Electroretinogram (ERG) flicker photometry was used to measure the spectral properties of cones in three common ungulates-cattle (Bos taurus), goats (Capra hircus), and sheep (Ovis aries). Two cone mechanisms were identified in each species. The location of peak sensitivity of an S-cone mechanism varied from about 444 to 455 nm for the three species; analogous values for an M/L-cone were tightly clumped at about 552-555 nm. Each of these three species has the requisite photopigment basis for dichromatic color vision and they are, thus, similar to other ungulates examined earlier.
视网膜电图（ERG）闪烁光度法被用于测量三种常见有蹄类动物——牛（Bos taurus）、山羊（Capra hircus）和绵羊（Ovis aries）——视锥细胞的光谱特性。在每个物种中都识别出了两种视锥细胞机制。三种物种的S视锥细胞机制的峰值敏感度位置在约444至455纳米之间变化；M/L视锥细胞的类似值紧密聚集在约552 - 555纳米处。这三个物种中的每一个都具有双色视觉所需的光色素基础，因此，它们与早期研究的其他有蹄类动物相似。
