Abstract:
Salt (NaCl) is an essential nutrient for horses because their diet is low in sodium and they lose salt in sweat. Given the many types of salt block available, 342 horse owners were surveyed to see what type they offered their horses. The owners most often offered plain(30%) mineralized (29%) or Himalayan salt blocks. Next, adult mares were given two choice preference tests between plain (white) and mineralized (red) salt blocks, between mineralized and selenium (green) blocks, between plain and selenium, between Himalayan (pink) and plain and between Himalayan and selenium salt blocks. The horses preferred plain salt to Himalayan salt, but showed no preference between the other combinations.
摘要:
盐(NaCl)是马的必需营养素,因为它们的饮食中钠含量低,并且在汗液中失去盐。鉴于可用的盐块的多种类型,对342名马主人进行了调查,以了解他们提供的马类型。业主最常提供平原(30%)矿化(29%)或喜马拉雅盐块。接下来,成年母马在平原(白色)和矿化(红色)盐块之间进行了两种选择偏好测试,在矿化块和硒(绿色)块之间,在平原和硒之间,喜马拉雅(粉红色)和平原之间以及喜马拉雅和硒盐块之间。马更喜欢纯盐而不是喜马拉雅盐,但没有显示其他组合之间的偏好。
