智能饲喂器与保温灯对哺乳母猪生产性能及仔猪发育的影响OA

[Objective]This study aimed to investigate the effects of intelligent feeders and heat lamps on the production performance of lactating sows and the development of piglets,providing a practical basis for the application of intelligent breeding equipment in lactating sow production.[Method]A total of 120 lactating sows were randomly divided into three groups:experimental group A(n=60)using intelligent feeders,control group B1(n=30)using semi-automated wet feeding,and control group B2(n=30)using semi-automated dry feeding.Furthermore,experimental group A was subdivided into subgroup A1 using intelligent heat lamps and subgroup A2 using traditional heat lamps for a comparative trial.[Result]Intelligent feeding increased the sows'feed intake and backfat thickness stability,and effectively increased the weaning weight of the piglets.The intelligent heat lamps increased piglet survival rate by 1.59 percentage points,increased piglet huddling rate by 6.8 and 6.1 percentage points respectively at 17 and 21 days of age,and reduced electricity consumption by 31.22%.[Conclusion]Intelligent breeding equipment can effectively optimize sow reproductive performance,improve the piglet growth environment,and reduce production costs,offering a feasible pathway to promote the intelligent transformation of the livestock industry.
