"标准化-智能化-绿色化"养殖体系与传统限位栏模式养殖效果比较OA

In order to break through the bottlenecks of low productivity of sows,serious waste of resources and strong de-pendence on core technologies in the traditional gestation stall breeding mode of China's pig industry,this study took Liangzhou District as an example to carry out the integrated innovation and demonstration promotion of the intelligent group breeding pre-cision management system for breeding sows in cold and arid regions.By integrating key technologies such as standardized ener-gy-saving livestock house construction,intelligent precision feeding,environmental protection sewage disposal and digital man-agement,a"standardized-intelligent-green"breeding system was constructed,and a control test was carried out with the tradi-tional gestation stall mode.The results showed that under the intelligent group breeding mode,the annual productivity of sows reached 22-24(an increase of 50%-70%),and the number of live births per litter was 11-12(an increase of 20%-22%);the feed conversion rate was optimized to 2.8-3.0∶1(a de-crease of 19%-24%),while achieving 80%water saving and 30%reduction in labor costs.The integrated technology and standards formed by this study fill the application gap of in-telligent group breeding in the northwest region,and provide key technical support for the transformation and upgrading of the pig industry.
