Abstract A study was conducted to evaluate the effects of dietary supplementation of different levels of coated sodium butyrate (CSB) on growth performance, nutrient digestibility, faecal and intestinal coliform and lactic acid bacteria counts, gas emission and small intestinal villi length in weaning pigs. A total of 160 weaning pigs [(Landrace x Yorkshire) x Duroc, 28 days old] with an average initial body weight (BW) of 7.04 ± 1.15 kg were randomly allotted to 4 treatments (8 replicates per treatment with 5 pigs; 3 barrows and 2 gilts per replicate pen) according to their initial body weight for a 6-week trial in three phases. Treatments consisted of corn-soybean meal-based diet with slight reduction in lactose (approximately 5 %) as well as sodium content relative to National Research Council (NRC, 2012) requirement as the control (CON) and CON diet supplemented with low dose CSB (0.5 g/kg feed), medium dose CSB (1.5 g/kg feed for first 3 weeks followed by reduction to 0.75 g/kg feed thereafter) and high dose CSB (3 g/kg feed for first 3 weeks followed by reduction to1.5 g/kg feed thereafter). As a result of this study, the supplementation of increasing levels of CSB increased final BW (linear, P = 0.04, quadratic P = 0.02 effects) at day 42, linearly increased average daily gain (ADG) and gain: feed (G:F) ratio (P = 0.05, P = 0.01 respectively) during day 8−21. The ADG showed trends (P = 0.073) in increment and a significant linear increase in G:F (P

在低营养日粮中添加涂层丁酸钠可提高断奶仔猪的生产性能并对绒毛高度以及粪便和食糜细菌组成产生积极影响

摘要 本研究旨在评估日粮添加不同水平的包衣丁酸钠(CSB)对断奶仔猪生长性能、营养消化率、粪便和肠道大肠菌群和乳酸菌数量、气体排放和小肠绒毛长度的影响。将 160 头平均初始体重 (BW) 为 7.04 ± 1.15 kg 的断奶猪 [(Landrace x Yorkshire) x Duroc,28 天] 随机分配到 4 个处理组(每个处理组 8 个重复,5 头猪;3 只手推车)和每个重复栏 2 头小母猪)根据它们的初始体重进行 6 周的三个阶段试验。处理包括基于玉米 - 豆粕的饮食,相对于国家研究委员会(NRC,2012) 要求作为对照 (CON) 和 CON 饮食补充低剂量 CSB(0.5 g/kg 饲料)、中剂量 CSB(前 3 周为 1.5 g/kg 饲料,然后减至 0.75 g/kg 饲料)和高剂量 CSB(前 3 周 3 g/kg 饲料,然后减至 1.5 g/kg 饲料)。作为这项研究的结果,在第 42 天,增加 CSB 水平的补充增加了最终 BW(线性,P = 0.04,二次 P = 0.02 效应),线性增加了平均日增重 (ADG) 和增重:饲料 (G:F ) 比率(分别为 P = 0.05,P = 0.01)在第 8-21 天。ADG 显示出增量趋势 (P = 0.073) 和 G:F (P 此后 75 g/kg 饲料)和高剂量 CSB(前 3 周 3 g/kg 饲料,然后减至 1.5 g/kg 饲料)。作为这项研究的结果,在第 42 天,增加 CSB 水平的补充增加了最终 BW(线性,P = 0.04,二次 P = 0.02 效应),线性增加了平均日增重 (ADG) 和增重:饲料 (G:F ) 比率(分别为 P = 0.05,P = 0.01)在第 8-21 天。ADG 显示出增量趋势 (P = 0.073) 和 G:F (P 此后 75 g/kg 饲料)和高剂量 CSB(前 3 周 3 g/kg 饲料,然后减至 1.5 g/kg 饲料)。作为这项研究的结果,在第 42 天,增加 CSB 水平的补充增加了最终 BW(线性,P = 0.04,二次 P = 0.02 效应),线性增加了平均日增重 (ADG) 和增重:饲料 (G:F ) 比率(分别为 P = 0.05,P = 0.01)在第 8-21 天。ADG 显示出增量趋势 (P = 0.073) 和 G:F (P
