On account of her immaturit}' no attempt was made to crowd the cow, and 

 the ration was kept below the standard. 



The American standard ration would require for a cow of her weight, 1,550 

 Ibs., 3.41 Ibs. of protein, 20.61 Ibs. of carbohydrates and 1.085 Ibs. of fat per day. 



The cow ate her feed with avidity every day, and was always vigorous, 

 playful and perfectly healthy. 



The total dry matter eaten in the twenty-one weeks was 5,276.03 Ibs., equal 

 to 35.89 Ibs. per day, or 23.18 Ibs. per day per 1,000 Ibs. live weight, the average 

 weight of the cow for the winter being 1,550 Ibs. 



The total fat yield for the twenty-one weeks was 230.67 Ibs. There was 

 therefore 22.87 Ibs. dry matter on the average eaten for each pound of fat 

 yielded. 



The cost of the feed for the same period was $40.75. Dividing this sum by 

 230.67, the number of pounds of fat, we have the feed cost of one pound of fat, 

 viz.: 17.66 cents, if no cognizance is taken of the value of the 6,120 Ibs. of 

 skim milk yielded at the same time, which, at 20 cents per hundred, was worth 

 $12.24. Subtracting from the $40.75, total food cost, this value of the skim milk 

 we have the net food cost of the fat $28.51 or 12.35 cents per pound. 



After turning to pasture in the early days of May, 1895, the grain feed was 

 continued with some modification. To the 20th of May the daily grain feed 

 consisted of 2 Ibs. of oil meal and 18 Ibs. of a mixture of 100 Ibs. of corn, 60 Ibs. of 

 oats, 85 Ibs. of bran and 50 Ibs. of wheat. After May 20 the wheat was dropped 

 and the cow received 18 Ibs. of corn, oats and bran in the proportions just given 

 with 2 Ibs. of oil meal. This continued until July 13, after which the daily 

 grain feed was made up of 6 Ibs. of a mixture of equal parts of gluten meal 

 and wheat bran, 12 Ibs. of the mixture of corn, oats and bran, and 2 Ibs. of oil 

 meal. 



The drouth was excessive in the early summer, and the pastures were nearly 

 an entire failure after the middle of July. The cow was therefore shut in the 

 stable during the heat of the day and fed on green corn and hay in addition to 

 the grain. 



She had been accustomed to receive on the average 35.89 Ibs. of dry matter 

 per day while in the yard before turning to pasture. To obtain as much from 

 pasture grass, which contains about 80 per cent water, she would need to con- 

 sume 179 Ibs. daily, the gathering of which alone would be a formidable under- 

 taking, even for as vigorous a cow as this one. To relieve her of the necessity 

 of carying such a mess of succulent material through her stomach and bowels 

 the grain ration was kept up. 



The milk flow rose toward the end of May and was fairly constant through 

 June, July and August. The regularity as well as the unusual size of the yield 

 is undoubtedly to be attributed to the grain feed with the pasture. 



In the four months of May, June, July and August she consumed $21.77 

 worth of grain. 



The pasture throughout July and August was so poor as to form but an 

 inconspicuous part of the ration. Counting its value with the supplementary 

 green fodder and hay for 123 days as $10.00, the total cost of the feed of the cow 

 for the four months would be $31.77. 



The milk yield for the same period was 6,608.5 Ibs., containing 195.92 Ibs. of 

 fat, equivalent to 228.57 Ibs. of estimated butter. Dividing the food cost, $31.77, 

 by this amount, the feed cost of a pound of butter would be 13.89 cents, with- 

 out reckoning the value of the skim milk, which at 20 cents per hundred would 

 be worth $11. 23. 



Rosa Bonheur 5th. This most remarkable of Holstein-Friesian cows is 

 another of the Michigan Experiment Station herd which has been so admir- 

 ably and skillfully handled by Prof. Clinton D. Smith. We make the following 

 extracts from the Station Bulletin: 



Rosa Bonheur 5th was calved March 20, 1888. On the 20th of February, 

 1894, therefore, when this record began, she was 5 years and 11 months old. 

 Her weight at that time and for the months following varied but a few pounds 

 from 1,750, until she became pregnant on the 22d of June, 1894, when it 

 rapidly ran up to 1,850 pounds by the close of the year. She is therefore a 

 very large cow. In general outline she approaches the ideal dairy type, being 

 distinctly wedge shaped, deep through the sacrum and udder, and much less 

 so through the shoulder and brisket, with an immense belly and udder.
