seemed the feed was too coarse to be digested well by the young 

 calves ; one of them had to be taken off the test entirely. They 

 were given what they would clean up of a dry mash of equal parts 

 of ground milo, rolled barley, wheat bran with alfalfa hay. 



Group 3 was fed on a commercial feed known as Red Horn 

 Calf Meal. The calves in this group were given whole milk until 

 ten days of age, at wdiich time the calf meal was added gradually, 

 so that at about five weeks of age each calf would be on calf meal 

 exclusively. The directions of the manufacturers were followed 

 as to amounts and methods of feeding the meal. The calves of 

 this group were given the same dry grain mixture and alfalfa hay 

 as were fed to Group 2. No difficulty was experienced with this 

 group, and the results were satisfactory. 



The calves in Grouj) 4 were fed whole milk for about ten days ; 

 then started gradually on Red Horn Calf Meal. After about forty 

 days, they were gradually shifted from the commercial calf meal 

 to the homemade meal given under the discussion of Group 2. 



This has seemed the most practicable method of using substi- 

 tutes for milk, as the calves do better on the more finely ground 

 commercial meal until several weeks of age. Then they can safely 

 be shifted to the cheaper home-mixed ration. Unless one is able 

 to grind the home-mixed ration fine, it seems best to use the com- 

 mercial meal, as the young calf does not seem to be able to endure 

 any considerable amount of coarsely ground feeds. 



This test will be repeated during the next fiscal year to get a 

 check on the data and to trv out some changes in the rations.
