【摘要】 本试验通过对血红蛋白制取方法的筛选，选择最经济、最简单的方法制得血红蛋白粉，并进行粗蛋白和氨基酸分析与国产鱼粉相对比。通过断奶仔猪(35日龄)的饲养试验、消化试验和血液指标分析，研究了血红蛋白粉对断奶仔猪生产性能和免疫机能的影响。试验结果表明： 1、血红蛋白粉是一种粗蛋白含量达91％的动物性蛋白源，且含有丰富的血红素铁。含有高的赖氨酸，但异亮氨酸缺乏。 2、经过用不同方法处理猪血球得到血红蛋白粉的筛选，从经济效益和大批量生产的角度出发选择用自来水作为破膜液是最适合规模化生产的。 3、通过消化试验证明，试验组与对照组之间除了铁的消化率外，其它营养物质的消化率没有显著性差异，但铁的消化率随血红蛋白粉添加量的增加而升高。 4、通过饲养试验表明，添加3％血红蛋白粉组仔猪的发病率(包括气喘病和腹泻病)和死亡率最低。并且添加3％血红蛋白粉组仔猪的生产性能也最高。 5、从血液指标分析来看，试验组与对照组仔猪的部分血液指标存在显著差异。转铁蛋白、IgG、血浆铁含量、血红蛋白含量都随血红蛋白粉添加量的增加而上升；血浆尿素氮随血红蛋白粉添加量的增加而降低；只有血糖浓度没有显著性差异。更多还原

【Abstract】 Hemoglobin powder was extracted by the most economic and at the same time the simplest method. The concentration of protein and amino acids were analyzed and compared with that of domestic fish meal. Feeding experiment, digestion as well as analysis of blood indices were conducted to investigate the effect of hemoglobin powder on performance and immunity function of weeding piglets on 35 days. The results are as follows:1. Hemoglobin powder is a kind of animal quality protein feed, containing 91% of CP, plentiful hemochrome iron, high lysine but low isoleucine.2. From the point of economic efficiency and mass production, the best breaking-cellular membrane liquid of hemoglobin powder is running water.3. Digestion trial indicates that the digestibility of nutrients are not significantly different between control group and treatment group. Except for that of iron which increases when adding more hemoglobin powder in the diet.4. Feeding experiment shows that disease incidence (including asthma and diarrhea)and death rate of weeding piglets sre the lowest when adding 3% hemoglobin powder in the diet. And the grain weights of piglet are the best in the group adding 3% of hemoglobin powder.5. According to analysis of blood indices. Transferion, IgG. Plasma iron. Hemoglobin levels increase significantly while PUN concentration decreases apparently in treatment group, only blood sugar concentration remains no different.更多还原
