菜籽粕(CM)是全球猪饲料生产中排行第二的蛋白原料,但菜籽粕营养成分变化大可能影响猪生产性能。为此,开展本次试验,353只断奶(断奶日龄19±1天)预饲2周,从中挑选体重、日增重相近的杜长大仔猪240只(起始体重9.6±0.7kg)随机分成5个处理... 详细信息

菜籽粕(CM)是全球猪饲料生产中排行第二的蛋白原料,但菜籽粕营养成分变化大可能影响猪生产性能。为此,开展本次试验,353只断奶(断奶日龄19±1天)预饲2周,从中挑选体重、日增重相近的杜长大仔猪240只(起始体重9.6±0.7kg)随机分成5个处理组,对照组饲喂大麦豆粕型基础饲粮,4个处理组分别饲喂来自加拿大北方三省的4种菜籽粕(分别等量替代200g/kg豆粕)饲粮,每个处理12个重复,每个重复4只,试验期4周,每周称重一次,并计算耗料情况。试验饲粮经蒸汽制粒,含粗蛋白质363~419g/kg,酸性洗涤纤维158~195g/kg,总硫代葡萄糖苷1.13~7.38μmol/g,代谢能9.6MJ/kg及1.2g SID Lys/MJ·NE。与对照组相比,菜籽粕组干物质(DM)、总能(GE)、粗蛋白质(CP)表观总消化率分别降低0.037、0.036和0.040(P<0.001),而菜籽粕组消化能(DE)变化不显著,净能(NE)提高0.078 MJ/kg(P=0.027)。四个菜粕组间DM、GE和CP的表观总消化率无显著差异,但DE与NE差异显著(P<0.01)。每周及实验全期日均采食量(ADFI)与日增重(ADG)各处理组间差异不显著,但1-7天与试验全期菜籽粕组增重耗料比高于对照组(P<0.05)。四个菜籽粕组间ADFI与ADG差异显著(P<0.05)。结论,200g/kg菜籽粕替代等量豆粕,不影响断奶仔猪ADFI与ADG,而菜籽粕间ADFI与ADG有差异,说明不同产地菜籽粕的品质差异将影响猪的生产性能。

本试验旨在确定最佳拟合膳食纤维组成,以评估膳食纤维(DF)水平对能量、粗纤维和氨基酸消化率的影响。9种玉米副产物分别为:玉米皮(37.0%总非淀粉多糖[NSP]);玉米皮可溶物(17.1%NSP);玉米干酒糟及可溶物(DDGS;20.4%NSP);脱脂DDGS(25.0%NSP);未煮过的DDGS(22.0%NSP);高蛋白干酒糟(21.9%NSP);脱壳,脱胚玉米(1.1%NSP);玉米胚芽粕(44.4%NSP);和玉米蛋白粉(4.9%NSP)。试验选用初始体重为(25.9±2.5)kg、回肠末端装有t型瘘管生长猪20头,随机分配给10种日粮处理,每个处理8个重复。玉米-豆粕基础日粮为对照日粮,70%基础日粮+30%评估原料组成9种试验日粮。评估原料中11种膳食纤维成分是酸性洗涤纤维(ADF),中性洗涤纤维(NDF),总日粮纤维,半纤维素,总非淀粉多糖,NSP阿拉伯糖,NSP木糖,NSP甘露糖,NSP葡聚糖,NSP半乳糖,阿拉伯木聚糖。测定原料中总能(GE),干物质(DM),NDF的表观回肠消化率(AID)、表观全肠道消化率(AttD),并测定氨基酸的AID。对每种原料种最佳纤维组分进行评估并排序,结果显示:阿拉伯木聚糖含量与GE(r^2=0.65;三次曲线,Pr^2=0.67;三次曲线,Pr^2=0.80;三次曲线,Pr^2=0.78三次曲线,Pr^2=0.63;三次曲线,PttD呈正相关;与蛋氨酸(r^2=0.40;三次曲线,P=0.02),蛋氨酸+半胱氨酸(r^2=0.44;三次曲线,P=0.04)和色氨酸(r2=0.11;三次曲线,P=0.04)的AID呈正相关;与DE(r2=0.66;线性,P=0.02)和ME(r2=0.71;三次曲线,P=0.01)呈正相关。DF含量无法预测赖氨酸的AID(P>0.05)。结论,阿拉伯木聚糖和NSP木糖残基可以解释由于日粮纤维水平改变引起的变化,可用于预测玉米副产物中除赖氨酸AID以外的纤维能量消化率,以及消化能和代谢能。

A patient with pseudomyxoma peritonei underwent Hyperthermal Intraperitoneal Chemotherapy (HIPEC) with Mitomycin C after which she developed thrombotic microangiopathy. this syndrome mimicked possi-ble surgical complications. treatment with plasma exchange resolved the syndrome and the patient recov-ered completely. this is the first description of thrombotic microangiopathy early after a single dose intrap-eritoneal Mitomycin C.
