双孢蘑菇菌种基质改进的研究

本文报导了用于双孢蘑菇菌种制种基质材料的研究。结果证明：平菇生产下脚料是替代棉籽壳制作蘑菇菌种的好材料,其菌种质量与棉籽壳菌种无差别,大大地降低了菌种生产成本。     

大豆荚壳中类黄酮提取工艺及其抑杀线虫活性的研究

阐述从大豆荚壳中提取类黄酮的工艺及其抑杀根结线虫的应用效果.通过正交设计,确定了大豆类黄酮的最佳提取工艺条件为乙醇浓度80%,提取温度70℃,乙醇与大豆荚壳1∶10,回流提取24 h,提取率可达8.58%,显著高于次佳工艺.对根结线虫抑杀效果的测定表明：类黄酮粗提物对南方根结线虫J2有很强的毒杀效果,且随使用浓度增大而增强,1.5 μg·mg^-1类黄酮提取物处理,线虫的校正死亡率可达50%以上;对虫卵孵化有一定的抑制作用,但孵化抑制率都在50%以下.     

广东雷州杂草稻黑壳基因Bh4和红皮基因Rc的基因型鉴定

为测定雷州杂草稻的黑色颖壳基因Bh4和红色果皮基因Rc的基因型,本研究对雷州10个杂草稻群体的100个单株的种子的颖壳和果皮颜色进行表型观察,同时通过PCR扩增及序列分析对Bh4和Rc的基因型进行鉴定。结果表明,雷州杂草稻中黑色颖壳和黄色颖壳的种子几乎各占一半,果皮颜色则以红色为主,有少量白色和浅红色果皮的种子。雷州杂草稻的Bh4和Rc的基因型与表型鉴定结果一致。57份黑色颖壳杂草稻的Bh4基因型为39个野生型和18个杂合型,25份黄色颖壳和18份黄色带黑斑颖壳杂草稻的Bh4基因型均为缺失22 bp的突变型;90份红色果皮杂草稻的Rc基因型为73个野生型和17个杂合型,4份白色和6份浅红色果皮杂草稻的Rc基因型均为缺失14 bp的突变型。本研究为分析雷州杂草稻的Bh4和Rc基因的来源提供了分子基础。

Effect of organic acids–essential oils blend and oat fiber combination on broiler chicken growth performance,blood parameters,and intestinal health

This study evaluated the effect of organic acids–essential oils blend with or without oat hulls (OH) on growth performance, organ weights, blood parameters, gut morphology, microbiota, and short-chain fatty acids (SCFA) in broiler chickens. Day-old broiler chickens were randomly allocated to 4 dietary treatments consisting of 1) a corn-soybean meal-wheat based diet (BAS), 2) BAS + 0.05% bacitracin methylene disalicylate (BMD), 3) BAS + protected organic acids–essential oils at 300 g/1,000 kg of feed (OE), and 4) BAS + protected organic acids–essential oils at 300 g/1,000 kg of feed + 3% OH (OEOH), in 8 replicate groups. Feeding was in starter (d 0 to 14), grower (d 14 to 24), and finisher (d 24 to 36) phases. Body weight (BW), feed intake (FI), feed conversion ratio (FCR), and mortality were determined weekly. On d 36, 8 chickens per treatment were sampled for blood biochemistry, organ weights, cecal SCFA production, and microbiota. Treatments had no effect on FI and FCR at all phases. Both OE and OEOH treatments reduced (P < 0.001) the body weight gain of birds at the starter phase. Birds fed the OEOH treatment had higher (P < 0.001) gizzard weight, while those offered the BMD diet showed a tendency (P = 0.08) to have higher cecal weight. Birds in the OEOH treatment recorded increased ileal villus height and villus height-to-crypt depth ratio, as well as reduced duodenal crypt depth, while birds in the OE treatment had increased jejunal villus height and villus height-to-crypt depth ratio. Both OEOH and OE treatments increased the number of goblet cells produced in the duodenum and jejunum. Treatments had no effect on SCFA concentrations. Birds in the OE treatment recorded the lowest concentration of blood urea (P = 0.05) and cholesterol (P < 0.05). Both OE and OEOH treatments increased (P < 0.05) the relative abundance of potentially beneficial bacteria in the genus Firmicutes_unclassified, Ruminococcus, Turicibacter, and Erysipelotrichaceae_unclassified, while reducing (P < 0.001) the relative abundance of potentially harmful Coprobacillus. Conclusively, both protected organic acids–essential oils blend and its combination with oat fibers show potential as tools to achieve antibiotics reduction in broiler production.
