陕西地区水产饲料质量分析与评估

Analysis and Evaluation of Aquatic Feeds Quality in Shaanxi Province

在陕西省饲料企业和水产养殖场随机抽取19种鲤草鱼饲料样品,对其物理性状和营养成分进行检测,并依据水产饲料行业标准进行分析和评价。检测结果发现:(1)饲料物理性状均符合行业标准;(2)水分检测值均符合标签值和标准值,但偏低;(3)蛋白检测值与标签值的符合率为78.9%,与标准值的符合率为94.7%;(4)粗脂肪检测值均符合标签值,与标准值的符合率为73.7%;(5)粗纤维检测值与标签值的符合率为94.7%,与标准值的符合率73.7%;(6)粗灰分检测值与标签值的符合率为94.7%,与标准值的符合率为94.7%。说明陕西地区水产饲料质量情况基本良好,但仍存在重视蛋白水平、忽视水分和脂肪水平等问题,建议陕西省水产饲料企业重视养分均衡供应,进一步提高饲料质量。

19 common carp and grass carp feed were collected in Shaanxi province. The physical proper- ties and nutrition indices of the samples were tested according to the latest testing standards,and analyzed based on the latest industry standards. The physical properties were in line with the industry standards, all the moisture content detection values conformed with the label values and standard values, but the results showed that the moisture values of partial samples were lower than standard values. Coincidence rate of detection values and label values for protein content was 78.9%, while that for detection values and stand- ard values was 94.7%. The coincidence rate of crude fat content for detention values was 100% and 73.7% for standard values. Likewise,the conincidence rate of detented valves and label values for crude fiber was 94.7 %, that of standard values was 73.7% both of which for crude ash was 94.7 %. The results indicate that the aquafeeds in Shaanxi province are qualified, but the problems such as focusing on protein level but ignoring moisture and fat level still exist. It is proposed that the aquafeeds enterprises pay attention to the balanced nutrients of the feeds,and further improve the quality of feeds.
