几种棉粕饲料的质量评定

试验旨在研究棉粕感官鉴定结果同其营养成分化学检验结果的相关性,为生产中感官检测提供理论依据。采集市面上不同产地及不同厂家的6种棉粕,测定其所含粗蛋白、游离棉酚、NDF、ADF、ADL的量。结果表明,6种棉粕所含游离棉酚量都在国标允许范围内,并且棉粕的色泽与游离棉酚含量有一定的相关性。试验数据表明,黄色棉粕较发红的棉粕游离棉酚含量高。棉壳含量是影响棉粕粗蛋白高低的主要因素,两者呈明显的负相关。棉壳和棉絮含量与纤维呈正相关,棉壳和棉絮含量过高则会影响到棉粕的品质。

Quality Assessment of Several Kinds of Cottonseed Meal Feed

The research aimed to study the correlation between the sensory evaluation results of cottonseed meal and the chemical test results of its nutritional components and provide theoretical basis for the sensory detection in the production.Six kinds of cottonseed meal from different factories of different areas were collected to determine the contents of crude protein,free gossypol,NDF,ADF,ADL.The results showed that the content of free gossypol in six kinds of cottonseed meal was below the international allowable range and the colour and luster of cottonseed meal had certain correlation with the content of free gossypol.The test results showed that red cottonseed meal had higher content of free gossypol.The content of cotton hull was the main cause that affected the content of crude protein in cottonseed meal,showing an obvious negative correlation.The content of cotton hull and cotton wool showed a positive correlation with the fiber content.Too higher content of cotton hull and cotton wool would affect the quality of cottonseed meal.
