Purpose: Investigate Cone Vision in Bovine Eye Methods: EM, Cell preparation, Detergent extraction, Spectroscopy Results: Cells of structure similar to cones in other systems are present Conclusions: There is bovine cone vision. A large portion of all biochemical studies done on mammalian photoreceptors have used bovine rod preparations. We have shown this retina also has cones, but their small proportion (The total cone visual pigment membrane area is of the order of 1% that of the rods) has caused them to escape notice in the earlier studies.. We are investigating the spectral sensitivity of these cones, both in comparison to the well known rhodopsin, and to see whether the snorting bull really sees the matador's red cape.
