An experiment was conducted to investigate the effects of Achyranthes japonica extracts (AJE) on the growth performance, nutrient digestibility, fecal microbial shedding, and fecal gas emission of growing pigs.
A total of 180 ([Landrace×Yorkshire]×Duroc) growing pigs with initial body weight (BW) of 23.94±1.54 kg were used in this study to investigate the effects of AJE as a feed additive. Dietary treatments included: i) CON (basal diet), ii) TRT1 (basal diet+0.05% AJE), and iii) TRT2 (basal diet+0.10% AJE).
As a result of the dietary supplementation of 0% to 0.10% AJE, a linear increase of BW (p<0.05) on d 21 and 42, a linear increase of average daily gain (ADG) (p<0.05) during d 21 to 42, a trend in linear increase of ADG (p<0.10) during d 0 to 21 and d 0 to 42, a linear increase of gain to feed ratio (G:F) (p<0.05) during d 0 to 42, and a tendency in the linear increase of G:F during d 21 to 42 were observed in this study. Additionally, dietary supplementation of 0% to 0.10% AJE had a linear increase (p<0.05) on the apparent total tract digestibility of dry matter (DM) and energy, a linear increase (p<0.05) on lactic acid bacteria counts, a tendency in reducing (linear effect, p<0.10) coliform bacteria counts, and a linear decrease (p<0.05) in excreta H2S emission content in growing pigs.
In conclusion, the results suggested that AJE had the potential to enhance growth performance, DM and energy digestibility, and fecal lactic acid bacteria counts, and decrease the fecal coliform bacteria counts and excreta H2S emission in growing pigs.
进行一项实验，以研究日本牛膝提取物（AJE）对生长猪生长性能、养分消化率、粪便微生物排泄及粪便气体排放的影响。
本研究选用180头初始体重（BW）为23.94±1.54千克的（长白×约克夏）×杜洛克生长猪，以研究AJE作为饲料添加剂的效果。日粮处理包括：i）对照组（基础日粮），ii）处理1组（基础日粮+0.05% AJE），iii）处理2组（基础日粮+0.10% AJE）。
日粮中添加0%至0.10% AJE的结果显示，第21天和第42天体重呈线性增加（p<0.05），第21天至42天平均日增重（ADG）呈线性增加（p<0.05），第0天至21天和第0天至42天ADG有线性增加趋势（p<0.10），第0天至42天料重比（G:F）呈线性增加（p<0.05），第21天至42天G:F有线性增加趋势。此外，日粮中添加0%至0.10% AJE使生长猪干物质（DM）和能量的表观全肠道消化率呈线性增加（p<0.05），乳酸菌数量呈线性增加（p<0.05），大肠菌数量有减少趋势（线性效应，p<0.10），粪便硫化氢排放含量呈线性下降（p<0.05）。
总之，结果表明AJE有潜力提高生长猪生长性能、DM和能量消化率以及粪便乳酸菌数量，并减少粪便大肠菌数量和粪便硫化氢排放。
