大菱鲆鱼体脂肪累积调节方法研究

通过摄食生长实验来研究高植物蛋白饲料中添加牛磺酸及水解鱼蛋白对大菱鲆脂肪累积的影响。实验对照组(C)含有30%的鱼粉,高植物蛋白饲料+牛磺酸处理组(HT)使用植物蛋白替代对照组的一半鱼粉后添加0.8%牛磺酸,高植物蛋白饲料+牛磺酸+水解鱼蛋白处理组(HTPH)在HT饲料的基础上继续使用水解鱼蛋白替代7%的饲料鱼粉。室内流水系统养殖,每组4个重复。与对照组或HT组相比,HTPH组显著降低了鱼体的中性脂和肝体比。与对照组相比,HT及HTPH组均显著升高了鱼体水分含量,降低了肝脏总脂和中性脂含量。与对照组相比,肌肉总脂及极性脂仅在HTPH组显著降低。HTPH组的血清甘油三酯和胆固醇含量显著低于对照组。组织脂肪酸分析显示,HT及HTPH组有降低长链多不饱和脂肪酸含量,升高C18∶2n-6,C18∶3n-6及C18∶3n-3含量的趋势。综上,在高植物蛋白饲料中添加牛磺酸可以有效降低鱼体肝脏脂肪含量,而在此基础上继续使用水解鱼蛋白具有更好的脂肪调节效果,能够降低鱼体、肌肉、肝脏及血清中的中性脂肪及总脂肪含量。

加快河南省花生产业转型升级的对策思考

花生是我国居民食用植物油和植物蛋白的重要来源。河南省是全国花生生产第一大省,花生种植面积、产量分别占全国的1/4和1/3。在全省大田作物中,花生种植面积仅次于小麦、玉米居第三位。近年来,河南省大力推进优质花生布局区域化、经营规模化、生产标准化、发展产业化,促进花生产业转型升级,对于保障国家食用油料供给安全,促进乡村振兴和农民增收,具有十分重要的意义。

植物蛋白资源开发利用的主攻方向李超，叶含英（杭州商学院植物蛋白食品工程研究室，杭州商学院烹拉特植物蛋白集团公司）我国对植物蛋白的开发利用，具有悠久的历史，约公元前１６０年西汉孝文帝时代，淮南王刘安发明用大豆制豆腐，距今已有二千多年的历史。由于工艺原理...     

三周龄断奶仔猪对乙醇处理豆饼后饲粮的养分消化率及生长性能的测定

用７０％的热乙醇（７５℃）处理普通豆饼３０分钟。处理豆饼的粗蛋白和真蛋白含量分别比未处理豆饼低３．１和４．１个百分点。用乙醇处理豆饼或普通豆饼为唯一蛋白来源的饲粮饲喂３周龄断奶仔猪，进行２周试验。结果表明，处理豆饼饲粮的能量、粗蛋白、有机物和干物质的表观消化率均明显高于未处理豆饼饲粮。其中，粗蛋白消化率高１３．１个百分点，其他养分高７．６—７．８个百分点。然而，处理豆饼组仔猪的采食量和生长速度均低于未处理豆饼组。     

以植物蛋白为主的虹鳟的颗粒饵料

上海的三个茶新闻

1．茶饮料合格率100％ 上海市质量技术监督局6月公布了碳酸饮料、果汁及果汁饮料、茶饮料、含乳饮料、植物蛋白饮料五类预包装软饮料抽查结果，总体抽合格率为92．0％，其中茶饮料合格率为100％，植物蛋白饮料合格率为92．3％，果汁及果汁饮料合格率为91．9％，含乳饮料合格率为90．9％，碳酸饮料合格率为89．3％。针对本次产品监督抽查情况，质监部门对不合格产品的生产、经销企业限制整改，做好后处理工作。对继续生产销售不合格产品的企业严肃处理。     

饲料中添加蛋白酶AG对凡纳滨对虾生长和肌肉成分的影响

<正>鱼粉供求的日益紧张和价格上涨,使得植物蛋白源替代鱼粉的研究成为现阶段的一个热点。但植物蛋白存在较多的抗营养因子使其难以被消化利用,通过酶制剂降解这些抗营养因子,消除其抗营养特性,是提高植物蛋白消化吸收率的重要途径。目前酶制剂在畜禽饲料中已有较多的应用,但在水产饲料上的研究应用较少。     

Effects of Soybean Meal Replaced by Fermented Plant Protein Compound on Growth,Immune, Antioxidant and Intestinal Microflora Structure of Black Carp (Mylopharyngodon piceus)北大核心CSCD

This experiment was conducted to study the effects of soybean meal replaced by fermented plant protein compound on growth, immune, antioxidant and intestinal microflora structure of black carp (Mylopharyn-godon piceus). The different proportions (1∶1 and 2∶1) of fermented cottonseed meal and fermented rapeseed meal were used to replace 0 (control group), 50% and 75% soybean meal in the basic diet, respectively, 5 kinds of isonitrogenous and isoenergetic experimental diets were prepared, and the black carp with initial weight of (6. 04 ± 0. 18) g were fed for 8 weeks. The results showed that there were no significant differences on growth performance, morphological indicators and body composition among all group (P>0.05). There were no significant differences on serum complement 3, malondialdehyde, albumin contents and lysozyme activity among all group (P>0.05). The serum complement 4 content in 50% replacement group was significantly higher than that in other groups (P<0.05), and the serum immunoglobulin M content in 75% replacement group was significantly higher than that in the control group (P<0.05). There were no significant differences on hepatopancreas superoxide dismutase, catalase, alkaline phosphatase activities and total antioxidant capacity and total cholesterol content among all group (P>0.05). There were no significant differences on intestinal α-amylase and lipase activities among all group (P>0.05), and the intestinal pepsin activity in fermented cottonseed meal and fermented rapeseed meal replacing 75% soybean meal with 1 ∶ 1 proportion group was significantly higher than that in the control group (P<0.05). The dominant microflora in intestine of black carp at the phylum level were Proteobacteria, Firmicutes, Fusobacteria and Planctomycotes, and the dominant bacteria at the genus level were Aeromonas, Cetobacterium, Ralstonia and Plesiomonas. There were no significant differences on the relative abundances of intestinal main microflora among all group (P>0.05). To sum up, under the experimental conditions, the high proportion (75%) of fermented plant protein replacing soybean meal do not cause hepatopancreas damage and intestinal microflora structure change of black carp, and even improve the activities of some immune indicators in serum and intestinal protease activity, and the compound proportion of fermented cottonseed meal and fermented rapeseed meal have no significant effects on growth performance, morphological indicators, body composition, hepatopancreas antioxidant indexes and intestinal microflora structure of black carp. © 2023 Chinese Journal of Urology.
