STANDARD RATIONS FOR DAIRY COWS. eae | 
the coarse fodders available for use must be taken into consid- 
eration before concentrated feeds can be purchased and used 
with the best results. The feeder, then, must be guided in 
part by the coarse fodders available for use. The rations, to 
be profitable, must also vary with the kind and condition of the 
stock to be fed, and the price received for their products. ‘The 
feeder must be guided largely by the market value of feeds, 
their manurial values, the returns that he receives for his 
products, and the feeding capacities and productiveness of the 
different animals of the herd. ‘The price of feeds at one time 
may be such as to make a wide ration more profitable than a: 
narrow one. Asa rule, however, when the direct animal pro- 
ducts and the manure are both taken into account, the liberal 
feeding of narrow rations, with large quantities of protein, is 
found to be the most profitable in Connecticut.

suggested feeding formulas, by the Station.

Animals differ widely in their feeding capacities, and the 
successful feeder must be a close observer, and must vary his 
feeds in accordance with the appetites of his animals. ‘The 
most vigorous eaters are generally the most profitable animals
