PREVIOUS FEEDING EXPERIMENTS WITH GREEN. FODDERS BY 
. Hiheol ss LION: 
During the summers of 1891 and 1892 the Station carried on 
a number of feeding tests with milch cows on different fodder 
crops. ‘The object of the experiments was to study the values 
of different green fodders for milk and butter production, and 
the effects of the rations on the milk product, with especial ref- 
erence to the quantity of fat produced. A small grain ration, 
mixed in most cases with cut hay or straw, was fed once a day. 
From fifty to seventy-five pounds daily per animal of the 
various green fodders were used. 
Four cows were used in these earlier experiments, and were 
all fed the same kind of fodder during each individual .period. 
In 1891 the feeding experiments were carried on from June 
8th to September 22d, and were calculated in four-day periods, 
although the same fodder was fed from twelve to sixteen days 
in nearly all cases, thus making up two or three four-day 
periods. In two tests with Hungarian grass the amounts of 
feed were limited, and the fodder could only be fed for seven 
or eight days in each case, leaving but one four-day period for 
the test. In 1892 the experiments were carried on from May 
29th to August 15th, and the test periods covered seven days. 
In each year three or four days were allowed as a preliminary 
period on each fodder, before the test was begun. All of the 
fodders were analyzed, although the digestion factors were 
assumed from the averages of work done elsewhere. In 1891 
the fats only were determined, and in 1892 both fats and 
solids were determined in the milk. 
The results in a general way pointed out quite forcibly the 
high value of nitrogenous green fodders, such as clovers, oats 
and peas, soy beans and cow peas for milk and butter production.
