Excerpt: ...shows the average daily consumption of air-dry feed per head and also the amount eaten per 1,000 kilograms live weight, computed both directly in proportion to the weight and in proportion to the twothirds power of the live weight, i. e., to the surface. Table 53.--Air-dry feed eaten. Steer A Oct. 1 to Dec. 11, 1904 Mar. 31 to July 13,1905 July 13 to Sept. 28,1905 Sept. 28 to Nov. 28,1905 Apr. 6 to July 4,1906 July 4 to 28, 1906 July 28 to Oct. 27,1906 Oct. 27 to Dec. 4,1906 Average Steer B Oct. 1 to Dec. 11,1904 May 5 to July 13,1905 July 13 to Sept. 28,1905 Sept. 28 to Nov. 28,1905 Apr. 13 to July 4,1906 July 4 to 28, 1906 July 28 to Oct. 27,1906 Oct. 27 to Dec. 4,1906 Average The greater consumption of coarse feed by steer B on the limited grain ration has already been noted and is reflected in the foregoing table. While the air-dry matter consumed per head is greater in the case of steer A, the consumption is relatively greater by steer B, whether calculated in proportion to the weight or surface, with a single exception in the latter case. Accompanying this greater consumption of feed by steer B we find (omitting the doubtful period, July 4 to 28, 1906) that in four cases out of the seven, steer B produced a unit of gain in live weight on less air-dry feed than did steer A, the average of the whole time being decidedly in favor of the former animal. Judged merely from the standpoint of the increase in five weight therefore, steer B appears to have been on the whole a more economical producer than steer A up to December 4, 1906. On pasture during the following summer, however, steer A gained 50 per cent faster per head than did steer B and a little more rapidly per 1,000 kilograms live weight. Steer A reached a greater final weight...
