摘要
[目的]系统评估浙江省地源性蛋白质饲料资源的营养成分特征,为建立浙江省地源性蛋白质资源数据库、豆粕减量替代行动及饲料产业优化积累数据。[方法]采集14种浙江省地源性蛋白质饲料原料,通过测定粗蛋白、粗纤维和氨基酸等营养成分,结合方差分析与相关性统计,分析资源特征。[结果]粗蛋白含量:米糠粉最低[(5.69±1.82)%],羽毛粉最高[(81.48±4.36)%],脱脂米糠中等[(14.61±1.15)%];粗纤维含量:鱼粉最低[(2.70±1.28)%],米糠粉最高[(26.97±15.14)%],脱脂米糠中等[(8.91±0.66)%],脱脂米糠粗纤维含量与米糠粉和花生粕差异显著(P<0.05);氨基酸总量:米糠粉最低[(4.38±1.74)%],羽毛粉最高[(77.03±3.80)%],脱脂米糠中等[(11.86±1.06)%],脱脂米糠氨基酸总量与酒糟、米糠粉、小麦麸的差异不显著(P>0.05),与其他品种差异显著(P<0.05)。粗蛋白含量与粗纤维含量存在极显著(P<0.01)的负相关关系,表明蛋白质含量较高的饲料原料,通常纤维含量较低;粗蛋白含量与氨基酸总量存在极显著(P<0.01)的正相关关系,表明蛋白质含量高的饲料原料,氨基酸含量也较高。粗纤维含量与氨基酸总量之间存在极显著(P<0.01)的负相关关系,与粗灰分之间存在显著(P<0.05)的负相关关系。粗灰分含量与水分含量之间存在显著(P<0.05)的负相关关系。[结论]脱脂米糠为浙江省丰富的地源性蛋白质饲料资源,在应用中需考虑其较高的纤维素含量对动物消化率的影响。后续通过发酵、菌酶协同技术和低温加工工艺等技术创新,脱脂米糠的营养缺陷有望得到突破,具有巨大的开发潜力和应用前景。
[Objective]To systematically assess the nutrient composition characteristics of ground source protein feed resources in Zhejiang Province,and to accumulate data for the establishment of a database of ground source protein resources,soybean meal reduction and substitution actions and feed industry optimization in Zhejiang Province.[Methods]Fourteen kinds of ground source protein feedstuffs from Zhejiang Province were collected,and the resource characteristics were analyzed by determining the nutrient compositions of crude protein,crude fiber,and amino acid,combined with the analysis of variance(ANOVA)and correlation statistics.[Results]Crude protein content:rice bran meal was the lowest[(5.69±1.82)%],feather meal was the highest[(81.48±4.36)%],and defatted rice bran was the medium[(14.61±1.15)%];crude fiber content:fish meal was the lowest[(2.70±1.28)%],rice bran meal was the highest[(26.97±15.14)%],and defatted rice bran was the medium[(8.91±0.66)%].The crude fiber content of defatted rice bran showed significant difference(P<0.05)with rice bran meal and peanut meal;total amino acids content:rice bran meal was the lowest[(4.38±1.74)%],feather meal was the highest[(77.03±3.80)%],and defatted rice bran was medium[(11.86±1.06)%],and the total amino acid content of defatted rice bran was not significantly different(P>0.05)with wine lees,rice bran meal and wheat bran,and the difference with other varieties was significant(P<0.05).There was a highly significant(P<0.01)negative correlation between crude protein content and crude fiber content,indicating that feedstuffs with higher protein content usually have lower fiber content;there was a highly significant(P<0.01)positive correlation between crude protein content and total amino acid content,indicating that feedstuffs with higher protein content contain higher amino acids.There was a highly significant(P<0.01)negative correlationbetween crude fiber content and total amino acids content,and a significant(P<0.05)negative correlation between crude fiber content and crude ash content.There was a significant(P<0.05)negative correlation between crude ash content and moisture content.[Conclusion]Defatted rice bran is an abundant ground source protein feed resource in Zhejiang Province.The effect of its high cellulose content on animal digestibility should be considered in application.Subsequently,through technological innovations such as fermentation technology,bacteria-enzyme synergy technology and low-temperature processing technology,the nutritional deficiencies of defatted rice bran are expected to be broken through,which has great development potential and application prospects.
