K. Stelwagen et al., MAMMARY-DERIVED GROWTH INHIBITOR IN BOVINE-MILK - EFFECT OF MILKING FREQUENCY AND SOMATOTROPIN ADMINISTRATION, Canadian journal of animal science, 74(4), 1994, pp. 695-698
The effects of milking frequency and exogenous somatotropin on milk MD
GI were investigated in cows. High levels of MDGI in milk were found d
uring lactation; however, despite significant changes in milk yield, n
either milking frequency nor somatotropin affected MDGI. The data do n
ot support a role for MDGI in acute regulation of mammary synthetic ab
ility.
