British Dairy Farming. 
for feeding dairy cattle, but in consequence of the excess of 
albuminoids, which, however, are reduced by the admixture of 
rye-grass, it is necessary to add to a cow's ration some of those 
foods which are most easily obtainable by farmers, such as roots 
and straw. The crop in question, trifolium and rye-grass, was 
as a ration equal to one part of albuminoids to three parts of 
carbo-hydrates, and was given to the cattle with the following 
mixture : the figures showing the feeding or nourishing con-

Neither ration is a heavy one, but being used for beasts not 
exceeding 750 lbs., it will be found ample for ordinary purposes 
in each case. For example : if 15 lbs. of digestible solids are 
sufficient for a beast of 1000 lbs. weight not giving milk, 
11*25 lbs. will be sufficiently near the mark for a beast of 
750 lbs., and as each additional unit of solids is believed to be 
sufficient for the manufacture of 10 lbs., or a gallon of milk, 
although I prefer 1'25 lbs., we have here a surplus of 3*29 lbs. 
of solids, equal to the manufacture of 13 quarts of milk, 
considerably more than the average Jersey cow gives — the 
cost of the entire ration being from \ld. to Is. a day. Swedes 
have been invariably used with trifolium, and provided the 
crowns have been cut off — the milk carefully creamed by sepa- 
ration, and the butter made in the most cleanly and skilful 
manner — no trace of flavour commonly supposed to be attached 
to swede-feeding has been perceptible, the butter having been 
of the highest quality. The experience has been sufficient to 
show that trifolium is not only an extremely cheap crop, but
