We examined the effects of sodium butyrate and flavors on feed intake of lactating sows and growth performance of piglets. A total of 52 primiparous sows (Large White) were randomly divided into four treatments (n = 13) and received 6 g/kg sodium butyrate (SB), fruit-milk (FM) flavor and fruit-milk-anise (FMA) flavor with pair feeding to the mothers receiving the control diet. The feeding trial lasted for 29 days, including 21 days of nursing and 8 days of post-weaning period, respectively. The nursing and weaning piglets received creep diets with the same flavor or SB supplement as their mother. The results showed that FMA flavor increased average daily feed intake (ADFI) of lactating sows (P < 0.01), as well as improved litter weight gain (P = 0.05) and ADFI (P < 0.01) of nursing pigs among treatments. Indeed, greater ADFI and average daily gain of weaning piglets for the initial 8 days after weaning was observed in the FMA group compared with those in the control group (P < 0.01). These findings indicated that adding FMA flavor was superior to SB for increasing feed intake of lactating sows and improving growth performance of piglets.
我们研究了丁酸钠和风味剂对泌乳母猪采食量及仔猪生长性能的影响。总共52头初产母猪(大白猪)被随机分为四个处理组(每组n = 13),分别接受6 g/kg丁酸钠(SB)、果奶(FM)风味剂和果奶茴芹(FMA)风味剂,并对接受对照日粮的母猪进行配对饲养。饲养试验持续29天,分别包括21天的哺乳期和8天的断奶后期。哺乳仔猪和断奶仔猪采食的开食料具有与其母亲相同的风味或SB添加物。结果表明,FMA风味剂增加了泌乳母猪的平均日采食量(ADFI)(P < 0.01),同时提高了各处理组哺乳仔猪的窝增重(P = 0.05)和ADFI(P < 0.01)。实际上,与对照组相比,FMA组断奶仔猪在断奶后最初8天的ADFI和平均日增重更高(P < 0.01)。这些结果表明,添加FMA风味剂在增加泌乳母猪采食量和提高仔猪生长性能方面优于SB。
