| 摘 要： | 【目的】通过分析牛乳中结合珠蛋白(HP)含量与其他乳成分之间的相关性,探讨HP能否作为评价乳品质的新指标。【方法】将5个月内所采集的30头荷斯坦奶牛150份乳样按乳汁体细胞计数(Somatic cell counnts,SCC)分成5组,分别测定各组乳样的脂肪、乳蛋白、乳糖、干物质、HP、K+、Ca2+、Mg2+、Na+和Cl-含量及过氧化酶(Lactoper-oxidase,LP)活性,并对HP含量与上述指标之间的相关性进行分析。【结果】HP含量与SCC及乳糖、干物质、脂肪、乳蛋白、无机盐离子含量和LP活性均存在不同程度的相关性;②SCC、LP活性和乳蛋白、Na+、Cl-含量均随HP含量的升高而增加,HP含量与SCC和LP活性呈显著正相关(P0.05);③乳糖、K+、Ca2+和Mg2+含量均随HP含量的升高而降低,HP含量与Ca2+、Mg2+含量呈显著负相关(P0.05),而脂肪和干物质含量在不同SCC组间差异不显著。【结论】牛乳中HP含量可间接反映出乳成分和牛乳品质的改变,可作为评价乳品质的一个候选指标。

| Abstract: | Objective] Through analyzing the correlation between the content of haptoglobin(HP)and the other raw milk composition,the study evaluated whether or not HP can be used as an indictor of raw milk compositional quality.Method] A total of 150 milk samples were divided into 5 groups by somatic cell counts(SCC)which were collected from 30 lactating Holstein cows in a dairy farm within five months.The contents of fat,lactoprotein,lactose,dry matter,HP,K+,Ca2+,Mg2+,Na+,Cl-and activity of LP were determined.Resu... |
