摘要: 猪饲料的消化能(DE)是编制猪饲料营养价值表、制定猪饲养标准的重要指标。猪饲料种类繁多,若一一通过消化试验实测DE,不但工作量大,且因影响消化试验的因素很多,也难测得可靠的、有代表性的数据。为编制四川及南方猪饲养标准和饲料营养价值表,作者在研究国内外已有猪饲料或日粮消化试验资料基础上,提出了间接评定猪饲料DE的回归方程,并对四川及南方各类猪饲料共500多种进行了评定。

Abstract: Useing of path analysis and multivariate regression, relationship of CP.EE. CF、NFE with DE of Concentrate (CF<18%)、Plant protein supplement (CP≥20%)、Animal protein supplement (CP≥20%)、Dry Roughage (CF≥18%)、Roots, Tubers, Pumpkin etc. (Water≥60%) and Green forages (Water≥60%) are studied; multivariate regressionsre established to estimate digestible energy of pig feeds Estimated result is more accurate and reliable.
