Abstract

Twenty adult West African dwarf (Fouta djallon) does about 2 yr old and weighing from 23 to 28 kg were kept for two 18-wk lactations. Blood samples were obtained once weekly from 2 to 18 wk of lactation except in the 1st wk after parturition when samples were every other day for chemical analysis. Blood serum from the 2nd to the 18th wk contained the following averages (mg/100 ml) with standard deviations: calcium 10.52, 1.47; phosphorus 7.43, 1.0; magnesium 2.99, .42; (meq/liter) sodium 140.10, 3.83; and potassium 4.9, .45. In blood during the 1st wk after parturition they were 8.46, .40; 6.05, .12; 3.74, .12; 147.72, .63; and 6.28, .25. Trends increased with advance in lactation except for magnesium and potassium, which decreased.

摘要

二十只成年西非矮种（富塔贾隆）母羊，年龄约2岁，体重23至28千克，进行了两次为期18周的泌乳期实验。在泌乳期的第2周（产后第1周除外）至第18周每周采集一次血样，产后第1周每隔一天采集血样用于化学分析。第2周（产后第1周除外）至第18周的血清中各物质平均含量（毫克/100毫升）及标准差如下：钙10.52，1.47；磷7.43，1.0；镁2.99，0.42；（毫当量/升）钠140.10，3.83；钾4.9，0.45。产后第1周血液中各物质含量分别为：钙8.46，0.40；磷6.05，0.12；镁3.74，0.12；钠147.72，0.63；钾6.28，0.25。除镁和钾含量下降外，其他物质含量随泌乳期推进呈上升趋势。
