Fourth Trial. 



Fed 5 days on cut hay daily 16 lbs. 



Oat straw cut, 32 lbs. hay value 16 " 



2 lbs. Indian meal, hay value 8 " 



Hay value of 5 days' food 200 " 



Deduct 6 lbs. not consumed 6 "

Cost of 5 days' food, hay at £ cent per lb $0.91 



Milk in 5 days, 48 6-16 lbs. 



Cost of milk, (hay at \ cent per lb.,) 1-9 cents per lb., or 3-9 cents the wine quart. The 

 hay, straw, and meal were given dry. The trial shows that hay, straw, and meal dry are not 

 so good for milk as when wet. 



February 3, 1852, commenced feeding two cows; one, 33 months old, 14 days after calving, 

 live weight 1000 lbs ; the other, 31 months old, 7 months after calving, not now in calf, live 

 weight 690 lbs. These cows were fed 5 days on 42 lbs., or 1\ per cent, of their live weight 

 of uncut hay, and 50 lbs. of flat turnips daily. 



Uncut hay daily 42 lbs.

Cost of 5 days' food, hay at £ cent, per lb $1.30 



Milk in. 5 days 153-6 lbs. 



Cost of milk, (hay at \ cent per lb.,) 0-846 of a cent per lb., or 1-6 cents the wine quart. 



Second Trial. 



Fed five days on cut hay. 



Cut hay daily 42 lbs. 



Turnips 50 lbs., hay value 10 "

Hay value of 5 days' food 260 " 



Deduct 5 lbs. not consumed 5 "

Cost of 5 days' food, hay at £ cent per lb , $1.27*5 



Milk in 5 days 152-2 lbs. 



Cost of milk, 0-837 of a cent per lb., or 1-6 cents the wine quart. 



The cows did not eat the hay quite so well as the long hay on the first trial, so that the 

 whole experiment shows a small difference in favor of cut hay. 



Third Trial. 



Fed same as second trial, except gave 3 lbs of Indian meal instead 



of 50 lbs. of turnips. 

 Cut hay daily 42 lbs. 



3 lbs. Indian meal daily, hay value 12 "

Hay value, 5 days' food 270 " 



Deduct 10 lbs. hay not consumed 10 "

Cost of 5 days' food, hay at J cent per lb $1.30 



Milk in 5 days 153 lbs. 



Cost of milk, (hay at £ cent per lb.,) 0-849 of a cent per lb., or 1-6 cents the wine quart. 

 This trial seems to prove that 3 lbs. of Indian meal are equal to 12 lbs. of English hay, or 50 

 lbs. of flat turnips, for milk. 



Fourth Trial. 



Fed cut hay daily 42 lbs. 



33 lbs. carrots daily, hay value 11 «
