance the immunity of organism and the ability of tissue regeneration of biological cells, and improve the nonspecific immune function of the body.Strengthen physique, improve animal anti-stress, improve digestion and absorption function, increase feed utilization ratio.As a feed additive, it is widely used in fattening cattle, weaning piglets and broilers, and has high application value in livestock production.In order to investigate the effects of different levels of Barmac's diet on the performance and disease resistance of laying hens, three different levels of Barm's diet were used to feed Roman parental egg broilers aged from 15 weeks to 45 weeks of age in order to explore the effects of different levels of Barmac's diet on the performance and disease resistance of laying hens.The experiment began on March 2, 2013, and ended on September 29, 2013. The experiment was conducted in Yili Dairy Farm for 210 days.A total of 400 15week-old Roman parents were randomly divided into 4 groups (100 in each group). The four groups were raised in the same coop with 3 feathers in each cage, and the position of each group was equal.In the control group, the basal diet was used, and the basal diet was added to the basal diet in the first group and the third group respectively. The quantity of Barm's 1 鈥，
