$91.80; the average returns per 100 lbs. expended for lee<] $1.80; and the aver- 

 age cost of feed per quart of milk 2.8 cts. 



Complete records are given of the feed consumed and cost of feed, together 

 with the weight and average gain in weight per day for eight calves, for a period 

 of six months. All of the calves were removpil from the dam immediately after 

 being dropped, and were fed whole milk during the first 30 or 40 days except 

 two of the calves which were put on skim milk soon after birth. It was found 

 that the average daily gain in weight was practically the same when the calves 

 were fed skim milk as whole milk. The grain ration consisted largely of bran, 

 gluten, and Ajax flakes. Grain was placed before each calf when they were 

 about three weeks old and they were allowed to consume both grain and alfalfa 

 at will. 



It was found that when a small amount of oat meal and soaked beet pulp was 

 added to the grain ration for the calves during the first few weeks they would 

 consume more than when the straight grain mixture was fed. Another satis- 

 factory mixture was found to be corn-and-cob meal, bran, and linseed meal, 

 8:4:1. 



Data are given on the average daily rations, production, feed cost, and profit 

 of cows of the various breeds as determined by records obtained in advancel 

 registry work. 



[Dairy husbandry], C. T. Ames {Mississippi 8ta. Bui. 165 (1914), PP- 23- 

 26). — At the Holly Springs substation the estimated cost of keeping a cow for 

 12 months was $47.33, which included 150 days winter feeding at 15.5 cts. per 

 day and 210 days of summer feeding at 4.8 cts. per day. It is stated that if 

 the value of the manure is allowed to offset the cost of labor in running the 

 dairy, each cow produced a net average of about $65.16, which does not take 

 into account the skim milk fed to pigs and calves nor the calves themselves.

Milk records and cost of feeding cows in Berkshire, 1913, J. M.\ckintosh 

 (Univ. Col. Reading, Dept. Agr. and Ilort. Bui. 19 [1913^, pp. 56).— Data are 

 given, collected from 12 farms in Berkshire. England, on the cost of winter and 

 summer feeding of dairy cows. A great variation was found among the several 

 farms, and it is concluded that a material lowering of the cost of production 

 could be effected if farmers would keep milk records and feed records and act 

 on the information thus obtained. 



[Milk production] {Mark Lane Express, 112 {1914), ^'o. 43S9, p. 5S9, fig. 1).— 

 In connection with investigations carried out on a number of farms in Yorkshire. 

 England, it was found that though high yield and low fat content and low yield 

 and high fat content do not invariably go together, yet in the case of cows 

 yielding under 400 gal. of milk, the milk contained an average percentage of 

 3.92 of fat. The percentage decreased with an increased milk production, and 

 the milk of cows yielding over 1.000 gal. contained only 3.48 per cent fat. 



The importance of milking at regular intervals was shown by the fact that 

 of the 18 samples containing less than 3 per cent fat in the morning milk, no 

 fewer than 13 were contributed by a farm where the intervals were very 

 unequal. It w^as observed that while the lengthening of the night interval tends 

 to raise the yield of milk and lower the percentage of fat in the morning milk-
