| 摘 要： | 母猪营养状况对生殖机能有着重要影响,初情期启动与饲粮能量状况、后备母猪的最低体脂储备是其进入初情期的前提条件.通过科学的营养调控措施,有效满足母猪对饲粮能量的需求,是确保母猪发情正常启动及其后的繁殖周期正常的基本条件.本文主要对母猪发情机制进行阐述,立足调控饲粮中的能量水平和来源2个方面,综述了饲粮能量状况对母猪发情的...

| Abstract: | Nutritional status of gilts exerts a critical influence on reproductive function.onset of first estrus is closely related to dietary energy levels.The attainment of a minimum threshold for body fat is necessary for puberty onset.Efficiently satisfied dietary energy needs for replacement gilts through scientific nutritional regulatory measures is a basic factor to ensure normal onset of first estrus and breeding cycle.To provide some references for nutritional regulatory technologies of onset of first estrus... |
