%X 本试验通过对哈萨克绵羊外源性添加L-肉碱(左旋肉碱)，观察哈萨克绵羊发情行为变化，分析添加L-肉碱对哈萨克绵羊激素的影响，试验选用16只1周岁哈萨克绵羊，将试验羊群随机分成2组：实验组与对照组，每组8只哈萨克绵羊(1岁)。实验组在精料(200 g)中添加肉碱(每只羊75 mg/kg)，对照组只饲喂精料(200 g)，每天采集血样并分离血清保存，测定激素变化。结果表明：饲料中添加的L-肉碱间接地影响了绵羊体内MLT (褪黑素)；E2 (雌二醇)；FSH (促卵泡素)；LH (促黄体生成素)；P4 (孕激素)的分泌量并在绵羊繁殖方面产生了重要影响。<br />
In this experiment, by exogenously adding L-carnitine to Kazakh sheep, we observed the estrus behavior change of Kazakh sheep and analyzed the impact of added L-carnitine on hormones of Kazakh sheep. 16 Kazakh sheep were selected and randomly divided into two groups: experimental group and control group, which consisted of eight Kazakh sheep (1 year old), respectively. The sheep in experimental group fed on concentrate (200 g) that added L-carnitine (each sheep 75 mg/kg), the rest in control group fed only on concentrate (200 g). Blood samples were collected every day and stored serum, measured hormonal changes. The results show L-car- nitine dietary indirectly affects the MLT; E2; FSH; LH; P4 secretion of sheep and has an important impact on sheep breeding.
