THIRTY-SEVENTH ANNUAL CONVENTION. 265 



long periods of green or succulent feeds. Linseed meal takes 

 the place of the high price patent tonic stock feeds and costs on 

 an average only about one-tenth as much. Every well regu- 

 lated stock farm should always be provided with linseed meal. 

 Miscellaneous Feeding Trials. 



Observations have been made as to the effect of feeding 

 cows a ration containing one-third cottonseed meal during the 

 month preceding calving. No ill effects of such feeding were 

 noticeable. It should be borne in mind, however, that the cows 

 received a liberal amount of corn silage during the time these 

 observations were made. Our feeding trials have well estab- 

 lished the fact that cottonseed meal can be fed with much 

 greater safety in conjunction with silage than with dry rough- 

 age. 



In another investigation involving over twenty animals 

 observations were made on the effects of feeding a grain ration, 

 consisting of one-third cottonseed meal, to heifers ranging from 

 six to eighteen months of age. The daily grain allowance 

 ranged from one and one-half pounds for the six months' old 

 heifers to two and three-quarter pounds for the eighteen months' 

 old heifers. The amount of meal fed in these trials did not 

 aappear to interfere in the least with the vigor and development 

 of the animals. One-half of the roughage fed consisted of corn 

 silage. 



Investigations have also been made on the effects of feed- 

 ing calves on old pasteurized milk and on skim-milk soured with 

 pure cultures of lactic acid bacteria. In the main, the old pas- 

 teurized skim-milk did not appear to have any appreciable effect 

 on calves, though the same had a tendency to produce scours 

 when badly curdled. Feeding skim-milk sourced with lactic 

 acid bacteria did not induce scours; on the contrary, such milk 

 had an appreciable constipating effect. This constipating effect 

 was so marked as to prove quite efficacious in checking calf 

 scours. More data is needed to positively prove to what extent 

 skim-milk soured with pure cultures of lactic can be used as a 

 cure for calf scours.
