Abstract

The effect of ketone bodies on crop emptying was studied in chickens in 2 experiments. In the first, the effect of beta-hydroxybutyrate, acetoacetate or acetone on relative crop content was measured. The effects of dietary medium and long chain triacylglycerols upon serum beta-hydroxybutyrate were investigated in the second. 2. beta-Hydroxybutyrate, but not acetoacetate and acetone, delayed crop emptying in a dose dependent fashion. Serum beta-hydroxybutyrate concentration was high in chicks given medium chain triacylglycerol, when compared with long chain triacylglycerol. 3. The results suggest that delayed crop emptying induced by medium chain triacylglycerol could partly be explained by an enhanced concentration of serum beta-hydroxybutyrate, which is the result of the rapid oxidation of medium chain fatty acids.

摘要

在两项实验中研究了酮体对鸡嗉囊排空的影响。在第一项实验中，测定了β-羟基丁酸、乙酰乙酸或丙酮对嗉囊相对内容物的影响。在第二项实验中，研究了日粮中链和长链三酰甘油对血清β-羟基丁酸的影响。2. β-羟基丁酸而非乙酰乙酸和丙酮以剂量依赖方式延迟嗉囊排空。与长链三酰甘油相比，给予中链三酰甘油的雏鸡血清β-羟基丁酸浓度较高。3. 结果表明，中链三酰甘油诱导的嗉囊排空延迟部分可由血清β-羟基丁酸浓度升高来解释，这是中链脂肪酸快速氧化的结果。
