【摘要】 试验选取6只内蒙古细毛羊健康泌乳母羊，分别于泌乳前期（Ⅰ、Ⅱ期）、泌乳中期（Ⅲ期）和泌乳后期（Ⅳ期），采用消化代谢、气体能量代谢等试验方法，运用灰色关联度分析法，探讨放牧条件下主要气候因素（气温、气湿、风速）对母羊不同泌乳期营养物质消化代谢的影响。结果表明，在本试验条件下，试验羊产热量受风速影响最大，机体能量存留量受气温影响最明显，而来食量、消化率、N存留量及总能代谢率等项指标与空气湿度关系最密切。更多还原

【Abstract】 The experiment was divided into four periods:Previous lactation (Period Ⅰand Ⅱ), middle lactation (Period Ⅲ) and later lactation (Period Ⅳ ). During each period,digestion and metabolism test and gas energy metabolic test were carried out. Air temperature,relative humidity and wind velocity were measured, A grey system analysis was used. The results showed that effects of different climatic factors on digestion and metabolism were different.更多还原
