| 摘 要： | 随着中国养猪业设施化、自动化和智能化的高速发展和动物福利观念的普及,母猪群养成为一种新的饲养模式。以BigFarmNet母猪智能化群养饲喂系统为平台,对母猪群养模式进行了初步研究,分析了在群养模式下妊娠母猪的繁殖性能,并探讨了合适的管理模式,以期为母猪智能化、精细化饲养提供参考。结果表明,群养模式下母猪总产仔数和产活仔数分别为11.52头/窝和10.74头/窝,与平养+限位模式(分别为12.81头/窝和12.12头/窝)无显著性差异,群养模式初生窝重和个体重明显低于平养+限位模式,但21日龄窝重较高。群养系统转栏模式和饲喂曲线仍需要进一步的研究。

Effect of Group Housing System on Reproductive Performance of Pregnancy Sows |
| |
| Abstract: | s:With the rapid deve1opment of faci1ity,atomized and inte11igent pig industry,and the popu1arized ideas of anima1 we1fare,the grouping housing system became a new mode of sows' feeding. In this study the effects of group housing system on the reproductive systems were ana1yzed based on the BigFarmNet grouping housing system. And the suitab1e managements were a1so discussed. The resu1ts showed that the tota1 number of born and a1ive number of born was 11.52 and 10.74,re-spective1y,which showed no significant differences with the conventiona1 sow sta11 (12.81 and 12.12 头,P>0.05). The 1itter weight and average body weight at birth of the sows in grouping housing system were evident1y 1ower than that in convention-a1 sow sta11,but the 1itter weight at 21 days of age was rather contrary. The transference modes to grouping housing system and feeding curve for pregnancy sows needed further study. |
