Show ( (Ht SlI.AGI'l GOOD I OK 1AIKV CATTLE s.ws i:Pi:itr lly Gcoi-go i;. Cuino, U. S. A. '. Extension Daii yinnn In the middle wts. a dairy farmer without corn snag'.; will usually apologize for being out of, what is considered there, the most important feed. In Utah whet? alfalfa can be produced much move cheaply, silage is not consid-erde consid-erde quite so essential, and yet It is one of the best crops that can be grown for milk production. Work done by Carroll at the Utah Experiment Station several years ago, and reported in bulletin No. 190, corresponds very closely with results recently published from Utah Station Bulletin No. 239. Will on fed with grain and alfalfa al-falfa to dairy cows it requires 2'.i to 3 pounds of corn silage to replace re-place one pound of alfalfu. A common com-mon rule for feeding is. 3 pounds of silage per day for each 100 pounds of liveweight of the cow. Each cow then would receive from 20 to 40 pounds per day, depending depend-ing on the size of the animal. In .sections where market milk is being be-ing produced, silage should he fed carefully to avoid any possibility of its tainting the milk. Usually, if it is fed right after milking and properly cleaned up before the next milking ar.d the barn, aired thoroughly there should be very little or no trouble. Corn silage should not be feci to calves younger than S to 10 months, as it may help to cause scours. It is a very satisfactory feed for heifers from 10 months or older and it has a higher replacement re-placement value than 3 to 1 as given alone. At the Missouri Station, as recorded re-corded in Bulletin No. 158, yearling yearl-ing heifers were fed alfalfa and corn silage at will. Each heifer ate 14.4 pounds of silage and 6.6 pounds of alfalfa per day. On this ration these heifers gained .24 of a pound more than normal. The alfalfa fed in Missouri was not so bright and palatable as most Utah alfalfa which difference might affect the rate of consumption somewhat. There are very little available data on the feeding of corn silage with alfalfa hay alone.. Most experiments ex-periments have grain in the ration. I A few cows that are being fed at the Utah Station oh alfalfa and corn silage only, at the present time show very satisfactory production. pro-duction. This is one of the most economical rations that Is available avail-able for the Utah farmer. Dairymen who contemplate planting corn for silage may obtain ob-tain information regarding the time to plant and the varieties best suited for any particular location lo-cation by asking a county agent or by writing to the Extension Service, Ser-vice, Utah State Agricultural college, col-lege, Logan. |
