In-feed probiotics are becoming attractive alternatives to antibiotics in the poultry industry due to the ever-growing strict prohibitions on antibiotic growth promoters (AGP) in animal production.
The study was conducted to investigate the effects of and on the growth performance of 120 day-olds randomly selected Sasso dual-purpose chicken. They were divided into four groups with two replicates per group and 15 chicks per replicate. The treatments were T (control), T (supplement diet with 4g probiotic), T (supplement diet with 2g probiotic), T (supplement diet with 1g probiotic). The experimental feeding trials were conducted after two weeks adaptation period.
The present findings revealed that the chickens supplemented with species probiotics during the first week of age have shown higher body weight than control ( < 0.05). The feed intake of week one of T and T were significantly higher (< 0.05) than the T (control). However, there was no significant difference (> 0.05) in feed intake in the 2, 3, 4, and 5 weeks of all treatment groups. The present result showed that there was a significant body weight gain (< 0.05) in all probiotic fed groups than the control group. The highest body weight gain was observed in chickens found in the T4 treatment group. Whereas the body weight gains significantly higher and improved the feed conversion (<0.05) in the T and T than the T (control). However, the feed conversion ratio was significantly influenced by probiotic inclusion in T as compared to the control group.
Overall, the results suggest that and have a positive effect on the growth performance of broilers.
由于动物生产中对抗生素生长促进剂（AGP）的禁令日益严格，饲料中添加益生菌正成为家禽业中抗生素的有吸引力的替代品。
本研究旨在调查[具体益生菌种类1]和[具体益生菌种类2]对120只随机挑选的1日龄萨索两用鸡生长性能的影响。它们被分为四组，每组两个重复，每个重复15只雏鸡。处理组分别为T1（对照组）、T2（在饲料中添加4克益生菌）、T3（在饲料中添加2克益生菌）、T4（在饲料中添加1克益生菌）。在两周的适应期后进行实验性饲养试验。
目前的研究结果表明，在1周龄时添加[具体益生菌种类1]的鸡体重高于对照组（P<0.05）。T2和T3组第1周的采食量显著高于T1组（对照组）（P<0.05）。然而，所有处理组在第2、3、4和5周的采食量没有显著差异（P>0.05）。目前的结果表明，所有添加益生菌的组体重增加显著（P<0.05），高于对照组。在T4处理组的鸡中观察到最高的体重增加。与T1组（对照组）相比，T2和T3组的体重增加显著更高，饲料转化率得到改善（P<0.05）。然而，与对照组相比，T4组中益生菌的添加对饲料转化率有显著影响。
总体而言，结果表明[具体益生菌种类1]和[具体益生菌种类2]对肉鸡的生长性能有积极影响。
