milk was 0.42 et. iter quart and that of Ijutter 5.1 ets. per pound less from the 

 former than from the latter ration. The hutter produced from the dried dis- 

 tillers' grains was firm, of good quality, and very marketahle. 



In continuation of an experiment previously mentioned (E. S. 11., 19, p. 272) 

 soiling crops v. silage and oat and pea hay as summer feed for dairy cattle 

 wei-e studied, using 4 cows instead of a whole herd as in the preliminary experi- 

 ment. Records were kept of the yield of milk and butter and the cost of each 

 ration during two periods of 15 days each. In respect to the yield of milk and 

 of fat, and to the gain in financial returns, there was no appreciable difference 

 in the use of either ration. The quality of the millv did not materially change 

 and there was no preceptible difference in the appearance of the animals or in 

 their weight. In the autlioi-'s opinion the results indicate that corn silage can 

 be fed safely and economically during the summer months. 



Report of experiments on the feeding of dairy cattle, E. Porter {County 

 Council Lancaster, Ed. Com., Agr. Dept., Farmers'' Bui. 5, pp. 37). — The experi- 

 ments reported were carried out to test the relative values of bone meal, un- 

 decorticated cotton cake, and gluten meal as indicated by the quantity and 

 composition of the milk produced and also by the flavor and quality of the 

 cheese and butter made from the milk. One test was made during the summer 

 and another test during the winter. 



The heaviest yield of milk and the largest profit were produced in the summer 

 test by the cotton cake and in the winter experiment by the gluten meal. In 

 both experiments the various feeds did not appreciably influence the percentages 

 of fat or of solids-not-fat in the milk. In the course of these experiments it was 

 observed that a fall of rain after a period of drought caused an immediate im- 

 provement in the fat content of the milk. Bone meal was best for the produc- 

 tion of cheese, gluten meal giving results nearly equal to it, liut cotton cake not 

 being so satisfactory. For the production of butter, bone meal was also the 

 best, but was followed closely by the cotton cake. 



In an appendix to this publication an account of milk tests is included, from 

 which the conclusion is drawn that " the total yield of milk, and the percentage 

 of fat contained therein, can be estimated with approximate accuracy by testing 

 on one day each fortnight and multiplying the average of the two tests by 

 fourteen." 



Third year's coniparison between potatoes and turnips as food for milch. 

 cows, 11. IsAACiiSEN (Bcr. Xo/T/cs- Laiidhr. JIdislcoJrs Yirks., IHOG-l, itp. 213- 

 22'/). — In quantities of 6, 10, or 11 kg, per head daily, potatoes replaced similar 

 quantities of dry matter in turnips in the rations of 12 cows, Xo unfavorable 

 influence on the quality of the butter or its chemical characteristics (iodin 

 number, Reichert-Meissl number, or water content), nor on the general health 

 and well-being of the cows, resulted from the feeding of potatoes. 



Home-grown cattle feeds, J, B, Lindsey (Massachusetts Sta. Bui. 120, pp. 

 36-38). — The author discusses home-grown and commercial cattle feeds and 

 points out the high A-alue of corn, clover, and alfalfa as compared with com- 

 mercial products. 



Purchased cattle feeds, J, B, Lindsey (Massachusetts 8ta. Bill. 120, pp. 38- 

 ■'/O). — Data are summarized regarding the composition of commercial cattle 

 feeds as sho^m by digestion experiments carried on at the station. 



Complete rations for dairy stock, J, B, IjINDsey (Massachusetts Sta. Bui. 



120, pp. '11-43) A number of mixed rations are suggested and a table is given 



showing the local market prices of cattle feeds for 1007.
