Copper Deficiency in Cattle

Dr. Greg Penner from the Dept. of Animal and Poultry Science returns as my podcast guest this week.  Greg is discussing some of his latest research efforts on the effects of high sulphate water on cattle performance and how we can mitigate some of the subclinical effects such as copper deficiency in high sulphate water situations.

00:00 – 2:00   Welcome and Introductions 

2:01 – 5:21   Where and when do we see high sulphates?

5:23 – 7:01   Polioencephalomalacia – nervous disease caused by high sulphates

7:02 –   9:25 Subclinical effects of high sulphates

9:26 – 11:32 Current guidelines for high sulphate levels

11:33 - 17:18 Describing results of a trial where high sulphate water was given to cattle

17:19 – 24:25 An attempt to mitigate high sulphates with Bismuth subsalicylate

24:26 - 27:38   Evaluating mineral strategies to mitigate the low copper caused by high sulphates

27:39 – 30:07   Next steps in future research

30:08 – 32:42   Recommendations for producers with high sulphate water or feed

32:43- 33:52   Wrap up
