82 STORRS AGRICULTURAL EXPERIMENT STATION. 
SUMMARY.—THE EXPERIMENTS AND RESULTS. 
Ln the winter of 1892-93, the Station began making systematic 
observations of the winter feeding practices of Connecticut dairy- 
men. The chief points upon which information was obtained 
were: Number of animals in the herd; breed, age, and approxt- 
mate weight of each cow, length of time since dropping last calf 
and till due to calve again, kinds, weights, and chemical compost- 
tion of feeding stuffs used; weights of milk flow, percentages and 
amounts of butter-fat in the milk. 
The feeding stuffs used on these farms included quite a long 
list, but those that tend to make a wide ration were employed in 
much greater proportions than were those which tend to make 
rations narrow. The following ts a nearly complete list. The 
nutritive ratios are calculated from the analyses made in the 
experiments taken, together with other analyses of like materials, 
as used in New England. The more nitrogenous materials are, 
of course, those richest in protein or ‘‘ flesh formers,’ while the 
more carbonaceous are those poorer in protein and having larger 
proportions of the fuel ingredients, t. e., fats, and especially the 
carbohydrates. The former, with smaller nutritive ratios (ratio 
of protein to fuel ingredients), tend to make narrow rations, while 
the latter make wide rations.

Ln 1892-93 sixteen herds were visited and a jive-days’ test was 
made with each. Ln 1893-94 six herds were visited, and tn four 
instances the time of study of the feeding, management, and 
products of each herd was extended to twelve days. As soon as 
the analyses could be made, the amounts of actual nutrients in the 
rations fed were calculated, and in three cases other rations were
