“The practice of partial milking after calving has been shown to be of no use in preventing milk fever relapses” page 63 Herd Health Hoard’s Dairyman Books

“…the serum concentration of CA did not increase in any of the two groups of cows, and there was no relationship between serum Ca and the CA secreted via colostrum, so it is concluded that partial milking of colostrum, both at the first and second milking postpartum, does not prevent hypocalcemia in the early hours postpartum” page 131 Czech Journal of Animal Science, 59, 2014 www.agriculturejournals.cz/publicFiles/116524.pdf
"The complete milking of cows immediately following parturition did not increase the incidence of parturient paresis or was the average total serum calcium greatly different for the two groups" page 173, Journal of Dairy Science Vol 31, Issue 3, March 1948 www.sciencedirect.com/science/article/pii/S0022030248921924
I looked on google and google scholar out about 15 or 16 pages for each – not cherry picking studies. I looked for all studies addressing this regardless of results. I found references that promoted partial milking as a preventative or treatment for milk fever but none that provided any evidence that it worked. Some of them provided theories – such as the calcium remains available because it isn’t lost as the milk leaves the cow. However, other research indicates it is something other than the lack of calcium that causes milk fever (high calcium diets increase the incidence of milk fever; amounts of calcium lost through milking don’t lower the amount of calcium in the blood, etc.) I’m finding info on what that is but don’t have a firm handle on it yet.
