Show FEED experiment WORTH MILLIONS saving to dairymen total 6 for each cow bore than a year Is the difference between feeding more than a million ot new york states dairy cows a 10 per cent or a 24 per cent concentrate grain mixture tills represents a saving of 0 a year or each cow to those dairymen who formerly fed the 24 per cent protein concentrate the animal husbandry department at cornell university has conducted the operative cooperative co grange league federation protein feeding trial since the fall of 1928 nr E S harrlson says that with medium clover mixed hay and corn silage a 16 per cent protein concentrate mixture of grain gave as much 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 digestible nutrients in the low protein ration were utilized by the cows with the 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 of its other ingre farmers who raise their own oais 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 ton of 24 per cent protein concentrate ration to use about pounds of expensive high protein feeds for every pounds of home grown grains such as ground oats and birley it Is dow known as a result of the experiment that a very satisfactory ration with a 16 per cent protein content may be mixed using only pounds of the high protein feeds for every 1200 pounds of ground oats and barley |
