摘要
针对当前大多数禁牧、休牧区柠条(Caragana korshinskii)资源储量大但利用率低的现状,寻找能有效降低纤维类物质含量、改善适口性、提高饲用价值的利用途径,成为柠条饲料化研究的重点。本试验将有效降低木质素和纤维素含量的膨化技术应用于柠条的保护性开发利用中,对柠条的营养成分进行分析,进而对其饲用膨化技术和营养价值进行评价探讨。结果表明,在压力1.0 MPa、温度170℃、原料含水量30%、切短长度2 cm的条件下,膨化效果最好,柠条中木质素含量最低,干质量消化率最大。
It is important to seek an approach to effectively reduce the fiber content and improve palatability and the forage value of Caragana korshinskii for improving the current utilization status of C. korshinskii growing at the forbidden grazing and rest-grazing areas. The puffed technique was used to effectively reduce the lignin and cellulose content of C. korshinskii in this study by comparing the nutrients of C. korshinskii. The atmospheric pressure, temperature, the moisture content of raw material, and the cut length were applied to optimize the processing techniques of puffed C. korshinskii in this experiment. The results of this study showed that the 1.0 MPa atmospheric pressure, 170℃ temperature, 30% of the moisture content of raw material, 2 cm the lengths was optimal conditions for the puffing C. korshinskii, in which the ADL content of C. korshinskii was the lowest and the digestibility of C. korshinskii was largest.
