A Michigan law declares that milk containing "less than 12J per cent 

 of solids or less tban 3 per cent of fat shall be deemed adulterated." Both 

 the Ayrshire and Holstein milk fell below the re^iired standard as re- 

 gards amount of total solids, though above the standard so far as fat is 

 concerned.

Feeding steers of diffeeent breeds, E. Davenport, M. S. — 

 The experiment here reported is similar to one reported in Bulletin No. 

 44 of this station (See Experiment Station Record, Yol. I, p. 84). The 

 object of both of these experiments was to determine, as far as pos- 

 sible, " whether or not, jiroperly speaking, there are such things as breed 

 differences, aside from form, color, etc., and if so, what are their charac- 

 ter and extent? Are they sufhcieut to distinguish one breed above 

 another ? " 



As nearly typical specimens as it was possible to secure of live breeds 

 — Galloway, Holstein, Hereford, Shorthorn, and Devon — were used. 

 The animals "were all purely bred, and were such as were furnished by 

 breeders of the several breeds." There were originally two of each 

 breed, but owing to accidental circumstances one Shorthorn and one 

 Devon were dropped. The feeding stufls were at all times the same for 

 all the animals, but the amount fed was regulated by the individual 

 appetites. The grain consisted of corn and oats (either whole or ground), 

 bran, and " oil meal ; " the coarse fodder was mostly mixed hay (timo- 

 thy and clover), with roots, corn silage, cut grass, fodder corn, and some 

 pasturage. " The influence of different kinds of feeding stuffs has not 

 entered into this experiment." The record of the feeding extends from 

 March 10, 1889, to September 5, 1890, eighteen months. "All of the 

 animals led well and were healthy and vigorous during the entire ex- 

 periment." They were all slaughtered at the end of the trial. Tables 

 record for each animal the amounts of each kind of feed consumed, 

 gain in live weight by months, and the dressed weight, shrinkage, 

 weights of fore and hind quarters, hide, tallow, intestines and paunch, 

 head, feet, tail, liver, lungs and heart when slaughtered. Some of the 

 more important data are summarized in the following statement:
