in immature corn silage. When sunflower silage is compared with 

 mature corn, it is seen that the cows utilize slightly less protein from 

 sunflowers than from corn silage, whereas sheep utilize similar amounts. 



SUMMARY 



(i) Analysis of sunflower silage fed at the Idaho Agricultural Experi- 

 ment Station indicated that it compared very favorably with corn silage. 



(2) The digestible nutrients contained in sunflowers compare favorably 

 with the digestible nutrients in mature and immature corn. 



(3) The nutritive ratio is somewhat narrower in sunflower silage than 

 in mature or immature corn silage. 



(4) Sheep utilized slightly more nutrients in sunflower silage than did 

 cows under the conditions of this experiment. 



(5) Where both corn and sunflowers can be grown, the selection of a 

 silage crop should depend upon comparative tonnage per acre and cost 

 of harvesting.
