Twenty-three mature dwarf goats were used to study whether there is a relationship between the decrease in feed intake for individual goats and infection with T.congolense and T. vivax. Furthermore, it was investigated how rectal temperatures and blood parameters were affected by the T. congolense infection and how changes in these parameters can be used to predict the effect of a T. vivax infection on feed intake. For individual goats a ranking correlation was found between relative dry matter intake and infection (r = 0.59; p < .05). Animals with the most marked decrease in dry matter intake during the T. congolense infection showed a smaller increase in urea and a higher increase in non esterified fatty acids and beta-hydroxy butyrate levels in their blood. Evidence was obtained that the relative decrease in dry matter intake for individual goats during a T. vivax infection can be predicted on the basis of urea and creatinine responses measured in the blood during a previous infection with T. congolense infection.
选用23只成年矮山羊来研究个体山羊采食量的减少与感染刚果锥虫和活泼锥虫之间是否存在关联。此外，还研究了刚果锥虫感染如何影响直肠温度和血液参数，以及这些参数的变化如何用于预测活泼锥虫感染对采食量的影响。对于个体山羊，发现相对干物质摄入量与感染之间存在等级相关性（r = 0.59；p <.05）。在感染刚果锥虫期间干物质摄入量下降最明显的动物，其血液中尿素的增加幅度较小，非酯化脂肪酸和β-羟基丁酸水平的增加幅度较大。有证据表明，根据先前感染刚果锥虫期间血液中测量的尿素和肌酐反应，可以预测个体山羊在感染活泼锥虫期间干物质摄入量的相对下降情况。
