ANIMAL GROWTH AXD NUTRITION. 



247 



fed, cows. First period, given 2.5 pounds proteine, .5 of a 

 pound fat, and 12.5 pounds carbohydrates, each animal, and 

 in digestible amounts. 



Yield, lot 1. — 48.6 pounds milk. 

 2. — 49.7 pounds milk. 



In the" second period, 100 pounds of ensilage were given 

 to lot 2, in place of 40 pounds turnips, before eaten ; rations 

 of each otherwise the same. 



Yield, lot 1. — Second period, 51.3 pounds milk. 

 2. — Second period, 48.9 jiounds milk. 



The third period of five weeks, lot 1 was fed as before, 

 and lot 2 fed 120 pounds ensilage, each cow, and 5 pounds 

 cotton-seed meal. This furnished as much of each of the 

 nutrients as lot 1 had. It was all eaten. 



Yield, lot 1. — Third period, 48.4 pounds milk. 

 2. — Third period, 48.2 pounds milk. 



Here are exact facts, and in agreement with just what 

 scientific men have claimed ; and yet careless observation 

 will no doubt go right along laughing at science, and claim- 

 ing all by guess. One well-taken fact is worth all the 

 world's guessing. As I have ever been, without exception,

Professor McBrjde of the Tennessee University has gone 

 through an elaborate set of experiments too full to admit of 

 review. He fed ensilage alone, with the following result, for 

 thirty days : — 



A bad showing, and worse than I came out with by straw, 

 and evidently worse than my results with stover alone, from
