宁夏“装死”小羊身价飙至30万，主人仍拒绝售卖；专家：“装死”并非“演技”在线，系因遗传缺陷，可人工繁殖更多只

Core Viewpoint - A newborn lamb from Ningxia's Pingluo County has gained significant popularity online due to its unique "playing dead" ability, leading to a dramatic increase in its value to 300,000 yuan, making it a social media sensation and a local ambassador for its hometown [2][3]. Summary by Sections - The lamb's owner has refused to sell it despite its skyrocketing price, naming it "Yang Rou Chuan" (Lamb Skewers) [3]. - The scientific explanation behind the lamb's "playing dead" behavior is attributed to a genetic mutation causing a hereditary defect, resulting in a natural response called "muscle rigidity" when stimulated by external factors. Selective breeding of such traits could lead to more lambs exhibiting this behavior [3]. - Initially, the owner brought four lambs to sell at a market, with three selling for the common price of 420 yuan each. However, the lamb displaying the "playing dead" behavior was not sold due to buyers' misconceptions about its health [3][5]. - The lamb exhibits a unique response where it "plays dead" when adults approach, but behaves normally and interacts playfully with children, showcasing a selective response to different stimuli [5]. - The videos of the lamb have garnered over ten million views across multiple platforms, contributing to its increased value, which has surged approximately 714 times from its initial price [5].
