Show FEED experiment WORTH MILLIONS saving to dairymen total 6 for each cow more alun a year Is the difference between feeding more than a million of bew york states dairy cows a 10 per cent or a 24 per ent protein concentrate grain mixture this represents a saving of 0 a year for each cow to those dairymen who formell for merl fed the 24 per cent protein concentrate ibe animal husbandry department at cornell university has conducted the co operative grange I 1 eague federation protein feeding trial since the fall of 1028 ur C S harrlson says that medium clover mixed hay and corn silage a 16 per cent protein bonien mixture of grain gave as muan milk as a 20 or 24 per cent mixture and that there was no evidence of any stimulating effect of protein on milk secretion also that the total ble nutrients in the low protein ration were utilized by the cows with tha same efficiency that the high protein ration showed the meaning of this being that 16 per cent protein content Is not low enough to effect the balance of a dairy ration so as to reduce the relative efficiency of its other ingre farmers who raise their own cats and barley will be further benefited because they will be able to use a much larger proportion of home grown grains when mixing their own dairy rations whereas it was necessary in mixing a ion of 24 per cent protein concentrate ration to use about 1200 pounds of expensive high protein feeds for ev ery pounds of home grown grains such as ground oats and barley it Is low known as a result of the experiment that a very satisfactory balry ration with a 16 per cent protein content may be mixed using only pounds of the high protein feeds tor every 1200 pounds of ground oats and barley table tells amount of grain dairy cow needs A dairy cow that gives dally 80 pounds of milk testing 3 per cent of fat should have 75 pounds of grain dally if the butterfat butter tat content was 4 per cent she should get pounds of grain according to the new dairy feeding table devised by J W avery of the new york state college of ag for dairy record club mem bers bor a cow giving 40 pounds of milk the same difference in test changes the grain requirement an fn m pounds to pounds and for a 0 pound cow from 15 pounds of grain to pounds the table gives the amount of grain ordinarily required by cows giving from 8 to 52 pounds of milk dally ranging in test from 25 to 7 per cent the table emphasizes the need ot knowing both how much milk a cow gives and the test of feed economical ly mr avery suggests feeding more grain if the cow Is thin if she Is not eating her full allowance of roughage if she continues to give more milk if near the end of the lactation period and heffers heifers still growing should ge from 4 to 5 pounds more grain than the table indicates the feeding table with explanations of its use and suggestions for rations using home grown grains la available free OH request to the department of animal at the new york sante college of agriculture at ithaca new york permanent pastured are rich source of protein permanent pastures may be made a rich source of valuable protein if a few simple practices are followed according to soil extension specialists at the ohio state university the average pastur Ct they point out returns from 00 to pounds of beet per acre this at 10 cents a pound equals 0 to W per acre less taxes fences miscellaneous cost and cost of wintering under such conditions th permanent pasture does little more than meet expenses however tests in ohio wisconsin vermont and new jersey all show that with a small investment in improving pastures they may bo made one of he most profitable pieces of land on the farm in an ohio test pounds of protein were produced on one acre of improved pasture which Is equivalent to 78 worth of dairy feed calculated on the basis of 24 per cent dairy feed at 48 per ton in wisconsin 74 pounds of protein valued at per acre were produced in a saries of tests clean milk utensils it Is estimated that fully 5 per cent of the bacteria in milk immediately after it Is produced can be traced to the utensils in which the milk waa handled the contamination resulting from improperly cleaned and sterilized utensils can be reduced by rinsing the utensils in a amorine disinfectant immediately before using the does not take the place of proper sanitation and cleaning of the however thorough and scalding are imperative |
