ABSTRACT
Results of an investigation using 18 cows in which three methods of drying off cows were studied and compared are reported. The methods considered were incomplete milking, intermittent milking, and complete cessation of milking. The data show that complete cessation of milking can safely be recommended as a method for drying off cows producing at least up to 20 pounds daily. Cows can be dried off in less time by this method than by either of the other two methods considered. No significant difference was noted in the quantity or quality of milk in the lactations following the drying up of cows by the three methods used.
Attention is called to the probable desirability of not disturbing the re-sorption phenomenon through intermittent or partial milking when drying off cows. Drying off cows through complete cessation of milking conserves leucocytes that may have an important function in resorption.
