This study was conducted to evaluate the effects of dietary supplementation of seed (SMS) extract on the growth performance, nutrient digestibility, fecal noxious gas emission, and hematology parameters in weaned piglets. A total of 120, 21-day-old weaned piglets ([Yorkshire × Landrace] × Duroc) were randomly assigned to 3 groups based on the average initial body weight (6.46 ± 0.45 kg). There were 8 replicate pens per treatment and 5 pigs (mixed sex) per pen. The experimental period was 42 days. Dietary groups included a basal diet, and a basal diet supplemented with 0.05% or 0.10% SMS extract. Feeding weaned piglets with SMS extract containing diet significantly increased average daily gain and average daily feed intake. Additionally, the supplementation of SMS extract had no significant effects on nutrient digestibility, serum hematology, and fecal noxious gas emission parameters. We considered that the supplementation of SMS extract had positive effects on the voluntary feed intake in weaned piglets, thus improving growth performance.
本研究旨在评估日粮中添加种子（SMS）提取物对断奶仔猪生长性能、养分消化率、粪便有害气体排放和血液学参数的影响。总共120头21日龄的断奶仔猪（[约克夏×长白]×杜洛克）根据平均初始体重（6.46±0.45千克）随机分为3组。每个处理有8个重复栏，每个栏中有5头猪（混合性别）。试验期为42天。日粮组包括基础日粮，以及添加0.05%或0.10% SMS提取物的基础日粮。用含SMS提取物的日粮饲喂断奶仔猪显著提高了平均日增重和平均日采食量。此外，添加SMS提取物对养分消化率、血清血液学和粪便有害气体排放参数没有显著影响。我们认为，添加SMS提取物对断奶仔猪的自愿采食量有积极影响，从而改善了生长性能。
