202 MAINE; AGRICULTURAL EXPERIMENT STATION. 1904. 



Experiment No. 126. — Soy bean — corn silage. In this trial 

 only the steers were used and the silage was fed with some hay. 

 It will be noticed that the results are practically the same for 

 the silage as when it was fed alone. 



Experiments No. 1 19-127. — Hay. This hay was largely 

 timothy of fair quality. The steers in this experiment as in 

 Nos. 88-95 gave higher digestion coefficients than the sheep, 

 although this was a different lot of sheep. 



Experiments No. 120-128. — Linseed and corn meal. A mix- 

 ture of hay, linseed and corn meal was fed. The steers as 

 before gave slightly higher results, but the coefficients agree 

 quite well with the ones obtained in Experiment No. 113, par- 

 ticularly the protein. 



Experiments No. 121 -129. — Middlings. In these experi- 

 ments, through a mistake, two different lots of middlings were 

 used, therefore the results cannot be compared. 



Experiments No. 122- 123-124. — Cottonseed meals. These 

 meals are of different grades and the experiments were made 

 with sheep. These meals will be made a subject for discussion 

 in a later bulletin, consequently the coefficients obtained are pre- 

 sented here without comment. 



DISCUSSION OF RESULTS. 



In studying the table giving the coefficients obtained from the 

 steers and sheep, it will be noticed that there are differences 

 which are somewhat remarkable and should have some expla- 

 nation. In experiments No. 88-95 with hay alone, the steers gave 

 a coefficient over 6 per cent higher for the dry matter than the 

 sheep, but in the next two experiments when bran was fed with 

 the hay, the sheep gave higher coefficients for bran than the 

 steers. Also in experiments No. 91-98, when one part cotton- 

 seed meal to eight parts hay is fed, the steers show only 3 per 

 cent greater digestibility for the dry matter of the ration; and 

 in the following experiment, where two parts cottonseed meal 

 to eight of hay are fed, the steers digest only 1 per cent more of 

 the dry matter from the mixture. Calculating the digestibility 

 of the cottonseed meal for the sheep, using the coefficients 

 obtained in experiment No. 88 for the hay, gives a coefficient 

 for the dry matter of nearly 100 per cent when one part of cot- 

 tonseed meal is fed, and when two parts are fed about 94 per
