摘要

本试验旨在确定羊驼第一胃室与绵羊瘤胃固相和液相外流速率。选用1周岁健康的公羊驼[(27.0±4.6) kg]与晋中公绵羊[(26.2±2.7) kg]各3只,通过钴(Co)和铬(Cr)双标记法测定固相和液相外流速率。结果显示,根据MC模型羊驼固相慢速外流速率k1(3.44%/h)有低于绵羊(4.32%/h)的趋势(P=0.072),固相快速外流速率k2,羊驼(16.90%/h)极显著低于绵羊(35.06%/h)(P<0.01);根据指数模型羊驼固相外流速率k(5.13%/h)与绵羊(5.14%/h)差异不显著(P>0.05);模型所得羊驼食糜胃肠道平均滞留时间高于绵羊。根据G4模型和指数模型,羊驼液相外流速率k(分别为6.21%/h和7.73%/h)与绵羊(分别为7.02%/h和8.43%/h)差异不显著(P>0.05),2种模型所得液相外流速率k差异不显著(P>0.05),但羊驼第一胃室容积(6.23 L)和外流速度(0.44 L/h)极显著低于绵羊瘤胃容积(10.69 L)和外流速度(0.90 L/h)(P<0.01)。结果提示,食糜在羊驼体内的消化时间长于绵羊,这可能是羊驼粗饲料消化率高的原因之一。

Abstract

This experiment was conducted to determine the outflow rate of solids and fluid using double markers of chromium (Cr) and cobalt (Co) from the first compartment in alpaca and rumen in sheep. Three healthy male alpacas [(27.0±4.6) kg] and Jinzhong sheep [(26.2±2.7) kg] were selected. The results showed as follows: estimated by multicompartmental model, in comparison to sheep, solid slow outflow rate k1 showed a decreasing tendency (3.44%/h vs. 4.32%/h, P=0.072) and solid fast outflow rate k2 was significantly lower in alpaca (16.90%/h vs. 35.06%/h, P<0.01). There was no significant difference to solid outflow rate k estimated by exponential model between alpaca (5.13%/h) and sheep (5.14%/h) (P>0.05). Mean residence time (MRT) of alpaca was higher than that of sheep in both models. Estimated by gamma 4 model and exponential model, no significant difference was recorded to fluid outflow rate k between alpaca (6.21%/h and 7.73%/h) and sheep (7.02%/h and 8.43%/h) (P>0.05). The volume (6.23 L) and out follow speed of the first compartment in alpaca(0.44 L/h) were significantly lower than those in sheep (10.69 L and 0.90 L/h) (P<0.05). In conclusion, gastrointestinal retention time of digesta in alpaca is longer than that in sheep, and the difference can partly explain the reason that alpaca has a higher roughage digestion rate.
