Feeding Potassium Carbonate to the Early Lactation Dairy Cow by Dr. Joseph Harrison

October 6, 2016


Check out this segment from Dr. Joseph Harrison, from Washington State University, as he dives into his first segment of a three part series on Feeding Potassium Carbonate to the early lactation dairy cow. This series will be summarizing their research at Washington State University on this important topic.

What you will learn:

1) Cows in early lactation can be in negative potassium (K) balance.

2) Supplementation of potassium carbonate sesquihydrate increased milk fat production in cows with “normal” fat test.

3) Supplementation of potassium carbonate sesquihydrate resulted in greater persistency of milk production.
