282 EXPERIMENT STATION RECORD. 



is not sticky. The feed used had the following composition: Water 

 33.20 per cent, crude protein 1.14, ether extract 0.37, ash 5.82, crude 

 fiber 2.73, and nitrogen -free extract 56.74 per cent. 



Twelve Ayrshire cows at the Ultuna Agricultural Institute were fed 

 in 2 lots, one lot receiving tbe regular summer feed throughout the 

 experiment, while the other received up to 4 kg. of molasses feed in 

 addition. No deleterious influence of the feed on the health of the 

 animals was noticeable. The cows receiving it kept up in milk yield 

 and in live weight fully as well as those receiving the regular summer 

 ration. — F. w. woll. 



Feeding experiments with milch cows, T. Gunther (Milch Zt<j., 

 26 (1897), No. 22, p. 340). — Six cows were fed in 3 periods, receiving a 

 mixed ration with fodder beets in the first and last periods, and fodder 

 beets alone in the second period. The yield of milk fell off in the sec- 

 ond period (9 days), but there was no perceptible change in composi- 

 tion. In the third period the yield gradually increased, but the fat 

 content appeared to diminish. " The experiment showed that the 

 change from a ration of beets with grain to one of beets alone was not 

 capable of materially affecting the quality of the milk in 9 days." 



The yield of milk of two Cheshire herds, C. T. Parker (Jour. 

 Roy. A(jr. Soc. England, 3. ser., 8 (1897), I, pp. 136-141).— This is a 

 record of the yield from 1893-'96 of 2 herds of Shorthorn cows, one of 

 48 and the other of 52 cows, considered in connection with a record for 

 7 years previous. 1 



"In only 2 cases did the number of weeks in milk fall below 40. Tbe maximum 

 individual yield . . . reached 1,482 gal., so that this cow gave nearly 7 tons of milk 

 in a period of 50 weeks. In [another] case, the yield of 1,462 gal. in a space of 48 

 weeks is an equally noteworthy performance. Most of the high-yielding cows are 

 from 6 to 9 years of age. ... As examples of remarkable milking capacity . . . 

 No. 40 gave over 1,000 gal. per annum for 6 consecutive years, No. 37 for 5 years, No. 

 46 for 5 years. . . . Over a period of 11 years, the average annual yield per cow 

 ranged from 662 to 758 gal. at Grange Farm, and from 535 to 636 gal. at Woodhouse 

 Farm, the mean annual yield at the former working out at 631 gal., and at the latter 

 at 587 gal. per cow. Summarizing the whole of the results at both farms, we learn 

 that a continuous measurement extending over a period of 11 years of the yield of 

 between 80 and 100 cross-bred Shorthorn cows has given an average result equiva- 

 lent to about 630 gal. of milk per cow per annum.'' 



The composition of sows' milk, especially the fat content, 

 Petersen and F. Oetken (Milch Ztg., 25 (1896), No. 42, pp. 665-667; 

 26 (1897), No. 23, pp. 356, 357). — In the first paper the results are given 

 of the examination of 17 samples of sows' milk, taken with great pre- 

 caution. Tbe sows were of different breeds and various ages. The fat 

 ranged from 5.80 to 12.09 per cent and averaged 7.56 per cent. Only a 

 few determinations of solids and other constituents are given. The 

 total solids in the 2 samples examined were 18.09 and 18.74 per cent 

 respectively. The possible effect of time from farrowing, age, etc., is 

 discussed.
