7-25 ANNUAL REPORT OF NEW- YORK 



Excrements of Fattenwg Cattle. — Witli the object of informing 

 myself, and for the better understanding of my practice, I had 

 recourse to the following experiments during the years 1852 and 

 1853. Eight fair-sized fattening cattle were supplied daily with 

 18 lbs. oat straw, shells of oats, and bean-straw. 

 4 " rape-cake and bean-meal.

with which they drank about 70 lbs. of water each. The yield 

 from this in solid and liquid excrement was found to be, for every 

 100 lbs. fodder and water, 72i lbs. excrement, being about 10 tons 

 per animal during the year. I give the analysis of the excrement 



by Professor Way : —

 The next cattle under experiment were eight heifers which had 

 scarcely attained their full growth. After allowing a short time 

 for change of food, they gained evenly and steadily throughout 

 16 weeks, during which their weight increased from 7| to 9| cwt. 

 each (on the average), being 14 lbs. per week. They were sup- 

 plied with turnips or other green food at the rate of 60 lbs. per 

 day — with chopped straw, together with 4 lbs. rape-cake and 2 

 lbs. of bean-meal each per day for ten weeks; from this time, 

 during six weeks, to the conclusion of the experiment 3 lbs. each 

 per day of rape-cake in addition, making 7 lbs. rape-cake and 2 

 lbs. bean-meal per day for each. I supply the amount and de- 

 scription of food for 21 days, during which the 7 lbs. of rape and 

 2 lbs. of bean-meal per day to each were given : —
