摘要:

本试验旨在对喷雾干燥鸡血浆蛋白粉在仔猪上的营养价值进行评定。试验采用单因子设计,将24头健康的“杜×长×大”三元杂交去势公猪(初始体重(24.96±1.05)kg)随机分配到3个处理,每个处理8个重复。分别饲喂无氮饲粮、玉米-豆粕型基础饲粮、鸡血浆蛋白粉饲粮(等氮替代基础饲粮中40%的氮)。所有仔猪预饲6 d后,进行4 d的消化代谢试验,收集全部粪尿,用于测定养分消化率和利用率。试验结束后所有仔猪麻醉屠宰,采集回肠末端食糜,用于测定氨基酸表观回肠消化率和标准回肠消化率。结果表明:喷雾干燥鸡血浆蛋白粉的粗蛋白质高达69.36%,赖氨酸含量为4.53%,蛋氨酸含量为1.65%,赖氨酸∶蛋氨酸∶色氨酸∶苏氨酸=100∶36∶30∶91,与猪的理想蛋白质氨基酸模式较接近;鸡血浆蛋白粉的表观消化能为16.02 MJ•kg-1,表观代谢能为15.39 MJ•kg-1;粗蛋白质的表观消化率和真消化率分别为87.58%和91.11%;除了甘氨酸外,所有氨基酸的标准回肠消化率都高于80%。综上表明,喷雾干燥鸡血浆蛋白粉是一种优质的动物性蛋白质原料。

Abstract:

The study was conducted to evaluate the nutritional value of spray-dried chicken plasma (SDCP) in piglets.A single factor design was adopted in this experiment.A total of 24 healthy crossbred “Duroc × Landrace × Yorkshire” barrows with an initial body weight of (24.96±1.05) kg were randomly allotted into 3 dietary treatments with 8 replicates per treatment.The 3 diets were N-free diet,corn-soybean basal diet and SDCP-diet (40% protein of basal diet were substituted by SDCP).After 6 days adaptation,all feces and urine from 24 piglets were collected for 4 days to determine the nutrient digestibility and availability.When the experiment ended,all piglets were euthanized and slaughtered to collect ileal digesta for determining apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids.The results showed that crude protein content of SDCP reached up to 69.36%,lysine content was 4.53%,methionine content was 1.65%,and lysine∶methionine∶tryptophan∶threonine=100∶36∶30∶91,which closed to the ideal protein animo acids model in pig.The apparent digestibility energy of SDCP was 16.02 MJ•kg-1,and the apparent metabolizable energy was 15.39 MJ•kg-1;apparent and true digestibility of crude protein were 87.58% and 91.11%,respectively;standardized ileal digestibility of all amino acids other than glycine were higher than 80%.Overall,spray-dried chicken plasma is a superior animal protein resource.
