A 29-d trial was conducted to evaluate the effects of dietary methyl sulfonyl methane (MSM) supplementation on growth performance, meat quality, nutrient digestibility, excreta microbiota, excreta gas emission, and blood profiles in broilers. A total of 816 1-day-old male Ross 308 broilers (44 ± 0.44 g) were assigned to 4 dietary treatments, composed of 12 replicates with 17 birds per replicate. The 4 treatments were: 1) CON, basal diet; 2) S1, CON + 0.05% MSM; 3) S2, CON + 0.10% MSM; 4) S3, CON + 0.20% MSM. In the current study, body weight (BW) on d 14 and 29 showed significant improvement as dietary MSM increased from 0.05% to 0.20% (P < 0.05). During d 1 to 14 and overall, higher (P < 0.05) body weight gain (BWG) and lower feed conversion ratio (FCR) were observed in broilers fed MSM diets. Between d 15 and 29, higher (P < 0.05) BWG was observed in broilers fed MSM diets. Redness (a*) was increased linearly (P < 0.05) in broilers fed MSM diets. On d 3, 5, and 7, drip loss was decreased linearly (P < 0.05) in broilers fed MSM diets. Lactobacillus and E. coli were effected linearly (P < 0.05) in broilers fed MSM diets. Alanine aminotransferase (ALT), white blood cells (WBC) and lymphocytes were improved linearly (P < 0.05) in broilers fed MSM diets. In conclusion, dietary supplementation MSM has positive effects on growth performance, meat quality, excreta microbiota, and blood profiles in broilers.
一项为期 29 天的试验评估了膳食甲基磺酰甲烷（MSM）补充对肉鸡生长性能、肉质、养分消化率、粪便微生物群、粪便气体排放和血液指标的影响。总共 816 只 1 日龄雄性罗斯 308 肉鸡（44±0.44g）被分配到 4 种饮食处理组，每组 12 个重复，每个重复 17 只鸡。这 4 种处理组为：1）CON，基础日粮；2）S1，CON+0.05%MSM；3）S2，CON+0.10%MSM；4）S3，CON+0.20%MSM。在本研究中，随着日粮 MSM 从 0.05%增加到 0.20%，第 14 天和第 29 天的体重（BW）显著提高（P<0.05）。在第 1 天至第 14 天和整个试验期间，饲喂 MSM 日粮的肉鸡表现出更高的（P<0.05）体重增重（BWG）和更低的饲料转化率（FCR）。在第 15 天至第 29 天期间，饲喂 MSM 日粮的肉鸡的 BWG 更高（P<0.05）。饲喂 MSM 日粮的肉鸡的红色度（a*）呈线性增加（P<0.05）。在第 3、5 和 7 天，饲喂 MSM 日粮的肉鸡的滴水损失呈线性降低（P<0.05）。饲喂 MSM 日粮的肉鸡的乳酸菌和大肠杆菌呈线性影响（P<0.05）。饲喂 MSM 日粮的肉鸡的丙氨酸氨基转移酶（ALT）、白细胞（WBC）和淋巴细胞呈线性改善（P<0.05）。总之，日粮补充 MSM 对肉鸡的生长性能、肉质、粪便微生物群和血液指标有积极影响。
