Estimation of Digestible Energy Values of Plant Protein Supplement in Pig
[Objective] The aim of the study was to establish the effective and accurate formulas for estimating the digestible energy (DE) values of plant protein supplement in pig. [Method] By difference method with different amount of alternative feeds (20%-50%), two 4×4 Latin-square-designed trials were taken on eight castrated male pigs [Yorkshire×Landrace×Neijiang pig, initial body-weight: (46±2) kg] to determine the apparent digestible energy (ADE) of the eight kinds of plant protein supplement commonly used in China, that is, corn gluten meal (sol.), soybean meal (sol.), fababean, pea, rapeseed meal (sol.), sesame meal (sol.), rapeseed meal(exp.) and cotton seed meal (sol.). [Result] (1) Fiber was the most important factor to estimate the ADE of plant protein supplement in pigs, and ADF was the best one. (2) The most effective equations were as below: (1) DE (kJ/kg DM) =14 741.86-185.01ADF+54.01SCHO+22.45CP (R2=0.988,RSD=67.9,P<0.01); (2) DE (kJ/kg DM) =22 223.26-209.58ADF+26.79SCHO-1.09GE (R2=0.989,RSD=66.9,P<0.01).[Conclusion] The accurate, practical and specific regression equations were established for DE prediction of plant protein supplement in pig.
