Hens maintaining broodiness even after being treated with drugs had PRL and LH levels similar to those of controls.

药物处理后仍未终止就巢鸡的血浆PRL和LH水平都与对照组的类似。

In avian, PRL is especially crucial for reproduction traits such as broodiness and thus for egg production.

在家禽中PRL主要影响就巢性，进而影响到产蛋性能等繁殖性状。

Considering the biological importance of POU1F1 and the results got in our research, we suggested that Pit-1 be a candidate gene for growth, egg laying and broodiness research in poultry.

考虑到POU1F1的重要作用和作者的研究，作者认为Pit-1基因可作为家禽生长、产蛋、就巢性等重要经济性状的候选基因。

Blood LH concentrations of these hens gradually increased from initial value of less than 1 ng／ml on day 2 to values about 3.0 ng／ml on day 19 after onset of broodiness.

对照组在持续就巢期间的血浆LH水平低于1.0 ng／ml，而用药后终止就巢鸡的血浆LH水平从处理前的小于1.0 ng／ml逐渐上升至第19天的3.0 ng／ml左右。

In seven out of 9,and 6 out of 13 hens treated with chlorpromazine or cyproheptadine terminated broodiness following drug treatment,blood PRL levels all decreased from high levels on day 2 of broodiness to levels below 20 ng／ml on day 4 and maintained at low levels to day 19 after onset of broodiness.

试验2：7只就巢鸡在就巢的第2、4、9、14和19 d血浆PRL水平维持在200～400 ng／ml之间；9只氯丙嗪处理后终止就巢的7只鸡以及13只赛更啶处理后终止就巢的6只鸡，血浆PRL由就巢第2 d与对照组类似的高水平急剧下降到第4 d小于20 ng／ml，并至第19 d一直处于较低水平。

For female chickens, however, the body weight at 14 wks of age for AA was greater (p.05) than that for TT. Therefore, P0U1F1_6 is an effective molecular marker that can be used in MAS program for early growth rate in chicken, especially for male chickens.The better understanding of the mechanism of broodiness stands great significance not only for avian genetics, behavior, and endocrinology, but also for the acceleration of poultry breeding progress against broodiness to enhance egg producti

研究家禽就巢性的遗传机理，不但对鸟类遗传学、行为学、内分泌学等方面有重要的理论意义，而且本研究成果有助于加速无就巢性或低就巢性的家禽品种或品系的培育，从而提高禽群的产蛋性能和种刚性能，尤其对我国地方禽种资源的开发利用有重要的意义，具有广阔的应用前景。

Based on the understanding of physiological pathway for broodiness, three genes related to broodiness including PRL, PRL receptor, and pituitary-specific transcription factor (POU1F1)-encoding genes were selected as candidates to screen the genomic variation by means of PCR-SSCP protocol and analyze the association with chicken broodiness and other target traits.

禽类血浆PRL水平上升与就巢行为的起始和维持具有密切的相关性，本研究采用候选基因的策略，通过分析就巢行为发生的生理机制，选择与就巢性状密切关联的PRL、PRL受体和PRL转录调控因子——垂体特异转录因子(pituitary-specific transcription factor，POUlF1)基因，采用PCR-SSCP分析检测基因变异，并分析基因变异与就巢性和其它目标性状的相关性。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
