特种野猪的消化道结构与消化力测定

Measurement on digestive tract structure and digestive ability of special wild boars

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。

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.
