为了揭示特种野猪消化生理特征，文章以三元杂交猪为对照，测定了体重50 kg特种野猪的消化道结构及其对饲料主要养分的消化力。结果表明，特种野猪消化道各部位的重量、长度和容积均小（短）于相似体重的三元杂交猪。特种野猪对饲料干物质消化率（81.30%）、粗蛋白质消化率（79.01%）、能量消化率（82.84%）、钙消化率（36.92%）和磷消化率（49.93%）显著高于三元杂交猪（P<0.05）。特种野猪采食量小，仅为三元杂交猪的71.87%，特种野猪对饲料干物质、粗蛋白质、能量、粗脂肪、粗纤维、钙和磷的消化量均低于三元杂交猪，这可能是特种野猪生长速度缓慢的主要原因之一。
為瞭揭示特種野豬消化生理特徵，文章以三元雜交豬為對照，測定瞭體重50 kg特種野豬的消化道結構及其對飼料主要養分的消化力。結果錶明，特種野豬消化道各部位的重量、長度和容積均小（短）于相似體重的三元雜交豬。特種野豬對飼料榦物質消化率（81.30%）、粗蛋白質消化率（79.01%）、能量消化率（82.84%）、鈣消化率（36.92%）和燐消化率（49.93%）顯著高于三元雜交豬（P<0.05）。特種野豬採食量小，僅為三元雜交豬的71.87%，特種野豬對飼料榦物質、粗蛋白質、能量、粗脂肪、粗纖維、鈣和燐的消化量均低于三元雜交豬，這可能是特種野豬生長速度緩慢的主要原因之一。

In this article, digestive tract structure and digestive ability of special wild boars weighting 50 kg were measured, compared with that of three-breed cross pigs. The result showed that the weight, length and volume of the every parts of digestive tract of special wild boars were smaller (shorter) than that of three-breed cross pigs. Digestibility of dry matter, crude protein, energy, calcium and phosphorous of special wild boars were 81.30%, 79.01%, 82.84%, 36.92% and 49.93% respectively, which were significantly higher than that of three-breed cross pigs. The average daily feed intake(ADFI) of special wild boars were only 71.87 per-cent of the ADG of three-breed cross pigs, and the dry matter, crude protein, energy, ether ex-tract, crude fiber, calcium and phosphorous digestion amount were lower than that of three-breed cross pigs, which may be one of the primary cause of special wild boars' slow growth.
