【摘要】 鱼粉和肉骨粉是重要的饲料原料，其品质优劣直接影响畜牧业生产和人民身体健康。目前常用检验方法十分繁琐费时，品质检测工作量相当大，随着养殖业的快速发展，如何保证饲料质量和提高检测速度已成为新的重要课题之一。本文选用饲料领域处于探索阶段的近红外透射(NIT)技术对鱼粉和肉骨粉的品质检测进行研究。随机选鱼粉样品199个、肉骨粉149个，用常规法检测其蛋白质、脂肪含量，再用NIT法分析，包括定标、建模和验证、预测实验等；数据处理用WinISI软件完成。结果表明：1)NIT法可以对动物性饲料如肉骨粉的品质实现多成份、快速的检测。其蛋白质、脂肪定标标准偏差分别为1.67％和0.75％，定标相关系数分别为0.84和0.93；验证标准偏差分别为1.81％和0.87％，验证相关系数分别为0.82和0.92；定标方程检验F值分别为13.94和12.36，有显著性意义(P＜0.01)。预测标准偏差分别为1.73％和0.64％，预测相关系数分别为0.83和0.95。2)鱼粉和肉骨粉的NIT光谱特性不同，有可能在测定成分含量的同时鉴定样品是鱼粉或是肉骨粉，这样可更好地鉴定饲料的品质和真伪。3)不是所有鱼粉都适合作NIT分析。初步认为来源于北冰洋的鱼粉NIT光谱特性稳定，而来源于南太平洋的鱼粉NIT光谱特性不稳定。NIT法在鱼粉品质快速检测中的运用有待进一步探讨。更多还原

【Abstract】 Fishmeal (FM) and meat & bone meal (MBM) are important materials of feed. Good or bad of their qualities influence greatly on the production of stock raising and people’s healthy. The inspecting methods are of complication, and take a lot of time at present. The workload of the quality inspection is very big. As the booming development of breed aquatics industry, how to guarantee the quality of feed and to increase the speed of inspection has become one of the new important subjects. The near infrared transmittance quantitative analysis technique (NTT), which is preceding in the feed field, was used in the study on the quality inspection of FM and MBM. 149 FM and 199 MBM samples were chosen randomly. Routine inspecting methods and NIT were applied to inspect their qualities of protein and fat respectively. The study included calibrating, model making, validating and predicting. Data were managed and analyzed by WinlSI. Results indicate: 1) NTT can simply, quickly inspect several components of the qualities of animal feed such as MBM at one time. The standard errors (SEs) of calibration of protein and fat were 1.67% and 0.75% respectively. Relative coefficients (Rs) of verification calibration were 0.84 and 0.93 respectively. The SEs of verification were 1.81% and 0.87% respectively, and Rs of were 0.82 and 0.92 respectively. The tests of calibrating models of protein and fat were significant, all PO.01. F values were: 13.94 and 12.36 respectively. The SEs of prediction were 1.73% and 0.64% respectively, and the Rs of prediction were 0.83 and 0.95 respectively. 2) There are some differences in the characteristics of NIT spectrograms between FM and MBM. This makes it possible to judge whether it is FM or MBM while inspecting their component contents. So, true or false of animal feed quality can be better judged.3) Not all kinds of FM can be suitably inspected by NTT. The preliminary conclusion is that FM which comes from the Arctic Ocean has stable NIT spectrograms, but the one which comes from the South Pacific Ocean has the opposite.. The use of NIT in FM needs further study.更多还原
