摘要
日粮纤维为结构性与非结构性多糖和木质素的总称。猪对日粮纤维的消化随日粮纤维来源和组分不同而存在差异。随体重和年龄的增加,猪对日粮纤维消化能力提高,成年母猪对日粮纤维利用率最高。对高日粮纤维饲料至少要提供2个能量值:一个对生长猪,一个对成年母猪。日粮纤维对猪能量供应的实际效果受到环境温度或动物行为变化的影响。
Dietary fibre (DF) is defined as the sum of structural and non-structural polysaccharides and lignin. DF has a large variation in digestibility coefficient for its different source and composition. Digestibility coefficient of DF improves with body weight and age of the pig with the highest values obtained in adult sows. It is therefore recommended to give at least two energy values for dietary ingredient with high DF in pig feeds: one for growing pigs and one for adult sows. The actual contribution of dietary fibre to energy balance of the pig can be affected by climatic condition or behavior of pigs.
