Feeds and Feeding. 



We observe that when the cows were changed from good hay to 

 silage and hay their milk flow increased 7 per ct., and when changed 

 back it decreased 8 per ct. In this trial 440 lbs. of corn silage proved 

 somewhat superior to 100 lbs. of good hay (mostly timothy). Jordan 

 holds that when good timothy hay is worth $10 per ton, average corn 

 silage is worth $2.62 per ton. 



In an extended trial with 6 cows Hills of the Vermont Station^ 

 found that w^hen 3.5 lbs. of corn silage was substituted for 1 lb. of 

 mixed timothy, red top, and clover hay, the milk yield was increased 

 7 per ct. Rating hay at $10 and silage at $3 per ton, there was a 

 gain of 1.66 cents daily per cow by replacing one- third of the hay 

 with silage. From available data it is fair to conclude that for dairy 

 cows 100 lbs. of good mixed hay is worth as much as 400 to 450 lbs. 

 of average corn silage. 



656. Corn silage v. sugar beets. — Haecker of the Nebraska Sta- 

 tion- compared corn silage and sugar beets with 2 lots of 5 cows 

 each, fed for a period of 5 weeks with the results shown below. The 

 concentrates consisted of equal parts of oats, corn, and wheat bran. 



Corn silage compared with S)(ga7- hrefs. 



It is shown that where 30 lbs. of corn silage was fed against an 

 equal weight of sugar beets, the small difference in yield of milk 

 and fat w^as in favor of the silage. (352, 563) 



657. Apple-pomace silage. — Hills of the Vermont Station^ fed as 

 much apple-pomace silage as the cows would consume in addition to 

 8 lbs. of grain and 10 to 12 lbs. of hay. On apple-pomace silage the 

 cows consumed somewhat more dry matter than those getting corn 

 silage, with a corresponding increase in milk flow. The apple-pomace 

 silage had no deleterious influence on the cows or their milk. Lind- 

 sey of the Massachusetts (Hatch) Station^ holds that apple-pomace 

 silage is equal to average corn silage in feeding value. (360)
