关键制粒工艺参数对颗粒饲料质量及猪生长性能的影响研究进展OA

Pelletizing feed plays a crucial role in pig production,primarily by enhancing the physical stability and nutritional balance of the feed,improving palatability and digestibility,thereby increasing feed conversion efficiency and promoting healthy growth in pigs.In addition to the decisive impact of raw material type and properties on pellet feed quality,processing parameters,equipment structure,and operational methods also play key roles in determining pellet quality.Therefore,effective control of pellet feed quality requires an integrated approach that considers raw material characteristics,processing parameters,and equipment factors.While significant progress has been made in domestic and international research on the effects of pelletizing processes on feed quality and animal growth performance,systematic analyses of how different pelletizing processes affect feed quality and pig growth performance are still relatively scarce.This review article summarizes relevant studies and explores the effects of key processing parameters,such as grinding particle size,conditioning temperature,and conditioning time,influence pellet hardness,durability,and starch gelatinization,providing a theoretical basis for improving pellet feed processing efficiency and pig growth performance.
