The effect on ventriculus muscularis electric activities and gastric acid secretion of Beijing duck was observed by injection -enkephalin and naloxone to the third cerebral ventride.
本实验观察了第三脑室注射甲硫氨酸脑啡肽和阿片受体阻断剂纳洛酮对北京鸭肌胃电和胃酸分泌的影响,结果表明:脑室注射5μg、10μg、25μg脑啡肽,均可使北京鸭肌胃电平均每簇快波数和每分钟快波数,极显著低于注射前和注射生理盐水(P<0。
The relation between this SNP and chicken body composition traits (especially for the gizzard weight) were analyzed.
以中国农业大学明星肉鸡和丝羽乌骨鸡构建的资源家系F2代群体作为实验材料, 对鸡α-Ⅱ型角蛋白C基因(KIIC)进行SNP检测,探讨KIIC基因作为影响体组成性状(尤其是肌胃重)候选基因的可能性。
