摘要

本试验以杂交品种“Kobb-500”肉鸡为试验对象,研究了不同投喂酸化剂FRA LBB DRY的剂量、形式和类型对肉鸡肠道菌群含量、滞留量和生产能力的影响。第一个实验用三组肉仔鸡进行,每组46只鸡。第一组肉鸡为对照组。试验组饲喂常规混合饲料。第二组和第三组在相同的混合饲料中添加FRA - LBB - DRY饲料的酸化剂;第二组每吨饲料3公斤,第三组每吨饲料5公斤。第二个试验采用6个相似的肉鸡类似物组,每组100只鸡,雌雄比例相等。试验结束后,6个组均按年龄分组饲喂等量的全营养混合饲料。就饮酒而言,两组人的补水情况不同。第一组饲喂白开水,2、3、4、5组肉鸡饲喂FRA - LBB - DRY酸化剂,添加量分别为1、0;1、33;分别为1,66和2,0 ml/L。最后一组,即第六组,给予1 ml/L的诺福克液体抗生素。细菌学实验表明,在饲喂不同剂量的干酸化剂7天后,与第一组相比,第二组和第三组肉鸡的粪便样本中含有较少的不良微生物群,特别是大肠杆菌减少了26.7%和29.0%,肠球菌减少了21.4%和24.7%,差异很大(P< 0.01)。同时,检测样品中有益菌群如双歧杆菌和乳酸菌浓度较高。与未检测样本相比,差异为18.3 ~ 24.1% (P< 0.01)和16.5 ~ 17.8% (P< 0.05)。在第2、3、4、5组水中分别添加酸化剂FRA LBB DRY 1、0;1、33;1、66、2 ml/l水分别使大肠杆菌减少12.7% (P< 0.05)、17.4% (P< 0.01)、18.8% (P< 0.01)、16.0% (P< 0.05),肠球菌减少14.9%;20日,9;17、8;高概率增加16.9% (P< 0.01),同时双歧杆菌数量增加19.1%;20日,6;乳酸菌分别为17.9%和21.3% (P< 0.01)和14.4%;16、5;15日,8;12.4% (p < 0.01)。肠道菌群含量的变化对营养物质的消化和加工有明显的积极作用,从而提高了酸化剂处理肉鸡的维持力和生产能力。在第一次试验中,肉鸡的离群率几乎是对照组的三分之一。在第二个试验中,试验组肉鸡的饲养量比对照组高出6-7个百分点。在混合饲料中添加酸化剂也提高了鸟类的生长速度。例如,在第一次试验中,第2、3试验组的1只肉仔鸡的体质量比对照组增长了5.05、5.23 %。在第2次试验中,2 ~ 5组的绝对增重和日增重均比对照组高出3.8 ~ 4.5个百分点。就每增重1公斤的食用量而言,两项试验均表明,试验2 - 3组和试验2 - 5组的食用量比对照组少3,4和2,7 - 4,3 %。在显示实验效率的客观指标中,我们可以使用欧洲效率指数,在第一次和第二次实验中,该指数为37,8-38-6,32,0-50,比对照组高1分。除了酸化剂,该实验还将测试诺福克抗生素的使用效果,诺福克抗生素是在第二次实验中给第6组的鸟类服用的。数据表明,在绝对增重和日增重、饲料系数、畜禽滞留率和欧洲效率指数方面,第6组的鸡在所有类别上都明显超过对照组,但在几乎所有类别上都不及其他试验组。这些数据让我们得出结论,我们很有可能将抗生素换成酸化剂,而生产力几乎没有损失。综上所述,本微生物学研究的数据表明,在固定饲料中加入酸化剂对肉鸡肠道菌群有积极影响,这很可能是改善消化和消费过程的因素之一,从而改善了家禽的饲养。通过对试验结果的综合评价,肉鸡使用干液酸化剂FRA LBB dry的最佳投加量为混合饲料3kg/t或水1,33 - 1,66 ml/l。 从进一步发展的角度来看,这项研究可能会寻求一种不同的生化性质和更有效的酸化剂。关键词:肉鸡,酸化剂,抗生素,肠道菌群,产量

Contents of the microflora of the intestine, retention and productivity of broiler chickens in accordance with different types and quantities of the acidifier
In two scientific-field experiments with broiler chicken cross-breeding ”Kobb-500", the goal was set to learn the influence of different dosages, forms and types of feeding the acidifier FRA LBB DRY onto the contents of the microflora of intestine, retention and productivity of broiler chickens. The first experiment was done using three groups-analogs of broiler chickens, 46 birds per group. The broiler chickens of the first group were the control group. This group was fed a regular mixed feed. The second and third groups were fed the same mixed feed with an addition of the acidifier of FRA LBB DRY feed added; 3kg per ton of feed for the 2-nd, and 5 kg per ton for the third group. The second experiment was done using 6 similar groups-analogs of broiler chickens, 100 birds per group, with an equal ratio of male to female chicken. Throw-out the experiment all six groups were fed the same amount of fully nutritional mixed feed, in accordance with their age growth groups. As far as drinking went, the groups were hydrated differently. Birds of the first group were getting plain water, broiler chickens of the 2, 3, 4, and 5 groups were getting a mix of FRA LBB DRY acidifier in the quantities of 1,0; 1,33; 1,66 and 2,0 ml/L accordingly. The last group, group 6, was getting a dose of liquid Norfolk antibiotic in the quantity of 1 ml/L. As the bacteriological experiments have shown, after 7 days of feeding different doses of dry acidifier, the stool sample of the second and third groups of broiler chickens, when compared to the first group, had shown to contain less undesirable microflora in particular Escherichia coli – by 26,7 and 29,0 %, enterococcus by 21,4 and 24,7 % with a high probability of difference (P<0,01). At the