【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6d后,进行4d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15.39MJ·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 purpose of this study was to assess the nutritional value of spray dried chicken plasma protein powder in piglets. The test uses a single factor design, 24 healthy Duroc * Landrace * large three crossbred castrated boars (initial body weight (24.96 + 1.05) kg) were randomly assigned to 3 treatments with 8 replicates respectively. Feeding nitrogen free diet, corn soybean based diet, chicken plasma protein powder diet (DLRM based diet of 40% nitrogen). All piglets pre feeding 6D, digestion and metabolism experiment 4D, collect all urine, for the determination of nutrient digestibility and utilization. At the end of the experiment, all piglets were anesthetized slaughter, collection of ileal digesta, for the determination of amino acid apparent ileal digestibility and standardized ileal digestibility. The results showed that the crude protein of chicken plasma protein powder spray drying up to 69.36%, the content of lysine was 4.53%, methionine content 1.65%, lysine, methionine Acid, tryptophan, threonine =100: 36: 30: 91, is close to the ideal protein amino acid pattern of pig chicken plasma protein powder; apparent digestible energy was 16.02 MJ - kg-1, apparent metabolic energy is 15.39MJ - kg-1; crude protein apparent digestibility and true digestibility were 87.58% and 91.11%; in addition to glycine, standard ileal digestion of all amino acids were all higher than 80%. in conclusion, spray dried chicken plasma protein powder is a kind of high-quality animal protein materials.
