尽管面临严重的燃料短缺、药品匮乏及长期停电困境，古巴国家动物园近日成功繁育出四只孟加拉虎幼崽。[1] 其中包含一只罕见的白虎，这是该国第二次成功培育出的白虎。 [1] 此次出生事件发生在古巴每日柴油配额仅为 5 升（而动物饲养与维护实际需消耗 20 升）的背景下。 [1]
为维持动物园运营及动物生存，工作人员不得不依靠人力、马车以及电动三轮车来替代燃油车辆进行日常作业。[1] 该动物园占地面积达 375 公顷（约 926 英亩）。 [1] 古巴官方表示，若实施向自由市场经济转型的改革措施，有望改善包括动物园在内的物资供应状况。 [1]
The National Zoo in Cuba has successfully bred four Bengal tiger cubs, including a rare white tiger [1]. This marks the second time the country has achieved successful breeding of white tigers [1]. The births occurred against a backdrop of severe fuel shortages and long-term power outages affecting the nation [1]. While zoo operations require 20 liters of diesel daily for feeding animals and maintenance, staff are currently allocated only five liters per day [1]. To cope with this deficit, workers have resorted to using horse-drawn carriages and electric tricycles instead of motorized vehicles [1]. The National Zoo spans an area of 375 hectares (926 acres) [1]. Officials stated that implementing reforms toward a free-market economic model could improve the supply situation for materials at the zoo [1].