same time the test samples contained higher concentration of useful microflora such as Bifidobacterium and lacto bacteria. The difference, when compared to the- test sample, was 18,3–24,1 % (P<0,01) and 16,5-17,8 % (P<0,05). In the second experiment adding acidifier FRA LBB DRY to water for the 2, 3, 4, and 5-th groups by 1,0; 1,33; 1,66 and 2 ml/l of water had caused a decrease of escherichia coli by 12,7 % (P<0,05), 17,4 % (P<0,01), 18,8 % (P<0,01) and 16,0 % (P<0,05), enterococcus by 14,9; 20,9; 17,8; and 16,9 % with a high degree of probability (P<0,01), at the same time increasing the amount of bifidobacteria by 19,1; 20,6; 17,9 and 21,3 %, (P<0,01) and lactobacteria by 14,4; 16,5; 15,8; 12,4 % (P<0,01). The changes that had taken place in the contents of the microflora of intestine obviously had a positive effect on digestion and processing of nutrients, which, as a result, had improved the upkeep and productivity of the broiler chickens which were exposed to the acidifier. In the first experiment departure of the broiler chickens was almost three times less than that of a control group. In the second experiment the upkeep of broilers in test groups was larger than the control by 6–7 absolute percent. Adding an acidifier into the mixed feed also increased the rate of growth in birds. Case in point, in the first experiment the growth of the body mass of one broiler of the 2-nd and 3-rd test groups was by 5,05 and 5,23 % larger than the control group. In the second experiment, both absolute and daily weight gains of 2–5-th groups were by 3,8-4,5 % larger than those of the control group. As far as comparing the expenses in terms of quantities of food per 1 kg of gains, both experiments have shown that test groups 2–3 and 2–5 consumed 3,4 and 2,7–4,3 % less than the control group. Among the objective measures that show the efficiency of the experiment, we can use the European efficiency index, which in first and second experiments was 37,8-38-6, and 32,0-50,1 points higher than the control group. Alongside with the acidifier, the experiment was also set to text the effectiveness of the use of the Norfolk antibiotic, which was given to the birds in group 6 of the second experiment. The data had shown that by absolute and daily weight gain, feed conversion, livestock retention, and European efficiency index, the birds in the 6th group definitely surpassed the control group in all categories, but fell short of the other experiment groups in almost all categories. This data lets us conclude that there is a good possibility that we can exchange the antibiotics for acidifier, with little to no loss in productivity. In summary, the data of this microbiological research shows that including acidifier into a fixed feed has a positive impact on the broiler chicken intestines microflora, which could quite possibly be one of the factors that improves the digestion and consumption process and an improved upkeep of the birds as a result. By the general evaluation of the results of the experiment, the optimal dosage of dry and liquid acidifier FRA LBB DRY for the broiler chickens can be considered 3kg/tons of mixed feed or 1,33 –1,66 ml/l of water. As a perspective of further development, the research might look into a search of acidifiers of a different biochemical nature and of a more potent action. Key words: broiler chickens, acidifier, antibiotic, microflora of the intestines, productivity.
