The digestible nutrients and fuel viilue of the rations fed, the milk 

 and butter produced, and the cost of the latter for each of the 4: herds 

 are given in the following table: 



Original and suggested rations fed to cows on 4 farms in Connecticut. 



In addition to the above tests the results are cited of the previous 

 experiments already referred to. In all these the digestible protein 

 per 1,000 lbs. live weight ranged from 1.35 to 3.48 lbs., the nutritive 

 ratio from 1:4.5 to 1:11.3, and the fuel value from 28,000 to 42,000 

 calories. The average amounts of nutrients i)er 1,000 lbs. live weight 

 in these 34 rations were as follows: 



Average of 34 rations fed to cows in Connecticut. 



The article discusses feeding standards and quotes at length from 

 the previous experiments mentioned above. From their own exi)eri- 

 euce the writers suggest the following modification of Wolfi"'s standard : 



Organic matter pounds . . 25. 00 



Digestible protein do 2. 50 



Digestible fat do 0. 5 to 0.80 



Digestible carbohydrates do 13.0 to 12.00 



This gives a fuel value of 31,000 calories, and a nutritive ratio of 1 : 5.6. 



"The experience of the last two years would indicate that in general it is more 

 profitable to feed a cow in 'the flush' rather more protein than the suggested ration 

 calls for. The very decided trend of these experiments is toward nitrogenous 

 feeding." 



The conclusions drawn from the tests were practically the same as 

 those in previous years.
