养殖户状告牧原销售病猪，称损失几百万元！一审判了，牧原胜诉

Core Viewpoint - The court ruled in favor of Muyuan Foods' subsidiary, Wolong Muyuan, dismissing the claims made by Hongfu Agriculture for compensation related to alleged disease in pigs sold by Wolong Muyuan, citing insufficient evidence to support the claims [2][10]. Group 1: Legal Proceedings - The civil lawsuit involved a contract dispute between Wolong Muyuan and Hongfu Agriculture, with the court finding that Hongfu could not prove that Wolong violated contract terms or that the pigs sold were responsible for the outbreak of the disease [2][8]. - The court's decision was based on evidence that the pigs sold were healthy and met all legal inspection requirements, with no signs of disease at the time of sale [8][9]. - Hongfu Agriculture's claims for compensation amounting to 6.86746 million yuan were rejected by the court [2][10]. Group 2: Disease Outbreak and Impact - The outbreak of the disease, identified as Porcine Reproductive and Respiratory Syndrome (PRRS), occurred shortly after Hongfu Agriculture purchased 152 pregnant sows from Wolong Muyuan [4][5]. - Following the delivery of the pigs, symptoms of the disease appeared, leading to significant losses, with Hongfu estimating direct economic damages in the hundreds of thousands of yuan [5][7]. - The court noted that prior to the sale, Hongfu's farm had already been infected with the virus, as indicated by laboratory tests conducted on samples taken from their farm [8][9]. Group 3: Evidence and Findings - The court highlighted that Wolong Muyuan provided multiple health certificates confirming the pigs were free from major diseases, including PRRS, at the time of sale [8][9]. - Hongfu Agriculture failed to provide sufficient evidence to support claims of mixed group sales or improper vaccination practices by Wolong Muyuan [9][10]. - The court found discrepancies in Hongfu's claims regarding the number of pigs affected and the timeline of the disease outbreak, further undermining their case [9].
