Vitamin A deficiency associated with drought conditions
I recently took part in a regular webinar series produced by the Beef Cattle Research Council. I try to listen to these webinars regularly because they provide a great learning resource and I encourage producers and veterinarians to sign up for the series.
In this webinar, we discussed the long-term implications of drought, which was a relevant topic because significant areas of Western Canada have dealt with multiple years of below average rainfall. In that presentation, I briefly mentioned a herd investigation I was involved with years ago concerning an outbreak of blindness in a group of newborn calves.
