TOTAL GAIN OR LOSS IN LIVE WEIGHT OF ANIMALS. (Ibs.)

English liay, +55 



The cows made quite a noticeable gain on the English hay ration. 



AVERAGE MILK AND BUTTER YIELD PER COW DAILY. (Ibs.) 



The influence of the black grass — a different sample from the one 

 previously reported on — is quite apparent. The ration containing 

 the cove hay mixture returns nearly as good results as the English 

 hay ration. Figured in the usual way, a ton of the mixture would be 

 worth about 8 per cent less than a ton of English hay. This agrees 

 with results returned by the sheep.
