【摘要】本文探究了日粮添加丁酸钠对仔猪断奶和生产性能的影响。试验选取40只仔猪(9.2±1.4 kg)平均分成两组,对照组(CTR组):喂食基础日粮;丁酸钠组(SB组):基础日粮+0.8g/kg丁酸钠基础日粮添加了0.5g/kg甲酸和1.5g/kg乳酸,试验为期56天。试验开始后记录两组仔猪每个阶段(0-14天,15-35天,36-56天,0-56天)的平均日增重(ADG),每日采食量(DFI),饲料转化率(FE)和活重(LW)。试验结果显示,在试验前两周,日粮添加丁酸钠可显著提高SB组仔猪的ADG+20; P<0.05)和DFI+16; P <0.05)。而在随后的时期(15-35天)中,与喂食基础日粮的仔猪相比,饲喂含有丁酸钠日粮的仔猪具有较高的DFI,但饲料转化率(FE)较低(分别为+ 10%和-14%; P <0.05)。35天后没有观察到仔猪相关指标的显著性变化。研究结果表明:饲喂丁酸钠可促进断奶初期仔猪适应日粮由母乳到固体饲料的转变。

Abstract
 
The purpose of the present work was to evaluate whether the addition of sodium butyrate to feed could facilitate weaning and growth response in piglets. For 56 days two groups of 20 piglets (9.2±1.4 kg LW) were fed an acidified basal diet (containing formic and lactic acid at 0.5 and 1.5 g/kg of feed, respectively) without (control group) or with sodium butyrate (SB) at 0.8 g/kg. Average daily gain (ADG), daily feed intake (DFI), feed efficiency (FE) and live weight (LW) were recorded. In the first two weeks, butyrate supplementation increased ADG (+20%; P<0.05) and DFI (+16%; P<0.05). During the subsequent period (15 to 35 days) animals fed SB had a higher DFI but lower feed efficiency (+10% and -14%, respectively; P<0.05) than animals fed the control diet. No other benefits were observed thereafter. The data presented showed that the use of sodium butyrate facilitated only the initial phase of adaptation to a solid diet in piglets.

Conclusion
 
The use of sodium butyrate facilitated only the initial phase of adaptation to a solid diet in piglets.
