| 摘 要： | 为研究不同粗纤维水平日粮对妊娠母猪生殖激素水平的影响,选用30头胎次、配种时间及体况均相近的经产PIC配套系父母代母猪,随机分成5组,妊娠期间分别饲喂含3%、5%、7%、9%和11%的苜蓿草粉粗纤维日粮,通过调节各组的饲喂量,使其所摄入的能量、蛋白、钙、磷等水平基本一致。3%为对照组,日粮中不另加粗纤维。研究结果显示:提高日粮中粗纤维水平会降低妊娠各阶段母猪雌二醇的浓度,但增加妊娠后期孕酮和催乳素的浓度,且当日粮中粗纤维含量达到9%时效果最佳。

| Abstract: | The aim is to study the effect of dietary fiber on reproductive hormones of sows.Thirty PIC sows with similar parity and breeding time were randomly divided into 5 groups which provided dietary with 3%,5%,7%,9% or 11% of crude fiber during pregnancy,respectively.Alfalfa powder was used to control fiber level based on 3% group(control group),and feed intake was adjusted to balance energy,protein,calcium,phosphorus.The results showed that: improving the level of crude fiber in the diet could increase the levels of progesterone and prolactin,but decrease estradiol concentration,and the optimal level of dietary fiber was 9%. |
