under the two systems approximate 243,140 for summer silage and 238,390 

 for Ladino clover pasture on areas equivalent in productive capacity. The 

 additional silage area would provide 10,409 T.D.N.; oats pasture 19,080; 

 and permanent pasture 112,500; a total of 141,989. Under a summer La- 

 dino pasture svstem, oats pasture would provide 27,284 and Ladino pas- 

 ture 94,000 units, a total of 121,284 T.D.N. 



Labor requirements are quite similar. For summer silage, an ap- 

 proximate total of 1086 hours of man labor is required to produce the feed 

 for 26 cows; while Ladino pasture would require 1116 hours of man labor. 



Estimated cash costs are as follows: 



Summer silage: Seed $ 88.00 



Fencing 25.00 



Fertilizer 531.00 



$644.00 



For Ladino pasture: Seed $116.00 



Fencing 10.00 



Fertilizer 597.30 



Total $723.30 



Lime costs could be maintained at nearly the same figure, about 25 

 tons annually, after the system had been established. 



The greater area of permanent pasture required for the summer 

 silage system should offset the greater labor and seed cost for Ladino pas- 

 ture for late summer feed. There would be some additional manure 

 available from stabling the cows while feeding silage.

Producing the Full Roughage Requirements on New 

 Hampshire Dairy Farms With Special Reference *o Pastures 



This project is being conducted on outlying dairy farms. During 

 1945, plots on seven farms were harvested and on three farms progress 

 was made in getting the pastures from a plot to a field scale. One or two 

 additional farms will be added in 1946, on which separate fields will be 

 seeded to one of the large grasses supplemented with Ladino clover. 



In a three-year summary covering the data for six grasses from all 

 the plots which have been harvested, smooth brome leads in total pounds 

 of forage produced, while timothy is last. A three-year summary fol- 

 lows:
