This also lends flexibility to the protocol should labor or scheduling problems arise at the last minute. If heifers are not accustomed to eating at the feed bunk, start feeding a grain supplement two weeks prior to MGA feeding. MGA can be top dressed, but proper consumption rates are facilitated by thorough mixing of MGA into a grain supplement or a silage based TMR ration. MGA usually comes in the form of a pelleted protein supplement. The MGA-PGF system is ideal for many dairy operations because the heifers are already being fed in a feedlot situation.
Implementation is basically hassle free.
Although the MGA-PGF system also works great on beef cows and heifers where feeding facilities are available, MGA is not approved for use in lactating dairy cows.
