EXPERIMENT STATION RECORD. 



different amounts of cotton-seed meal. The sheep were kept in suitable 

 stalls and were fed corn silage morning- and noon and with mixed hay 

 at night for a few days before the tests proper began. The experiments 

 were conducted by the usual methods. The weights of the sheep were 

 recorded in every case. When cotton-seed meal was fed with the 

 timothy hay or crab-grass hay, the digestibility of the hay alone was 

 computed by taking into account the coefficients of digestibility of the 

 cottonseed meal as determined in previous experiments. The coeffi- 

 cients of digestibility of the different rations is shown in the following 



table:
