Cattle Feeding Experiments. 5 



period. It was with the thought that these facts called to 

 the attention of the farmers might result in larger profits 

 from cattle feeding that the present series of experiments 

 was begun in 1903 and is being carried on at present. Fol- 

 lowing is a report of last winter's test (1905-06), the third 

 experiment in the series. 



As in former tests, the conditions with reference to shelter, 

 water, etc., were the same in all lots, the difference being 

 purely a question of rations fed. There were again ten steers 

 in each lot, distributed to make them as even in quality and 

 weight as possible. The entire number, sixty head of two- 

 year-old grade Herefords and Shorthorns, were purchased 

 from one ranch where they were selected from a herd of 250 

 to secure greater uniformity. 



TWO EXPERIMENTAL PERIODS OF FEEDING. 



Unlike former experiments, these cattle were fed during 

 the winter in two distinct periods, making two separate ex- 

 periments, the first being a comparison of the value of vari- 

 ous forms of roughness fed in liberal quantity both singly 

 and in combination, and the second a comparison of certain 

 so-called protein concentrates with a protein roughness, in 

 this case alfalfa hay. The separation into two experimental 

 periods was thought desirable because it also affords an in- 

 teresting comparison of the cost of production during the 

 early part of the fattening process when roughness was the 

 important factor, and the latter part when grain was fed 

 heavily and roughness sparingly.
