复合有益菌及其与中药复合制剂对饲料霉变的抑制效果研究

为探讨复合有益菌以及复合有益菌和中药复合制剂对饲料霉变的抑制效果,进行了霉菌总数抑制对比试验、黄曲霉毒素抑制对比试验。试验组在原料中添加复合有益菌（0.2%）、复合有益菌和中药复合制剂（0.2%）,厌氧消化6~8个月。结果表明：复合有益菌和中药复合制剂厌氧消化饲料,使霉菌总数降低50.71%~97.53%,可以有效抑制基质的霉变,但对严重发霉的基质抑制效果不佳;发霉全价饲料中,添加复合有益菌组黄曲霉毒素B1（AFTB1）含量为1.15μg/kg,复合有益菌与中药复合组AFTB1含量为1.23μg/kg,与对照组（1.60μg/kg）相比差异显著,复合有益菌能降低黄曲霉毒素的含量,改善饲料的微生态环境。

复合有益菌剂对工厂化大菱鲆育苗水净化效果研究

On the basis of purifying effect of single-strain probiotic bacteria on water of intensive turbot breeding,the purifying effect of multi-strain bacteria product was studied.The results of experiments showed that the free multi-strain mixed bacteria had better purifying effect on turbot breeding water than that of any single-strain bacteria.this phenomenon can be explained with the principle of " bio-pump".The immobilized multi-strain probiotics product,bio-film,also showed excellent purifying effect on water of turbot breeding.The removal rates of COD and ammonia in 5 days were up to 73.1% and 80.0%,respectively.The concentration of nitrite kept low,which indicated most ammonia had been transformed into nitrate and accumulation of harmful intermediate product-nitrite was decreased.This paper supplied theoretical and technical foundation for saving sea water through bio-purification of wastewater from marine fish culture.

有益菌和中药协同对家兔生长性能及理化指标的影响

为探讨有益菌和中药复合制剂对家兔生长性能的影响,选70～80日龄体重相近的德国大白兔30只,随机分成对照组、试验组。试验组在基础日粮中添加3%的有益菌和中药复合制剂,饲喂42d。试验组与对照组相比,饲料转化率提高39.34%;家兔腹泻率减少80%,死亡率降低75%;屠宰测定各项指标差异不显著(P>0.05);家兔腿肌的精氨酸、氨的含量差异显著(P<0.05),蛋白质、氨基酸总量有提高趋势,差异不显著(P>0.05);血清总蛋白、血清葡萄糖含量显著提高,血清总胆固醇、低密度脂蛋白等指标有降低的趋势。添加有益菌和中药复合制剂协同作用可改善饲料适口性,提高饲料报酬、养兔效益,调节血脂,改善肉质和口感。
