C2-Lancaater Farming, Saturday, October '5, UREA AND MINERAL ADDITIVES FOR CORN SILAGE Com silage is a popular and effective feed for both feedlot steers and for wintering cows and calves. However, com silage is deficient in protein, calcium and phosphorus for most classes of beef cattle. Table 1.

Adding urea, limestone, or a combination has been shown to increase the pro duction of organic acids in the sil age. Of particular importance is the increased production of lactic ' acid during fermentation. A dry urea usually has 4S per cent nitrogen, which is equivalent to 281 percent crude protein for a ruminant By adding 10 pounds of urea to com silage that is 30 per- v cent dry matter and 8 percent fjgasi Agriculture - Residential - Commercial Invest In Concrete, Quality Work that Will km A Lifetime CALL FOR FREE ESTIMATES CONTACT AND SEE HOW AFFORDABLE ROY BBNSENIG CONCRETE WALLS CAN BE 717-355-0726 Authorized Dealer For Keystone Concrete Products E 2) pP) E W © E CONCRETE J WALLS.

Research at Ohio State and Illinois has shown a slight advantage in performance for cattle on urea-treated silage compared to when urea was added as a supplement at feeding. Some other important steps in using urea and mineral-treated sil age include: • Get a feed sample of the silage analyzed after the material has fer mented to be sure rations are balanced correctly. • There is some indication addi- SCS Approved Manure Storage Facility tional sulfur may be of benefit in rations which use urea as the prim ary protein source. * Use untreated silage or hay to start stressed calves in a feedlot. * Calves under four months of age will not be able to use the urea as protein until their rumen is more fully developed. * Add the prescribed amounts of urea and minerals to the silage because these materials can become toxic to the animal when fed at levels which are too high. It is essential to know the dry matter value of the silage before attempting- to mix urea and miner als with it. In general, urea can be added to silage that is 30 percent and 40 percent dry " matter. When the silage is too wet, the urea may escape as seep age, and when it is too dry the urea may be lost as am- monia and make the silage unpalatable. .25 ; .29 .22 For All Your Concrete Walls And Construction Needs Table 2.
