VALUE OF BUTTER MILK.

Buttsr milk, provided no water is | added, is practically of the same valu« for feeding pigs as separator milk. But it must be borne in mind that butter milk from factories almost always has mixed with it a considerable amount of added water, sometimes as much as 50 per cent., and consequently by itself is not a suitable food for pigs. Many instances can be given of great mortality among piga fed solely on butter milk plus water to derive sufficient nutriment to supply the demands of nature. But when the deficiency in solids is made up by adding meal, or even grass, roots, or other fodder, pigs are found to thrive on the butter milk. A pig requires about 21b of feed equal to pollard per day per 1001b live weight, for the purpose of keeping up tha system ■ that is, to keep up the temperature, repair the waste of t ; ssue, etc.—and that butter milk contains 9 per cent. i water and 10 per cent, solids. From the results of trials with some hundreds of pigs it was found that animals of 50-1001b live weight consume on an average 3.351b per day. Pigs of 100-1501b live weight eat 4.791b per day, and those of 150-200 consume 5.9Ub per day.
