摘要:

本试验旨在研究饲粮中添加有效微生物(EM)对BALB/C小鼠生长性能、养分消化率和粪便氨气排放量的影响。选取120只4周龄BALB/C小鼠,雌雄各60只,随机分为4组,每组6个重复(雌雄各3个重复),每个重复5只小鼠。EM在每组(Ⅰ、Ⅱ、Ⅲ、Ⅳ组)添加量分别为0、200、400、600 mg/kg。试验持续7周,预试期1周、正式期6周。结果表明,饲粮添加400和600 mg/kg的EM均能显著提高BALB/C小鼠干物质和粗脂肪的消化率(P<0.05),但对于其他养分消化率无显著影响(P>0.05)。饲粮添加EM对BALB/C小鼠生长性能及粪便氨气排放量无显著影响(P>0.05)。因此,在饲粮中添加EM可以改善BALB/C小鼠的养分消化率(干物质和粗脂肪),建议添加量为400 mg/kg,但不能减少氨气的排放。

Abstract:

The purpose of this study is to determine the effects of dietary supplementation of effective microorganisms (EM) on growth performance, nutrient digestibility and fecal ammonia emission of BALB/C mice. A total of 120 BALB/C mice (4-week-old) with 60 males and 60 females were randomly divided into 4 groups with 6 replicates in each group (3 replicates for male and 3 replicates for female) and 5 mice in each replicate. EM added into diet of each group (groupⅠ,Ⅱ,Ⅲ, and Ⅳ) was 0, 200, 400 and 600 mg/kg, respectively. The experiment lasted for 7 weeks, including one week of adaption period and 6 weeks of experimental period. The results showed that dietary addition of 400 and 600 mg/kg EM significantly increased dry matter and ether extract digestibility of BALB/C mice (P<0.05), but had no significant effect on the digestibility of other nutrients (P>0.05). EM had no significant effect on the growth performance and fecal ammonia emission of BALB/C mice (P>0.05). It is concluded that dietary supplementation of EM could improve nutrient digestibility (dry matter and ether extract) of BALB/C mice and could not reduce ammonia emission, and the recommended supplementation is 400 mg EM per kilogram diet.

Key words: effective microorganisms, BALB/C mice, growth performance, nutrient digestibility, ammonia emission
