The study aims to understand the effect of new antibiotic-substituting supplements in feeding chickens of the Hisex Brown cross in industrial conditions.
A total of 216 hatched chicks were randomly selected and distributed into Control, Test I, and Test II groups, with 3 replicates of 24 birds in three treatments.
At the end of the experiment, BW of T1/T2 birds was higher by 6.12% ( <0.01) and 10.29% (0.001) than CON. In comparison with the control hens, T1/T2 birds had a higher feed conversion rate and digestibility of nutrients. The blood indicators of T1/T2 hens exceeded those in control. Prebiotic supplementations were positively influenced in the immune indices of birds. IgA, IgG, IgM increased in groups T1/T2. Similar regularity was found in the natural resistance of chicks fed S1/S2. In the caecum, the number was higher than in CON by 17.03% (0.01) in T1 and by 18.47% (0.01)-in T2; -by 17.94 (0.001) and 19.09% (0.01), respectively; at the same time, the number of decreased by 21.05% (0.01) and 24.21% (0.01). The concentration of emitted excreta noxious gases decreased: ammonia by 22.40%-24.95% (0.01); hydrogen sulfide by 10.67%-16.00% (0.01); and mercaptans by 12.90%-17.74% (0.05).
These findings support the use of lactulose-based supplements as antibiotic alternatives to improve production in poultry farming and to reduce the toxic load on the environment.
本研究旨在了解新型抗生素替代补充剂在工业化条件下饲养海赛克斯褐壳蛋鸡杂交品种中的效果。
共随机选取216只孵化出的雏鸡，分为对照组、试验一组和试验二组，三种处理各3个重复，每组24只鸡。
实验结束时，试验一组/试验二组鸡的体重分别比对照组高6.12%（P<0.01）和10.29%（P<0.001）。与对照母鸡相比，试验一组/试验二组鸡的饲料转化率和养分消化率更高。试验一组/试验二组母鸡的血液指标超过对照组。益生元补充剂对鸡的免疫指标有积极影响。试验一组/试验二组中免疫球蛋白A、免疫球蛋白G、免疫球蛋白M增加。在饲喂S1/S2的雏鸡的天然抵抗力方面也发现了类似规律。在盲肠中，试验一组的数量比对照组高17.03%（P<0.01），试验二组高18.47%（P<0.01）；[此处原文缺失部分内容]分别高17.94%（P<0.001）和19.09%（P<0.01）；同时，[此处原文缺失部分内容]数量分别下降了21.05%（P<0.01）和24.21%（P<0.01）。排出的排泄物有害气体浓度降低：氨气降低22.40%-24.95%（P<0.01）；硫化氢降低10.67%-16.00%（P<0.01）；硫醇降低12.90%-17.74%（P<0.05）。
这些发现支持使用基于乳果糖的补充剂作为抗生素替代品，以提高家禽养殖产量并减少对环境的毒性负荷。
